What is a Equal Tee?
An equal tee is one of the most common pipe fittings which is used to either combine or split a fluid flow. It is a type of pipe fitting that is T-shaped having two outlets, at 90° to the connection to the main line. It is a short piece of pipe with a lateral outlet. A tee is used for connecting pipes of different diameters or for changing the direction of the pipe runs. Equal Tees are made of various materials and available in various sizes and finishes. They are extensively used in pipeline networks to transport two-phase fluid mixtures.
As a Duplex Steel Pipe fittings, ASTM A815 UNS S31803 BW Equal Tee has the features of high strength, excellent corrosion resistance and good weld-ability. Due to its various sizes, it is also economical and convenience in many industries, especially in the long-distance pipeline transportation.
Equal Tee begins as cast material, then it is rolled to the shape after reheating. This process is wrought. Most Butt Weld Fittings are also wrought fittings. Thus, ASTM A815 UNS S31803 Equal Tee is one type of ASME B16.9 Butt Weld Fittings.
