The non-concentric sewage conversion connection is manufactured according to the following standards:
INSO 9119-1 and EN 1329-1
An eccentric reducer is designed for situations where a change in pipe size is required in a building’s sewage system. In these circumstances, reducer fittings are used. This fitting acts like a connector between two different sizes, allowing pipes of different sizes to be connected without creating leaks of fluid or waste in the sewage discharge system.
Features of Eccentric Reducers
The eccentric reducer has features that have made it one of the most widely used fittings in the piping industry.
1. Eccentric Design
Here, we want to address the most important feature of this product, as this feature is repeated multiple times later in the text, and it’s best to understand the meaning of eccentric design. In the design of this piece, an effort is made to place the center axis of the larger end on a line with the center axis of the smaller end, but with a slight difference. This is why it is called an eccentric reducer. This design creates a step or level difference.
2. Suitable for Horizontal Piping
The eccentric reducer is mostly used in horizontal piping because this reducer helps to level the pipes and prevents condensation in the pipes, especially in the curved sections.
3. Prevents Corrosion and Liquid Accumulation
We mentioned earlier that the eccentric reducer prevents the accumulation of steam and moisture in the pipes. This feature has a direct impact on keeping the pipes healthy and preventing their corrosion due to moisture.
4. Prevents Reduction of Fluid Pressure
By gradually changing the pipe size, the eccentric reducer is very useful in minimizing disruption to the flow of fluids and prevents pressure build-up caused by the change in size.
Types of Eccentric Reducer Production Methods
There are 4 common methods for producing this product, which we will discuss below:
Casting
Hot rolling and forming
Cold forming
Welding of parts
This product has one female end (one socket end) and one male end.
9119 sewage fittings, manufactured by Oraman Gharb company, will be delivered to dear consumers in white color and in cartons.
