Because plastic coated hose connector design unreasonable phenomenon caused by the failure

Pack plastic hose connector design is essential, which is the core technology of hose assemblies. In actual operation, including plastic Hydraulic adapters connector design is often not a good grasp of various key points, it will cause a variety of failures. Because plastic coated hydraulic hose assemblys connector design failures caused by the unreasonable phenomenon is most prevalent are withheld at the inner tube longitudinal cracks appear and circumferential cracks are two, there are other symptoms, but not common. There are the following two: 1 withhold longitudinal cracks appeared at the inner tube site withhold the end of the sleeve, the inner tube vertical microcracks appear, once a crack running through, it will result in failure of two hydraulic tube fitting assemblies withheld at the inner tube circumferential cracks appear in actual use, and the testing process is also one of the more common symptoms. Inner tube circumferential cracks appeared after the weak link here will become, along with the gradual extension circumferential cracks, often in the form here leak, resulting in failure of hose assemblies.
