The pressure shall be determined by the following equation: The pipe shall be substantially round. This specification covers five grades of electric-fusion arc -welded straight-seam or spiral-seam steel pipe in 4″ to 92″ inclusive with wall thickness up to aztm ” inclusive. Straightness Finished pipe shall be commercially straight. Heat analysis of each heat of steel astn made to determine the percentage of the elements as per chemical requirements.

ASTM A139 and ASME SA139 Carbon Steel Tubes

One reduced-section production weld test specimen shall be taken from a length of pipe from each lot of ft. The contents, results, asm technical data from this site may not be reproduced either electronically, photographically or substantively without permission from MatWeb, LLC.

All burrs at the ends of pipe shall be removed. The required chemical composition, tensile requirements of the steel, and the tensile requirements of the production welds are presented.

The values in each system are not exact equivalents; therefore, each system is to be used independently of the other. The suitability of pipe for various purposes is somewhat dependent on its dimensions, properties, and conditions of service. The steel shall conform to the following chemical requirements: Questions or comments about MatWeb? Repairs of this nature shall be made by completely removing the defect, cleaning the cavity, and then welding.


Finished pipe shall be commercially straight. For example, for high-temperature service see applicable codes and Specification A Thickness The minimum wall thickness at any point shall be not more than Login to see your most recently viewed materials here.

ASTM A Steel, grade B

Aatm in the welds, such as sweats or leaks, shall be repaired or the piece rejected at the option of the manufacturer. This specification covers five grades of electric-fusion arc -welded straight-seam or helical steel pipe including pipe of NPS 4 and over.

This is a summary of ASTM specifications. Test pressure shall be held for not less than 5 sec.

ASTM does not give any warranty express or implied or make any representation that the contents of w139 abstract are accurate, complete or up to date. When specific straightness requirements are desired, the order should so state and be agreed upon between the purchaser and the manufacturer. Within the text, the SI units are shown in brackets. The grades of steel are pipe mill a19 having mechanical properties which differ from standard plate grades.

When agreed upon by the purchaser and the manufacturer and so stated on the order, pipe may be tested: Tests to be performed shall include one longitudinal tension test for the steel, one reduced-section production weld test for the pipe, and hydrostatic test for each length of the pipe.


One longitudinal tension test specimen shall be made from the steel of each heat, or fraction thereof, used in the manufacture of the pipe. The steel shall be made by one or more of the following processes: It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application.
