Description
This standard applies to seamless tubes 1) including tubes for headers of heat-resistant steels according to Table 1 which are used in the construction of boilers, pipe-lines, pressure vessels and equipment for service up to 600∩ and at simultaneous high pressures, where the tototal stress and the relevant scaling conditions can raise or lower the temperature limit.
