Manufacturers of high-pressure oil pipes have summarized the following situations: The following are:
1. Subject to frequent and severe stress. High-pressure hose ruptures are usually not caused by excessive static pressure, but by the severity and frequency of pressure shocks. In the operation of construction machinery, the oil pressure in the oil pipe will repeatedly increase or decrease, which will cause frequent pressure shocks to the oil pipe, resulting in aggravated damage to various oil seals, blistering and rupture of rubber pipes, and loose and leaking pipe joints. Therefore, during the operation, the tightening of the valve stem should not be too violent and must be kept smooth. High pressure oil pipe manufacturer
2. The operating temperature of the oil is too high. In the operation of construction machinery, the hydraulic system heats the oil due to power loss and affects the external temperature (especially in summer), resulting in a sharp rise in oil temperature. The higher the operating temperature of the oil, the easier the rubber is to age, the elasticity becomes poor, the strength and sealing performance decrease, and the hose will break quickly. Therefore, in operation, when the temperature of the hydraulic system is too high and rises too fast, the cause should be identified and eliminated in time. In summer operations, especially continuous operations, necessary cooling measures should be taken.
3. The selection and installation of the hose is unreasonable. When replacing the high-pressure hose, the length of the hose, the number of steel wire layers, the shape and size of the joint should be reasonably used, and the bending degree of the hose should be minimized as much as possible; when tightening the joint nut, do not make the hose bend, bend and Twisting can greatly reduce the service life of the hose; protection should be taken to prevent damage to parts that are prone to friction.

Each product has its own requirements for use, and high-pressure oil pipes are no exception. Today, I will analyze seven main usage requirements for high pressure tubing:
1. The internal working pressure (including pulse pressure) of the high-pressure oil pipe shall not exceed the maximum working pressure specified by the hose design.
2. Do not use it under conditions that exceed the working environment requirements of high-pressure oil pipes.
3. The high-pressure oil pipe is only suitable for the requirements of the design conveying medium. High pressure oil pipe manufacturer
4. The use and installation shall not be less than the bending radius of the high-pressure oil pipe design.
5. Do not use high-pressure oil pipes in a twisted state.
6. The crimping amount of the high-pressure oil pipe must meet the requirements, and the size and accuracy of the joint must meet the standard requirements.
7. The high-pressure oil pipe is a wearing part, which should be checked and replaced regularly. High pressure oil pipe manufacturer
The above points are the use requirements and improper situations of high-pressure oil pipes shared by high-pressure oil pipe manufacturers. I hope they can be a substantive reference for all good friends. You can also bookmark them. It is also good to have a preview for the future. If you have any questions, you can also consult us directly. Welcome your inquiries.
