After hot-dip galvanizing of steel structure, it is equivalent to one-time annealing treatment, which can effectively improve the mechanicalof steel matrix, eliminate the stress during steel forming and welding, and is conducive to turning of steel structure.

0The use of hot dip galvanizing has expanded with the development of industry and agriculture. Therefore, hot-dip galvanized products have been widely used in industry (such as chemical equipment,Products Show petroleum processing,Jonkiel40Cr seamless pipe factoryThe pros and cons and how to improve the quality marine exploration, metal structure, power transportation, shipbuilding, etc.), agriculture (such as sprinkler irrigation, heating room), construction (such as water and gas transportation, wire casing,Products Show scaffold, house, etc.), bridges, transportation, dead end welding of strip steel and circumferential seam. For the spiral welding of steel for the transportation of flammable general liquids, yibai%sx ray or ultrasonic testing shall be carried out. For the spiral welding of alloy pipes for the transportation of water, wastewater, gas, heating steam and other general liquids,Products Show X-ray or ultrasonic testing sampling inspection (%) shall be carried out.

There are many types of galvanized pipes, mainly including cold plated seamless pipes and hot-plated seamless pipes. But now the previous one is no longer used. The hot-dip seamless tube is still in use. Hot dip galvanized pipe is mainly used for steel pipes with low pressure fluid such as water and gas. When in use,Jonkiel40Cr seamless pipe factoryThe pros and cons and how to improve the quality the thickness of galvanized layer of hot-dip galvanized seamless steel pipe is up to μ M above, and it has been used safely for about years. It can be seen that its service life is very long. Of course, when purchasing, we should also find regular manufacturers to order. Only in this way can we achieve this service life. As long as the galvanized pipe is cleaned after pickling, it is basically cleaned in ammonium chloride or zinc chloride aqueous solution or ammonium chloride and zinc chloride mixed aqueous solution tank. In order to ensure the quality, electro galvanizing will not be used. There are also some small enterprises in the market. They will use electro galvanizing in production. In this way, although it is much cheaper in price. However, the quality is very good when used,Reinforcement, galvanized pipe, seamless pipe, welded pipe, alloy pipe, I-beam-Shandong Kaiwen metal material Co., Ltd and it is also easy to have problems.

LSkilatThe development of steel bar mesh is in line with the development of energy-saving economy

DuGalvanized pipe: the zinc layer of cold galvanized pipe is an electroplating layer, and the zinc layer is separated from the steel pipe substrate. The zinc layer is very thin. The zinc layer is simply attached to the steel pipe substrate and is easy to fall off. Therefore, you can choose an incomplete performance outside the product. Some construction experts claim that if there is a mechanical effect on these products, they are not suitable. At least this product is impossible.

In view of the current market environment, especially in terms of construction or equipment manufacturing technology, the position of galvanized pipe is still relatively large. It is precisely because of this strong position that we can see this kind of building material in all walks of life, even in a field that seems to have little contact. It will be applied in many construction projects. At the same time even in the depressed environment of the steel industry, the application situation and utilization rate of this kind of pipe are very high.

j→ I-beam can be processed into T-beam, and honeycomb beam can be combined to form various section forms, which greatly meets the needs of engineering design and manufacturing.

RSteel pipes can be classified by their models:

Tassets Simple section steel pipe -- circular steel pipe, square steel pipe oval steel pipe, triangular steel pipe, hexagonal steel pipe, rhombic steel pipe, octagonal steel pipe, semi-circular steel pipe, others.

wW The reinforcement on both sides of the inverted beam extends into the beam respectively, and the anchorage length of the reinforcement is the same as that of the reinforcement, without hook.

In order to improve the corrosion resistance of steel pipe, the general steel pipe (black pipe) is galvanized. The galvanized pipe is divided into hot-dip galvanizing and electric steel zinc. The hot-dip galvanizing layer is thick and the cost of electric galvanizing is low, so there is galvanized pipe.

The allowable deviation of vertical installation of galvanized pipe is mm per meter, and the allowable deviation above m is no more than mm. The allowable deviation of horizontally installed pipes is mm per meter.

Manufacturing costnThe reinforcement mesh of the maintenance platform has the characteristics of extensive application, beautiful style, checkered plate guard plate Skirting plate (edge guard plate), installation of connectors and other accessories can be added around. The reinforcement mesh is suitable for the reinforcement mesh manufactured in the factory and welded with cold-rolled ribbed reinforcement or cold-rolled smooth round reinforcement. The welded reinforcement mesh for reinforced concrete is a good and efficient material for concrete distribution. Flat steel with different specifications can be used for edge wrapping, Or wrap edges with angle steel, channel steel, square tube, etc; Handles and hinges can also be installed on the reinforcement mesh that needs to be moved or opened frequently.

DGenerally, the process of pickling and passivation will be carried out for alloy pipes but the alloy pipes after pickling and passivation are very easy to rust. Therefore, the way to find a solution to wiredrawing corrosion is "grinding and polishing". Due to grinding and polishing, there is no harm to carry out hot galvanizing in the middle and later stage.

Galvanized pipe is a name for square pipe, that is, steel pipe with equal side length. It is made of rolled strip steel after process treatment. Steel pipe has been an essential material in building decoration. Galvanized pipe is also used more in decoration, but hot-dip galvanized steel pipe manufacturers need to know about the size of galvanized pipe and several common sizes of galvanized pipe, which is helpful for your purchase!

hGranby The vertical of the processed reinforcement bar shall be divided into small sections as required.

eGThe use of welded steel mesh can make the project construction convenient. As long as the welded reinforcement mesh is laid as required, the concrete can be irrigated, eliminating the links such as on-site cutting placing and binding of reinforcement one by one.

The storage of galvanized pipes should pay attention to several points. The first is the storage location. It cannot be placed in the open air, because in the open air, not only the safety of various products such as theft, but also corrosion problems will occur. Open air sites are vulnerable to various extreme weather conditions. Large amounts of rain or snow will erode the zinc coating on the surface to the greatest extent, which may lead to rust of the product. The second is the details of storage. It is not directly exposed to the sun. It shall be cooled and dried and shall not be stored with corrosive articles.
