This specification covers standard requirements for seamless, black, plain-end steel pipes for use in the conveyance of fluids under pressure. A quantity of pipe of the same ordered diameter, heat, wall thickness, and grade shall be given. Heat and product analyses shall be performed wherein steel pipes shall conform to the required chemical composition for carbon, sulfur, and phosphorus. Steel samples shall undergo tension test and shall conform to tensile properties such as yield strength and tensile strength. Hydrostatic pressure test shall be performed for steel samples with specified wall thickness and test pressure. The entire outer surface of the steel pipe shall undergo nondestructive electric test and shall be inspected for longitudinal defects by either magnetic particle inspection, ultrasonic inspection, and electromagnetic inspection.
This abstract is a brief summary of the referenced standard. 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. 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.
1.1 This specification covers seamless, black, plain-end steel pipe for use in the conveyance of fluids under pressure. Pipe in sizes NPS 1 to 26, inclusive, as given in ASME B36.10M is included. Pipe having other dimensions, in this size range, may be furnished provided such pipe complies with all other requirements of this specification.
1.2 It is intended that the pipe be capable of being circumferentially welded in the field when welding procedures in accordance with the requirements of the applicable pipeline construction code are used.
1.3 The values stated in either inch-pound units or in SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values in each system are not exact equivalents; therefore, each system is to be used independently of the other.
