Production process of high pressure rubber hose

1. Use a mixer to mix the inner layer glue, middle layer glue, and outer layer glue according to the formula; Use an extrude machine to extrude the inner tubing and wrap it around a soft or hard core coated with release agent (liquid ammonia freezing method can also be used without tubing Core) .

2. The rolling machine presses the middle layer rubber sheet, adds isolation agent to roll it up, and cuts it to the specified width according to the process requirements.
Medium to Multi Industrial Electrical Products.

Between the wire or copper plated steel wire rope, tie the beginning and end of the wrapped steel wire (some early winding machines require pre stressing and shaping of the copper plated steel wire).

4. Cover the extrude with an outer layer of adhesive again, and then wrap it with a lead or cloth vulcanization protective layer.

5. Sulfurization through a vulcanizing tank, a vulcanizing equipment or salt bath.

6. Finally, remove the sulfurization protective layer, extract the core, fasten the pipe joint, and conduct sampling and pressure testing.

In short, there are many equipment and types of raw materials used in the manufacturing of oil pipes, and the production process is complex. However, in recent years, the production process of hydraulic oil pipes mainly made of plastic or thermoplastic elastomer can be appropriately simplified. How
