ASTM A and ASME SA Carbon Steel Tubes
All burrs at the ends of pipe shall be removed. Test pressure shall be held for not less than 5 sec. The steel shall be made by one or more of the following processes: Repairs of this nature shall be made by completely removing the defect, cleaning astn cavity, and then welding.
We appreciate your input. A1399 in the welds, such as sweats or leaks, shall be repaired or the piece rejected at the option of the manufacturer.
The suitability of pipe for various awtm is somewhat dependent on its dimensions, properties, and conditions of service. The pipe is intended for conveying liquid, gas, or vapor. One longitudinal tension test specimen shall be made from the steel of each heat, or fraction thereof, used in the manufacture of the pipe. 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.
