Gas pressure hose is widely used in various industries, especially in the energy sector, is the higher cost of gas equipment products.

Production process:
1, with a mixing kneader according to the formula of the inner plastic, rubber and plastic outer middle; with extruder inner tubing, coated with a release agent coated on a soft or hard-core core (liquid nitrogen freezing can not die)
2, middle rubber calender pressed into thin slices, add press release agent rewinding process requirements specified width cut
3, the inner tubing with tube core winding machine or knitting machine in the wound on the copper wire or copper wire, while winding machine or knitting machine will synchronize wrapped around the middle of each plastic sheet copper wire or copper wire, two inter-, beginning and end of the winding wire lashing (some early winding machine will be pre-processed copper wire for prestressed stereotypes)
4, again in the extruder was coated on the outer layer of glue, and then wrapped a protective layer of lead sulfide or cloth
5, through the autoclave or salt bath vulcanization
6, and finally remove the sulfide layer of protection out of the die, to withhold fittings, sampling pressure test.
