ASME SA-214-SA-214M-2021 pdf free download.SPECIFICATION FOR ELECTRIC-RESISTANCE- WELDED CA RBON STEEL HEAT-EXCHANGER AND CONDENSER TUBES.
1.1 This specification covers minimum-wall-thickness, electric-resistance- welded, carbon steel tubes to be used for heat exchangers, condensers, and similar heat-transfer apparatus.
1.2 The tubing sizes usually furmished to this specifica- tion are to 3 in. [76.2 mm] in outside diameter, inclusive. Tubing having other dimensions may be furnished, pro- vided such tubes comply with all other requirements of this specification.
1.3 Mechanical property requirements do not apply to tubing smaller than /g in. [3.2 mm] in inside diameter or 0.015 in. [0.4 mm] in thickness.
1.4 The purchaser shall specify in the order the outside diameter and minimum wall thickness. The inside diameter shall not be specified.
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.

3. General Requirements
3.1 Material furnished under this specification shall conform to the applicable requirements of the current edi- tion of Specification A 450/A 450M, unless otherwise pro- vided herein.
4. Ordering Information
4.1 Orders for material under this specification should include the following, as required, to describe the desired material adequately:
4.1.1 Quantity (feet, metres, or number of lengths),
4.1.2 Name of material (electric- resistance-welded tubes),
4.1.3 Size (outside diameter and minimum wall thickness),
4.1.4 Length (specific or random),
4.1.5 Optional requirements (Section 8 and 10.5),
4.1.6 Test report required (see Certification Section of Speification A 450/A 450M),
4.1.7 Specification designation, and 4.1.8 Special requirements. 5. Manufacture 5.1 Tubes shall be made by elctric resistance welding.
6. Heat Treatment
6.1 After welding, all tubes shall be heat treated at a temperature of 1650°F [900C] or higher and followed by cooling in air or in the cooling chamber of a controlled atmosphere furmace. Cold drawn tubes shall be heat treated after the final cold draw pass at a temperature of 1200°F [650C] or higher.ASME SA-214 pdf download.
