Straight Tee (Equal Tee)

An equal tee, otherwise called straight tee, means the branch diameter of this tee is same with the main pipe (Run pipe) diameter of this tee.
A pipe tee is defined “equal” when the bore size at the run and branch sides have the same diameter. An equal tee is, therefore, used to connect two pipes of the same nominal diameter.
Equal tees are available in sizes from half an inch to 48 inches (or larger) and in seamless and welded execution (seamless up to 24 inches, welded for tee sizes above 24 inches).

The equivalent tee (or straight tee) is utilised as the branch has the same distance across as the run pipe. Equal Tee are equipped for taking care of any high or low weight stream of fluid through it. The equal tee are with the same channel and outlet sizes, however, customers can profit from us “decreasing” tees too that have maybe a couple closes with various in measurement, this is called an equal tee. Because of their dimensional contrast, these tee fittings help with the ability to control the volume when required. Our scope of Equal Tee and Equal Cross are impeccably built utilising most recent innovation and are generally utilised as a part of differing piping frameworks crosswise over commercial ventures. Faultlessly built to flawlessness utilising most recent machines and innovation, these pipe fittings are broadly utilised as a part of a large number of commercial ventures far and wide. Durable in quality, these pipe fittings are accessible at competitive prices.

Features Of Equal Tee

There are three female openings in a ‘T’ formed pipe tee.
There are straight pipe tees which have the same size openings.
Equal tee make them open of various size and two openings of the same size.
There are sterile equal tees which are utilised as a part of waste lines.
These sort of equal tees have a bent branch which is intended for a wipe outfitting. They are utilised to avoid hindrance of waste.
An equal tee has dragged to attach the fitting to a divider or stud.
An equal tee utilises pressure fittings on two or more finishes.
An equal tee has a strong opening. This opening is utilised as a part of conjunction with a strong fitting for a get out an opening on a drain pipe.

Pipe Tee Manufacturing Process

Cold forming is the most used manufacturing process for seamless buttweld tees, as illustrated below. Other methods are the single, Hot Forming or double seam welding process.

Note:
MSS SP-43 only covers stainless steel buttweld fittings made for use with Schedule 5S and 10S pipe and Stub Ends suitable for use with Schedule 40S pipe, as defined in ASME B36.19. The dimensions and dimensional tolerances defined in MSS SP-43 are substantially the same as those in ASME B16.9 specifications from NPS 1/2 – NPS 24. Except with regard to the outside diameter at the bevel.
