Stainless Steel  High Purity Sanitary Concentric Reducer
 
Stainless Steel High Purity Sanitary Concentric Reducer is a hygienic pipe fitting made of SS304/316LBPE Reducer with precision polished surface, Polished Reducer complying with ASME BPE, DIN 11864  Hygienic Reducer and other high-purity standards. It is widely used in hygienic process pipelinesin food, beverage, pharmaceutical and biotech industries, usually installed at sections where pipe diameter needs to change, such as pump outlets, equipment inlets or pipeline transitions, to smoothly adjust pipe size, reduce flow resistance and turbulence, and prevent medium residue.It is mainly divided into welded, clamp and threaded types to match different pipeline installation and clean production requirements.
 
Stainless Steel High Purity Sanitary Concentric Reducer differs from ordinary reducers with ultra-smooth polished surfaces,zero dead-leg design, and compliance withASME BPE & hygienic standards, ensuring no residue for food, pharma and biotech applications. Our products stand out with strict 316L material control,precision dimensional stability, higher pressure resistance, and stricter polish quality. We offer consistent performance, reliable certifications, and customized solutions, delivering superior durability and safety compared to standard suppliers.
