This standard specified the basic technical requirements for stress calculation of steam/water pipes in the thermal power plant. This standard is applicable to the stress calculation of steam/water pipes in the thermal power plants which are being newly built, undergoing expansion or being rebuilt as well as in the thermal plants which take the low carbon steels, low alloy steels and high chrome steels as their piping materials. The stress calculation of the oil/gas media pipes and the non-nuclear pipes of the nuclear power station can refer to this standard.
