Thick Wall Weldable 304 Stainless Steel Tube Concentric Reducers Fittings

A Stainless Steel Tube Concentric Reducer is a pipe fitting that consists of two pipes of different diameters, and the central axes of the two pipes are exactly the same, so it is called a concentric reducer and is used to connect pipes of different sizes.

Stainless steel concentric reducers are composed of a pipe with a large outer diameter and a smooth outer surface and a pipe with a small inner diameter. The ports of the two pipes are completely aligned and fixed together by welding, sockets, or threaded connections. This structure allows the concentric reducer to smoothly transfer fluid in the piping system and reduce the resistance and pressure of the fluid.

Concentric reducers are also made of stainless steel, such as 304 stainless steel or 316 stainless steel. Because stainless steel has corrosion resistance and high-temperature resistance, it is suitable for the transmission and control of a variety of media. Choosing the right stainless steel material ensures the durability and reliability of your piping system.

Concentric reducing pipe fittings are usually used in engineering fields such as waterproofing and enhanced protection. The advantages are stable connection, good sealing, and the ability to withstand large flow rates. It is also often used in the field of hydropower engineering in construction. For example, in a bathroom drainage system, in order to connect drainage pipes of different diameters, it is necessary to use concentric reducing pipe fittings to connect the downpipe and the drain pipe.
