ASME B16.9 Stainless Steel 304/316L Butt Weld Reducer Class 150 Pipe Fitting
1. Product Description
Stainless Steel Reducer (commonly known as reducing pipe fitting) is a vital component used to connect pipes of different diameters in piping systems. Manufactured from high-grade austenitic or duplex stainless steel, it is divided into Concentric Reducer (with aligned centerlines, suitable for vertical risers or pump discharges) and Eccentric Reducer (with parallel but offset centerlines, ideal for horizontal pipelines to prevent liquid pooling and air pockets).
Production methods include cold reduction, hot expansion, combined forming, and stamping. Seamless reducers are available from DN15 to DN500 (1/2″–20″), while welded (seam-welded) reducers range from DN15 to DN1200 (1/2″–48″), with custom sizes up to DN1800 (72″) on request. The products fully comply with GB/T, ASME, DIN, JIS, and other international standards.
2. Product Applications
Connecting pipes of different nominal diameters for smooth transition;
Installed at pump and compressor inlets/outlets to reduce fluid impact and cavitation;
Used upstream of flow meters, control valves, and heat exchangers to stabilize flow velocity;
Eccentric reducers are preferred for horizontal lines to facilitate drainage or venting and prevent water hammer;
Widely used in petrochemical, power generation, pharmaceutical, food & beverage, papermaking, marine, water treatment, and semiconductor industries.
3.Product Advantages
Superior Corrosion Resistance: Alloying elements such as Cr, Ni, and Mo provide excellent resistance to acids, seawater, and chlorides, far exceeding carbon steel lifespan;
High Strength & Temperature Resistance: Service range from -196℃ up to 800℃ (depending on grade), with capability to withstand high pressures;
Full Range of Sizes: Wall thickness schedules from SCH5S to SCH160S; custom dimensions available per drawings;
Excellent Weldability: Suitable for TIG, MIG, and SAW welding, with high joint strength and low crack risk;
Smooth Inner Surface: Low roughness prevents scaling and supports CIP cleaning, meeting hygienic standards;
Cost-Effective: Low total cost of ownership with long maintenance-free intervals.
