For high-temperature and high-pressure boiler units, the parameters of the fresh steam at the boiler outlet are 9.81 MPa and 540 degrees. When selecting pipes for these applications, 12CrlMoV (GB5310-85) with specifications of 9.81 MPa and 540 degrees is chosen. How should the design margin for such pipes be determined? Please advise, experts
