Reducers for Pharmaceutical and Biotech

Central States Industrial (CSI) keeps an extensive stock of ASME-BPE compliant fittings for a short order turnaround.

Reducers are available that meet 2019 ASME-BPE standard. CSI also stocks the older, longer version under the 2012 standard. Call CSI for additional reducers for biopharmaceutical applications. For applications that require 3-A sanitary standards, CSI stocks Reducers for Food, Dairy, & Beverage. We also offer AL-6XN® Alloy Reducers and Hastelloy® C-22® Reducers for more corrosion resistance.

Models

These items are manufactured in compliance with the current revision of the ASME-BPE Standards.
