This specification covers seamless carbon steel pipe for high-temperature service (Note 1) in NPS 1/8 to NPS 48 inclusive, with nominal 9average0 wall thickness as given is ANSI B36.10. Pipe having other dimensions may be furnished provided such pipe complies with all other requirements of this specification. Pipe ordered under this specification shall be suitable for bending, flanging, and similar forming operations, and for welding. When the steel is to be welded, it is presupposed that a welding procedure suitable to the grade of steel and intended use or service will be utilized (Note 2).
NOTE 1: Consideration should be given to possible graphitization of the material at the higher temperatures at which it may be used.
NOTE 2:Grades A rather than Grades B or Grades C pipe should be used for close coiling, or cold bending.
