What is Stainless Steel Seamless Pipe? Its Features and Applications
Generally, seamless steel pipes have low precision: uneven wall thickness, low brightness of the inner and outer surfaces of the pipe, high cost of sizing, and pitting and black spots on the inner and outer surfaces that are difficult to remove; its detection and Shaping must be processed offline. Therefore, it reflects its superiority in terms of high pressure, high strength, and mechanical structural materials.

Product Features
1. Chemical analysis: Conduct chemical analysis on the chemical composition of the material, and the chemical composition complies with the standards.
2. Air pressure and hydraulic pressure test: The pressure-resistant pipes are tested one by one. The specified pressure value is not maintained for no less than 5 seconds and there is no leakage. The conventional supply hydraulic pressure test is 2.45MPa. The air pressure pressure test is P =0.5MPAa.
3. Corrosion test: All industrial corrosion-resistant steel pipes supplied are tested for corrosion resistance in accordance with standards or corrosion methods agreed upon by both parties. There must be no intergranular corrosion tendency.
4. Process performance inspection: flattening test, tensile test, impact test, expansion test, hardness test, metallographic test, bending test, non-destructive testing (including eddy current testing, X-ray testing and ultrasonic testing).
5. Theoretical weight:Cr-Ni austenitic stainless steel W=0.02491S(D-S)Cr-Ni-Mo austenitic stainless steel (kg/m)S-wall thickness (mm)D-Outer diameter (mm)
