3.1, according to the institution's domestic supply seamless performance, common carbon steel according to the CPI steel GB / T700-88 (but must ensure that the sulfur content of no more than 0.050% and phosphorus content of no more than 0.045%), mechanical performance should be consistent with the value stipulated in GB8162-87 table 3.2, according to the domestic supply of seamless pipe hydrostatic testing hydrostatic test must ensure that standards required by 3.3, import seamless physical performance test according to the relevant provisions of the contract standards. 2, uses 2.1, seamless pipe is so widely used general-purpose by the ordinary carbon steel seamless pipe, most low-alloy structural steel or alloy structural steel rolling, yield, mainly used for pipes conveying fluids or Structural parts 2.2, divided into three categories according to different uses supply: a, according to the chemical composition and mechanical properties supply; b, according to the mechanical properties of supply; c, according to the hydrostatic test supply by a, b class supply pipe, such as for. withstand the liquid pressure, but also pressure test. 2.3, seamless special-purpose variety. 3 boiler seamless pipe, seamless pipe and petroleum geology seamless pipe, a broad 3.1, seamless press Different production methods can be divided into hot-rolled pipes, cold-rolled, cold-drawn tubes, squeeze tubes. 3.2, according to shape classification round tube, shaped tube of the points. In addition to shaped tube square tube and rectangular tube, there oval tube, half pipe, triangular tubes, hexagonal tubes, convex-shaped tube, plum-shaped tubes. 3.3, according to the different materials, divided into ordinary carbon structural pipe, low alloy structural pipe, quality carbon structure tube, alloy structure pipe, stainless steel pipe. 3.4, according to the special zoning, boiler tubes, geological tubes, oil pipe. seamless pipe
4, specifications and appearance quality
