Steel pipe fittings have a common type that is called a tee. A tee has three branches that change the direction of the material it is carrying. There are different kinds of tees. There are Y shaped tees and T shaped tees. Also, the amount of flow can be changed through a tee. There are equal tees and reducer tees. Steel is a very common material for pipe fittings and tee is no different. You will also find stainless steel tee and carbon steel tee in the market. According to shape, welding process, size and materials tees can be of different types.

According to Shape

According to shape tees can be of two types.

Y Shape: Y shape tees are also tees but the third connection is placed in a different angle. The two connections are common which carry the flow in the same direction. But the third connection that flows in sideways is placed usually at a 45-60 degree angle on Y shaped tee rather than being a 90-degree angle like the T shaped Tee.

T Shape: T shape tees are very common and the name came from this shape. The third connection is placed at a 90-degree angle. This is the reason it looks like a T and is called a T shaped tee.
According to Size

According to size, there are some tees.

Equal Tee: Equal tees are designed to carry the same amount of flow in every direction. Here, all three connections are same in size. The bore size of the pipes connected and the tee openi9ngs are same in all three sides.

Reducer Tee: In reducer tee, the openings are not same in size. Some tees have one reduced opening and some have two. It reduces the flow. For example, if two of the openings are reduced to ¾ or ½ of the actual size, it will help to distribute the flow evenly.

According to Materials

There are different materials used for tee fittings. The most common ones are described below.
Steel: Steel has been one of the most popular elements for pipe fittings for decades. It is no different for tees. Steel tees can last for years and are used widely in the world.

Stainless Steel: Stainless steel tees are used to places where stains are not appreciated. Stainless steel does not catch rust and therefore is very good pipe fittings. It does not catch dirt from the transport system.

Carbon Steel: Carbon steel is an upgrade from stainless steel. It does not catch rust and can take extreme pressure and temperature. So for carrying hot chemicals, gas or water people choose carbon steel pipes and fittings.
PVC: In recent times PVC has been used for pipes and fittings. It is good enough for household purposes for several years but some people do not advise using plastic for their utility delivery channel. Also, PVC cannot take the pressure and high temperature which limits its use to only households.
