Description

ASME/ANSI B16.9 A234 Carbon Steel Seamless Butt-Weld Pipe Reducer Manufacturer

　　A pipe fitting reducer is used for connecting two different pipe diameters. It is further divided into concentric pipe fitting reducer and eccentric pipe fitting reducer.

　 Concentric Reducer

　　Concentric reducer is also called welded concentric coupling. It allows from connecting a large pipe to a smaller pipe by means of welding. A concentric reducer allows welded connection between two pipes with the same center line.In concentric reducers the area reduction is concentric and the center line of the pipe on a bigger end and smaller end remains the same. These styles are normally used for vertical lines. So in concentric reducers, the pipe axis remains the same. Reducers are reversible and can be used in any direction.

　　Eccentric Reducer

　　Eccentric reducer is a fitting used in piping systems between two pipes of different diameters. The same fitting can be used in reverse as an eccentric increaser or expander. They are used where the diameter of the pipe on the upstream side of the fitting (i.e. where flow is coming from) is larger than the downstream side, and where there is a danger that vapor may accumulate. In Eccentric Reducer the reduction of the pipe size is achieved by decreasing the diameter of the fitting at a constant rate over a specified length, maintaining one side of the fitting horizontally.

Workshop

Packaging & Transportation

The production process of carbon steel reducers mainly includes the following methods:

　　‌Reduction forming‌: Put a tube blank with the same diameter as the large end of the reducer into the forming die, and press along the axial direction of the tube blank to make the metal move along the die cavity and shrink to form. According to the size of the diameter change of the reducer, it is divided into one-time pressing forming or multiple pressing forming‌.

　　‌Expansion forming‌: Use a tube blank with a diameter smaller than the large end of the reducer, and use an internal punch die to expand the inner diameter of the tube blank. The expansion process mainly solves the problem that the reducer with a large diameter change is not easy to be formed by reduction. Sometimes, according to the needs of material and product forming, the expansion and reduction methods are combined.

　　‌Stamping forming: For some specifications of reducers, steel plate stamping forming process can be used for production. The shape of the die used for stretching is designed with reference to the inner surface size of the reducer, and the steel plate after cutting is stamped and stretched by the die.
