Hastelloy® C-22® Elbows
Hastelloy® C-22® 90°, 88°, 92°, and 45° elbows (sometimes called bends) are available in sizes ¼ – 4 inches. Both butt weld and Tri-Clamp® options are available.
For applications that require 3-A sanitary standards or ASME-BPE standards, CSI stocks Elbows for Food, Dairy, & Beverage and BPE Elbows in 304 and 316L. We also offer AL-6XN® Elbows as another corrosion-resistant option.
Dimensions are consistent with industry standards.
CSI stocks a complete line of corrosion-resistant, sanitary fittings in Hastelloy C-22 in sizes ½ – 3 inch. We offer standard items as well as made-to-order fittings. C-22 fittings can be used interchangeably with Hastelloy C-276.

More Elbows
Typically, CSI stocks butt weld fittings. If you're looking for a different connection, we can also provide Tri-Clamp, I-line, SMS, or DIN options. Most of our fittings are offered in standard BPE dimensions. We stock polished fittings at CSI, and unpolished fittings are available upon request.
For elbows in 304 or 316L that meet 3-A sanitary or BPE standards, visit the Elbows for Food, Dairy, & Beverage and BPE Elbows pages. CSI also offers AL-6XN® Alloy Elbows.
