Property
1.1 According to the supplying of mechanism performances about the domestic seamless steel pipe, common carbon steel as per the A class of GB/T700-88( content S ≤0.050% and P≤0.045% should be guaranteed), and mechanical property should conform to GB8162-87
1.2 Hydrostatic test must based on relative standard.
1.3 The physical properties in testing of imported
SMLS steel pipe based on relative standard.
Application
2.1 The application is quite widely. General usage of smls steel pipe is common carbon structural steel pipe, low alloy structural steel pipe or alloy structural steel pipe. And output is the largest quantity. We usually use them in transmission fluid pipe or structure of the parts.
2.2 Three supplying style based on different usage: a. Chemical compsition and mechanical capacity
b. Mechanical capacity c. Hydrostatic test. According to a, b supply steel pipe, such as used for liquid under pressure, also must carry on the hydraulic pressure test.
2.3 Special use of seamless steel tube such as boiler seamless steel pipe, geological seamless tube and oil seamless tube, etc.
