Elbows for Pharmaceutical and Biotech

Central States Industrial (CSI) keeps an extensive stock of fittings, ready to ship immediately, for high-purity applications. Alfa Laval ensures that all angles are exact and that all tube, bend, and tee connections are uniform, so you do not have to compensate for any welding irregularities.

All pharmaceutical and biotech fittings comply with the current version of ASME-BPE standards. Available in four finishes, PC and PL finishes have a contact surface finish of 20 microinch Ra, while PD and PM finishes are electropolished with a contact surface finish of 15 microinch Ra. All BPE items are individually capped and bagged in clear 6 mil. Poly bags. All products are labeled with a bar code, product information, and manufacturing date.

For applications that require 3-A sanitary standards, CSI stocks Elbows for Food, Dairy, & Beverage. We also offer AL-6XN® Alloy Elbows and Hastelloy® C-22® Elbows for more corrosion resistance.

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