reducing pipe It is used for two different calibers Pipe The shape of the connected accessories is big at one end and small at the other, also known as the small end. Pipes of different materials are equipped with reducers of different materials for convenience The Conduit Connection of. PP reducer can be connected in three ways. One is butt welding connection pipe fitting The diameter is the same as that of the pipeline to be installed. The installation personnel use the hot-melt machine to heat it and then directly butt weld it. This connection mode is firm and durable. The other is socket type connection, that is, the sleeves are welded on both ends of the pipe fittings, and the pipes are directly inserted into the pipe fittings and sealed (sealed) with welding rods during installation. This installation method is convenient and fast. Another is flange Type reducer, that is, the neck flange is welded on both ends of the pipe fitting, and the installation personnel can directly fasten it with the screw opening during installation. This installation method is of sufficient pressure, fast and easy to disassemble, but the cost is increased.
Production of seamless reducer:
PP reducer (reducer) is a kind of pipe fitting used at pipe reducer. The commonly used forming process is reducing pressing, expanding pressing or reducing plus expanding pressing, and stamping forming can also be used for reducing pipes of certain specifications.
The reducing forming process of the reducer is to put the tube blank with the same diameter as the big end of the reducer into the forming die, and make the metal move along the die cavity and shrink to form by pressing along the axial direction of the tube blank. According to the size of reducer, it can be divided into one press forming or multiple press forming.
In addition to using steel pipes as raw materials to produce reducers, the reducers of some specifications can also be produced by stamping process with steel plates. The shape of the punching die used for drawing is designed according to the size of the inner surface of the reducer, and the blanking steel plate is punched and drawn by the punching die.
