What is a Butt Weld Tee
Butt weld tee fittings have the same diameter vacuum tubing on all three ports. Tees are a common component of vacuum piping systems and are used to provide a 90 degree branch. Butt weld tee fittings for branching. 304 Stainless Steel construction.
8" SCH40 on pipe tee fittings means that it can hold 40 kg of pressure. It's shown by a standard diameter is 219.1 mm, thickness is 8.18 mm. The most common pipe schedule is Schedule 40 Steel Pipe Tee. It can be galvanised, but it doesn't have to be, and is usually used for water and gas lines.
8" SCH40 utt weld tee is widely used in petroleum, chemical industry, power plant and other industrial pipelines. The common used material are carbon steel A234 WPB and stainless steel 316.

Types of Butt Weld Pipe Fittings
Welded pipe fittings in carbon steel and stainless steel are the joining components that make possible the assembly of valves, pipes and equipment onto the piping system. Welded fittings compliment pipe flanges in any piping system and allows:
Change direction of flow in a piping system
Connect or joint pipes and equipment
Provide branches, access and takeoffs for auxiliary equipment
A common example using welded pipe fitting is a pipe reduced by concentric reducer, welded to a weld neck flange and connected to equipment. The figure below represents a complete collection of butt welded pipe fittings.
Types of Butt Weld Tee
Steel pipe tee
Steel tee is a T-shaped pipe fitting with three branch pipes. It is used to divide pipes to adjust flow and change direction.
Equal Tee
Equal diameter tee, also known as straight tee, the branch diameter of the tee is the same as the pipe diameter of the tee.
Reducing Tee
The reducing tee has two outlets cut at 90 degrees with the main pipe, and the size of the branch pipe is smaller than the port of the pipeline
Material of Carbon Steel Butt Weld Tee
A234 WPB is the most common material used for carbon steel butt welded Tee fittings. ASTM A234 WPB is the Standard Specification for Piping Fittings of Wrought Carbon Steel and Alloy Steel for Moderate and High Temperature Service.

Benefits of 8" SCH40 Butt Weld Te
1. Welded connection offers a more robust connection
2. Continuous metal structure adds to the strength of the piping system
3. Cost effective compared to their expensive threaded or socket weld counter parts
4. Stainless Steel Welded Fittings are also available in SCH 10, allowing a more thinner wall option
5. Stainless Steel Butt Weld Fittings are more common in SCH 10 and SCH 40 configuration
