Weight
Weight tables and schedules for specified outside diameters and specified wall thicknesses for steel pipe use ASME B36.10.

| Length ＞ 24 ft [7.3m] | agreement | |
| Straightness | The finished pipe shall be reasonably straight. | |
| Ends | Unless otherwise specified, the pipe shall be furnished with plain ends. All burrs at the ends of the pipe shall be removed. | |
| a If a definite length is not required, 1. order a single random length of pipe from 16 to 22 feet, with a maximum of 5% of the length between 12 and 16 feet; 2. order a double random length of pipe with a minimum average length of 35 feet and an absolute minimum length of 22 feet, with a maximum of 5% of the length between 16 and 22 feet. |

Defect and Handling
Defect
Surface imperfections that penetrate more than 12% of the nominal wall thickness or exceed the minimum wall thickness shall be considered defects,
and visual defects found to be more than 5% deeper than the nominal wall thickness are commonly referred to as scabs, seams, laps, tears, or slices.
Defect Handling
Defects may be eliminated by grinding, provided the remaining wall thickness is within specified limits and a smooth curved surface is maintained.
Sections of pipe containing defects may be cut within the limits of the length requirement.
ASTM A333 Marking
The manufacturer's name or brand, specification number (year of issue is not required), and grade should be clearly identified.
It should also include the temperature at which the impact test was performed after hot working, cold drawing, seamless or welded, the program number, and the letters "LT".
Markings shall begin at approximately 12 inches [300 mm].
For pipe less than NPS 2 and pipe less than 3 feet [1 m] in length, the required information may be marked on a label on the bundle or box in which the pipe is transported.
