JCOE Pipe
JCOE is a type of straight seam double-sided submerged arc welded pipe. LSAW steel pipe can be divided into high-frequency LSAW steel pipe and submerged arc welded LSAW JCOE steel pipe based on the production process. Submerged arc welded straight seam steel pipes are divided into UOE, RBE, JCOE,...Read more -
Steel pipe heat treatment
Heat treatment is a process to improve the performance of metal materials and their products. According to different purposes, the material and its workpieces are heated to a suitable temperature, kept warm, and then cool by different methods to change their internal organization to obtain the re...Read more -
Differences between ERW and EFW
ERW stands for Electric Resistance Welding. The welding method for ERW pipe and submerged arc welded pipe is significantly different. ERW uses a pressure welding method without filler metal, resulting in a weld that is not filled with other components. The high-frequency current skin effect and p...Read more -
17 major avoidance principles in the steel pipeline construction
1. The small steel tube makes the big tube: the small tube is easy to bend and the cost is low. 2. Branch pipes to main steel pipes: branch pipes are generally smaller in diameter. See Article 1 for the reasons for avoidance. Also, the scope and importance of branch steel pipes are not as importa...Read more -
The Difference Between Hot Rolled Steel Pipe And Cold Rolled Steel Pipe and Welded Steel Pipe
Hot rolled steel pipes are a type of steel pipe product that offers unique advantages. By refining the grain structure of the ingot, it can destroy the casting organization and eliminate microstructure defects, resulting in improved mechanical properties. Additionally, the market offers a variety...Read more -
Embroidery removal technology of submerged arc steel pipe
1. Cleaning Use solvents and emulsions to clean the surface of the steel to remove oil, grease, dust, smoothing agent and similar organic matter, but it cannot remove the rust, oxide scale, welding flux, etc. on the surface of the steel, so it is only used as an auxiliary in anti-corrosion homewo...Read more
