Introduction

Hastelloy C276 Pipe (also Alloy C276 Pipe, UNS N10276 Pipe, ASTM B622 C276 Pipe, ASTM B619 C276 Welded Pipe, Nickel Alloy C276 Pipe, Corrosion Resistant Alloy Pipe) is a nickel‑molybdenum‑chromium alloy with outstanding resistance to a wide range of aggressive chemicals, including hydrochloric acid, sulfuric acid, wet chlorine, and chlorides. It conforms to ASTM B622 (seamless), ASTM B619 (welded), and ASTM B626 (tube), as well as ASME SB622 / SB619. The alloy is designated UNS N10276 and W.Nr. 2.4819, meeting Hastelloy C276 Specification worldwide.

This nickel alloy C276 pipe delivers exceptional corrosion resistance alloy, hydrochloric acid resistant pipe, sulfuric acid resistant alloy, chloride corrosion resistant pipe, pitting resistant nickel alloy, crevice corrosion resistant alloy, seawater resistant alloy pipe, oxidizing and reducing media resistance, high temperature corrosion resistance, and aggressive chemical service alloy.

Note: Hastelloy C276 is one of the most versatile corrosion‑resistant alloys, suitable for both oxidizing and reducing environments, with excellent resistance to pitting, crevice corrosion, and stress corrosion cracking.

Our Hastelloy C276 pipes and tubes are available in seamless (ASTM B622) and welded (ASTM B619) forms, with cold drawn, hot finished, pickled, and polished surface finishes. We offer custom sizes, cut to length, and large diameter options, with Schedule 40, Schedule 80, and custom schedules.

Key standards: ASTM B622 (seamless), ASTM B619 (welded), ASTM B626 (tube), ASME SB622/SB619, UNS N10276, W.Nr. 2.4819.

Applications

1. Chemical Processing & Acid Plants

• Hastelloy C276 pipe for chemical processing – reactor feed lines, distillation column piping, heat exchanger tubing, and transfer lines in organic and inorganic chemical plants. Exceptional corrosion resistance alloy handles mixed acids, chlorine, and chlorides.

• Hastelloy C276 pipe for hydrochloric acid service – piping systems for hydrochloric acid production, storage, and transfer. Hydrochloric acid resistant pipe withstands all concentrations up to boiling point.

• Hastelloy C276 pipe for sulfuric acid plants – heater tubes, absorber columns, and acid circulation lines. Sulfuric acid resistant alloy performs well in dilute and intermediate concentrations up to 150°C.

2. Flue Gas Desulfurization (FGD) & Scrubber Systems

• Hastelloy C276 pipe for flue gas desulfurization – FGD absorber spray headers, recirculation piping, and slurry lines in coal‑fired power plants. Chloride corrosion resistant pipe withstands high‑chloride, low‑pH environments.

• Hastelloy C276 pipe for scrubber systems – marine SO₂ scrubbers, industrial air pollution control scrubbers, and vent gas cleaning systems. Pitting resistant nickel alloy prevents costly downtime.

3. Offshore Oil & Gas, Seawater & Marine Applications

• Hastelloy C276 pipe for offshore oil and gas – topside chemical injection lines, subsea control tubing, and produced water piping. Seawater resistant alloy pipe resists both H₂S/CO₂ corrosion and chloride pitting.

• Hastelloy C276 pipe for seawater applications – seawater cooling lines, ballast systems, and firewater mains. Crevice corrosion resistant alloy is immune to microbiologically influenced corrosion (MIC).

4. Waste Treatment & Petrochemical Industry

• Hastelloy C276 pipe for waste treatment plants – hazardous waste incinerator scrubbers, landfill leachate piping, and chemical waste neutralization lines. Aggressive chemical service alloy handles variable pH and oxidizing conditions.

• Hastelloy C276 pipe for petrochemical industry – acetic acid, vinyl chloride monomer (VCM), and polyester plant piping. High temperature corrosion resistance up to 400°C.

5. Heat Exchangers & High Temperature Service

• Hastelloy C276 pipe for heat exchangers – shell‑and‑tube heat exchangers for corrosive fluids, condenser tubes, and evaporator coils. Excellent resistance to both oxidizing and reducing media.
