ASTM B474/B474M-19(2023) — Electric Fusion-Welded Nickel-Alloy Pipe
Procurement reference for electric fusion-welded nickel and nickel-alloy pipe under ASTM B474/B474M.
Edition control: ASTM B474/B474M-19(2023) is the active edition identified in the official ASTM catalogue checked on 1 September 2026. Confirm the authorised publication and purchase-order requirements before use.
Scope in Procurement
ASTM B474/B474M covers electric fusion-welded nickel and nickel-alloy pipe for high-temperature or corrosive service. The exact alloy, class and welded-joint examination route must be selected in the inquiry and purchase order.
RFQ and Product Controls
- Exact alloy and ASTM B474/B474M-19(2023) edition
- High-temperature or corrosive-service duty and governing piping or equipment code
- Selected pipe class, nominal size, wall basis, length, ends and tolerances
- Fusion-welding process, filler metal, full-penetration joint and repair controls
- Heat treatment and chemical requirements for plate and weld metal
- Transverse tension, guided-bend, pressure and selected radiographic examination
- ASTM B775/B775M requirements, inspection document, traceability, marking and destination
The material identity must remain traceable from the producing heat and lot through manufacture, welding or seamless processing, heat treatment, testing, inspection documentation, marking and final release.
Scope Boundary
ASTM B474/B474M is an electric fusion-welded pipe route, not a seamless or automatic no-filler welded specification. Its classes are not interchangeable, and alloy selection, welding qualification, design code and corrosion assessment remain separate project controls.
