Seamless Steel Tube Capillary Extension Process
When the seamless steel tube is tempered at 650 °C, its impact toughness value is the lowest, that is, the temper brittle zone, so it is not suitable to temper in this temperature range. It should be ...
What Are The Heat Treatment Processes For Thick-walled Seamless Pipes?
The surface heat treatment technology of the 45th thick-walled seamless steel pipe is constantly being innovated, and the current technology has been developed more and more sophisticated. Let's take ...
Seamless Steel Pipe Is The Best Choice For Sewer Pipes
In urban construction, the role of seamless steel pipes is also very large. This kind of pipeline material is used as a transportation pipeline for groundwater in urban construction, and it is often b...
The Difference Between Welded Pipe And Seamless Steel Pipe
Welded steel pipe: A steel pipe produced by welding a steel plate or a strip of steel into a cylindrical shape. According to the welding method, it can be pided into arc welded pipe, high frequency or...
Why Is Cold-drawn Seamless Steel Pipe Heat Treated
During the heating and cooling process of the cold drawn seamless steel pipe, due to the inconsistency between the cooling rate and the time of the surface layer and the core, a temperature difference...
Cold Drawn Seamless Steel Pipe Production Needs Attention To Control Points
1. Capillary tube
The wall thickness of the capillary tube should be uniform, and the surface defects on the inner and outer surfaces should be small; the outer surface polishing and inner hole defect...
