Total five working line make 3000pcs per day for oxygen gas cylinder, argon gas cylinder, helium gas cylinder, Nitrogen gas cylinder , Co2 gas cylinder, N2O gas cylinder..etc
China top one advanced heat treatment machine. And China top one internal polishing machine to make high purity gas cylinder with 99.999% oxygen gas, helium gas, N2O gas and argon gas etc.

   Advanced automatic spraying working line make the spraying at high top quality , no any bubble , without shrinkage and distoration .2500T pressure imported from Germany is able to to control the cylinder thickness tolerance under 1.5mm . From pressing to drawing, the whole system is completely automatic .Stamping machine imported from Japan with four stations working at the same time which ensures the cylinder's stamping is clear and even, which is top one in China .DSW seamless gas cylinder have nice appearance shoulders because we use shape-correction machine treatment make the cylinder shoulder most beautiful shape which other supplier can't be compared.Laboratory test standard ISO9809-3 and ISO9809-1, DOT-3AA, EN1964,GB5099 ..etc

100% Hydrostatic prssure test and leakage test to keep the quality. Introduced with American winding machines, vehicle-used CNG composite cylinder (hoop-wrapped with steel liner)is c consistent in appearance, stable in performance, safe and reliable.

Inspection and Testing Equipment
 
Transmission case running-in test:
The objective is to make the transmission case sliding bearing pass the run-in period so as to guarantee the steady operation of units.
 
Hydraulic pressure running-in test:
The objective is to perform running-in operation with load to the transmission case; in the meantime, a hydraulic test is performed to the pump head to inspect the pump head leakage and the quality of all weld joints.
 
Transmission case running-in test:
The objective of the delivery test of reciprocating pump unit is to completely assess the all performance indexes of the unit.
 
Centrifugal pump performance test:
The objective of liquid nitrogen cryogenic performance is to assess the all performance indexes of each centrifugalpump unit.
 
Immersed pump performance test:
The objective of liquid nitrogen cryogenic performance is to assess the all performance indexes of each immersed pump unit.
