The structure of high-pressure steel wire braided rubber hose consists of a liquid resistant synthetic rubber inner layer, an intermediate layer, I or II or III layers of stainless steel wire braided improvement layer, and a highly weather resistant synthetic rubber outer layer.

Operating temperature: crude oil -40 ℃ -100 ℃, gas -30 ℃ -50 ℃, water moisturizing lotion below 80 ℃. In order to better and stronger ensure the safety of high-pressure hose products, attention should also be paid to their installation work. Related hose products should be classified and transported neatly. To prevent excessive bending and folding of the hose body, other hanging objects should not be stacked on the hose.

Secondly, it is prohibited to mix hoses with acids, alkalis, raw oil and solvents, flammable and explosive materials; High pressure hose products should not come into direct contact with goods with sharp edges. When transporting high-pressure hoses, do not drag them around. For overweight products, lifting machinery or specialized machinery should be used for loading and unloading to avoid accidental damage to high-pressure hoses.

When the high-pressure hose used is subjected to working pressure exceeding its support point in the radial direction, it may suddenly bend like a load-bearing component or cylindrical compression spring, losing the reliability of its parallel line shape. If the gas pressure borne by the high-pressure hose exceeds a certain working pressure value it can support, it will also cause imbalance.

In the field of high-pressure rubber hoses, according to regulations, the experimental pressure of high-pressure steel wire braided rubber hoses is twice the working pressure, and the engineering blasting pressure is generally 3-4 times the working pressure, which is qualified. So, how to test the pressure of high-pressure hoses?

Firstly, in terms of appearance, if it has good glossiness and high extensibility, then it belongs to a good product; Secondly, the pressure resistance test of mining high-pressure rubber hoses is divided into bottom pressure test and high-pressure test. The pressure for the bottom pressure test of mining high-pressure rubber hoses is 1MPA, held for five minutes, and the test substance is water. If there is no liquid leakage in the pipe body, it is qualified. The test substance for high-pressure testing of mining high-pressure rubber hoses is water. If there is no explosion, it is qualified.

In addition, when conducting high-pressure engineering blasting tests, attention should be paid to the surrounding environment and pressure bearing mechanical equipment should be inspected in a closed natural environment. And it is prohibited for others to accompany to prevent accidents.

After inspection, attention should also be paid to high-pressure steel wire braided rubber hoses in daily applications, and try to avoid using rubber hoses to radiate heat to prefabricated components. Clothing insulation materials should prevent rubber hoses from being damaged by external factors, such as long-term friction on the surface of prefabricated components. The viscosity of oil decreases, which easily leads to leakage, reduced efficiency, decreased compressive strength of lubricating grease film, and mechanical equipment damage is converted into cementite and sediment. Hydraulic oil air oxidation accelerates oil deterioration; Skeleton sealing, premature brittleness of high-pressure rubber hoses, etc.
