Standards of hydraulic hose fittings
The raw material of the composite hose is polyester PU (higher abrasion resistance compared to normal PU). As we all know, PU is a wear resistant in plastic raw materials. Composite hose series products develops with new materials. After long-term use, you will find that PU steel wire hose from new materials are better than recycled materials in service life.
Composite hose adopts spiral steel wire. Thus it’s light weight, easy to carry and flexible. Because of the PU material, it resists high and low temp as well as aging. Besides, the corrosion resistance is also good. BY grounding the spiral steel wire, it can conduct the static. Thus it’s more safe to transfer flammable and explosive things.
Composite hose is wear resistant and commonly serve in vacuum apps. It to deliver chips, dust, leaves, powder, steam and other mediums. While it’s ideal for wood work, workshop and industrial dirt remove. The wall thickness of the Pu steel wire hose is 0.4mm to 2.0mm. 0.4mm PU duct hose is flexible and very suitable for the dynamic work condition.
Composite hose and PVC steel wire hose are two common hoses. However, the specific properties of these two composite hoses are quite different. Here are three points:
1. The work temp. Generally, PVC steel wire hose can work at max 65°C. While the PU steel wire hose can reach 125°C.
2. The wear resistance. PU steel wire hose is more wear-resistant, 5 times that of PVC hose. Therefore, when absorb materials with large particles and high wear, the service life of the PVC hose is very short. While it’s long of the PU hose.
3. If the wall thickness and the wire space are the same, the composite hose will be softer and the PVC will be harder.
