Our company is China's largest in low pressure welding gas cylinder manufacturer, is the national standard
GN5100-2011 standard responsible for drafting unit,welding gas cylinder production and sales of the national
market more than 45%, and 90% for export welding gas cylinder design, manufacturing. Five types of welding
gas cylinder has nine times by the national,provincial an ministry as high quality products, the products are ex-
ported to the west Asia, the middle east,western Europe,southeast Asia,Japan,Korea,Germany, the United stat-es and other countries and regions, for the domestic welding gas cylinder's biggest export enterprise. In october
honorary title.
SPECIFICATION:
1 The cylinder should be manufactured,inspected and accepted according to GB5100 welded /steel/gas cylinder
2 The longitdinal and circumferential seams must be welded automaticly by electric-arc welding ,the tensile strengthof joints must be not less than minimum value required.
3 The longitdinal and circumferential welds welds must be examined by ≥20% X-ray radiagraphy.
4 The cylinder must be subjected to heat treatment to relieve stress entirely after all welding
operation have been completed.
5 The cylinder must withstand a hydrostatic test to 45bar without leakage and deform after
heat treatment. Dry the internal surface after testing.
6 The cylinder must withstand a pneumatic test according to GB12137 .
7 Tread seal should be winded with PTFE.
8 16MnR can be used as material of ends and shell.
