Polished Stainless Steel Reducer

Polished Stainless Steel Reducer

Product Overview

Our Polished Stainless Steel Reducer is a premium pipe fitting engineered to join two pipes of different diameters while ensuring a smooth, contaminant-free transition. Available in both concentric and eccentric designs, this fitting features a high-quality surface finish achieved through mechanical polishing or electropolishing. This specialized finish creates a mirror-like surface that is critical for preventing bacterial adhesion, minimizing pressure drop, and facilitating easy cleaning (CIP/SIP). It is the standard choice for sanitary piping systems where purity and hygiene are non-negotiable.

Key Features and Benefits

• Superior Surface Finish: Available in Ra ≤ 0.8µm (320 grit), Ra ≤ 0.5µm (400 grit), or Electropolished (EP) finishes to ensure a non-stick, easy-to-clean surface.

• Hygienic Design: The polished interior eliminates micro-crevices where bacteria or contaminants could hide, meeting strict sanitary standards for food and pharmaceutical processing.

• Flow Efficiency: The smooth internal surface reduces friction and turbulence, ensuring consistent flow rates and preventing product buildup.

• Corrosion Resistance: Manufactured from high-grade Austenitic Stainless Steel (304/304L, 316/316L), offering excellent resistance to rust and chemical attack.

• Precision Engineering: Available in Concentric (aligned centers) and Eccentric (flat side) configurations to suit specific pipeline requirements, machined to tight tolerances.

Applications

The polished finish makes these reducers indispensable in industries where cleanliness and product purity are paramount:

• Pharmaceutical & Biotechnology: For purified water (WFI), clean steam, and sterile process lines.

• Food & Beverage: Dairy, brewing, and juice processing where preventing bacterial growth is critical.

• Cosmetics: Manufacturing high-end creams and lotions requiring contamination-free transfer.

• Semiconductor: High-purity chemical and gas distribution systems where particle generation must be minimized.

Quality Assurance

We maintain strict quality control over the polishing process to ensure uniformity and surface integrity. Each batch undergoes surface roughness testing (using a profilometer), dimensional inspection, and material verification. We provide full traceability and documentation, including EN 10204 3.1 Mill Test Certificates and surface finish reports, to guarantee compliance with ASME BPE and other sanitary standards.
