Carbon steel pipe foaming technology is a mixture of polyurethane black and white materials in proportion, which undergoes chemical expansion and is filled between the steel pipe and the outer protective tube of polyurethane foam insulation pipe. The one-step foaming process is currently widely used. The one-step foaming process involves adding polyether or polyester polyols […]
SMLS steel pipe is the abbreviation for Seamless steel pipe, which is a type of steel pipe without welds. It is made from continuous steel plates or strips processed through processes such as rolling, hot rolling, and cold drawing.Advantages of SMLS steel pipe:
During acid pickling of alloy steel pipes, hydrogen not only has a stripping effect on the oxide scale, but also diffuses into the interior of the billet matrix and accumulates at impurities or pores, leading to an increase in internal stress, reducing the plasticity of the steel, and increasing its brittleness. This effect is called
This material is prone to three quality problems in production: cracks, double skin, and slag inclusion. Crack generation and centrifugal pouring process, unreasonable pouring system; The double skin is related to the pouring temperature and pouring speed; Slag inclusion is related to the content of metal chemical elements and slag removal treatment.The prevention and control
