Structure And Materials Of High-pressure Rubber Hose

High-pressure rubber hoses are flexible pipes made primarily of synthetic rubber, employing a multi-layered composite structure design to reliably transport high-pressure fluid media. The following are their core elements:

A typical structure includes:

Inner Rubber Layer: In direct contact with the transported medium, made of oil-resistant and corrosion-resistant synthetic rubber (such as nitrile rubber (NBR) or ethylene propylene diene monomer (EPDM) rubber), ensuring sealing and media compatibility.

Reinforcing Layer: Formed by braiding or winding high-strength steel wire to withstand internal pressure (single-layer braiding withstands 20-40 MPa, multi-layer winding can reach over 60 MPa).

Outer Rubber Layer: A wear-resistant and anti-aging protective layer (commonly neoprene rubber), resisting damage from the external environment.

Special designs may incorporate conductive steel wire (for anti-static purposes) or translucent materials (for easy fluid observation).
