A barred tee is a tee or any fitting with a branch used in pipelines that is pigged and has a restriction bar welded internally preventing the pig from traveling down a branch connection.
Barred Tee for long distance submarine oil and gas pipeline.
Datasheet of a pipe barred tee
Barred tees are pipe fittings with two outlets, one at 90 ° to the connection to the main line that has tiny holes. Barred tees can either be extruded or fabricated and are used to connect two pieces of pipe or fittings. Barred tee is used in pipelines that are pigged.
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.
· Reducing tee is a type of pipe fitting in which the branch port size is smaller than the ports of the run.
· Barred tee is used in pipelines that are pigged.
· Lateral tee has a 45 degree branch from a pipeline.
· Pipe cross is a fitting that used in the place where four pipes meet with the same diameter include:
o 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.
o 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.

Features of Pipe Tee:
· There are three female openings in a T shaped pipe tee.
· There are straight pipe tees which have the same size openings.
· Reducing pipe tees have one opening of different size and two openings of the same size.
· There are sanitary pipe tees which are used in waste lines. These kind of pipe tees have a curved branch which is designed for a clean out plug. They are used to prevent obstruction of waste.
· A cross pipe tee has four equal sized female openings.
· A wing pipe tee has lugs to fasten the fitting to a wall or stud.
· A compression pipe tee uses compression fittings on two or more ends.
· A test pipe tee has a threaded opening. This opening is used in conjunction with a threaded plug for a clean-out opening on a drain pipe.
