rubber Sandblasting pipe Common faults of outer rubber layer:

1. Appearance crack of rubber sand blasting pipe

In cold environment, cracks on the outer surface of the rubber sand blasting pipe will bend the rubber sand blasting pipe. If cracks appear on the outer surface of the hydraulic hose, observe whether the rubber in the hydraulic hose has cracks, and decide whether to replace the hydraulic hose immediately. Therefore, do not move the rubber sand blasting pipe or repair the hydraulic system at will in the cold environment. If necessary, do it indoors.

If you need to work in a relatively cold environment for a long time, please replace the cold resistant rubber hose.

2. Bubbles will appear on the surface of rubber sand blasting pipe

The bubbles outside the rubber sand blasting pipe are caused by unqualified quality or improper use of the rubber sand blasting pipe.

If the rubber sand blasting pipe bubbles in the middle, it is mainly due to the production quality problem of the rubber sand blasting pipe, and the qualified hose should be replaced in time. If the hose connector bubbles, it may be due to improper installation of the connector.

The connection end of the steel wire braided winding rubber hose joint and the rubber hose has two forms of folding and buckling. The detachable joint sheath and joint core are hexagonal, and the outer wall of the joint core is conical, which is convenient for the assembly and disassembly of the rubber hose.

After the joint core is connected with the nut, insert the steel wire to prevent loosening. The buckle type rubber hose joint consists of a joint jacket and a joint core. During assembly, it is necessary to peel off the outer rubber layer, put the connector sleeve into the connector core and tighten it, and then use the mold on the special equipment to buckle the rubber hose, so that the rubber hose can obtain a certain amount of compression and achieve a tight connection.

3. The rubber sand blasting pipe is not broken, but has a large amount of oil leakage

If no crack is found on the hydraulic hose, a large amount of oil leaks. The reason is that the internal rubber of the hydraulic hose is corroded and scratched when it passes through the high-pressure fluid flow, until a large area of steel wire layer leaks, resulting in a large amount of oil leakage. This failure usually occurs at the bend of the pipe. The rubber sand blasting pipe shall be inspected and replaced to ensure Rubber sand blasting pipe The bending radius of shall meet the technical requirements in use.

4. The external rubber layer of the hydraulic rubber hose is seriously damaged, and the surface is slightly cracked.

This is the natural aging of hydraulic hose due to long service time.

Due to aging and deterioration, the outer layer is continuously oxidized to make its surface brittle. With the extension of time, the embrittlement layer deepens. As long as the rubber sand blasting pipe is slightly bent in use, tiny cracks will appear.
