What are the applications of pipe joint in daily life?

There are many kinds of pipe joints. Commonly used pipe joints can be divided into hard pipe joints and hose joints. According to the connection mode of pipe joint and pipe, there are three types of hard pipe joint: flared type, ferrule type and welding type, and the hose joint is mainly the compression type rubber pipe joint.

In the hydraulic system, the connection mode of the pipe and the pipe joint is also different. The screw in end of the pipe adopts the connection thread. Taper thread is mainly used in the middle and low pressure hydraulic system because of its own vertebral body tightening and sealing operation with polytetrafluoroethylene and other materials. The sealing effect of fine thread is very good, and it is often used in high-pressure system, but it needs to use combination washer or O-ring to seal the end face, and sometimes copper washer is also used. It is more suitable for connecting pipes with thick wall, and its components mainly include joint body, connecting pipe and nut. In use, the joint body is embedded in the target, and the end face is sealed with the gasket mentioned above. The rubber seal is used between the joint body and the connecting pipe, and sometimes the spherical seal is also used.

Since the pipe joint is a detachable connecting element, it must meet the requirements of stable connection, strong sealing, reasonable size, small pressure loss, good process performance, etc., as well as the requirements of convenient disassembly and assembly. Therefore, do not look down on those small pipe joints, because only its existence can support the existence of the entire hydraulic system.
