Description / Abstract:
This specification2
covers seamless carbon steel pipe for high-temperature service
(Note 1) in NPS 1⁄8 to NPS 48 [DN 6 to DN 1200] (Note 2) inclusive,
with nominal (average) wall thickness as given in ASME B 36.10M. It
shall be permissible to furnish pipe having other dimensions
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 1—It is suggested, consideration
be given to possible graphitization.
NOTE 2—The dimensionless designator NPS (nominal pipe size) [DN
(diameter nominal)] has been substituted in this standard for such
traditional terms as “nominal diameter,” “size,” and “nominal
size.”
Supplementary requirements 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.
The values stated in either SI units or inch-pound units are to
be regarded separately as standard. The values stated in each
system may not be exact equivalents; therefore, each system shall
be used independently of the other. Combining values from the two
systems may result in non-conformance with the standard.
The following precautionary caveat pertains only to the test
method portion, Sections 11, 12, and 13 of this
specification:This standard does not purport to address all of
the safety concerns, if any, associated with its use. It is the
responsibility of the user of this standard to establish
appropriate safety and health practices and determine the
applicability of regulatory limitations prior to use.

and Pressure Vessel Code applications see related Specifications
