1. The cylinder should be design manufactured, inspected and accepted according to GB5100.Weld Steel Gas Cylinders and Supervision&Inspection Rules for Cylinders'safety.
2. The longitudinal and circumferential seams must be welded by electric-arc welding, and the welds must be made by a machine process. The tensile strengh of joints must be not less than the tensile strength of minmum by parent material standard.
3. The longitudinal and circumferential welds must be examined by ≥20% X-ray radiography and evaluated according to JB4730 Nondestructive Testing of Pressure Vessels. Grade is qualified.
4. The cylinder must be subjected to heat treatment to relieve stress entirely after all welding work has been competed.
5. The cylinder must withstand a hydrostatic test to 45kgf/cm according to GB/T9251 Methord for Hydraulic Test of Gas Cylinders after heat treatment. Dry the internal surface after testing.
6. The cylinder must withstand a pneumatic test to 30kgf/cm according to GB12137 Methord for Pneumatic Testing of Gas Cylinders.
7. Internal surface should be subjected to rust cleaning before assembly and external surface should be subjected to shot blasting after assembly. The cylinder should be coated with anticrrosion primer(＞20um) and yellow finish paint(＞40um).
8. Thread seal should be winded with PTEE.
9. 16MnR can be used as material of ends and shell. See mechanical properties and chemical composition in table of Body Material.
