Sheathed high-pressure oil pipes refer to pipes used to transport liquid media in high-pressure hydraulic systems. It not only has excellent properties such as pressure resistance, wear resistance and corrosion resistance, but also uses special sheath material for protection to improve its service life and safety.

In general, high-pressure oil pipes with sheaths can be divided into the following categories:

Rubber-sheathed high-pressure oil pipe: This high-pressure oil pipe is generally composed of two parts: a rubber pipe and a metal pipe. The rubber tube is responsible for conveying the liquid medium, and the metal tube plays the role of support and reinforcement. The surface of the metal pipe is covered with a layer of rubber sheath, which can prevent external objects from damaging or corroding the high-pressure oil pipe.

Polyurethane sheathed high-pressure oil pipe: This high-pressure oil pipe is generally made of polyurethane material. The polyurethane sheath has good impact resistance and wear resistance, and the material is light, which will not increase the weight of the high-pressure oil pipe. In addition, the polyurethane sheath can also effectively prevent the high temperature and low temperature environment from affecting the high pressure oil pipe.

Nylon-sheathed high-pressure oil hose: This high-pressure oil hose is generally made of nylon material. The nylon sheath has good wear resistance and toughness, and the material is light, which will not increase the weight of the high-pressure oil pipe. In addition, the nylon sheath can also effectively prevent damage to the high-pressure oil pipe by external objects.
It should be noted that although the sheathed high-pressure oil pipe has a good protective effect, it still needs to follow the relevant safety operation regulations during use. For example, during installation, it is necessary to ensure that the connection is firm and reliable, and there will be no leakage due to excessive pressure; during use, the state of the high-pressure oil pipe should be checked regularly, and problems should be found and repaired in time to ensure the long-term stable operation of the high-pressure hydraulic system .
