Welded steel pipes can be classified into different types and types according to different classification methods. Welded steel pipes of different properties have different characteristics and characteristics in use and show different use values in use. Welded steel pipes can be classified into the

Simply put, the process of heating the steel pipe and controlling it to be above the recrystallization temperature for rolling is called hot rolling. The process of rolling below the recrystallization temperature, including normal temperature, is called cold rolling.Hot-rolled steel pipe has good pl

1. Spiral steel pipes shall not be stacked with acid, alkali, salt, cement, and other materials that are corrosive to steel in the warehouse. Different varieties of steel should be stacked separately to prevent confusion and contact corrosion;2. Large sections, rails, steel plates, large-diameter sp

1. Compared with 304 stainless steel pipe, the advantages of duplex stainless steel pipe are as follows:(1) The yield strength is more than double that of ordinary austenitic stainless steel, and it has sufficient plastic toughness required for forming. The wall thickness of storage tanks or pressur

The use and function of large diameter straight seam welded pipe1. The use of large-diameter straight seam welded pipes can be divided into oil well pipes (casing, oil pipes, drill pipes, etc.), line pipes, boiler pipes, mechanical structure pipes, hydraulic prop pipes, gas cylinder pipes, geologica
