Frequently Asked Question

How is Hastelloy C-22 pipe typically used in industrial settings?

Hastelloy C-22 pipe is commonly used in chemical processing, steel making and petrochemical industries. It has a good corrosion resistance and strong strength, which can be used to transport corrosive chemicals, process hot acid solutions, and handle high-temperature equipment that is exposed to harsh conditions.

What are the main benefits of choosing Hastelloy C-22 pipe over other materials?

The main advantages are high resistance to oxidizing, reducing chemicals, particularly chlorides and oxidizing acids. It also has excellent strength, high-temperature resistance up to 1250F (677C), and versatile fabrication capabilities, with customized dimensions and finishes.

When should I consider using custom wall thickness or end types?

When certain pressure ratings, flow rates or types of connections are necessary in your process, a custom wall thickness or a specific end type (plain, bevel, threaded) becomes the only choice. This will ensure maximum performance and compatibility with existing piping systems or special installation locations.
