This specification covers five grades of electric-fusion arc -welded straight-seam or helical steel pipe including pipe of NPS 4 and over.
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 adtm 1 ” inclusive.
For example, for high-temperature service see applicable codes and Specification A The minimum wall thickness at any point shall be not more than The suitability of wstm for various purposes is somewhat dependent on its dimensions, properties, and conditions of service.
Pipe of NPS 4 Note 1 and larger with nominal average wall thickness of 1. Tensile strength ,min Ksi Mpa. Defects in the welds, such as sweats or leaks, shall be repaired or the piece rejected at the option of the manufacturer. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
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. Link to Active This link aa139 always route to the current Active version of the standard.
This abstract is a brief summary of the referenced standard. All repaired pipe shall be subject to hydrostatic testing.
When specific straightness requirements are desired, the order should so state and be agreed upon between the purchaser and the manufacturer.

The outside circumference of the pipe shall not vary more than 1. Data sheets for overmetals, plastics, ceramics, and composites. Repairs of this nature shall be made by completely removing the defect, cleaning the cavity, and then welding.
Users requiring more precise data for scientific or engineering calculations can click on the property value to see the original value as well as raw conversions to equivalent units. One longitudinal tension test specimen shall be made from the steel of each heat, or fraction thereof, used in the manufacture of the pipe. All burrs at the ends of pipe shall be removed. The values in each system are not exact equivalents; therefore, each system is to be used independently of the other.
