Stainless reducers

Stainless steel reducers are applied, to change the pipe size from one pipe diameter to another. Standard there are 2 possibilities, a stainless concentric reducer,  which is usually used in vertical pipe lines, and the eccentric stainless reducer that is used in horizontal pipe lines. The length of the stainless reducers is very short in relation to the diameter, so in some dimensions the transition from one to another diameter is very abruptly. 

Eccentric stainless reducer couplings connect two pipes of different sizes that are not along the same pipe axis. This coupling has butt-weld, beveled openings for welding pipes together. Made of stainless steel 304L, 316L or other stainless alloys, the lower carbon content of the eccentric reducing coupling minimizes harmful carbide precipitation during welding, ensuring corrosion resistance. 

A stainless concentric reducer is used to join pipe sections or tube sections on the same axis. The concentric reducer is cone-shaped, and is used when there is a shift in diameter between pipes. This pipe reducer may be used when there is a single diameter change or multiple diameter changes. Unlike eccentric reducers, concentric reducers have a common center line. Concentric reducers are useful when cavitation is present. 

We only supply fittings from TÜV and PED-approved manufacturers with EN 10204-3.1 or 3.2 TÜV acceptance test certificate in accordance with the applicable AD (working group for pressure vessels in Germany) specification sheets.

Stainless Concentric reducer - welded  Butt welding stainless reducers are used to decrease or increase the pipeline size at a given location. With regards to the Welded Concentric reducers, the open ends of the fittings are aligned and centered one to the other. Generally, the delta in size doesn't exceed the 2 (max 3) sizes to avoid an exc..

Stainless Eccentric reducer - welded

Stainless Concentric reducer - welded  These eccentric reducers have a shape wherein one side is symmetrical to the source stream and the other side is slanted. These are used between two pipes to reduce the flow of fluid or gas into and out of a pump. Eccentric reducer can also be used inversely to increase the flow of the substance. Our..
