Product Description

Boiler Alloy Steel Pipe

ASTM A210 tubes

ASTM A210 tubes are medium carbon steel Seamless Tubing used in boilers, boiler flues, super heaters.

ASTM A210 / ASME SA210 is available in A210 Grade A1, and A210 Grade C.

What is ASTM A210?

ASTM A210 is the standard covers seamless medium-carbon steel boiler and superheater tubes. Seamless medium Carbon Steel Pipe for boiler tube and boiler flue pipe, including a minimum wall thickness of the security side, the dome and the support tube and superheater tubes.

Seamless medium carbon Steel Pipe for boiler tube and boiler flue pipe, including a minimum wall thickness of the security side, the dome and the support tube and superheater tubes.

Delivery Condition: Annealed, Normalized, Normalized and Tempered

Surface treatment: Oil-dip, Varnish, Passivation, Phosphating, Shot Blasting

Application: For high, middle, low pressure boiler and pressure purpose

Scope

1.1 This specification2 covers minimum-wall-thickness, seamless medium-carbon steel, boiler tubes and boiler flues, including safe ends (see Note 1), arch and stay tubes, and superheater tubes.

NOTE 1: This type is not suitable for safe ending by forge welding.

1.2 The tubing sizes and thicknesses usually furnished to this specification are 1/2 in. to 5 in. [12.7 to 127 mm] in outside diameter and 0.035 to 0.500 in. [0.9 to 12.7 mm], inclusive, in minimum wall thickness. Tubing having other dimensions may be furnished, provided such tubes comply with all other requirements of this specification.

1.3 Mechanical property requirements do not apply to tubing smaller than 1/8 in. [3.2 mm] in inside diameter or 0.015 in. [0.4 mm] in thickness.

1.4 This specification covers grades A-1 and C of Seamless Medium-Carbon Boiler and Superheater Tubes with different chemical and tensile requirements. (Table 1, Table 3, and Section 11.)

1.5 The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values from the two systems may result in nonconformance with the specification. The inch-pound units shall apply unless the “M” designation of this specification is specified in the order.

1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Mechanical Tests Required

(1)Tension Test—One tension test shall be made on a specimen for lots of not more than 50 tubes. Tension tests shall be made on specimens from two tubes for lots of more than 50 tubes.
(2)Flattening Test—One flattening test shall be made on specimens from each end of one finished tube from each lot.
(3)Flaring Test—One flaring test shall be made on speci- mens from each end of the one finished tube from each lot.
(4)Hardness Test—Brinell or Rockwell hardness tests shall be made on specimens from two tubes from each lot.
(5)Hydrostatic or Nondestructive Electric Test—Each tube shall be subjected to the hydrostatic.

ASTM A210 / A210M Flattening Test

One flattening test shall be made on specimens from each end of one finished tube from each lot, but not the one used for the flaring test. Tears or breaks occurring at the 12 or 6 o’clock positions on Grade C tubing with sizes of 2.375 in. [60.3 mm] in outside diameter and smaller shall not be considered a basis for rejection.
