In the last piece, we learned how to choose high pressure hose assembly. Besides the choice, we should also judge the quality of the hose assembly. Generally, we can judge it based on the methods as follow.
Size of high pressure hose assembly
There is size deviation in the practical usage. Thus the diameter and reinforcement will fluctuate during the work. However, if the fluctuate range beyond the allowance, it will affect the crimp quality. So as the hose assembly. Therefore, you should check them strictly if they meet the requirements.
Wall thickness deviation
Because of the eccentricity of rubber layers, the deviation of wall thickness may over large. But if the deviation beyond the allowance, it will affect the uplift strength as well as seal property. Worse more, it will incline the connector. Therefore, you’d better control the wall thickness deviation strictly. In the case, the deviation should be over 0.5mm.
Adhesion among rubber layers
High quality hydraulic hose is an entirety. That’s to say the layers should have great adhesion and be a entirety with each other. Only this can meet the tech requirements on connector crimping. Then guarantee the quality of assembly. Thus the adhesion should be better than the standard.
Besides, the appearance is also important. It affect the assembly as well as the usage quality. Any bubble, blowhole or damage will cause reinforcement expose. Then, it will be corroded. The pressure resistance will reduce as well. This affect the hose assembly and even cause serious accident. Thus you should focus on the appearance.
