The size head (reducing pipe) is a fitting used for pipe diameters.The forming process usually adopted is reducing diameter pressing, expanding diameter pressing or reducing diameter plus expanding diameter pressing.
A. Shrink/enlarge forming
The reduction process of the size head is to put the tube blank which is equal to the diameter of the big end of the size head into the forming die.According to the diameter of reducing pipe, it can be divided into one pressing or multiple pressing.
B. Stamping forming
In addition to using steel tube as raw material to produce the size head, the size head of part of the specification can also be produced by stamping process of steel plate.The shape of the drawing die is designed according to the size of the inner surface of the head.
Characteristics of reducing pipe: 1. When the flow rate of the fluid in the pipe changes, such as increase or decrease, and the flow rate requirement does not change much, the reducing pipe shall be used in the moulded reducing pipe.2, the entrance of the pump, in order to prevent cavitation.3, pressure reducing pipe and instrument, such as the flow meter, control valve joint, in order to cooperate with the instrument joint, also need to use reducing pipe.There are divided into concentric and eccentric two, concentric reducing tube is generally used in the vertical tube;Eccentric reducing pipe is used for horizontal pipe, and attention should be paid to mark the top level or the bottom level.
Forging reducing pipe manufacturer is used for two different diameters of the pipe connection accessories, the appearance is a big head is a small head, also known as size head.Pipes of different materials are equipped with reducing pipes of different materials to facilitate the connection of pipes.There are three ways of connecting PP reducing tubes.One is the butt welding type connection, in the pipe fitting diameter and the pipeline diameter to be installed in the same size, the installation personnel use hot melt machine heating after the completion of direct butt welding, this connection is firm and durable.
Seamless concentric size head in the production of the need to enlarge the size of the tube is smaller than the diameter of the large end of the reducing tube tube blank, with an internal die along the inner diameter of the tube blank expanding shape.The process of enlarging diameter mainly solves the problem that the reducing pipe with larger diameter is not easy to be formed by reducing diameter.In the process of reducing or expanding the diameter of the reducing tube, according to different materials and diameter, determine to use cold pressing or hot pressing.Under normal circumstances, try to use cold pressure, but for multiple diameter and cause serious work hardening, wall thickness thicker or alloy steel materials should be used hot pressure.Reducing pipe standards: gb, gb, gb and various non-standard high pressure stamping.
