How to get high quality pipe tees?

What is a pipe tee?

Pipe Tee is a type of pipe fitting which is T-shaped having two outlets, at 90° to the connection to the main line. It is a short piece of pipe with a lateral outlet. Pipe Tee is used to connect pipelines with a pipe at a right angle with the line. Pipe Tees are widely used as pipe fittings. They are made of various materials and available in various sizes and finishes. Pipe tees are extensively used in pipeline networks to transport two-phase fluid mixtures.

Using a pipe tee, a plumber is able to combine the flow of two separate pipes into a single line. He may also divide a single supply line so that it flows to two different areas. For example, a pipe tee can be used at the main water supply line in a home to direct some water to the bathroom and some to the kitchen. It may also be used in the home’s wastewater system, where it joins two separate sewer lines into a single main drain line that can tie into a municipal drainage pipe. In industrial applications, a pipe tee can join two pipes carrying different liquids, which blends the two materials into a single stream as they flow to their final destination. Pipe tees can connect pipes of different diameters or change the direction of a pipe run, or both. Available in a variety of materials, sizes and finishes, they may also be used to transport two-fluid mixtures.

Standards

  • ASME B 16.9 for large bore
  • ASME B 16.11 for small bore

Types of pipe tees:

Reducing tee

Reducing tee is widely used in various commercial and industrial applications.

Equal tee

Equre tee (or straight tee), means the branch diameter of this tee is same with the main pipe (Run pipe) diameter of this tee.

Barred Tee

Barred tees are pipe fittings with two outlets, one at 90 ° to the connection to the main line that has tiny holes.

Lateral Tee

A Lateral tee is one kind of tee fittings, which has a 45 degree branch from a pipeline: (45° Lateral Tee). It is a kind of steel pipe tee, but the branch direction is different with the straight tee. On the contrary to the lateral tee,the straight tee has a branch pipe direction of 90 degree to the run pipe.  

Type of the lateral pipe fittings:

Lateral pipe fittings have two types: lateral tee and latrolet (also called Lateral Outlet).

The lateral tee’s shape is like a pipe tee, the butt welding lateral tees are made from steel pipes or forgings, the manufacturing standard is ASME B16.9. there are also the forged lateral tee produced refer to ASME B16.11,the ends are socket welding and threaded.
