Standard Specification for SEAMLESS CARBON STEEL PIPE FOR HIGH-TEMPERATURE SERVICE
|Publication Date:||1 November 2011|
This specification2 covers seamless carbon steel pipe for high-temperature service (Explanatory Note 1) in NPS Va to NPS 48 inclusive, with nominal (average) wall thickness as given in 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 (Explanatory Note 2)
Supplementary requirements (Sections S1 to S4) of an optional nature are provided for seamless pipe intended for use in applications where a superior grade of pipe is required. These supplementary requirements call for additional tests to be made and when desired shall be so stated in the order.
When these products are to be used in applications conforming to ISO Recommendations for Boiler Construction, the requirements of Specification A 520 (Section 2) shall supplement and supersede the requirements of this specification.
The values stated in inch-pound units are to be regarded as the standard.
NOTE 1-The dimensionless designator NPS (nominal pipe size) has been substituted in this standard for such traditional terms as "nominal diameter", "size", and "nominal size",
