Usage: The pipe joint is a connection tool between pipes and pipes, and it is a connection point between components and pipes that can be disassembled and assembled. It plays an indispensable and important role in pipe fittings, and it is one of the two main components of hydraulic piping. Pipe fittings are used for linear connections such as instruments, and the connection forms are socket welding or threaded connections. It is mainly used for small-diameter low-pressure pipelines, for parts that need to be assembled and disassembled frequently, or for the final adjustment of pipelines using threaded fittings. The structural form of gasket sealing is usually used to transport water, oil, air and other general pipes, and is made of malleable cast iron materials. In addition, the requirements and price are also factors to consider when choosing.

Material: 16Mn 16Mn steel belongs to carbon manganese steel, the carbon content is about 0.16%, and the yield point is equal to 343mpa (the strength level belongs to 343mpa grade). 16Mn steel has less alloy content and good weldability, so it generally does not need to be preheated before welding. However, since the hardening tendency of 16Mn steel is slightly larger than that of mild steel, preheating measures are required to prevent cold cracks when welding at low temperatures (such as winter open-air operations) or on large rigidity and large thickness structures.
