ASME SB622 Hastelloy C276 seamless pipe for petroleum and petrochemical use
ASME SB622 Hastelloy C276 Nickel alloy seamless pipe for petroleum and petrochemical use
ASME SB622 Hastelloy C276 seamless pipe is a highly corrosion-resistant nickel-molybdenum-chromium superalloy suitable for harsh environments such as the petroleum and petrochemical industries, particularly for conveying sour gases. Its key properties include excellent resistance to pitting, crevice corrosion, and high-temperature oxidation, as well as minimal carbide precipitation during welding. It is an ideal material for chemical processing, pollution control, and oil and gas production equipment.
What is the maximum operating temperature of Hastelloy C276?
Hastelloy C-276 is a nickel-molybdenum-chromium corrosion-resistant alloy. It resists pitting, crevice corrosion, and stress corrosion cracking. Hastelloy C-276 can be hardened simply by cold working. Hastelloy C-276 can operate at cryogenic temperatures up to a maximum temperature of 750℃F (400℃).

Sour Gas: A premium material for the recovery and treatment of sour natural gas containing corrosive hydrogen sulfide.
Chemical Processing: Used in equipment such as heat exchangers, reactors, evaporators, and pipelines.
Pollution Control: Suitable for flue gas desulfurization systems, scrubbers, and pipe linings.
Oil and Gas Production: Used in applications such as offshore oil drilling and components exposed to corrosive well fluids.
Standards: Conforms to ASME SB622, also known as UNS N10276.
Testing: Pipes undergo various tests to ensure quality, including chemical testing, mechanical strength testing (tensile, yield, elongation), and non-destructive testing such as hydrostatic pressure and radiography.
Availability: Available in a variety of sizes and lengths, often custom-made to customer specifications.
Gnee Steel specializes in the production of various nickel-based alloys. Gnee Steel's product packaging includes steel strapping: Pipes with an outer diameter of 3 inches or less are typically strapped together with polypropylene film to prevent rust during sea transportation, and then secured with steel strapping. Wooden boxes/crates: Pipes are typically packaged in wooden boxes or crates to protect them during transportation, especially those that are longer or have larger diameters. Seaworthy export packaging: Suppliers typically use standard seaworthy export packaging methods, which may include a variety of materials and techniques to protect the pipes during transportation. Tarpaulin packaging: This prevents rainwater, seawater, and other external factors from penetrating the export wooden crates during transportation. Gnee Steel specializes in the production and sale of alloy materials. Gnee Steel's products are widely used in aerospace, chemical, power, automotive, nuclear, and other industries, and we can provide customized alloy material solutions based on customer needs.
