Product manufacturing process:

Tube blank → Inspection (spectral detection, surface inspection, and dimensional inspection) → Sawing → Perforation → Thermal inspection → Pickling → Grinding inspection → Lubrication → Cold drawing → Lubrication → Cold-drawing (the addition of cycled processes such as heat treatment, pickling and cold drawing should be subject to the specific specifications) → Normalization or normalization + tempering → Performance test (mechanical property, impact property, hardness, flattening, flaring, and flanging) → Straightening → Tube cutting → Non-destructive testing (eddy current or ultrasonic) → Hydrostatic test → Product inspection → Immersion of anti-corrosive oil → Packaging → Warehousing
