How to choose ultra-high pressure hose?

Wire spiral resin ultra-high pressure hydraulic hose hydraulic equipment special hose manufacturers

The reinforcement layer of the ultra-high pressure hydraulic hose is a specially treated wire winding layer, the inner adhesive layer is polyformaldehyde (POM) or polyamide (PA), and the outer adhesive layer is the corresponding polyamide (PA) or polyurethane (PUR). The hose has low fluid resistance, small volume expansion, good chemical corrosion resistance, light weight, small outer diameter, and a single length of up to 1200m. Choice of carbon steel or stainless steel for hose fittings.

Product composition:

Lining: polyamide (PA) or polyformaldehyde (POM)

Reinforcement layer: wire wound

Outer coating: polyurethane

Product features:

High pressure resistance, oil resistance, acid and alkali resistance, aging resistance, wear resistance, beautiful appearance, smooth inner wall, low fluid resistance, long service life

Temperature range: -40℃-120℃

Ultra-high pressure hoses have the following four characteristics:

1. Four-layer design, of which two layers are wire braided layer, plastic clad nylon hose.

2. Used in strict places, 4 times the coefficient.

3. Light weight, small size, large bending radius.

4. Small volume expansion under pressure.

High pressure hydraulic hose selection precautions:

When selecting hoses, the appropriate hoses, fittings and hose assemblies should be selected according to the specific application.

Factors to consider are: hose type, hose size, hose length, system working pressure, system fluid and use of the environment, please refer to the product standard for selection.

There are a variety of connections for the buckle hose assembly, and different connections should be selected according to different types of hoses.

Note: There are two types of hose that need stripping and no stripping. The joint is also different, and the groove of the joint sleeve that needs to be stripped of the outer adhesive is not too sharp, otherwise it will damage the reinforcement layer of the hose. Proper clamping of the joint is essential to the proper operation of the hose assembly.

There are many types of joints, and the appropriate joints should be selected, and the sleeve design should be standard and reasonable. Sharp grooves and irregular dimensions can break the wire reinforcement. When clamping the joint, the clamping amount should be determined according to the inner and outer diameter of the hose.
