ANSI B16.9 Stainless Steel Butt Weld Eccentric Reducer Class 150 Pipe Fittings
1. Product Description
Stainless Steel Reducer is a precision pipe fitting engineered to connect pipes of different diameters with smooth inner-wall transition. Manufactured by cold or hot forming, it is available in Concentric (center‑aligned) and Eccentric (flat‑side offset) designs, ensuring turbulence‑free flow, minimal pressure drop, and long‑term service reliability in demanding environments.
2. Product Applications
Oil & gas gathering and transmission lines
Chemical, petrochemical and refining plants
Municipal water supply and wastewater treatment
Power generation (thermal, nuclear, renewable)
Pharmaceutical, biotech and clean‑room facilities
Food, dairy and beverage processing
Offshore platforms, shipbuilding and marine piping
Pulp, paper and textile mills
HVAC and industrial refrigeration systems
3.Product Advantages
Premium austenitic and duplex stainless steels – excellent resistance to pitting, crevice corrosion and stress corrosion cracking.
High mechanical strength and fatigue resistance, suitable for cyclic pressure and temperature loads.
Precision machining ensures tight dimensional control and leak‑free butt‑weld or socket‑weld connections.
One‑piece forming (no longitudinal seam) reduces weak points; welded versions also available for large diameters.
Minimal maintenance – inherently rust‑proof, weather‑proof and chemical‑resistant.
Optimised internal profile yields pressure loss <5% over a wide service range (-20°C to 450°C with certain grades).
Full customisation – material grades, wall schedules, surface finishes and end preparations available on request.
