There are three forming methods for tees, small seamless tees usually use hydraulic bulging and hot extrusion method, and large diameter tees usually use butt welding.
The cut pipe is placed in a hydraulic mold and liquid is filled into the pipe. Hydraulic pressure pushes the pressure in the branch out of the fixed hole in the mold, resulting in good surface finish.
Tees made of large diameter, thick wall thickness, or challenging special materials are manufactured using hot extrusion methods, which cannot be manufactured using hydraulic expansion methods. In the hot extrusion method, by using pipes with a diameter greater than the finished product size and with the help of extrusion tools, the branch outlet is squeezed out of the pipe.
For the production process of titanium tees with larger diameters, generally OD133mm and above, welded pipes are used due to the lack of seamless pipes in the basic pipe material or the relatively high cost of seamless pipes. Alternatively, the plates are cut into two corresponding shapes and extruded into a mold to weld the two formed half tees into finished products.
