1. Corrosion test: The supplied industrial corrosion-resistant steel pipe should be tested for corrosion resistance in accordance with mutually agreed standards or corrosion methods, and shall not have a tendency to intergranular corrosion.

2. Process performance test: flattening test, tensile test, impact test, flaring test, hardness test, metallographic test, bending test and nondestructive test (including eddy current test, x-ray test and ultrasonic test).

3. Chemical analysis: chemical analysis of the chemical composition of the material, chemical composition in line with the standard.

4. Air pressure and water pressure test for pressure-resistant pipes, should be carried out one by one water pressure test. The pressure value shall not be less than 5 seconds, and shall not leak. Conventional supply hydraulic test should be 2.45 MPa. Pneumatic test is pressure = 0.5 MPa

Therefore, the performance of stainless steel seamless pipe can be said to be very outstanding, so it is a good choice for people and has been widely used.
