Bangdong is great manufacture of butt weld tee .  If you require Carbon Steel BW Tee , Alloy Steel BW Tee , Stainless Steel BW Tee , Special Tee welcome to contact us freely , we have drawings and datasheets for your reference .

Buttweld pipe fittings comprises of long radius elbow, concentric reducer, eccentric reducers and Tees.They are an important part of industrial piping system to change direction, branch off or to mechanically join equipment to the system. Buttweld fittings are sold in nominal pipe sizes with specified pipe schedule. BW fitting`s dimensions and tolerances are defined as per ASME standard B16.9.

Common types of pipe tee

A pipe tee is a type of fitting that has a T shape and is used to join two or more plumbing pipes.

Equre tee (or straight tee), means the branch diameter of this tee is same with the main pipe (Run pipe) diameter of this tee.Butt weld pipe Tee allows a 90 degree branch off from a running pipe.This allows for connecting auxiliary equipment to a pipe. A tee is welded on both side to the pipe, leaving the branch open for branch off. 

Reducing tee is a type of pipe fitting in which the branch port size is smaller than the ports of the run. Butt weld reducing tee has a branch that is smaller than main run. This allows for branching off to a smaller pipe of equipment from the main run. 

Barred tee is used in pipelines that are pigged. Barred tees , weld bars on branch end , the bars could be specially designed .

Lateral tee has a 45 degree branch from a pipeline. Y tee also available .

Pipe cross is a fitting that used in the place where four pipes meet with the same diameter include:

Reducing cross used for connecting four pipes, the main pipes with the same size, but the dimensions of the branch diameter is smaller than the main pipes.

Equal cross in the place where four pipes meet with the same diameter.

Forged Tee Fittings are pipe fittings that be formed mainly by forging.
