Schedule 40 Welded Steel Pipe Nipples - Galvanized

Pipe nipple is a connecting tool between pipes and a connection point between components and pipes that can be disassembled. It plays an indispensable role in the pipe fitting, and it is one of the two main components of the hydraulic pipeline. The connection form of pipe nipple includes socket welding or threaded connection. It is mainly used for small-diameter low-pressure pipeline, which is often installed and disassembled, or as the final adjustment of the pipeline with threaded pipe fittings. The structure form should adopt the metal surface contact sealing structure, which is usually used to transport water, oil, air, etc. In general, malleable cast iron is used for the pipeline. In addition, the use requirements and prices are also factors to be considered in selection.

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 red copper washer is also used. It is more suitable for connecting pipes with thick wall. 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.
