Hastelloy® C-22® Elbows

Hastelloy® C-22® 90° and 45° elbows (sometimes called bends) are available in sizes ½ – 3 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.

*20/32 µ-inch Max Ra is an approximate value and is not guaranteed. Surface finish roughness shall be physically examined for “P25” using a profilometer calibrated to standards traceable to NIST. Surface finish roughness shall NOT be subject to physical examination for “P7” or “7”.

**The interior surfaces shall be mechanically polished or as drawn to a 25 Ra µ-inch (0.8 µm) maximum finish for sizes ½” to 4” diameter (where available). The electropolishing process may increase the Ra values post electropolishing and have areas of preferential etching (e.g. frosting, shadowing, etc.). Final Ra values for electropolished tubing and fitting shall not be used as criteria of acceptance for this product.

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.
