What is a barred tee?

Barred tee is a pipe fitting that is used in a pig launcher or receiver system in a piping system to ensure the pig could pass the branch safely.

How to design and produce the barred tee?

The shape of a barred tee is like a butt welding pipe tee with some bars in the branch of the tee.The bars are used for preventing the pig from
running out in the branch of the main pipe.It is commonly used in a pigged pipeline,so it is also called pigged tee.

The bars in the branch should be installed flush with the inside diameter of main pipe.Commonly the bars are welded with the tees.
