Specification of reducing joint

The specifications of reducing joints are usually expressed in diameter dimensions, for example, DN50 × DN32 represents connecting pipes with diameters of 50 millimeters and 32 millimeters. The specific specification range is as follows:
Common specifications
Concentric reducing joint: suitable for liquid pipelines, with specifications ranging from 3/4 “to 48”, and some standards covering DN10-DN150 or 1/2 “-6”. ‌
Eccentric reducing joint: suitable for gas pipelines, with specifications consistent with concentric joints. ‌
Material and Application
Stainless steel reducer: made of materials such as 304 stainless steel and 316 stainless steel, commonly used in industrial pipeline systems.
Plastic reducing joint: made of materials such as PVC and PE, suitable for variable diameter connection of water supply pipelines. ‌
Special specifications
Rubber reducing joint: supports flange and threaded connections, with working pressure levels of 0.25/0.6/1.0/1.6/2.5MPa and a working temperature range of -15 ℃ to 120 ℃ (special types can reach -30 ℃ to 250 ℃). ‌
