Tee is one kind of pipe fittings.Its connection form is that the tee and steel pipe weld directly. The main manufacture standards are generally GB/T12459, GB/T13401, ASME B16.9, SH3408, SH3409, HG/T21635, HG/T21631, SY/T0510.

Classification

1.according to the pipe diameter points generally have equal tee, reducing tee, etc.

2.according to the direction of the branch points have equal tee and oblique tee.

3.according to the material is carbon steel, alloy steel, stainless steel, copper, PVC tee, etc.

4.according to the connection points are common tee , card sets of tee, socket tee.

5.Three expressed as follows: For Tee, such as "T6" Tee said outside diameter is 6 inches Tee.

     For reducing tee, such as "T4 × 4 × 3.5" represent the same diameter of four inches to 3.5 inches in diameter reducing tees. Pressure rating and elbow pressure levels are the same, which is the same size range.

     Production process:Tee joint is forming will be bigger than the three links of the diameter of the tube billet, flattening diameter size, about to tee at the site of the tensile branch open a hole;heated tube, placed in the mold, and the contents in the tube drawing into a die manifold;Under the action of pressure pipe by radial compression, the radial compression in the process of metal flow in the direction of branch pipe and branch pipe formed under tensile of progressive die.Unlike hydraulic bulge forming tee, branch pipe tee joint metal is of the pipe by the radial motion compensation, so also known as the radial compensation technology.

     Due to adopt heating after pressing tee, material forming required equipment tonnage is reduced.Hot pressing tee with wider adaptability of material, is suitable for low carbon steel, alloy steel, stainless steel materials;Especially large diameter and wall thickness of tee, usually use this forming process.
