1、chemical analysis:To make a chemical analysis of the chemical composition of material, the chemical composition in line with standard requirements.
2.Pneumatic test、Hydrostatic test： To design a Hydrostatic test of the pressure tube, the prescribed pressure value is maintained not less than 5 seconds,, non-disclosure, conventional supply hydraulic pressure test of 2.45MPa. Air pressure test for P = 0.5MPAa.
3, corrosion test: According to the standard or bipartite agreement, design corrosion resistance test of the corrosion-resistant steel for industrial, without tendency to intergranular corrosion.
4, process performance test: flattening test. Tensile test. Impact tests. Flare test. Hardness test. Metallographic testing. Bending
Test. Nondestructive testing (including eddy current testing. X-ray flaw detection and ultrasonic testing).
