ASTM A234 WPB 4 Inch Pipe Tee Fittings For Pipe Connection

ASTM A234 WPB Reduced Tee, Wrought, 4 Inch, Oiled, Galvanized, Butt Welded, Pipe Connection.

Three links also known as pipe fittings three-way or three-way pipe fittings, three-way joints and so on. Mainly used to change the direction of the fluid, used in the main pipe branch. It can be classified according to the diameter of the pipe. Generally used carbon steel, cast steel, alloy steel, stainless steel, copper, aluminum alloy, plastic, argon leachate, pvc and other materials.
Classification
By size of pipe
The nozzle ends of the equal diameter tee are of the same size;
The size of the pipe is the same, and the size of the branch pipe is smaller than that of the supervisor.
By process
1. Hydraulic expansion
Hydraulic expansion of three-way is a forming process of expanding branch pipe by axial compensation of metal material. The process is to use a special hydraulic press to inject liquid into the tube billet equal to the diameter of the three links, and to squeeze the tube billet synchronously through the two horizontal side cylinders of the hydraulic press. The liquid in the tube billet increases with the volume of the tube billet.
The hydraulic expansion process of the three-way can be formed at one time, and the production efficiency is high, and the wall thickness of the supervisor and shoulder of the three-way is increased.
Because of the large tonnage of the hydraulic expansion process of seamless three links, it is mainly used in the manufacture of standard wall thickness three links less than DN400. The suitable forming materials are low carbon steel, low alloy steel, stainless steel, including some non-ferrous metal materials, such as copper, aluminum, titanium and so on.
