What is a Butt Welding Tee?

CompariTee welding joints are formed when two pieces intersect at a 90° angle. This results in the edges coming together in the center of a plate or component in a ‘T’ shape. Tee joints are considered to be a type of fillet weld, and they can also be formed when a tube or pipe is welded onto a base plate.

Advantages of Butt Welding Tee

Comparing to other types of steel pipe fittings,butt welding pipe fittings has advantages:

1.Butt welding joint is permanently leakproof and strong.

2.Continuous steel structure of the joints between the pipes and fittings have a good strength in the piping system.

3.The butt welding pipe fittings commonly have a smooth surface and gradual directional changes,it will decrease the pressure losses and turblence of the system,and protect from the corrosion and erosion.

4.The butt welding pipe fittings have a lower cost in bugdet.

5.The butt welding joints have a smaller space in the system.
