What are hydraulic fittings?
Hydraulic pipe fittings are a kind of pipe fittings. They are mainly used in hydraulic systems. They are components connecting hydraulic oil pipes and hydraulic oil pipes. They are very important parts in hydraulic equipment. They are used to prevent the leakage of working media and the intrusion of external dust and foreign objects. Generally, hydraulic pipe joints are commonly used, including sleeve type pipe joint, welded pipe joint, transition type pipe joint, three-way pipe joint, non-standard pipe joint, flared pipe joint, right angle pipe joint, rotary pipe joint, etc.

What is the difference between hydraulic pipe fittings and ordinary pipe fittings
Compared with ordinary pipe fittings, the main difference lies in the pressure bearing capacity. Because hydraulic pipe fittings are used in hydraulic equipment, the hydraulic pressure is very amazing. The impact force of sudden burst of hydraulic oil pipe is very large. This impact force cannot be replaced by ordinary pipe fittings. Ordinary pipe fittings can only bear the pressure of 0.5 air pressure at most, while hydraulic pipe fittings bear much greater 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. The ordinary key cannot be used in hydraulic equipment. In addition to hydraulic equipment, hydraulic pipe fittings can also be applied to ordinary pipelines.
Requirements for hydraulic pipe fittings
Hydraulic pipe fittings are used in hydraulic systems. Most of the leakage problems in hydraulic systems occur in pipe fittings. Therefore, the choice of pipe fittings is very important. Standard hydraulic pipe fittings should meet the requirements of convenient assembly and disassembly, firm connection, reliable sealing, small size, large flow capacity, small pressure drop, and good manufacturability.
In addition to the requirements of the pipe fittings, the hydraulic system in order to prevent leakage, attention should also be paid to the selection of pipes, the determination of pipe fitting forms (including pipe fitting design, gaskets, seals, selection of hoop leak-proof coatings, etc.), the design of pipes (including elbow design, selection of pipe supporting points and supporting forms, etc.) and the installation of pipes (including correct transportation, transportation, storage, cleaning, assembly, etc.) should be considered clearly.
