Elbow Hydraulic External Thread Pipe Fittings: Structure, Material And Application Analysis

Elbow Hydraulic External Thread Pipe Fittings is an indispensable part of the pipeline system, and its main role is to change the direction of the pipeline. It is usually curved, with a common Angle of 90 or 45 degrees, and has external threads. This external thread design is convenient to connect with other pipe fittings or equipment with internal threads, so as to achieve pipe extension and steering functions.

In terms of materials, there are many types. Stainless steel Elbow Hydraulic External Thread Pipe Fittings corrosion resistance is good, can be used in humid, acid and alkali complex environment, like the chemical industry to transport corrosive chemical liquid pipeline system, it can effectively prevent corrosion, prolong the service life. The carbon steel material has high strength and can withstand greater pressure, which can ensure the stability and safety of the pipeline system in the high-pressure hydraulic system such as the hydraulic pipeline of construction machinery. There are also some special alloy pipe fittings, with high temperature resistance, wear resistance and other excellent properties, suitable for hydraulic systems in the aerospace field, which require extremely high requirements for pipe fittings.

The external thread has high precision requirements, which is of great significance to the quality of pipe connection, high-precision external thread can be closely matched with the internal thread to avoid liquid leakage, because in the hydraulic system, small leakage may reduce the system pressure, affecting the normal operation of the equipment, and the external thread is generally used in the British or metric system and other standard specifications, easy to connect with the standard equipment and pipe. The surface of the external thread may be galvanized, nickel-plated, etc. The galvanized external thread is beautiful and has strong anti-rust ability, which can improve the service life of the pipe fitting.

In the field of application, in the hydraulic system, such as hydraulic pump station, hydraulic jack and other equipment, used to connect hydraulic tubing, hydraulic oil transmission and steering, due to the high working pressure of the hydraulic system, high requirements for pipe sealing and strength, Elbow Hydraulic External Thread Pipe Fittings can well meet the needs. In the building water supply and drainage system, it can be used to change the direction of the water pipe.
