Forming method of submerged arc steel pipe:Submerged arc steel pipe forming methods include continuous twist forming (HME), row roll forming method (CFE), UingOingExpanding forming method (UOE), roll bending forming method (RBE), JingCingOingExpanding forming method (JCOE), etc., but the most widely

1.316 stainless steel is a molybdenum-containing stainless steel. Due to the molybdenum in the steel, the overall performance of this steel is better than that of 310 and 304 stainless steel. Under high temperature conditions, when the concentration of sulfuric acid is lower than 15% and higher than

1. IPN8710 anti-corrosionWhen there are many types of corrosive media in the steel pipe, such as acid, alkali, salt, oxidant, and water vapor, the coating must be chemically inert and resistant to acid, alkali, and salt corrosion. The coating film should have a dense structure, good waterproof perme

1. Distinguish welded steel pipes and seamless steel pipes according to the process.In the process of identifying welded steel pipes and seamless steel pipes according to the process, all-welded steel pipes are welded according to cold rolling, extrusion, and other processes. Spiral pipe welding and

Many cooperations have given the customer full confidence in THREEWAY STE

In our daily life, we will use many water pipes, and the spiral steel pipe is one of them. What should we do if the spiral steel pipe is blocked when we use it? When the pipe is blocked, it will not only affect us It will also have a corrosive effect on some raw materials inside the pipeline. Theref

The spiral steel pipe feeds the strip into the welded pipe unit. After rolling by multiple rollers, the strip is gradually rolled up to form a circular tube blank with an opening gap. 3mm, and make both ends of the welding joint flush.1. If the gap is too large, the proximity effect will be reduced,

The finished product of seamless steel pipe precision steel pipe will have the problem of uneven thickness or eccentricity, but how does it happen? Many people don't understand. Today, let's talk about how the eccentricity of seamless steel pipes such as cold-drawn steel pipes, cold-rolled steel pip

Thick-walled steel pipes and thin-walled steel pipes have a big difference in the thickness of the pipe wall. The diameter of the steel pipe wall is greater than 0.02, we generally call it thick-walled steel pipe. Thick-walled steel pipes have a very wide range of applications. Due to their thicker
