Product Overview
An eccentric reducer is a butt weld pipe fitting used to connect two pipes of different diameters while aligning one side of the pipe. Unlike a concentric reducer, it has an offset centerline, making it ideal for horizontal pipelines to avoid air pockets or drainage issues. It ensures smooth transition and controlled flow in systems where level alignment is critical.

Frequently Asked Questions
Q1: What is the difference between concentric and eccentric reducers?
A1: An eccentric reducer has an offset centerline to maintain top or bottom pipe alignment, while a concentric reducer aligns both pipe centers.
Q2: When is an eccentric reducer used?
A2: Mainly in horizontal pipelines to prevent air pockets or to ensure proper drainage.
Q3: Do you supply both seamless and welded types?
A3: Yes, we offer both based on size, pressure, and application requirements.
Q4: What material grades are available?
A4: Available in stainless steel grades such as 304, 316L, 321, 310S, 2205, and 2507.
Q5: Are your reducers compliant with ASME B16.9?
A5: Yes, all reducers conform to ASME B16.9 and can meet DIN or EN standards as needed.
