Hastelloy® C-22® Tubing

Hastelloy C-22 tubing is a good fit for hygienic applications that are typically high value with low tolerance for contamination, as in pharmaceutical and biopharmaceutical industries. CSI's active involvement with ASME-BPE subcommittees has resulted in the development of a stocking program for a complete line of sanitary-grade tubing in Hastelloy C-22.

CSI stocks Hastelloy C-22 tubing in sizes from 0.5 inch (12.7 mm) to 3 inches (76.2 mm). Whether you're looking for C-22 tubing, in-stock C-22 fittings, or custom-made equipment in C-22 and other materials, we have you covered.

In addition to Hastelloy C-22 tubing and fittings, CSI is ready to supply valves, pumps, and more in a variety of materials.

All C-22 tubing from CSI complies with EN10204, 3.1.
