Pipe Fitting Manufacturer Changrun Supplies Concentric Reducer and Eccentric Reducer,
Type: Ecc Reducer
Size: 610x31mm-426x20mm
Wall Thickness: 31MM, 20MM
Material: ASTM A 234 WPL6
Standard: ANSI B16.9.
End Connection: Butt Weld
Certificates: CE, ISO, PED, TS, BV, CQC.
There are two types of reducers: concentric reducers and eccentric reducers. The shape of the eccentric reducer is asymmetric, and the centers of the two ends are offset from each other. This design allows for gradual transitions between pipes of different diameters, while changing the elevation or position of the pipes. Eccentric reducers are usually used in situations where vertical or horizontal adjustment of the pipeline is required to ensure optimal flow rate. They can be applied in industries such as oil and gas pipelines, sewage treatment, chemical manufacturing, and wastewater management.
Butt Weld Reducers
Concentric and Eccentric ASME B16.9
Dimensions are in millimeters unless otherwise indicated. Wall thickness (t) must be specified by customer.
