This is a summary of ASTM specifications. The pipe shall be substantially round. The grades of steel are pipe mill grades having mechanical properties which differ from standard plate grades. Pipe having other dimensions may be furnished provided such pipe complies with all other requirements of this specification and the grades of steel of the manufactured pipes. For additional details and information, please refer to these specifications.

Within the text, the SI units are shown in brackets. 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. Circumference The pipe shall be substantially round.

Heat analysis of each heat of steel was made to determine the percentage of the elements as per chemical requirements. We appreciate your input. This specification covers five grades of electric-fusion arc -welded straight-seam or helical steel pipe including pipe of NPS 4 and over.

The pressure shall be determined by the following equation: Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. The values in each system are not exact equivalents; therefore, each system is to be used independently of the other.

For example, for high-temperature service see applicable codes and Specification A Data sheets for overmetals, plastics, ceramics, and composites. The suitability of pipe for various purposes is somewhat dependent on its dimensions, properties, and conditions of service.
