This is ASTM A 53 pipe specification part 2, part 1 please see this. ASTM A 53 pipe specification is Standard Specification for Pipe, Steel, Black and Hot-Dipped, Zinc-Coated, Welded, and Seamless. ASTM A 53 pipe specification part 1 including the first 13 items.
Why we provide the specification? All pipe should make according to specification like if you need API 5L PSL 1 or PSL 2 pipe. We should manufacture acc. to API 5L specification. And purchase required steel grade plate. The items list below is the following items list in the ASTM a 53 specification.
14. Workmanship, Finish, and Appearance in ASTM A 53 Specification
14.1 The pipe manufacturer shall explore a sufficient number of visual surface imperfections. And to provide reasonable assurance that they have been properly evaluated with respect to depth in ASTM a 53 specification.
14.2 Surface imperfections that penetrate more than 121⁄2 % of the nominal wall thickness. Or encroach on the minimum wall thickness shall be considered defects. Pipe with defects shall be given one of the following dispositions:
14.2.1 The defect shall be removed by grinding, provided that the remaining wall thickness is within specified limits,
14.2.2 Type S pipe and the parent metal of Type E pipe, except within 1⁄2 in. [13 mm] of the fusion line of the electric resistance seam; Are permitted to be repaired in accordance with the welding provisions of 14.5. Repair welding of Type F pipe and the weld seam of Type E is prohibited.
14.2.3 The section of pipe containing the defect may be cut off within the limits of requirement on length, or
14.3 At the purchaser’s discretion, pipe shall be subjected to rejection if surface defects repaired in accordance with 14.2 are not scattered. But appear over a large area in excess of what is considered a workmanlike finish.
Disposition of such pipe shall be a matter of agreement between the manufacturer and the purchaser.
14.4 When imperfections or defects are removed by grinding, a smooth curved surface shall be maintained. And the wall thickness shall not be decreased below that permitted by this specification.
It shall be permissible to reduce the outside diameter at the point of grinding by the amount so removed.
14.4.1 Wall thickness measurements shall be made with a mechanical caliper. Or with a properly calibrated nondestructive testing device of appropriate accuracy.
In the case of a dispute, the measurement determined by the use of the mechanical caliper shall govern.
