Key points for prolonging the service life of high-pressure hose joints
There are two types of concave convex compression hose joints: the one that needs to be peeled off and the one that does not need to be peeled off. The joints are also different. The groove of the connector sleeve that needs to be peeled off should not be too sharp, or the reinforcing layer of the hose will be damaged. Correct crimping of the joint is critical to the safety and normal operation of the concave convex compression hose joint assembly. There are many types of concave convex compression hose joints. Appropriate joints shall be selected, and the design of joint sleeve shall be of reasonable size. Sharp grooves and non-standard sizes will break the steel wire reinforcement layer. The amount of joint crimping shall be determined according to the inner diameter and outer diameter of the rubber hose.
Handling and storage of hose and hose assembly
1. The storage period of high-pressure rubber hose connector or high-pressure rubber hose connector assembly shall be as short as possible. If long-term storage cannot be avoided, the products shall be inspected and tested before use.
2. During the storage of high-pressure rubber hose or rubber hose assembly, especially during the lasting storage, the storage conditions shall be able to provide the best protection and minimum damage to the concave convex rubber hose or rubber hose assembly.
3. High pressure hose joints should always be handled carefully. It shall not be dragged on the sharp and rough profile, and shall not be subject to bending and flattening.
It reflects the protection of high-pressure hose joints in many aspects, which delays his life. The protection of high-pressure rubber hose joints is very helpful to our customers and manufacturers. We are not afraid to pay more attention to such articles, so that we can take good care of your high-pressure rubber hose and joint accessories no matter what the environment.
