Hastelloy Flanges

Hastelloy Pipe Flanges have exceptional resistance to non-oxidizing acids including sulfuric and hydrochloric acid. Hastelloy Flange is a true performance breakthrough for chemical process equipment applications because it combines excellent resistance to oxidising media with exceptional resistance to non-oxidizing conditions. The most advanced pharmaceutical reaction vessels and the most corrosive FGD systems have both been protected Hastelloy Flange, which is exceptionally resistant to pitting and crevice corrosion.

The phosphoric acid heat exchanger tubing and other process components in the fertiliser sector have seen great success with Hastelloy Plate Flanges. Hastelloy Flanges are the best options for strong oxidising solutions and mixed acid pickling services because to their high chromium content.
