ASTM A53 carbon steel pipe suitable for structural, mechanical and pressure-line applications. Available in both seamless and welded construction, with black (plain) or hot-dip galvanized surface options and multiple protective coatings for corrosion resistance.
Key features
- Standards: Manufactured to ASTM A53 / ASME SA-53 (also available to related ASTM/ASME/API requirements on request)
- Construction: Seamless and welded (ERW/SAW) options
- Nominal sizes: 1/2" NB up to 36" NB
- Wall thickness: Typically 3–12 mm (custom thicknesses available within product limits)
- Schedules: SCH 40, SCH 80, SCH 160, SCH XS, SCH XXS and other schedules on request
- Surface finishes: Bare (as-rolled), oiled, mill varnish, hot-dip galvanized, FBE, dual FBE, 3LPE
- End finishes: Beveled, square cut, threaded (other end preparations available on request)
Typical applications
- Pressure and mechanical service such as steam, water, gas and air lines
- Structural and fabrication uses including bending, flanging and welding
- General-purpose piping and continuous-welded pipeline where ASTM A53 properties meet project requirements
Quality, inspection and documentation
- Supply with Mill Test Certificates and chemical / mechanical reports
- EN 10204 test documentation available as specified
- PMI (positive material identification) reports, visual inspection, non-destructive testing and third-party inspection available on request
Coating and galvanizing note
ASTM A53 specifies minimum coating/galvanizing mass requirements typical for general pipe use. It does not include the broader appearance and adhesion requirements found in ASTM A123 (hot-dip galvanizing specification); if ASTM A123 compliance is required, confirm this at inquiry stage so galvanizing can be applied and inspected to that standard.
Ordering
Provide size (NB), wall thickness or schedule, construction type (seamless or welded), length or cut lengths, required surface/end finish and any inspection/certification needs when requesting a quote.
