The thickness of hot-dip galvanized layer

The thickness of hot-dip galvanized layer is the total thickness of the zinc and zinc-iron alloy coating on the steel surface, expressed in km. Hot-dip galvanized steel pipe is the only galvanized steel pipe that can be used for water transportation cold drawn seamless steel tube. It has not been eliminated or controlled now because the galvanized steel pipe has a thick galvanized layer and will not be rusted for a long time. In other cases, the safety is high, and the thickness of the steel pipe galvanizing is carried out in accordance with national standards. Let us look at the specific standards.

According to the main surface area of ​​the hot dip galvanized parts, the thickness of the coating measured by the test should meet the following requirements:

For parts with a major surface area greater than 2 m (ie large pieces), the average thickness of the plating measured in all basic measuring surfaces (see 3 – 7) of each part in the sample shall not be less than Table 2 or Table The minimum value of the corresponding average coating thickness in 3;

Note: The length of corrosion protection of the hot dip galvanized layer is roughly proportional to the thickness of the coating. For parts that are serviced under extremely harsh conditions and/or require longer service life, the coating thickness requirements may be higher than those specified in this standard. However, the thickness of the galvanized layer is limited by factors such as the chemical composition of the substrate, the surface condition of the part, the geometry of the part, and the hot dip plating process parameters.

1. Formation mechanism of hot-dip galvanized coating

Hot dip galvanizing is a metallurgical reaction process. From a microscopic point of view, the hot dip galvanizing process is two dynamic balances: heat balance and zinc-iron exchange balance. When the steel workpiece is immersed in molten zinc liquid at about 450 ° C, the workpiece at normal temperature absorbs the heat of the zinc liquid. When it reaches 200 ° C or higher, the interaction between zinc and iron gradually becomes obvious, and zinc penetrates into the surface of the iron workpiece. As the workpiece temperature gradually approaches the temperature of the zinc liquid, an alloy layer containing different ratios of zinc to iron is formed on the surface of the workpiece to form a layered structure of the zinc coating layer.

Different alloy layers exhibit different growth rates over time. From a macroscopic point of view, the above process is characterized in that the workpiece is immersed in zinc liquid, and the zinc liquid surface appears to be boiling 150×150 mild steel square pipe. When the zinc-iron reaction is gradually balanced, the zinc liquid surface gradually calms. When the workpiece is raised with a zinc liquid surface and the workpiece temperature is gradually lowered to below 200 ° C, the zinc-iron reaction stops, the hot-dip galvanized coating is formed, and the thickness is determined.

2. hot-dip galvanized coating thickness requirements

The main factors affecting the thickness of zinc coating are: matrix metal composition, surface roughness of steel, active silicon and phosphorus content and distribution in steel, internal stress of steel, geometry of workpiece, hot dip galvanizing process. The current international and Chinese hot-dip galvanizing standards are divided according to the thickness of the steel. The thickness of the zinc coating and the local thickness should reach the corresponding thickness to determine the corrosion resistance of the zinc coating. For workpieces with different steel thicknesses, the time required to achieve thermal equilibrium and zinc-iron exchange balance is different, and the thickness of the formed coating is also different. The average thickness of the plating in the standard is an industrial production experience value based on the above-described galvanizing mechanism, and the local thickness is an empirical value required in consideration of the unevenness of the thickness distribution of the zinc plating layer and the corrosion resistance requirement of the plating layer. Therefore, the ISO standard, the American ASTM standard, the Japanese JIS standard, and the Chinese standard have slightly different zinc coating thickness requirements, which are similar.

3. The effect and influence of the thickness of hot-dip galvanized coating

The thickness of the hot-dip galvanized coating determines the corrosion resistance of the plated part. For a detailed discussion, please refer to the relevant data provided by the American Hot Dip Galvanizing Association. The user can choose a zinc coating thickness above or below the standard. For thin steel sheets with a smooth surface of 3 mm or less, it is difficult to obtain a thick coating in industrial production. In addition, the thickness of the zinc coating which is not commensurate with the thickness of the steel affects the adhesion of the coating to the substrate and the appearance quality of the coating. Excessively thick coatings can cause the coating to be rough and easily peeled off, and the plated parts cannot withstand collisions during handling and installation.

If there are more active elements such as silicon and phosphorus in steel, it is very difficult to obtain a thin coating in industrial production. This is because the silicon content in the steel affects the growth mode of the alloy layer between zinc and iron, which will make the phase zinc-iron alloy layer. Rapid growth and pushing the phase to the surface of the coating results in a rough and matte surface, forming a dark coating with poor adhesion.

Therefore, as discussed above, there is uncertainty in the growth of the galvanized layer. It is often difficult to obtain a certain range of coating thickness in actual production. The thickness specified in the hot-dip galvanizing standard is an empirical value generated after a large number of experiments. Taking care of various factors and requirements, it is more reasonable, the standard content of hot-dip galvanized layer thickness is here, I hope to help everyone.

Maintenance of photovoltaic power plants

Under the severe weather of strong humidity, constant rainfall and thunderstorms, if the operation and maintenance of photovoltaic power plants are not systematically carried out galvanized square tube suppliers, it is easy to cause safety hazards. How to deal with them?

1, smog

In the case of plum rain or smog weather and low solar radiation, if the operating voltage of the photovoltaic system does not reach the starting voltage of the inverter, the photovoltaic system will not work. Since the grid-connected power generation system is connected to the grid, when the photovoltaic power generation system is unable to operate, the grid’s electricity will be automatically replenished, so there is no shortage of power and power outage in the rainy weather and smog.

2, lightning strikes

Lightning is mainly divided into two types of hazards: direct lightning strikes and indirect lightning strikes. Direct lightning protection: Set up metal lightning protection grounding conductors on tall buildings, including lightning rods, lightning protection belts and grounding devices, which can release the huge thunderstorm cloud layer charge. All electrical equipment in a photovoltaic system is not protected against direct lightning strikes. Protection of inductive lightning: The photovoltaic system has lightning protection modules in electrical equipment such as combiner boxes and inverters to protect against indirect lightning strikes. The inverter has two-level lightning protection and three-level lightning protection. click The second-level lightning protection adopts lightning protection module. It is generally used for medium and large-scale photovoltaic power stations. There are no high-rise buildings around the power station, and lightning protection devices are used for three-level lightning protection. It is used in small-scale photovoltaic power plants for household use, and there are high buildings around the power station.

Distributed photovoltaic power generation systems are equipped with lightning protection devices, and normal lightning weather does not need to be disconnected. If there is a strong thunderstorm, for safety insurance, it is recommended to disconnect the DC switch of the inverter or the combiner box to cut off the circuit connection with the PV module to avoid the hazard of the induced lightning. The operation and maintenance personnel should normally check the lightning protection facilities to ensure the normality of the lightning receptor, the down conductor and the grounding system, and ensure that the short circuit resistance of the lightning protection grounding system is below 4 ohms, and the performance of the lightning protection module in the equipment is periodically checked. Prevent failures, which will ensure that thunderstorms will not damage the equipment.

3, heavy rain

If the roof of the PV power plant is installed as a sloping roof, there is basically no need to worry about the rainstorm. If it is a flat roof, it is best to consider the drainage problem when designing and installing the PV power station. When the rainfall is too large, the installation of the flat roof is relatively low, so that the PV modules are soaked by rain. In addition, during the inspection after the rain, do not directly touch the connection between the inverter, the PV module and the power supply cable by hand, and wear rubber gloves and rubber boots to prevent accidents.

4, hail

Photovoltaic modules are tested for impact from qualified photovoltaic power plants purchased from reliable large manufacturers, so hail will not affect PV modules. However, after the hail, daily inspections are indispensable. If the photovoltaic power station has a significant drop in power generation or other abnormal conditions after the hail, the owner must notify the factory after-sales personnel to conduct the test.

When inspecting a photovoltaic module, the thermal imaging portion is generally used to lock the heat generating portion, or the disconnection detector is used to check the disconnection portion and the bypass diode failure. If the power generation is significantly reduced or other abnormal conditions occur after the component is smashed, the user should promptly notify the operation and maintenance personnel to check the PV system, and if necessary, return it to the original factory for testing, so as to replace the damaged PV module in time.

What can be done to build a photovoltaic system power station to ensure stable power generation and weather resistance?

1, Do the early design of the power station: When designing the photovoltaic power station, you need to choose a suitable location. For example, if the photovoltaic power station is built on the roof, it should be considered that the roof fixed load, wind pressure load, snow pressure load, and seismic load are generally “Building Structure Load Specification”, because this is the only way to avoid damage to the power station due to rain and rain.

2, do the installation work: the installation can not be arbitrary, the installation process of the power station should be southward, so that it can fully accept the sun’s light. The installation angle is theoretically equal to or close to the local latitude, and the arrangement and spacing need to be combined with the local sunshine and roof structure dimensions. In addition, we must choose good equipment to effectively extend the life of photovoltaic power plants.

All in all, in order to stabilize the photovoltaic power station in the continuous bad weather, it is necessary to design according to the design, installation and selection, in order to prevent the damage of the photovoltaic power station, and let the power station easily pass the season of frequent rain. Steady operation and security.

American Energy Opportunity Act

US Senators Martin Heinrich (D-NM) and Susan Collins (R-ME) presented the American Energy Opportunity Act, which will give deliberate help and instruments to neighborhood governments to improve, C profile Manufacturers and Suppliers institutionalize and mechanize clean vitality allowing for occupants and organizations while upgrading wellbeing.

The enactment expands on the Solar Automated Permit Processing (SolarAPP) activity propelled by SEIA and The Solar Foundation a year ago. The objective for both SolarAPP and the American Energy Opportunity Act is to disentangle the procedure for allowing and investigating dispersed sun based and battery establishments through a free, generally accessible web based allowing gateway for nearby governments.

“In the event that we really need conservative clean vitality at a nearby level, we have to streamline the allowing procedure for conveyed vitality innovations like housetop sun oriented,” said Heinrich, Ranking Member on the Senate Subcommittee on Energy. “The present interwoven of allowing necessities crosswise over neighborhood purviews causes postponements and expands costs for both nearby governments and the organizations and property holders who need to construct littler scale sustainable power source frameworks. I am glad to acquaint bipartisan enactment with assistance state and nearby governments decrease pointless expenses and systems so as to advance little scale matrix modernizations in networks in New Mexico and the country over.”

“Sun based vitality is a demonstrated and integral asset in the battle against environmental change,” Collins said. “The American Energy Opportunity Act would help spike the reception of this innovation by giving gainful instruments to streamline the allowing procedure at the metropolitan level, which will help drive down the shrouded expenses of introducing housetop sun oriented. This bill, combined with the BEST Act we acquainted recently with advance cutting edge vitality stockpiling, holds the possibility to release the guarantee of spotless, sustainable power source all through the nation.”

Today, interconnection, allowing, and review procedures means about $7,000, or $1.00 per watt, in immediate and roundabout expenses to a run of the mill private sun oriented vitality framework. This builds establishment costs for customers and smothers property holder and business interests in clean vitality.

“This bill is a success win-win for purchasers, neighborhood governments, and clean vitality organizations. Neighborhood governments and building examiners don’t generally have the assets they have to go from allowing a kitchen redesign to allowing a close planetary system,” said Abigail Ross Hopper, president and CEO of SEIA. “This bill will give instruments to improve the sun based allowing process the country over, decreasing expenses for customers while upgrading security and quality. This implies more individuals and organizations can convey sun oriented quicker and better.”

The tax on steel in US

These import duties could bring about lower benefits for all organizations that utilization these hot dipped galvanized steel coil metals in their assembling forms, prompting more expensive rates for purchasers, or a blend thereof. While the President’s arrangement requires a 25 percent tax on steel and a 10 percent levy on aluminum, without any exclusions for any nation, examiners state Trump’s proposition is inadequate on subtleties.

The Trump plan is intended to build benefits for U.S. metal producers. Be that as it may, experts dread this could cause U.S. buyers of steel and aluminum to lose cash, as U.S. metal creators would have expanded valuing power with imported metals ending up increasingly costly. Furthermore, aluminum expenses are nearly ensured to ascend as practically the majority of that metal is imported.

Scott Wine, CEO of Polaris Industries Inc., a producer of snowmobiles and ATVs, says his organization spends over $300 million every year on steel and aluminum. Wine says the duties would raise his organization’s costs an expected one percent, which he feels is reasonable. Be that as it may, Wine says Polaris would need to figure out how to manage the conceivable cost increments from their residential metal providers.

U.S. development organizations and automakers could be among the most affected by the duties. In 2017, the U.S. development industry represented roughly 40 percent of U.S. metal utilization and the auto area represented a little more than 25 percent. Be that as it may, U.S. Business Secretary Wilbur Ross said the impact of the taxes would be minor, calling attention to that the one ton of steel used to make a normal vehicle would minuty affect generally speaking vehicle costs.

Deals or Profits?

In view of research directed by counseling firm Ducker Worldwide, the run of the mill American-made vehicle weighs generally 1.9 tons, or 3,835 pounds. This separates to 54 percent steel and 11 percent aluminum. Notwithstanding, delivering parts prompts squander, which raises costs further.

In general, Ducker gauges U.S. carmakers devour 2,925 pounds of steel and 526 pounds of aluminum to fabricate a normal vehicle. On the off chance that these numbers confirm, automakers should balance the greater expense by raising costs, which could contrarily affect deals, or tolerating a lower net revenue. Be that as it may, Joseph Amaturo, an investigator with Buckingham Research Group, expresses the Trump Administration’s new duties could include $300 per vehicle, which works out to about one percent, similar numbers refered to by Wine and Secretary Ross.

The Broad Market

The new duties could influence everything created in the U.S. that contains any steel or aluminum, or a rate thereof. Numerous items contain metal amalgams, which contain a level of steel as well as aluminum. With combinations being increasingly costly to fabricate in any case, levies could substantially affect everything from tractors to fish jars.

JP Morgan experts state the proposed duties could place an imprint in both Caterpillar and John Deere tractor deals by as much as nine percent. Edward Jones examiners state the new import expenses would influence nourishment costs too. Aluminum taxes would can possibly raise costs around seven percent for bottling works, particularly those whose biggest market is the U.S.

By and large Earnings

As indicated by securities exchange experts, levies are probably not going to fundamentally affect Corporate America. Keith Parker, an investigator for United Bank of Scotland, with workplaces all through the U.S., says the effect on all out corporate income is driven by the general economy. This is affirmed by enormous organizations neglecting to change their profit appraisals following the President’s declaration. Scott Wren, value strategist at Wells Fargo, says there will be repercussion from the levies, however it won’t be the part of the arrangement unhappiness and fate some are anticipating.

The use of stainless steel pipes

Nowadays, many industries in the urban area have been greatly developed. For example, in some industries, people are demanding the use of stainless steel pipes. The role of such stainless steel pipes will become more familiar. Of course, This kind of production will be more common, so in this kind of situation, everyone will not despise this aspect, then in this kind of situation, everyone will become more familiar with the schedule 80 stainless steel pipe.

This kind of product can be used in some places, and it has also been concerned. The original people can find that in the automated instrumentation information tube, there are still people who can find the location of the automatic instrument wire protection tube. Those who are interested in such products, and who will care about such products, will become more familiar and familiar later, and those who will care about such a product will become more familiar with them, so that such products can play a larger role. effect.

The role of such a product can not be underestimated, and at the same time, it is more obvious in terms of characteristics and characteristics. It has corrosion resistance and high temperature resistance. It is because of such a characteristic that such a Only in this way can we carry forward the role of increasing the amount of material. Nowadays, the production and development of such a material is also very big. Under such conditions, everyone will become more familiar with such a material, so it is said that Under such circumstances, such a product can really reach a very good role, and people who care about such a product will be more and more in the future.

What is the role of the components in the stainless steel tube? The characteristics of the stainless steel tube and the combination of the effect and the effect of the stainless steel tube are only one type of chromium. Each type of stainless steel contains a certain amount of chromium. There is no stainless steel containing no chromium. Chromium has become the key component of the decision-making function of stainless steel. The fundamental reason is to add chromium as an alloy component to the steel, and promote its internal conflicting trend to resist the development of erosion. This kind of transformation can get the footnote from the following aspects: chromium increases the electrode potential of the iron-based solid solution, and chrome extracts iron electrons to passivate the iron.

Passivation is due to the phenomenon that the corrosion resistance of metal and alloy is increased due to the blockage of the stainless steel tube anode reaction. There are many comments on the metal and alloy passivation, focusing on thin film theory, adsorption theory and electronic alignment theory.

Carbon is one of the key components of industrial stainless steel pipes. The function and combination of stainless steel pipes are determined at a large level in the content of carbon in steel and its dispersion mode. The carbon in stainless steel pipes is particularly prominent. Carbon in stainless steel The focus of the combination on the two aspects is presented in two aspects, carbon is a stable austenite composition, and the level of action is very large.

On the other hand, due to the high affinity of carbon and chromium, and chromium caused a series of complex carbides. Therefore, from the two aspects of strength and corrosion resistance, the role of carbon in stainless steel is conflicting.

The center of photovoltaic offices

Sun powered photovoltaic frameworks, otherwise called photovoltaics, alluded to as photovoltaics, allude to offices that convert sun based vitality into direct current vitality utilizing the photovoltaic impact of photovoltaic semiconductor L Profile steel materials. The center of photovoltaic offices is sun oriented boards. At present, semiconductor materials utilized for power age predominantly include: single gem silicon, polycrystalline silicon, indistinct silicon, and cadmium telluride.
