Welding technology of stainless steel welded pipe is significant.  Some knowledge is introduced as follows to ensure you have a better understanding of stainless steel welded pipe.  As for what is included, please read on. A. Equipment a. If it is argon arc welding, then direct current infusible argon arc welding...

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....

Some proposals for stainless steel pipe procurement    1. Various performance indicators (mechanical properties, wall thickness, surface): in fact, as a seller, it is good enough to know what is the material and surface of goods. It is not realistic for them to know all various performance indicators. So, I suggest...

With constant development of the national economy construction, the stainless steel tube is more and more widely used in all kinds of industries. Based on the stainless surface passivation layer corrosion resistant capacity analysis, and combined with the use of small health level of seamless stainless steel pipe technology...

Generally, everyone hold a view that magnet adsorb stainless steel tube in order to verify its quality and authenticity. If the magnet does not adsorb stainless pipe, then, it is considered as a good stainless steel pipe. If not, it is considered as a fake stainless steel pipe. As a matter of fact, this is a very one-sided,...

Large diameter, thick wall and high grade double-sided UOE Pipe is widely used in China in the field of steel structure in the nearly five years. China is focusing on advanced design concept of imported steel structure, attaching great importance to developing seam steel pipe as hardware. Double-sided UOE Pipe is applied...

Our country shipbuilding industry occupies an important position in the national economic development. A study shows that shipbuilding industry products involved 97 industries, accounting for 87% among 116 industries, such as metallurgy, materials, machinery, microelectronics, electric, hardware, textile, chemical industry,...

As an important part of iron and steel products, steel pipe plays an essential role in the development of national economy. According to the different forming process, welding method and the used tube billet shape, steel pipe can be divided into the following kinds: large diameter seamless pipe, ERW steel pipe and spiral...

Hot rolled strip steel of SSAW (Spiral seam submerged arc welding steel pipe) is bent according to the spiral shape. Then, spiral seam welded steel pipe which is also called spiral welded pipe, spiral pipe, spiral steel tube is made by the inseam and outer seam of automatic submerged arc welding. For the following reason,...

With the rapid development of economy in China and the increase consumption of stainless steel, demands for stainless steel pipe also increase. The stainless pipe market prospect is good.   Stainless steel seamless tube market demands come from basic industries, such as petroleum, chemical industry, power generation....

1．Welding material According to 15CrMo Steel weldability, on-site working characteristics of high pressure pipeline and reference to welding process card provided by abroad, we select two kinds of schemes to conduct the welding test based on past experience.   SchemeⅠ: First, conduct the welding preheating method....
