High - Pressure Wire Braided Hose Production Process
- Oct 25, 2017 -

1. Mix the inner layer, the middle layer and the outer layer with the mixer according to the formula; extrude the inner oil pipe with the extruder and cover the soft core or hard core coated with the release agent (liquid nitrogen refrigeration method can not use the tube core).

2. Calender press into medium glue sheet, add isolation agent winding, and according to the process requirements cut into the specified width.

3, with inner tube core tubing in a winding machine or knitting machine winding copper wire or copper wire rope winding machine, at the same time in the middle or knitting machine will glue sheet synchronization winding in each of the two layers of copper wire or copper wire rope, wire winding start and end binding (some early winding machine in advance the copper wire for prestressed setting).

4, again on the extruder to cover the upper and outer layer of glue, and then wrapped lead or cloth vulcanized protective layer.

5. Vulcanization by vulcanizing tank or salt bath.

6, finally remove the sulfide protective layer, pumped out of the tube core, pressing pipe joint, pressure sampling inspection. In short, the production of high pressure tubing using many equipment, raw materials and many kinds of complex production process. But in recent years, plastic or thermoplastic elastomer as the main raw material for the production of hydraulic tubing can be appropriately simplified, but the raw material price is high, still mainly rubber raw materials.
