What is a Buttweld Equal Tee?

In the complex world of industrial piping, the Buttweld Equal Tee (commonly referred to as a Straight Tee) stands as one of the most vital components for managing fluid distribution. This fitting is engineered to create a 90-degree branch from a main pipeline, facilitating a seamless connection between horizontal and vertical runs.

Defining the “Equal” in Equal Tee

The term “Equal” signifies the dimensional symmetry of the fitting. In an Equal Tee, the diameter of the branch outlet is identical to the diameter of the main run pipe. Unlike reducing tees, which transition to a smaller pipe size, the Equal Tee maintains a consistent bore throughout all three openings. This uniformity is critical for systems requiring stable pressure and flow rates across different directions.

We deliver Seamless Buttweld Equal Tees in the following material grades:

Carbon steel	A234 WPBA420, WPL6A234, WP5/WP11/WP22
Stainless steel	A403 WP316L,A403 WP304L,A403, F321H, F51(Duplex) / F53(Superduplex)
Alloys Steel	Hastelloy C276/C22

Buttweld Equal Tee Characteristics:

buttweld seamless Equal Tee

1. Identical Diameters: In an equal tee, the branch diameter is the same as the main pipe diameter.
2. Three Outlets: It features three openings arranged in a ‘T’ shape.
3. Uniform Openings: All three openings are of the same size.
4. Pressure Fittings: Equal tees often utilize pressure fittings on two or more ends.
5. Strong Opening: They are designed with a robust opening, which can be used with a strong fitting to create an access point on a drain pipe.

Reducing Tee Characteristics:

1. T-Shaped with Varied Outlets: A reducing tee is a T-shaped pipe fitting with two outlets cut at a 90-degree angle to the main line. It offers a combination of different outlet sizes.
2. Mixed Opening Sizes: These tees feature openings of various sizes, with two openings typically being the same size.
3. Mounting Capability: Reducing tees can be securely attached to a wall or stud.
4. Pressure Fittings: Similar to equal tees, they often incorporate pressure fittings on two or more ends.
5. Robust Access Point: A reducing tee also includes a strong opening that, when combined with a suitable fitting, can serve as an access point on a drain pipe.
