Reducing elbow: 3''X2'' STD WPB Beveled ASME B16.9


Reducer (reducer) is a kind of pipe fitting used in the pipe reducing position.

The commonly used forming processes are necking pressing, expanding pressing or reducing plus expanding pressing. For some sizes of reducers, stamping can also be used. The reducing process of reducing / expanding reducing pipe is to put the tube blank with the same diameter as the big end of the reducing pipe into the forming die, and the metal moves along the die cavity and shrinks to form by pressing along the tube blank axial direction. According to the size of reducer, it can be divided into one-time pressing forming or multiple pressing forming.


ASME B16.9 Reducers are known to deliver exceptional performance and are generally developed for meeting the demands. We offer a broad range of butt welding reducer through a worldwide network of stock-keeping branches.These Pipe reducers are used in various industries like:

>Stainless steel butt welding reducer uses in Oil and Gas Pipeline

>Butt welding reducer uses in Chemical industry

>Alloy Steel reducer uses in Plumbing

>Butt welding reducer Fittings use in Water Supply Systems

>ANSI B16.9 Butt welding reducer uses in Power Plant

>Butt welding reducer uses in Fabrication Industry

>Butt welding reducer uses in Structural Pipe
