ASTM A210 Heat Exchanger Tubes
Nov 04, 2025
ASTM A210: Standard Specification for Seamless Medium-Carbon Steel Boiler and Superheater Tubes
Scope of Application:
Applications: Suitable for boiler tubes, boiler flue tubes, including safety ends, vaults, support tubes, and superheater tubes.
Size Range: Typically covers pipes with outer diameters from 1/2 inch to 5 inches (12.7 mm to 127 mm) and minimum wall thicknesses from 0.035 inch to 0.500 inch (0.9 mm to 12.7 mm). Other sizes may be provided if all other standard requirements are met. Mechanical performance requirements do not apply to tubes with an inner diameter less than 1/8 inch (3.2 mm) or a thickness less than 0.015 inch (0.4 mm).
Manufacturing Process:
Forming: Pipes must be manufactured using seamless processes to ensure structural integrity and uniformity for high-temperature, high-pressure environments.
Heat Treatment: Appropriate heat treatment may be applied based on grade and end-use requirements.
Inspection & Testing:
Tensile Test: One sample per batch of ≤50 pipes; two samples per batch of >50 pipes.
Flattening Test: One sample per batch (not used for flaring), tested at each end. For Grade C pipes ≤2.375 inches (60.3 mm), tears or cracks at 12/6 o'clock positions are not grounds for rejection.
Flaring Test: One sample per batch (not used for flattening), tested at each end.
Hardness Test: Two pipes per batch for Brinell or Rockwell hardness testing.
Hydrostatic Test or NDT: Every pipe must undergo hydrostatic testing; NDT may replace it if specified by the buyer.
6. Product Marking:
Pipes must be marked with the standard number, grade, dimensions, production details, and heat number for traceability and quality control.
