Standard
Specification
A tee, also known as a tee fitting, is a pipe fitting that has a "T"-shaped design. It is used to connect three pipes or tubes at right angles to one another, forming a T-junction. Steel tees are commonly used in piping systems to distribute or combine fluid flow in various directions.
Material:
Carbon Steel --- ASTM A234 WPB/WPC, ANSI B 16.9, ASTM A105/A106/A53, API 5L GR.B/A671-CC-70/A515-50/A135-A/A179-C
Stainless Steel --- ASTM 403 304/304L,316/316L,316Ti,321,317L,310S
Alloy Steel --- ASTM A234 WP1/5/9/11/12/22/91
Specification:
NPS from 1/2'' to 36'', DN from 15 to 900,
WT: 2-80mm, SCH 40/80/XXS
Features:
There are three female openings in a T shaped pipe tee.
There are straight pipe tees which have the same size openings.
Reducing pipe tees have one opening of different size and two openings of the same size.
There are sanitary pipe tees which are used in waste lines. These kind of pipe tees have a curved branch which is designed for a clean out plug. They are used to prevent obstruction of waste.
A cross pipe tee has four equal sized female openings.
A wing pipe tee has lugs to fasten the fitting to a wall or stud.
A compression pipe tee uses compression fittings on two or more ends.
A test pipe tee has a threaded opening. This opening is used in conjunction with a threaded plug for a clean-out opening on a drain pipe.

Process
Hydraulic Bulge Method
To start with hydraulic bulge method uses high pressured fluid to shape the metal or material. The process begins with the receiving inspection of the piece and cutting it to the required size than the hydraulic pressure slowly generates a bulge commonly in the middle of the piece yet, the bulge area can be changed by demand. The bulging method can be represented below figure, at the cold extrusion step, as it can be seen the fluid tries to push the zone that is not supported or pressed intentionally. Then the piece is heated to ensure that it is reliable and rigid. This heat treatment makes the piece almost liquid to have an even distribution of metal and not to have cracks. After the heat treatment, the piece is cleaned and shot blasted, in other words, machining to have a perfect and smooth surface. Lastly, the piece is coated to resist rust and for other corrosion reasons.
Hot Extrusion Method
Like the hydraulic bulge method, the hot extrusion method also starts with an inspection of pieces and cutting. Then the pipe is heated to prepare it for extrusion since cold extrusion can break the pipe. After that, a spherical metal piece pulled through to cut this heating and pulling called forming process. Although this method is called “hot” extrusion and the piece is heated while the forming process, is applied heat treatment to the piece with the same reason in hydraulic bulge method. Besides, the rest of the process is the same with the hydraulic bulge method machining, cleaning, beveling, and coating.
