In theory, the rubber layer in the high-pressure resin tube is absolutely oil-resistant, and there is basically no rubber layer eroded by oil. Therefore, after accurate crimping, the hose should not leak oil or lose its head. In addition, the bending radius of the ultra-high pressure resin pipe is generally larger than that of the traditional high pressure rubber pipe in the past, which also affects the design and construction. Since the 1990s, a new type of high-pressure hose product, a high-pressure synthetic resin tube, has surfaced. This topic is firstly caused by the insufficient accuracy of the current hose crimping equipment, and secondly, the quality of the pipe joints is not standardized. However, new topics that are constantly exposed in the application of ultra-high pressure resin pipes are indeed worthy of research by production units. This product has been widely used in developed countries such as the United States and Japan; the digitization of domestic high-pressure rubber hoses has also become the guiding force for product upgrades in the industry.

Secondly, the high-pressure rubber hose is soft, the bending radius is small, and the reinforcing layer in the tube is well bonded to the rubber; the rubber layer and the reinforcing layer of the new ultra-high-pressure resin tube are basically non-stick, even if the manufacturer uses materials such as adhesives as compensation; but this is a defect.

Third, due to the high hardness of the rubber layer of the high-pressure resin pipe, many application manufacturers caused a lot of incompatibility when the hose joint was crimped, and the product leaked a lot of oil.

Ultra-high pressure resin hose refers to a high-pressure hose made of a hose extruded from plastic material as the inner core and braided or wound with high-strength industrial fibers or steel wires. The pipe body is generally divided into three layers: the inner hose layer, the skeleton reinforcement layer and the outer rubber layer. Fiber (steel wire) braided high-pressure resin pipe has the characteristics of light pipe body, high compressive strength, small compressive deformation, good durability to medium, aging resistance, and convenient use. The fiber (steel wire) braided high-pressure resin pipe produced by our company has the characteristics of light pipe body, high compressive strength, small compressive deformation, good durability to medium, aging resistance, and convenient use.
