Production process of spiral steel pipe is complex, but it is one of the most popular steel pipes because it can be used widely. Spiral steel pipes are produced through welding process, then what issues should be noticed in the welding process? Let’s find out these questions one by one. Straight seam welded pipes...

Precise stainless steel pipe refers to stainless steel pipes with austenitic organization in normal temperature. Stainless steel tubes contain about 0.1% C, 18% Cr, 8% ~ 10% Ni, with stable austenite organization. Common heat treatment technologies are: solution treatment, stabilizing treatment and stress relief treatment. ...

Corrosive forms of sanitary stainless steel tubes mainly includes crevice corrosion, pitting corrosion, balanced corrosion,  intergranular corrosion and stress corrosion, etc. Crevice Corrosion Crevice corrosion refers to local corrosion caused by electrochemical imbalance of the medium in the seams of sanitary ...

Precise stainless steel pipe is safe and reliable, sanitary and environment protecting and affordable. Thin wall of pipe and successful development of new methods for reliable, simple and convenient connection endow it with many irreplaceable advantages. And the application in project will be more and more frequent and...

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,...
