From which aspects to detect high pressure hose is good or bad

Simple to introduce how to detect the quality of high pressure hose:

First of all, starting from visual inspection, the wall thickness of the rubber hose with poor quality is uneven, the steel wire is too tight or the number of layers is too small, the rubber hose will deform greatly under slight pressure, and it is easy to be corroded. The adhesive force between the rubber layer and the steel wire layer is lack, which will make the pipe wall easy to burst.

Secondly, improper selection of the buckling amount and buckling speed during the assembly of the hose and the joint, or unreasonable selection of the structure, material and size of the joint, can lead to too tight or too loose pressure between the hose and the joint, resulting in early damage to the joint.

In addition, the joint design is unreasonable, the processing quality is poor, will also constitute the internal rubber damage; If the joint material is not properly selected, it is easy to produce deformation in the process of buckling, thus affecting the quality of buckling, so that the life of the hose is shortened.
