Production Process of Hot-rolled Seamless Steel Pipe
Hot-rolled seamless steel pipe: Hot rolling is relative to cold rolling, cold rolling is rolling below the recrystallization temperature, and hot rolling is rolling above the recrystallization tempera...
Manufacturing Process of Stainless Steel Seamless Pipe
The corrosion resistance of stainless steel seamless pipes depends on the alloying elements contained in the steel. Chromium is the basic element for the corrosion resistance of stainless steel. When ...
Welded Vs. Seamless Stainless Steel Pipe
Stainless steel pipes can be pided into stainless steel welded pipes and stainless steel seamless pipes. Many people do not know the difference between them. How to choose? The following stainless ste...
Design and Construction of Cathodic Protection Station for Oil Well Casing
The most important parameter in the cathodic protection of oil well casing is the penetration depth of the protection current and its magnitude, which depend on the geological structure and the resist...
Cathodic Protection for Well Casings
With the rapid development of the petroleum industry, serious corrosion of oil well casings, buried pipelines, and storage tank bottom plates in oil fields, especially oil well casings, has severely a...
The Basic Process of High-frequency Welded Pipe Sizing
The sizing of high-frequency straight seam welded pipes (ERW welded pipe) refers to the rolling of welded pipes after welding by rollers of a specific pass, and the round or special-shaped pipes of ir...
Multi-wire Submerged Arc Welding Process of Longitudinally Welded Pipe
Because the multi-wire submerged arc welding of longitudinally welded pipes has the characteristics of large undercooling and fast welding speed, the equilibrium state is basically eliminated. If the ...
The Significance of Studying the Heat-Affected Zone of Welded Pipe Welding
Welding heat-affected zone（HAZ) is different from welding seam. Welding seam guarantees performance requirements through chemical composition adjustment, redistribution and proper welding process, whi...
Comparison of Straight Seam Steel Pipe and Spiral Steel Pipe
The production process of straight seam steel pipes is relatively simple, and the main content of the production process is high-frequency welded straight seam steel pipes (ERW) and submerged arc weld...
Difference between Carbon Steel Seamless Pipe and Stainless Steel Seamless Pipe
The difference between carbon steel seamless pipe and stainless steel seamless pipe mainly refers to the difference in design rules between stainless steel and carbon steel, which means that the desig...
