Talking about the Key Points of Prolonging the Service Life of High Pressure Hose Joints
Before the high-pressure hose joint, I gave a detailed description of him through pictures and language. We explained the high-pressure hose joint from its size, model, use, performance and other aspects. Everyone should be familiar with the high-pressure hose joint.
Now we don't need to talk about anything else. Let's get down to business. What we want to introduce to you today is the relevant content of the joint - the method of prolonging the life of the high-pressure hose joint.
High and low pressure rubber hose joints are of two types, one is to peel the outer glue, and the other is not to peel the outer glue. The groove of the joint sleeve of the type to peel the outer glue should not be too sharp, or the reinforcement layer of the rubber hose will be damaged. Correct crimping of the joint is critical to the safety and normal operation of the high and low pressure hose joint assembly. There are many types of high and low pressure rubber hose joints. Appropriate joints should be selected, and the design of the joint sleeve should be standard and reasonable. Sharp grooves and non-standard sizes will break the steel wire reinforcement layer. When crimping the joint, the amount of crimping shall be determined according to the inner diameter and outer diameter of the rubber hose.
