Methods to choose an LPG deliver hose
NBR oil hose is a common material in oil industry. But steel wire weaving is too tight, too loose, uneven thickness of hose wall, too few steel wire layers, and poor air tightness of outer rubber layer will cause steel wire corrosion. This will lead to a decrease in the bearing capacity of the hose, and finally burst at the thin part of the hose wall.
The quality of NBR hose not only concerns the normal operation, but also concerns security and pollution problem. Thus a high quality nitrile hose is really important. But the quality of such hose is quite different on the market. Then how to distinguish the quality of nitrile oil hose?
Everflex offers you 6 tips
1. The deformation of the hose after pressurization (elongation, shortening or bending deformation) is large;
2. The air tightness of the outer rubber layer is poor, which will cause steel wire corrosion;
3. The thickness of the hose wall is uneven;
4. The steel wire weaving is too tight, too loose, or the number of steel wire layers is too few;
5. The inner rubber layer has poor sealing, which makes it easy for high-pressure oil to enter the steel wire layer, reducing the service life of the hose;
6. The adhesion between the rubber layer and the steel wire layer is relatively poor, and the strength is insufficient.
With above methods, you can distinguish what is a low quality rubber oil hose. But the most simple way to choose a high quality hose is to find a reliable hose supplier. Because only a reliable supplier can guarantee the hose quality. Here I recommend you Everflex. It has full series of PVC hose and rubber hose with high quality and cost performance.
