ASTM A815 UNS S31803 BW Equal Tee Duplex Stainless Steel Butt Weld Fittings

ASTM A815 UNS S31803 BW Equal Tee Duplex Stainless Steel Butt Welding Equal Tee


BW Equal Tee Duplex fittings are used in various industries, including oil and gas, chemical processing, desalination plants, and offshore applications. They are commonly used in piping systems where equal flow distribution or system integration is required.

Equal Tee ASTM A815 WP-S UNS S31803 is a Duplex Stainless Steel Tee. It is ferrite or austenite stainless steel with a microstructure of 50:50.


BW Equal Tee Duplex is made from duplex stainless steel, which is a corrosion-resistant and high-strength material. Duplex stainless steel is composed of a balanced mixture of austenite and ferrite phases, offering excellent resistance to corrosion, including pitting and crevice corrosion.


Butt Welding (BW) Tee Types

BW Tee is categorized into two types according to branch diameters and functions there are:

Equal Tee: Three branches of tee have same diameters. Also named as Straight Tee.

Reducing Tee (Reducer Tee). : The branch diameter is smaller than main diameter. The reducing tee is usually described as NPS diameters in 4” x 4” x 3”, where 4” is the main line pipe diameter, and 3” is the reducing branch.

ASTM A815 is the standard specification for Wrought Ferritic, Ferritic/Austenitic, and Martensitic Stainless Steel Piping Fitting. This specification covers two general classes, WP and CR. Class WP fittings are subdivided into four classes:

WP-S, seamless products.

WP-W, welded products.

WP-WX, Pipe fittings which contain welds where all welds have been radiographed.

WP-WU, fittings that contain welds where all welds have been ultrasonically tested.
