SSAW Pipe

 In the hot and hot weather in summer, there is a lot of rain, and the weather is more hot and humid after the rain. In this state, the surface of galvanized products is prone to anti-alkali (commonly known as white rust) phenomenon. If the plated goods are not picked up in time, if they are not unpacked and used in time when they arrive at the destination, the phenomenon of anti-alkali will easily occur to prevent irresistible losses. The service life of galvanized steel pipe is generally 8-12 years, with an average service life of 10 years, and it can be extended in dry environment. In rainy and foggy weather, try to store or cover indoors as much as possible. After the rain stops and fog is dispersed, the sheet should be removed to keep it ventilated and dry; avoid direct contact with wet soil when stacking. Treatment methods for galvanized products entering water and damp: 1. If the whole piece is exposed to water, it should be disassembled immediately and placed in a ventilate...

　　Coat-Plating Methods of Galvanized steel Pipes 　　Hot dip galvanizing can protect steel pipes very well. When zinc is in liquid state, plate the steel with a thick layer of pure zinc after the complicated physical and chemical interaction and thus will make the hot dip galvanizing come into being. Also a zinc and steel alloy layer will be generated during this process. With this kind of layer and corrosion resistance feature, galvanized pipes can be applied to different severe corrosion environments, such as strong acid, alkali frog, etc., which is incomparable to other electro galvanizing. 　　Advantages of hot dip zinc galvanized pipes： 　　First, in general atmosphere, a very thin and dense layer of zinc oxide will be formed on the surface of zinc coating. It is hard to dissolve in water, therefore plays a certain protective effect to steel substrate. So, if the surface of steel pipe is covered with a quite thick and dense pure zinc layer, the steel substrate will be protected fr...

　　 Hot Dip Galvanizing 　　Since the standard electrode potential of zinc is lost to iron, galvanized layers in water and humid air have sacrificial anodes to protect the steel base, which can greatly extend the service life of the steel. Commonly used in the industrial galvanized layer of hot-dip galvanized, electro-galvanized, mechanical galvanizing and thermal spraying (plating) zinc, which accounted for about 95% of the total amount of hot-dip galvanizing, Accounting for 40% of zinc production in the world, accounting for about 30% of China's zinc production. 　　 Hot dip galvanized steel pipe , stainless steel, cast iron and other metals immersed in molten liquid metal or alloy in a coating technology. Hot-dip galvanizing, also known as hot-dip galvanizing, is a method in which a steel member is immersed in a molten zinc solution to obtain a metal coating. With the rapid development of high-voltage transmission, transportation and communication, the requirements for the protec...

　　Black steel pipe and galvanized steel pipe have several respects similar to each other, such as they are common kind of pipe applied to transport liquid and gas, so there are many people can't distinguish them clearly. 　　The main difference between black steel pipe and galvanized steel pipe: 　　Black steel pipe and galvanized pipe all use steel as raw material. And general speaking, galvanized steel pipe is more expensive and more durable since galvanized pipe has a zinc coating while black pipe does not. Galvanized pipe covered with a layer of zinc which makes it have higher ability of corrosion protection and help to prevent the accumulation of mineral deposits that will block the pipe.This will lead to a burst. So galvanized steel pipe is more suitable for carrying water instead of gas. 　　For transportation, galvanized pipe is mainly used for carrying water to supply home and commercial buildings. It is also serve as scaffolding frames because of its rust prevention. Bla...

　　(1) Carbon; the higher the carbon content, the higher the hardness, but the worse its plasticity and toughness. 　　(2) Sulfur; it is a harmful impurity in steel. When steel with high sulfur content is subjected to pressure processing at high temperature, it is easy to be brittle and is usually called hot brittleness. 　　(3) Phosphorus; can significantly reduce the plasticity and toughness of steel, especially at low temperatures, this phenomenon is called cold brittleness. In high quality steel, sulfur and phosphorus should be strictly controlled. However, from another point of view, the inclusion of higher sulfur and phosphorus in low carbon steel can make it easy to cut, which is beneficial to improve the machinability of steel. 　　(4) Manganese; can improve the strength of steel, can weaken and eliminate the adverse effects of sulfur, and can improve the hardenability of steel, high alloy steel (high manganese steel) with high manganese content has good wear resistance And othe...

　　The biggest difference between water gas pipeline and galvanized steel pipe is that the former is seamed steel pipe and its pressure bearing capacity is low, the later is seamless steel pipe and its pressure bearing capacity is high. 　　Water gas pipes are constituted by welded steel pipes with thick wall, its materials are different from galvanized steel pipes. Water gas pipe is made of low-carbon steel welded pipe. those Galvanized are called galvanized iron tubes. Those non-galvanized are called black pipes. 　　Galvanized steel pipe is divided into cold galvanized steel pipe and hot galvanized steel pipe. The electroplating of hot galvanized steel pipe is relatively strong, its zinc layer is thick, and there is a blue ring logo on the head of galvanized pipe. Cold galvanized steel pipe is also made by electroplating, but it is made with less technology, and its performance is far worse, no blue logo. Cold galvanized steel pipe has been banned, hot galvanized steel pipe is promo...

　　The total zinc coating condition applied depends mainly on the mass and thickness of the galvanized steel tubing. Usually the surface of the galvanized layer should be complete and uniform and with a standard thickness. The evaluation of the appearance quality of the galvanized layer is very important. The following listed the common surface conditions of the galvanizing layer for galvanized steel pipe . 　 　1. Gray and dark-gray cobwebbing 　　The chemical elements of the steel tube such as C, Si, P and Mn will cause Fe-Zn alloy reaction with the increase of the content, produced zinc-iron alloy layer on the coating surface, especially with Si increased, which accelerate the reaction of iron-zinc melt mutually, formed on the surface of gray even the black net. The black coating layer is thicker than the bright coating, the corrosion protection and prevention ability completely inferior to the bright coating, but will be more resistant to corrosion but may not pretty sensually.
