316L Tees and Crosses for Pharmaceutical and Biotech

CSI has an extensive stock of fittings that comply with ASME-BPE standards. CSI's inventory includes several instrument tee and cross styles to fit any application.

CSI's pharmaceutical and biotech fittings comply with the current version of ASME-BPE standards and are 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. Alfa Laval ensures that all angles are exact and all tube, bend, and tee connections are uniform, so there is never a need to compensate for any welding irregularities.

All BPE items are individually capped and bagged in clear 6 mil. poly bags. Each item is labeled with a bar code, product information, and manufacturing date.

For applications that require 3-A Sanitary Standards, CSI stocks 304 and 316L tees and crosses for food, dairy, and beverage. CSI also offers AL-6XN® alloy tees and crosses and Hastelloy® C-22® tees for more corrosion resistance.

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