Pipe Tee Fitting,ASME B 36.10,ASTM A234 WPB Equal & Reducing Tee

A Tee is a pipe fitting which is shaped like a “T” and has two outlets at 90° to the single inlet connection.
Tees are generally used to combine or split a fluid flow.
Straight Tees have inlets and outlets of the same size.
Pipe tee fittings are used for commercial as well as industrial applications. They are available in several different sizes. They are made from materials including carbon steel, alloy steel, stainless steel. There are different types of pipe tee fittings such as straight tee, female and male branch tee, male and female-run tee, reducing tee and wye tee.
Reducing Tees have inlets and outlets of differing sizes, the smaller one typically being at 90 degrees to the two lager ones.

1. Large size stainless steel tee

For production of large size stainless steel tee, two steel plates are placed into corresponding mould for compression molding first by hydraulic press. Then butt welding will be done to attach these two steel pieces together. Through this exact process, the maximum caliber of the seamed stainless steel tee we could produce reaches 100 inches.

2. Seamless stainless steel tee

In our company, there are cold press forming machines exclusive for production of seamless tee made of stainless steel. In addition, we can also produce seamless tee with larger size by hot press forming by mould process for customers.

3. Forged stainless steel tee

Through forging process, we are also able to manufacture stainless steel socket weld tee or threaded tee.

When the size of the branch is same as header pipes, equal tee is used and when the branch size is less than that of header size, reduced tee is used. The three sizes of a tee are End x End x Center. So if you want a tee that is 1’’ on both ends and 3/4’’ in the center it would be 1’’ x 1’’ x 3/4’’.Stainless steel tees, carbon steel tees and special grade tees are widely supplied by us to many industries such as power generation, petrochemical, shipbuilding, paper manufacturing, chemical, pharmaceutical, and fabrication.METLINE also manufactures not so regular buttweld lateral tee in stainless steel, nickel alloys, carbon steel and alloy steel grades.Depending on our customer requirements, we can manufacture and offer straight tees and reducing tees in various grades including 202, 304/304L, 904L, 316/316L, Duplex 2205, Alloy 20, Cupro Nickel, Monel Alloy 400, Inconel Alloy 625, Inconel Alloy 600, Hastelloy Alloy C276, and also in various Aluminium Grades.
