How are qualified hydraulic hoses refined?

Hydraulic hose, also known as hydraulic hose, steel wire high-pressure pipe, hydraulic pipe, etc. According to the production process, it is generally divided into steel wire braided hydraulic hoses and steel wire wrapped hydraulic hoses. Commonly used for the transportation and liquid transmission of petroleum based and water-based liquids with certain pressure (higher pressure) and temperature.

From the definition of hydraulic hoses, we can roughly understand that a qualified hydraulic system must have high pressure resistance and be suitable for different temperatures. Of course, this is just its basic "literacy". The application environment of hydraulic hoses determines its "not simple". Today, the editor will talk to you about: "How is a qualified hydraulic hose" refined "? ”

1、 High voltage resistance performance test

Simulating practical working conditions, hydraulic hoses are mainly used in high-pressure or ultra-high pressure fields, which ensures that they must pass pressure resistance performance testing. The detection pressure is generally 1.5 times the maximum working pressure.

2、 Performance test for high and low temperature resistance

Simulate practical working conditions and conduct performance tests under high or low temperatures, alternating high and low temperatures, alternating high and low pressures, or alternating low and high pressures under pressure.

3、 Pulse fatigue life performance test

Simulate actual practical working conditions, apply pressure shocks of a specified frequency and frequency to the interior of hydraulic hoses, and measure their service life.

4、 Blasting pressure performance test

Continuously apply pressure inside the hydraulic hose to cause it to burst, and measure the maximum working pressure value of the hose.

5、 Other performance tests

Due to the wide range of applications and frequent use in special environments, some specially customized hydraulic hoses sometimes need to undergo performance tests in terms of expansion deformation, wear resistance, insulation, corrosion resistance, and other aspects.

A qualified hydraulic hose must undergo one or more performance tests before it can be finally sold to the market and applied in various fields.
