This International Standard specifies minimum requirements and gives guidance for the design and installation of new piping systems on production platforms located offshore for the petroleum and natural gas industries. It covers piping systems up to 69 000 kPa (ga) maximum, within temperature range limits for the materials meeting the requirements of ASME B31.3. NOTE For applications outside these pressure and temperature ranges, this International Standard may be used but special consideration should be given to material properties. Annex A gives some worked examples for solving piping design problems.
