Teach you five steps to increase the lifespan of high-pressure oil pipes

Layout of high-pressure rubber hose products: The layout of steel wire braided rubber hose is composed of a liquid resistant synthetic rubber inner layer, middle layer, I or II or III layers of steel wire braided reinforcement layer, and a synthetic rubber outer layer with excellent weather resistance.

Product use: Steel wire reinforced hydraulic rubber hoses are important for mining hydraulic supports, oilfield development, suitable for engineering construction, lifting and transportation, metallurgical forging, mining equipment deployment, ships, injection molding machines, agricultural machinery, various machine tools, and the transportation of kerosene based (such as mineral oil, soluble oil, hydraulic oil, fuel, lubricating oil) liquids with certain pressure and temperature, water-based liquids (such as emulsions, oil-water emulsions, water), gases, and liquid transmission in various industrial sectors.

We have provided the common faults and causes of high-pressure oil pipes, so in order to use them effectively, it is necessary to avoid these faults. So, how to deal with them? Let's take a brief look below:

When the high-pressure oil pipe needs to be bent, the bending radius should not be too small and should be greater than 9 times the outer diameter. There should be a straight section at the connection between the high-pressure oil pipe and the joint that is greater than twice the outer diameter of the pipe.

When installing the high-pressure oil pipe, it should be avoided to be in a tight state. Even if there is no relative movement between the two ends of the high-pressure oil pipe, the hose should be kept loose. The tensioned high-pressure oil pipe will expand and its strength will decrease under pressure.

3. Do not twist the high-pressure oil pipe during installation. Slight twisting of the high-pressure oil pipe may reduce its strength and loosen the joint. When assembling, the joint should be tightened on the high-pressure oil pipe instead of tightening the high-pressure oil pipe on the joint.

4. The layout of high-pressure oil pipes should avoid heat sources as much as possible and be kept away from the engine exhaust pipe. When necessary, casing or protective screen devices can be used to prevent the high-pressure oil pipe from deteriorating due to heat.

5. In areas where high-pressure oil pipes need to cross or may rub against mechanical surfaces during operation, protective devices such as high-pressure oil pipe clamps or springs should be used to prevent damage to the outer layer of the hose.
