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

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
2001 by the Chinese entrepreneurs assosiation awarded the "welding gas cylinder head of the national industry"
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.
