High pressure rubber is a kind of rubber hose with high cost performance

The high-pressure rubber hose is used to mix the inner rubber, the middle rubber and the outer rubber of the high-pressure rubber hose according to the formula; Extrude the inner oil tube with an extruder, and the high-pressure rubber tube is wrapped on the soft core or hard core coated with the release agent (the liquid nitrogen freezing method can also be used without the tube core);
The high-pressure rubber hose is coated with outer rubber on the extruder again, and then wrapped with lead or cloth vulcanization protective layer; The high-pressure rubber hose is vulcanized through vulcanization tank or salt bath; Finally, remove the vulcanized protective layer, pull out the pipe core, buckle the upper pipe joint, and conduct sampling and pressure inspection.
In short, there are many equipment, many kinds of raw materials and complex production process for manufacturing high-pressure hose. However, in recent years, the production process of hydraulic tubing with plastic or thermoplastic elastomer as the main raw material can be appropriately simplified, but the raw material is still rubber raw material with high price
