The experiment makes the welding part flattening deformationunder to check its strength.If the samples withstand deformationwithout cracks , then qualified.
For industrial corrosion resistant stainless steel tube, do X-rayflaw detection test ,to make sure dense pore-free ,guarantee nomicro crack ect.
Doing chemical analysis for the welding pipe raw material andadding material , to male sure it comply with standard .
lndustrial corrosion resistant stainless steel tube, with thecorrosion method of standard or mutual agreement, after pipeand weld intergranular corrosion inspection, shall not have intergranular corrosion inclination.
After flanging of test specimen, whether in the welding part or inthe base metal no cracks.
Doing a series of hydraulic pressure test, under certain pressureand stipulated time, no leakage and no leakage for qualified.
