Hastelloy® C-22® Adapters

Hastelloy C-22 pipe adapters allow you to more smoothly connect pipe to tube, tube to hose, ferrule to tube, and more. Choose from butt weld or Tri-Clamp® connections. CSI's large variety of adapters provide more flexibility to build your corrosion-resistant process line how you want it.

For applications that require 3-A sanitary standards or ASME-BPE standards, CSI stocks 304 and 316L Stainless Steel Adapters. We also offer AL-6XN® Adapters as another corrosion-resistant option.

Length 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.

***Sanitary Finish: Offering finish better than traditional commercial grade tube finish. Suitable for applications in sanitary/high purity hygienic industries.

Pipe Adapters

CSI's pipe-to-tube adapters smoothly transition from schedule pipe sizes to OD tube sizes. The adapters come with either a butt weld or Tri-Clamp tube connection.

Features
  • Tapered for smooth flow
  • Squared ends (for single-pass fusion welding) in Schedule 5 and Schedule 10
  • Standard pipe bevel on Schedule 40
  • Reducing sizes are also available

More Adapters

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. At CSI, we stock polished fittings, and unpolished fittings are available upon request.

For 304 and 316L adapters that meet 3-A sanitary or BPE standards, visit the Adapters for Food, Dairy, & Beverage and BPE Adapters pages. CSI also offers AL-6XN® Alloy Adapters.
