ASTM A622 Alloy

Seamless pipe and tube manufactured to the ASTM A622 specification for nickel and nickel–cobalt alloys, supplied for industrial and process applications that demand corrosion resistance and high strength at elevated temperatures. Material grades are determined by chemical composition and mechanical properties (tensile strength, yield strength, elongation) to meet application-specific requirements.

Key features

• Conforms to ASTM A622 requirements for nickel and nickel–cobalt seamless pipe and tube
• Available in multiple grades classified by chemical and mechanical properties
• Typical production and inspection: tension testing, hydrostatic testing, and nondestructive electric testing on each pipe or tube
• Chemical composition verified for each heat; mass/weight of each length calculated and documented
• Supplied lengths, diameters, wall thicknesses and surface finishes tailored to project needs

Delivery options and forms

• Standard supply: seamless pipe and tube in straight lengths
• Many suppliers also provide related product forms (plates, hot‑rolled coils and strip) for fabricating components that require severe drawing or forming; clarify delivery condition and surface finish when ordering

Documentation and quality control

• Material Test Reports (MTRs) showing chemical and mechanical test results can be provided on request
• Non‑destructive testing (electrical or other NDT), hydrostatic testing and dimensional inspections performed per order requirements

Typical applications

• Chemical and petrochemical process equipment
• Heat exchangers and condensers
• Pressure vessels and piping systems in high‑temperature or corrosive environments
• Marine, power generation and oil & gas installations

Ordering and customization

• Specify required ASTM grade, dimensions (OD, wall thickness, length), end preparation and surface finish
• Request copies of inspection certificates, test reports and other documentation when placing an inquiry

For pricing, availability and to request technical datasheets or certificates, please provide project specifications (grade, sizes, quantities and intended application) so the supplier can prepare an accurate quotation.
