Stainless steel seamless pipe is economical cross-section steel, an important product in the iron and steel industry, and can be widely used in life decoration and industry.
Stainless steel pipes can be divided into Cr series (400 series), Cr-Ni series (300 series), Cr-Mn-Ni (200 series) and precipitation hardening series (600 series) according to their composition.
According to the production method, it is divided into two categories: seamless pipes and welded pipes. Seamless steel pipes can be divided into hot-rolled pipes, cold-rolled pipes, cold-drawn pipes and extruded pipes. Cold-drawn and cold-rolled are the secondary processing of steel pipes. Welded pipes are divided into straight seam welded pipes and spiral welded pipes.
According to the cross-sectional shape, it can be divided into round tubes and special-shaped tubes. Special-shaped tubes include rectangular tubes, rhombus tubes, oval tubes, hexagonal tubes, octagonal tubes, and various asymmetrical cross-section tubes. Special-shaped tubes are widely used in various structural parts, tools and mechanical parts. Compared with round pipes, special-shaped pipes generally have larger moments of inertia and section modulus and have greater resistance to bending and torsion, which can greatly reduce structural weight and save steel.
According to the state of the tube end, it can be divided into smooth tube and wire tube. Threaded pipes can be divided into ordinary threaded pipes and special threaded pipes. For some special pipes, in order to compensate for the influence of the thread on the strength of the pipe end, the pipe end is usually thickened before the threading.
According to the purpose, it can be divided into oil well pipes, line pipes, boiler pipes, mechanical structure pipes, hydraulic prop pipes, gas cylinder pipes, geological pipes, chemical pipes and marine pipes.
