Why do reinforcing tee?

Are you worried about the thickness of the shoulder wall of the tee?

I believe many customers have encountered similar problems.Let’s discuss it together.

The tee is an important part in the pipeline system, and the welded tee is widely used in petrochemical and industrial large-diameter pipeline because of its advantages such as light structure and low cost.

Reinforcing Tee

Due to the irregular structure of the tee, the main pipe and the branch pipe are connected, which is equivalent to opening a hole in the cylinder, which makes its stress distribution more complicated. The tees are mostly located at the supports such as the redirection of the pipeline and the flow diversion,and become the concentrated parts of the pipeline load. Therefore,they are not only subjected to internal pressure,but also often subject to bending moments and torques. At the same time,the thinning caused by the erosion of the tee wall by the high flow rate medium and the pits caused by the corrosion of the pipe wall by the corrosive medium increase the opportunities for cracks, local bulging,leaks,and blasting. In a sense, the tee quality and the level of the bearing capacity will directly affect the integrity and safe operation of the entire pipeline system.

Therefore, the ASME B31.3 standard makes reinforcement requirements for tees, extruded outlets, laterals and branch outlet fittings in accordance with MSS SP-97. How to reinforce it? Later articles will give you an answer.
