Finished pipe shall be commercially straight.
This is a summary of ASTM specifications. Data sheets for overmetals, plastics, ceramics, and composites. When specific straightness requirements are desired, the order should so state and be agreed upon between the purchaser and a39 manufacturer. The grades of steel are pipe mill grades having mechanical properties which differ from standard plate grades.
The minimum wall thickness at any point shall be not more than Defects in the welds, such as sweats or leaks, shall be repaired or the piece rejected at the option of the manufacturer. Test pressure shall be held for not less than 5 sec.

Click here to view all the property values for this datasheet as they were originally entered into MatWeb. Link to Active This link will always route to the current Active version of the standard. 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.

Repairs of this nature shall be made by completely removing the defect, cleaning the cavity, and then 1a39.
Tensile strength z139 Ksi Mpa. One reduced-section production weld test specimen shall be taken from a length of pipe from each lot of ft.
ASTM A139 and ASME SA139 Carbon Steel Tubes
Historical Version s – view previous versions of standard. The values in each system are not exact equivalents; therefore, each system is to be used independently of the other.
The pressure shall be determined by the following equation: Within the text, the SI units are shown astmm brackets. When agreed upon by the aastm and the manufacturer and so stated on the order, pipe may be tested: Questions or comments about MatWeb? Pipe of NPS 4 Note 1 and larger with nominal average wall thickness of 1. We advise that you only use the original value or one of its raw conversions in your calculations to minimize rounding error.
When 1a39 upon by the purchaser and the manufacturer and so stated on the order, pipe may be tested:. MatWeb is intended for personal, asmt use. The pipe shall be substantially round.

Thickness The minimum wall thickness at any point shall be not more than Heat analysis of each heat of steel was made to determine the percentage of the elements as per chemical requirements. The suitability of pipe for various purposes is somewhat dependent on its dimensions, properties, and conditions of service.
