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 Tee Fittings are pipe fittings that be formed mainly by forging.

Size range: 1/2 to 72 inches

Pressure: SCH5 to SCH160


What is ASTM A234 WP91?

There are different standards and specifications involved. There are three major standards to cover major groups of nominal sizes. The range from 1/3 to 4 inches is governed by B16.11 standard where the B16.5 covers up to 24 inches, the B16.9 covers up to 48 inches and the B16.47 covers nominal sizes of up to 60 inches. There are also pressure classes such as 300, 600 and so on which govern the pressure containment capacities of the ASTM A234 WP91 Fittings made pipe fittings. It is not always necessary to use the A234 WP91 material made fittings in piping. Sometimes, an A234 WP91 Equivalent could be used to replace it depending on the requirement of the application. The fittings withstand high temperatures and pressures.

The standard specification for A234 WP91 covers both fittings that have been constructed with both seamless as well as welded construction. In the term A234 WP91, WP91 is known as one of the steel grades in this particular standard where W means weldable, while P stands for pressure and the number 91 is referred to as grade 91.

 

There are various kinds of forging or shaping operations that can be performed on the Alloy Steel Grade WP91 Fittings. Generally, processes such as treating these fittings by hammering, upsetting, rolling, bending, pressing, piercing, extruding, fusion welding, machining can be practised either individually or by using a combination of two or more of these processes to forge or shape these ASTM A234 Gr WP91 Fittings. The forming procedure must be practised such that it must not allow for the formation of any injurious imperfections in the fittings. In order to prevent injurious defects that could be caused by too rapid cooling, Fittings such as the ASTM A234 Grade WP91 Elbow, must be allowed to be cooled at a temperature range that is below the critical range under suitable conditions after forming them at an elevated temperature. Although special care is to be taken that the rate of cooling these A234 WP91 Equivalent is not more rapid as compared to the rate of cooling while still in the air.
