（5）Step（4）Steel cylinder after processing rinsed in shoulder inner face processing, screw thread process, bottle, obtains high pressure gas
Steel cylinder.
Described two-phase stainless steel seamless steel tube prepares the method for high pressure gas cylinder, step（1）Described two phase stainless steel
A diameter of 159 ~ 350 mm of seamless steel pipe, thickness is 3 ~ 8mm；The length that cutting obtains blank is 800 ~ 1800mm.
Described two-phase stainless steel seamless steel tube prepares the method for high pressure gas cylinder, step（3）Bottom, milling are received in described heating
Bottom of bottle, heating is closed up, bottleneck drilling concrete operation step is：
A. one end of cleaved two-phase stainless steel seamless steel tube blank is placed in heating furnace, heated length is from end
Mouth starts length at 230 ~ 300mm, and heating-up temperature is 1150 ~ 1350 DEG C, and the heat time is 5 ~ 10min；
B. the blank after heating is subjected to spinning immediately, spinning main shaft rotating speed is 600 ~ 800r/s, once completes to receive
Bottom, the receipts bottom time is 80 ~ 120s；Initial temperature when receiving bottom is 1100 ~ 1200 DEG C, is mended in spinning process with gas nozzle
Air cooling is molded after heat, spinning, last milling bottom of bottle, is repaiied and is cut；
C. repeat step a, b carries out hot spinning to the other end of blank, and heating is closed up；
D. the heating closing in described in step c treats that bottle is cooled to room temperature after completing, and is drilled on bottleneck.
Described two-phase stainless steel seamless steel tube prepares the method for high pressure gas cylinder, the instrument used in spinning described in step b
Device is roller type spinning machine.
The method that described two-phase stainless steel seamless steel tube prepares high pressure gas cylinder, the spinning machine described in step b is revolved
When turning to receive bottom, spinning main shaft rotation is in 100 ° between mould rotation centerline and blank rotation centerline, during mould rotates along mould
Heart line rotates 100 °.
The method that described two-phase stainless steel seamless steel tube prepares high pressure gas cylinder, the combustion gas described in step b is acetylene, day
Right gas or oxygen.
Steel pipe heating receive bottom during, for make up because temperature reduce caused by steel pipe plasticity compromises, with natural gas,
Acetylene or oxygen jet carry out concurrent heating；The rotating speed of spinning main shaft is 600 ~ 800r/s, and the time used in bottom of receiving is 80 ~ 120s.
Described two-phase stainless steel seamless steel tube prepares the method for high pressure gas cylinder, step（4）Described solution heat treatment
