Methods to choose an LPG deliver hose
First, under the current condition of excessive cost, synthetic resin pipes have indeed improved quality and reduced costs. From the perspective of the hose’s oil resistance and aging resistance, ultra high pressure resin pipes use polymer materials such as nylon and polyurethane elastomers. Therefore, the service life is greatly improved.
Secondly, the high-pressure rubber hose body is soft and has a small bending radius. The internal reinforcement layer and rubber of the pipe body are well bonded. However, the bonding layer and reinforcement layer of the new ultra-high pressure resin pipe are basically not bonded. Even if the manufacturer uses adhesives and other materials as compensation. However, this is a defect. First, the current hose crimping equipment is not accurate enough. Secondly, the quality of the pipe joints is not standardized.
In theory, the inner rubber layer of the ultra-high pressure resin pipe is absolutely oil-resistant. There is basically no situation where the rubber layer is eroded by oil. Therefore, after precise crimping, the hose should not leak oil or fall off. This topic has been solved after many manufacturers adopted endoscopic measurement technology. In addition, the bending radius of the ultra-high pressure resin pipe is generally larger than that of the traditional high pressure rubber pipe. This also affects the design and construction.
Third, it is due to the high hardness of the material used in the inner rubber layer of the ultra high pressure resin pipe. This has led to many manufacturers having many inadaptabilities when crimping hose joints, and a large number of products have oil leakage and other phenomena.
