What is barred tee for pipeline?
Barred Tee is a special type of Tee that base from a normal tee (can be either equal tee or reducing tee) that at later stage, will be added with bar plates inside the branch outlet (From inside it looks like a steel cage) to restrict the pig from flowing from the header pipe into the branch pipes.
Why We Use 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.
What is a pigging tee?
A barred tee (pigged 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 tees are pipe fittings with two outlets, one at 90 ° to the connection to the main line that has tiny holes.
What is a reducing tee?
Reducing tee is another type of pipe tee used in pipe and tube fittings. Reducing tee, like all pipe tees, is in the shape of T with two ends of equal size and the third one slightly smaller. In other words, reducing tee is a type of pipe fitting in which the branch port size is smaller than the ports of the run.
What is a split tee fitting?
It is a pipeline fitting designed such that the inner diameter of the fitting is the same size as the outside diameter of the pipe that will be hot tapped. As a rule of thumb, a split tee is used when the branch connection is equal to or greater than half the diameter of the run direction.
What is Flow tee?
A Flow Tee is a special fitting that is mainly used in pipeline pigs past tee connections – where flow bypass often leaving pigs stranded without restricting product flow. The Flow tees can be barred or sphere.
What is a lateral fitting?
A lateral pipe tee means a pipe fitting which is similar to a tee but has a side opening outlet branch at a 45 degree angle. It is a kind of steel pipe tee,but the branch direction is different with the straight tee.
How do you read a reducing tee?
For example if a Tee is 3/4″ X 3/4″ X 1/2″, then the left inside diameter is 3/4″, the right inside diameter is 3/4″ and the top inside diameter part is 1/2″. Tees where the run and the bull are not uniform are referred to as “Reducing Tees”.
What is the difference between equal tee and unequal tee reducing tee?
The equal tee (or straight tee) is used as the branch has the same diameter as the run-pipe. The reducing tee is used as the branch has a smaller diameter as the run-pipe.

What is the difference between a wye and a lateral?
A straight run with a branch to one side is a LATERAL. A fitting with a trunk coming up that splits to a 45º branch left and right is called a TRUE WYE, because it resembles a “capital letter Y” as we learned to draw it in grade school.
What is a barred tees used for?
Barred Tees are used in a pipeline Launcher/Receiver system and at any branch in the pipeline to ensure safe passage of the Pig. Manufacturer reserves the right to modify dimensions, materials, or design. Consult factory for certification. For a full page, printable version of this information, please click on the PDF icon.
Can You Weld a barred Tees?
Bar ends must be machined to fit the branch. Weld Repairs on Parent metal is prohibited. 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.
Why choose suresure flow barred Tees?
Sure Flow Barred Tees are manufactured to specific customer project specifications in a full range of sizes from ASME Class 150 to 2500 and higher. They are fabricated to the highest industry standards and pipeline vessel design codes in Carbon Steel, Stainless Steel or Alloy materials.
What is a Teetee fitting?
Tee is a type of fittings that allows fluid to flow on its main pipe and branch out. The branch can be designed equally the same size as the main pipe (known as Equal Tee), or smaller size than the main pipe (known as Reducing Tee).
