Ordering Information
It shall be the responsibility of the purchaser to specify all requirements that are necessary for products under this specification. Such requirements to be considered include, but are not limited to, the following:
Quantity (feet, metres, or number of lengths),
Name of material (seamless tubes),
Grade (Tables 1 and 2),
Condition (hot finished or cold finished),
Controlled structural characteristics (see 6.3),
Size (outside diameter and minimum wall thickness, unless average wall thickness is specified),
Length (specific or random),
Hydrostatic Test or Nondestructive Electric Test (see 10.1),
Specification designation and year of issue,
Increased sulfur (for machinability, see Note B, Table1, and 16.3), and Special requirements and any supplementary requirements selected.
Stress-Relieved Annealed Tubes
For use in certain corrosives, particularly chlorides where stress corrosion may occur, tubes in Grades TP304L, TP316L, TP321, TP347, and TP348 may be specified in the stress-relieved annealed condition.
When stress-relieved tubes are specified, tubes shall be given a heat treatment at 1500 to 1650 °F [815 to 900 °C] after roll straightening. Cooling from this temperature range may be either in air or by slow cooling. No mechanical straightening is permitted after the stress-relief treatment.
Straightness of the tubes shall be a matter of negotiation between the purchaser and supplier
