Socket weld tee is a high pressure pipe fitting in three ways which made by forging from round steel. They are in T-shaped and know as equal tee and reducing tee. It is generally applicable to pipes with nominal diameter less than NPS 2.
Socket Weld Fittings are a family of high pressure forging fittings that used only in conjunction with ANSI Pipe and are available in the same size range.
Even though there are some similarities between the shapes of the two welds, but socket weld is still considered to be different from a fillet weld.

Advantages of Socket Weld Tee
The socket connection method of the socket weld tee is relatively simple. When installing, just insert the branch pipe into the socket and then perform the sealing operation. Compared with the welded tee, it does not require complex welding equipment and professional welding skills.
The socket weld tee usually adopts sealing methods such as rubber sealing rings. When the branch pipe is inserted into the socket, the rubber sealing ring is compressed and filled in the gap of the socket interface, thereby effectively preventing the leakage of the medium in the pipeline.
The socket connection method makes the branch pipe and the main pipeline form a more stable connection. During the operation of the pipeline system, it can withstand certain pressure and vibration.
