Information

The pipe nipple is a connection tool between the pipe and the pipe, and the connection point between the component and the pipe that can be disassembled and assembled. It plays an indispensable and important role in pipe fittings. It is one of the two main components of hydraulic pipelines. Pipe joints are used for linear connection of instruments, etc. The connection forms are socket welding or threaded connection. Mainly used for small-caliber low-pressure pipelines, used in places that need to be frequently assembled and disassembled, or as the final adjustment of threaded pipe fittings. The structure should adopt a metal surface contact sealing structure. The structure of gasket sealing is usually used for conveying water, oil, air and other general pipelines, and it is made of malleable cast iron. In addition, the use requirements and price are also factors to be considered when selecting.  

There are many types of pipe joints. Commonly used pipe joints can generally be divided into two types: hard pipe joints and hose joints. According to the connection method of pipe joints and pipes, there are three types of hard pipe joints: flaring, ferrule and welding, while hose joints are mainly crimped hose joints.  

There are also different connections between pipes and pipe joints in hydraulic systems. The screw-in end of the pipe uses a connecting thread. The taper thread relies on its own vertebral body to tighten and uses PTFE and other materials for sealing operation, and is mainly used in medium and low pressure hydraulic systems. The sealing effect of fine thread is very good, and it is often used in high-pressure systems, but it requires the use of combined washers or O-rings to close the end face, and sometimes copper washers are used, which are more suitable for connecting pipe walls. In thick pipes, the main components are joint body, connection pipe and nut. When in use, the joint body is embedded in the target, and the end face is sealed with the aforementioned gasket. The joint body and the nozzle are sealed with rubber, and sometimes spherical sealing is used.

Since the pipe nipple is a detachable connection element, it must meet the requirements of normal connection stability, strong sealing, reasonable size, small pressure loss, good process performance, etc., but also must meet the requirements of convenient disassembly and assembly . Therefore, do not underestimate the small pipe joints, because only its existence can support the existence of the entire hydraulic system.
