The following is a comprehensive technical analysis and application guide for high-pressure rubber hoses:
I. Core Structure and Types
Steel wire reinforced type
It is composed of an inner rubber layer, a steel wire braided/wound layer, and an outer rubber layer. The working pressure can reach 70-100 mpa, and it is suitable for high-pressure scenarios such as mine hydraulic supports and oilfield exploitation .
There are two types: steel wire braiding (1-3 layers) and winding (2-6 layers). The latter has a higher pressure resistance but a larger bending radius .
Aramid fiber reinforced type
Using aramid fibers instead of steel wires offers advantages such as lightweight, corrosion resistance, and fatigue resistance, and is suitable for special environments like automotive fuel systems and submarine cables .
Ii. Key Points for Selection and Installation
Medium compatibility
For the transportation of petroleum-based liquids, oil-resistant synthetic rubber inner layer (such as NBR) should be selected; for water-based liquids, EPDM material is required.
Joint seal
Conical surface seals or flange joints are preferred. During installation, the compression amount of the O-ring should be controlled (0.35-0.65mm) .
Protective measures
Avoid contact with sharp parts. In high-temperature environments, heat insulation boards should be installed .
Note : Extreme working conditions (such as ultra-high pressure or vacuum) require customized design and strictly follow the burst pressure test data provided by the manufacturer.
