What is the difference between hydraulic fittings and ordinary fittings

Hydraulic pipe fittings are used in hydraulic systems. Most of the leakage problems in hydraulic systems occur in pipe fittings. Therefore, the selection of pipe fittings is very important. Standard hydraulic pipe fittings should meet the requirements of easy assembly and disassembly, firm connection, reliable sealing, small size, Large flow capacity, small pressure drop, good manufacturability and other requirements.

In addition to the requirements of pipe fittings, in order to prevent leakage, the hydraulic system should also pay attention to the selection of pipe materials, the determination of the form of pipe fittings (including the design of pipe fittings, gaskets, seals, ferrules, the selection of anti-leakage coatings, etc.), the design of piping systems (including bending Pipe design, selection of pipe support points and support forms, etc.) and pipe installation (including correct transportation, storage, cleaning, assembly, etc.) must be carefully considered.

Compared with ordinary pipe fittings, the main difference between hydraulic pipe fittings is the pressure bearing capacity. Because hydraulic pipe fittings are used in hydraulic equipment, the hydraulic pressure is very amazing, and the impact force of the sudden burst oil of the hydraulic oil pipe is very large. This impact force is Ordinary pipe fittings cannot be replaced. Ordinary pipe fittings can usually only withstand a pressure of 0.5 air pressure at most, while hydraulic pipe fittings have to withstand a lot of pressure.

Due to the different pressure-bearing capacity, there are certain differences between hydraulic pipe fittings and ordinary pipe fittings in the field of use. Common keys cannot be used in hydraulic equipment. In addition to hydraulic equipment, hydraulic pipe fittings can also be used in ordinary pipelines.
