 1、 with the mixer according to the formula mixing out of the inner layer of rubber, the middle layer of rubber and outer layer of rubber; with the extruder to extrude the inner layer of tubing, wrapped in the coated with a release agent on the soft core or hard core (liquid nitrogen freezing method can be used without the tube core).
 2、Calender press into the middle layer of rubber sheet, plus isolation agent rolled and cut into the required width according to the process requirements.
 3、 will contain the core inner layer of oil pipe in the winding machine or braiding machine winding on copper-plated steel wire or copper-plated steel wire rope, at the same time in the winding machine or braiding machine will be synchronized with the middle layer of rubber sheet winding in each two layers of copper-plated steel wire or copper-plated steel wire rope between the winding steel wire at the beginning and the end of the binding (some of the early winding machine need to be in advance of the copper-plated steel wire for the pre-stressing and shaping treatment).
 4、Wrap the outer layer of rubber on the extruder again, and then wrap the lead or cloth vulcanization protection layer.
 5、through the vulcanization tank or salt bath vulcanization.
 6、after removing the vulcanized protective layer, pull out the core, buckling on the pipe joints, sampling pressure test. In short, the manufacture of high-pressure oil pipe using a variety of equipment, raw materials, complex production process. However, in recent years to plastic or thermoplastic elastomer as the main raw material of hydraulic hose production process can be appropriately simplified, but the high price of raw materials, still mainly rubber raw materials.

Industrial hose, rubber hose how to identify good and bad?

Rubber hose is divided into two kinds of high-pressure hose and low-pressure hose, high-pressure hose is generally composed of four parts: outer rubber layer, steel wire reinforcement layer, middle rubber layer and inner rubber layer. The inner rubber layer of the hose is in direct contact with the hydraulic oil, generally made of synthetic rubber. The bearing capacity of the hose depends on the strengthening layer, the layer is the skeleton of the hose, usually made of steel wire braid or winding. Most of the high-pressure steel wire braid for the skeleton, high-pressure, high-pressure steel wire winding skeleton. The outer rubber layer of the hose is generally made of wear-resistant, corrosion-resistant rubber to ensure that the reinforcing layer is not subject to mechanical damage, chemical corrosion, moisture rust, low-pressure hose to braided cotton, hemp wire instead of braided steel wire, generally used for low-pressure oil return pipeline.

What are the applications of high pressure cleaning hose?

Various specifications of water and sewage pipelines, high-pressure cleaning tube industrial water pipelines, industrial and industrial and mining enterprises and residential sewage pipes, defeat, rainwater pipes, gas pipes, municipal pipelines, flue, oil pipelines and two-phase flow pipeline clogging;
