ASTM A660/A660M-21

Standard Specification for Centrifugally Cast Carbon Steel Pipe for High-Temperature Service

ABSTRACT
This specification covers carbon steel pipe made by the centrifugal casting process intended for use in high-temperature, high-pressure service. This pipe shall be suitable for fusion welding, bending, and other forming operations. Grades for carbon steels shall conform to the required chemical composition for carbon, manganese, phosphorous, sulfur, and silicon. Manufacturing of the material shall be done by machining and heat treatment. Pyrometers shall be used to control the furnace temperatures. Tensile properties shall conform to the required values for tensile strength, elongation, and reduction of area. Mechanical properties shall conform to the following: transverse or longitudinal tension test; flattening test; and hydrostatic test.
SCOPE
1.1 This specification2 covers carbon steel pipe made by the centrifugal casting process intended for use in high-temperature, high-pressure service. Pipe ordered under this specification shall be suitable for fusion welding, bending, and other forming operations.  
1.2 Several grades of carbon steels are covered. Their compositions are given in Table 1.    
1.3 Supplementary requirements (S1 to S9) of an optional nature are provided. The supplementary requirements call for additional tests to be made, and when desired shall be so stated in the order, together with the number of such tests required.  
1.4 The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be used independently of each other. Combining values from the two systems may result in nonconformance with the specification.  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
