The 90 degree three-way sewage coupler is manufactured according to the following standards
INSO 9119-1 and EN 1329-1
The 90-Degree Reducing Wye with Three Coupled Ends is used when a change in pipe size is required in a building’s sewage system. In such cases, the group of reducing fittings is used. This fitting operates between two different sizes, at a 90-degree branch angle, and ensures that the pipe size change is executed without causing any fluid or waste leakage, and that the components of the sewage drainage system are completely connected to each other
Features of the 90-Degree Reducing Wye with Three Coupled Ends
The main application of this 90-degree reducing wye with three coupled ends is a 90-degree change in direction and its connection to the main pipe, which makes this product highly useful in building plumbing and sewage systems. The 90-degree Reducing Wye with Three Coupled Ends has three coupled (threaded) ends, which facilitates connection and branching to the main pipe. This wye also has different applications depending on the material used in its construction, such as PVC (Polika), polyethylene, or metal. One of the most common materials used to make this wye is polyethylene, which is suitable for plumbing in residential buildings due to its resistance to corrosion and detergents. The 90-degree Reducing Wye with Three Coupled Ends made of metal is also widely used for industrial plumbing due to its high-pressure tolerance
Differences and Similarities Between the Reducing Wye and the Regular 90-Degree Wye (Both with Three Coupled Ends)
Differences: In the regular 90-degree wye with three coupled ends, all three ends have the same size, and a size change is only possible by using an Non-concentric transformation. However, in the reducing wye, one end has a different size, which allows the pipe diameter in the plumbing system to be changed. Also, the application of these two types of wyes differs; the regular 90-degree wye with three coupled ends is suitable for systems with a constant diameter, while the 90-degree reducing wye with three coupled ends offers more flexibility for changing the diameter along the pipe path.
Similarities: The overall design of both types of wyes is almost similar, and both have three coupled ends. The manufacturing material is also considered the same, depending on the application.
