Forged Steel Pipe Fittings Asme B16.11 9000lbs Forged 45 Degree Y Branch Lateral Tee Forged Steel Fittings

Using forging machinery to apply pressure on metal billets, The plastic deformation is made to obtain the machining method of forgings with certain mechanical properties, certain shape and size. Through the constant beating of the fittings, Compaction and welding the original segregation, porosity, porosity and slag inclusion in the ingot, It's getting closer, improves the plastic and mechanical properties of the metal. Forging pipe fittings mainly include forging flange, Forged diameters, Forging three links, etc. q235, are the main materials for forging fittings q345, 16 mn, 20#, 35#, 45#, 40Cr, 12Cr1MoV, 30CrMo, 15CrMo, 20G, etc. Corresponding to the forged fittings are cast fittings, The mechanical properties of castings are lower than those of forgings of the same material, The casting fittings melt the metal into a liquid that meets certain requirements and pour it into the mold, The process of obtaining castings (parts or blanks) with predetermined shape, size and properties after cooling solidification and cleaning.

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.
The three links are pipe fittings and pipe connections. Also known as pipe fittings three-way or three-way pipe fittings, stainless steel equal diameter three-way joint, used in the main pipe to branch pipe.
The three-way is a kind of chemical pipe fittings with three openings, one inlet, two exits, or two imports and one outlet, which have T shape and Y shape, equal diameter pipe mouth, and different diameter pipe mouth, which are used for three identical or different pipe pools. The main function of the three links is to change the direction of the fluid.
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.
2. hot pressing
The three-way hot pressing forming is to flatten the tube billet larger than the three-way diameter to the size of the three-way diameter. The tube billet is heated and put into the forming die. Under the action of pressure, the tube billet is compressed radially, and the metal flows in the direction of branch pipe and forms branch pipe under the drawing of punching die. The whole process is formed by the radial compression of the tube billet and the tensile process of the branch pipe. Unlike the hydraulic bulging three-way, the metal of the hot-pressed three-way branch pipe is compensated by the radial motion of the tube billet, so it is also called the radial compensation process.
Due to the use of heating to press the three-way, the material forming equipment tonnage is reduced. The hot-pressing tee has a wide adaptability to the material, which is suitable for low carbon steel, alloy steel and stainless steel, especially for large diameter and thick pipe wall.
