ASTM B366 UNS N06022 Nickel Alloy 180° SR Return Bends Hastelloy C22 Pipe Fittings B16.9
An ASTM B366 UNS N06022 180° SR Return Bend is a wrought (forged or seamless) nickel-alloy pipe fitting designed to reverse pipeline flow by 180°, routing it back parallel to its entry point. Manufactured from Hastelloy C22 — a Nickel-Chromium-Molybdenum-Tungsten alloy renowned for exceptional resistance to both oxidizing and reducing corrosive media — this fitting is produced under ASTM B366 (material specification) with dimensions generally per ASME B16.9. The "SR" (Short Radius) designation means its center-to-center return dimension equals 1.0 × Nominal Pipe Size (NPS), making it ideal for extremely tight spaces such as heat exchanger bundles.

Key Performance Advantages (Why C22 over C276?)
Superior Universal Resistance: Hastelloy C22 offers better overall corrosion resistance than C276 (UNS N10276) in oxidizing media (e.g., ferric chloride, chlorine) while retaining outstanding resistance to reducing acids.
Resistance to Pitting & Crevice Corrosion: Has a high Critical Pitting Temperature (CPT) and Crevice Corrosion Resistance, making it ideal for contaminated acids.
Stress Corrosion Cracking (SCC): Highly resistant to chloride-induced SCC.
Application
Chemical Processing: Handling hot contaminated acids (sulfuric, hydrochloric, phosphoric).
Flue Gas Desulfurization (FGD): Ducts and dampers in coal-fired power plants.
Pharmaceutical & Food: Where equipment must withstand harsh cleaning agents (bleach/chlorine).
Waste Treatment: Hazardous waste incinerators and scrubber systems.
