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.

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.

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:
  • 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 Socket Weld Equal Tee are pipe fittings that be formed mainly by forging.
