onnections refer to fittings and pipe fittings. Also known as pipe fittings tee or tee fittings, stainless steel equal diameter tee, tee joint, used at the branch pipe of the main pipeline.

A three-way connector has three openings, namely one inlet and two outlets; A type of chemical pipe fitting with two inlets and one outlet, which can be T-shaped or Y-shaped, with equal diameter pipe openings and reducing diameter pipe openings, used for the convergence of three identical or different pipelines. [1] The main function of a three-way valve is to change the direction of the fluid

The representation method is as follows: For equal diameter tees, such as "T3" (3 inches=DN80), the three-way rule represents an equal diameter tee with an outer diameter of 3 inches. For reducing tees, for example, "T4 × 4 × 3.5" (4 inches=DN100, 3.5 inches=DN90) represents a reducing tee with the same diameter of four inches but a different diameter of 3.5 inches. The material is generally 10 # 20 # A3 Q235A 20g 20G 16Mn ASTM A234 ASTM A105 ASTM A403, etc. The tee has an outer diameter range of 2.5 "-60" (2.5 inches=DN65, 60 inches=DN1500), a wall thickness of 3-60mm, and is welded from 26 "-60" (26 inches=DN650, 60 inches=DN1500). The wall thickness is 28-60mm. The pressure rating is Sch5s, Sch10s, Sch10, Sch20. Sch30, Sch40s, STD, Sch40, Sch60, Sch80s, XS; Sch80, Sch100, Sch120, Sch140, Sch160, XXS.
