BW Equal Tees Galvanized Carbon Steel Pipe Fittings

BW equal tees are the most used tees in the all types of tees.There are equal tee and reducing tee.Galvanized carbon steel pipe fittings have better corrosion resistance than carbon steel fittings.

Rated 4.7/5 based on 359 customer reviews

BW equal tees are T-shaped pipe fittings with three branch pipes. A steel pipe tee is used to divide pipes to adjust flow and change direction.Due to the Galvanized coating enhanced the corrosion resistance,Galvanized carbon steel pipe fittings are commonly used in corrosive environment.


There are two types of tees: Equal Tee and Reducing Tee.


Equal Tee

Equal diameter tee, also known as straight tee, the branch diameter of the tee is the same as the pipe diameter of the tee.


Reducing Tee

The reducing tee has two outlets cut at 90 degrees with the main pipe, and the size of the branch pipe is smaller than the port of the pipeline.


Product features


  • Good general corrosion resistance and high strength
  • Good sulfide stress corrosion resistance
  • Resistance to chloride pitting and crevice corrosion
  • Higher resistance to chloride stress corrosion cracking
  • Easy to weld and conform


Equal Tee VS Reducing Tee


  • Steel Equal Tee pipe fittings: The three branches of tee have same diameters.
  • Steel Reducing Tee: The branch diameter is smaller than the main line diameter. Tee reducer is usually described as NPS diameters in 4”x 4”x 3”, 4”is the main line pipe diameter, and 3”is the reducing branch.


Stainless steel and Galvanized


Steel is galvanized to prevent corrosion,while stainless steel is inherently resistant to corrosion.Galvanized is more ductile and easier to machine; stainless steel is stronger and more resistant to corrosion.In addition,Galvanized design life always be 20 years,but there is 50 years for stainless.Therefore,stainless is more expensive by its superior properties.
