Y tee pipe fitting hydraulic bulging and shape requirements
Feb 09, 2018

Y tee pipe fitting used to change the direction of the fluid, mainly used in the main branch pipe to the pipe, tee pipe fittings can be classified according to the size of their diameter, the production process will generally use its stainless steel, Alloy steel, plastic, cast steel, Arbitration Lek, pvc and other materials production.


Y tee pipe fitting has three of its mouth, mainly an import and two exits, or two imports, one export of a chemical tube, the shape of T-shaped and Y-shaped, with equal diameter nozzle, also has different diameter Spout for three identical or different pipe collection Department.


Tee pipe hydraulic bulging


The hydraulic bulging of the tee pipe is mainly a kind of forming process of expanding the branch pipe through the axial compensation of the metal material. The special hydraulic press is used in the process of making the tee pipe, Injecting liquid through the two horizontal side of the hydraulic cylinder simultaneously centering squeeze the tube, squeezed by the tube after the smaller the volume of the tube blank tube with the volume of the tube smaller and the pressure increases, when the three links When the branch tube expands the required pressure, the metal material flows along the cavity of the mold under the double action of the liquid pressure in the side tube and the tube blank to bulge the branch tube.


Tee pipe hydraulic bulging process can be a forming, high production efficiency, the tee and shoulder wall thickness have increased. Due to the seamless tee hydraulics bulging process equipment required for larger tonnage, the current domestic mainly for less than DN400 standard wall thickness tee manufacturing. The suitable forming materials are low carbon steel, low alloy steel and stainless steel which have a relatively low tendency to cold harden, and include some non-ferrous materials such as copper, aluminum, titanium and the like.
