seamless Steel pipe It can be divided into hot rolled and cold rolled (pulled) seamless steel pipes. Hot rolled seamless steel pipes are divided into general steel pipes, low and medium pressure boiler steel pipes, high pressure boiler steel pipes, alloy steel pipes Stainless steel pipe , petroleum cracking pipe, geological steel pipe and other steel pipes. In addition to ordinary steel pipes, low and medium pressure boiler steel pipes, high pressure boiler steel pipes, alloy steel pipes, stainless steel pipes, petroleum cracking pipes and other steel pipes, cold-rolled (drawn) seamless steel pipes also include carbon thin-walled steel pipes, alloy thin-walled steel pipes, stainless thin-walled steel pipes and profiled steel pipes. hot-rolling Seamless pipe The outer diameter is generally more than 32mm, and the wall thickness is 2.5-75mm. The outer diameter of cold-rolled seamless steel pipe can reach 6mm, the wall thickness can reach 0.25mm, and the outer diameter of thin-walled pipe can reach 5mm, and the wall thickness is less than 0.25mm. Cold rolling has higher dimensional accuracy than hot rolling.
The company specializes in the production of bends, bend processing, stainless steel bends, carbon steel bends, bridges, airports, stadiums, etc pipe fitting Series products. You can press GB HG、GD、SH、ANSI、 AS ME, API 5L, FOCT, DIN, JIS and other standards. The products are exported to dozens of countries and regions in Southeast Asia, the Middle East, Europe, the Americas, Australia and South Africa. It enjoys a high reputation in the domestic and foreign markets. The company has nondestructive testing equipment, ultrasonic testing equipment, testing machines, impact testing machines, physical testing and chemical laboratories, forming a complete quality and safety testing system. It can fully meet various testing requirements proposed by customers. The company has always adhered to the quality of survival, continued to pursue good quality, and strive to build a brand. Anticorrosive composite steel pipe is suitable for the working environment. Compared with other metal pipe and plastic pipe composite pipes, it combines the characteristics of various pipes, including the strength of steel pipe, the corrosion resistance and wear resistance of plastic pipe, and the small fluid resistance. It is a green pipe with high safety and health strength and good bonding strength. In order to reduce pipeline transportation resistance, epoxy powder coating is used for internal corrosion prevention.
It can be divided into general welded pipe, galvanized welded pipe, oxygen blown welded pipe, wire casing, metric welded pipe, idler pipe, deep well pump pipe, automobile pipe, transformer pipe, electric welding thin-walled pipe, electric welding profiled pipe and spiral welded pipe.
