Stainless steel concentric reducers are pipe fittings with different diameters at both ends, and their centers are on the same straight line. They are mainly used to connect pipes of different sizes to achieve flow control or space optimization.
Structural Features
Center Position: The centers of the diameters at both ends are on the same center line, presenting a conical structure.
Application Scenarios: Suitable for wall or floor-mounted pipe laying, saving space; commonly used for fluid flow control or pressure regulation.
Material and Standards
Common Materials: 304/316L stainless steel, carbon steel, etc.
Production Standards: Comply with American standard ANSI/ASME B16.9 or Chinese standard GB/T13401
Size Range
Sizes range from 1/2" to 48" (DN15-DN1200), with pressure ratings up to SCH10-XXS.
