]]> Our Carbon Steel Tee is highly appreciated by customers for its superior quality and optimum finish. It is available in socket weld, butt weld and screwed. We can also fabricated other form according to the demands of the customers.

A pipe tee is also called triplet,three way and “T” pieces and it can be used to either combine or split a fluid flow. There are two types that equal tee and reducing tee.

Equal Tee vs Reducing Tee

Reducing Tee vs Equal Tee

Reducing Tee vs Equal Tee

Equal tee has same inlet and outlet sizes, but reducing tees has the one or two ends different in dimension. Due to this, that makes the tee fittings with the capacity to control the volume when required.

  1. The even thickness around the socket bore shall not be less than the average value, the thickness at partial areas can be the min one.
  2. Considering the tolerance of outside diameter of pipe, the diameters of some socket bore can be a little larger than the ones specified in B16.11
  3. When the sizes of the connecting pipes are not conformed to the ones specified in this catalog, the sizes of the connecting pipes shall be provided in the purchase specification.

Socket Weld Equal Tee

The branch diameter is same as run pipe diameter. So we also call it as straight tee. They are widely used in the small piping system.

Socket Weld Reducing Tee

As the other reducing pipe fittings, reducing tee has the different diameter for the ends. So they can change fluid direction, speed and volume.

What is Socket Weld?

A Socket Weld is a pipe attachment detail in which a pipe is inserted into a recessed area of a valve, fitting or flange. In contrast to buttweld fittings, they are not need to do beveling for welding preparation and have lower construction cost.

Equal Tee VS Reducing Tee

Both of Them are available in butt weld, socket weld and threaded types. Equal Tee is also called straight tee, it means three branches are same. Reducing tee means the branch diameter is smaller than run pipe diameter.  For example, when describe it as reducing tee 2″ x 1″ NPT Class 3000 ASME B16.11, that means the run pipe diameter is 2″ and branch diameter is 1″.

Package of NPT Pipe Fittings

We marked Stainless Steel Equal Tee as ” 3/4″ 6000# NPT A182 F316 168″. The workers sleeved 3/4″ NPT Tee SS 316 into plastic bag individually, put all of them into cartons and wooden cases, then bundled package with nylon rope.

Clear labels are tagged on the outside of the package for easy identification of the quantity and product. Great care is taken during operation and transportation.

How to Inspect Threaded Equal Tee

  1. Visual the surface. Such as dents, die marks, porosity, undercuts.
  2. Check the marking. Such as size, material grade, pressure, thread type, heat No.
  3. Measure dimensions. Such as outside diameter, thread length, height from end to end.
  4. Test the chemical composition of stainless steel threaded tee.
  5. Test the thread by go/no gauge

Package 

Butt Weld Tees Package

Butt Weld Tees Package

We marked all ASME B16.9 Buttweld Fittings with Type, Grade, Lot No, Size, Standard and Thickness. Our workers packed ASTM A815 WP-S UNS S31803 BW Equal Tee into wooden pallets or cases. We use anti-rust oil and plastic bag to protect duplex steel fittings to against rust during shipping.

Clear labels are tagged on the outside of the package for easy identification of the quantity and product I.D. Great care is taken during operation and transportation.

Inspection 

Visual the surface of buttweld Tee body.

Check the marking ” 12″ SCH60 TEE EQUAL ASTM A815 UNS S31803 ASME B16.9 Z188″

Measure outside diameter, wall thickness, center to end and end to end.

Test the chemical properties of duplex stainless steel buttweld equal tee.

Duplex Stainless Steel Features

  • High strength
  • High ductility
  • Outstanding corrosion-resistant

UNS S31803 Temperature Range

Duplex Stainless Steel UNS S31803 Fitting also known as duplex 2205 fitting. Its temperature range typically is -50° to 300° C (-58° to 572° F); outside of this range, its performance characteristics degrade.
