ANSI B16.9 Stainless Steel Butt Weld Eccentric Reducer Class 150 Pipe Fittings
1. Product Description
The Stainless Steel Reducer is a high-integrity pipe fitting engineered for reliable diameter reduction or expansion within fluid handling systems. Fabricated from premium corrosion-resistant alloys, it delivers smooth transitional geometry that minimises flow disturbance. Offered in Concentric (axially symmetric) and Eccentric (flat-aligned offset) configurations, it accommodates diverse installation orientations and service conditions.
2. Product Applications
Long-distance oil & gas trunk lines
Refinery and cracking units
Industrial water distribution and desalination plants
Thermal, combined-cycle and nuclear power stations
Sterile processing in biotechnology
CIP/SIP systems in dairy, brewery and juice production
Floating production storage and offloading (FPSO) vessels
Metallurgical and mining slurry handling
District heating and cooling networks
3.Product Advantages
Wide selection of austenitic, ferritic and duplex stainless steels to match specific corrosivity levels.
Superior dimensional consistency – roll‑formed or forged construction with fully penetrated weld preparation.
Enhanced structural integrity – seamless designs eliminate seam-related failure modes; welded options offer cost-effectiveness for large diameters.
Excellent surface finish options reduce fouling and facilitate clean-in-place operations.
Engineered transition profile yields pressure recovery and energy savings over extended duty cycles.
Full traceability with heat number stamping and mill test certificates (EN 10204 3.1/3.2).
Flexible manufacturing – non-standard diameters, custom wall thicknesses and special bevel angles accepted.
