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