100% new high quality seamless steel pipe from China top three steel factory.
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
