ASTM A213 Alloy Steel Seamless Pipe Large Diameter Thick-Wall Boiler Tube for Heat Exchangers
ASTM A213 Alloy Steel Seamless Pipe (Tube) — Large Diameter, Thick-Wall for Boiler Service
Material
ASTM A213/A213M covers seamless ferritic and austenitic alloy-steel tubes intended for boilers, superheaters, and heat exchangers. Tubes are supplied as hot-finished or cold-finished, and can be specified with the heat-treatment condition required for high-temperature pressure parts. (Reference: ASTM A213/A213M)
Specifications
-
Manufacturing: Seamless; hot-finished or cold-finished (as specified). (Reference: ASTM A213/A213M)
-
Size capability (typical per standard scope): tubing commonly furnished from 1/8 in. ID to 5 in. OD with minimum wall 0.015–0.500 in.; other diameters may be supplied by agreement. (Reference: ASTM A213/A213M)
-
Testing options: Each tube is subject to hydrostatic test or nondestructive electric test; method is manufacturer’s option unless the PO specifies otherwise. (Reference: ASTM A213/A213M)
-
Marking: Includes hot-finished/cold-finished condition and wall designation (minimum wall or average wall). (Reference: ASTM A213/A213M)
-
Purchaser ordering checklist (recommended to avoid ambiguity): quantity, material name (seamless tubes), grade, condition, heat-treatment type, and any special requirements. (Reference: ASTM A213/A213M)
Key Features
-
High-temperature strength & creep resistance for boiler and superheater duties (Cr-Mo and higher-Cr families available).
-
Reliable pressure integrity from seamless manufacture and controlled heat treatment.
-
Fabrication-ready: suitable for expanding/beading, forging, welding, and bending when properly processed; Cr-bearing ferritic grades may require suitable post-heat treatment after hot work/welding. (Reference: ASTM A213/A213M)
Our Advantages
-
“Can you provide full traceability and a complete documentation package?”
Yes—deliveries are supported with CMTRs and a documentation set aligned with what major power/utility purchasers request (CMTRs, ISO certificate, inspection reports, wall thickness report, and NDT reports when applicable). (Reference: typical boiler-tubing purchaser QA requirements) -
“How do you control minimum wall thickness on thick-wall orders?”
We implement wall verification practices consistent with strict buyer QA expectations—sampling by lot/heat, multi-point end measurements, and reject/containment rules when readings fall below the minimum wall requirement. (Reference: typical boiler-tubing purchaser QA requirements) -
“Which NDT do I get—hydro or eddy-current—and can I mandate it?”
ASTM A213 allows hydrostatic or nondestructive electric testing on every tube; your PO can specify the required option. We can also support additional purchaser-requested examinations (e.g., eddy current sampling and reporting) commonly referenced in boiler-tubing QA programs. (Reference: ASTM A213/A213M)
