(Summary description)1. Generally, carbon steel is a domestic seamless steel pipe provided according to the characteristics of the product organization. GB/T700-88A steel is selected (but the sulfur content must not exceed 0.050%, and the phosphorus content should not exceed 0.045%), and its mechanical properties should meet the The value required in the GB8162-87 table.
2. The domestic seamless pipeline should be determined as the standard hydraulic test according to the hydraulic test.
3. The technical performance inspection of imported seamless steel pipes shall comply with the relevant specifications stipulated in the contract.
2. Main use 2.1. Seamless steel pipes are universal. Ordinary seamless steel pipe is cold-rolled from ordinary carbon alloy structural steel, low alloy tool steel or alloy tool steel.
2.2. The products supplied according to the main purpose are divided into three categories: a, according to the composition and mechanical properties, b, according to the mechanical properties, c, according to the hydrostatic test. According to the seamless steel pipes provided by grades a and b, in order to better withstand the liquid pressure, a hydrostatic test must also be carried out.
Special seamless steel pipes include seamless steel pipes for heating furnaces, seamless steel pipes for geological environments, and seamless steel pipes for crude oil.
Third, type.
According to the difference in production, seamless steel pipes can be divided into hot-rolled pipes, cold-rolled pipes, cold-drawn pipes, extruded pipes, etc.
According to the appearance design, it is divided into round tube, special-shaped tube, etc. In addition to square tubes and rectangular square tubes, there are also stainless steel round tubes, semi-circular tubes, triangular tubes, hexagonal tubes, convex tubes, plum blossom tubes, etc.
According to the different raw materials, it is divided into ordinary carbon structural pipe, alloy structural steel structural pipe, high-quality carbon structural pipe, aluminum alloy structural pipe, stainless steel pipe, etc.
3.4. According to its unique main purpose, there are steam pipes, geological pipes, oil pipelines, etc.
