As stated in GB/T 5099《Seamless Steel Gas Cylinder 》, seamless steel gas cylinders which designed and manufactured as per the standard were not suitable to be as additional large capacity cylinders on the transporting tools and machinery equipments. lf using for a long time, the serious hidden trouble will be occurred. in order to solve the above problems，our company researched and developed the large capacity seamless steel cylinders and also formed 《Storage Seamless Steel Pressure Vessel》which filled the blank in the industry. The max. working pressure is available up to 70 Mpa and the max. capacity is up to 800L. The product possesses the high safety, anti-fatigue, withstand high lord continues impulse and property stabilization etc. Which can beused widely in heavy mechanical industry，gas compressor，die-casting and forging，petroleum and military industries.

All the products accept the mandatory inspection and supervision from AQSIQ according to《The SafetyTechnology Supervision for Stationary Pressure Vessels》.
