A new generation of ultra super-critical stainless steel boiler pipes of 650℃ level produced by TISCO recently passed the technical review held by China Standardization Committee on Boilers and Pressure Vessels. At the same time, T/CISA004-2017, an association standard dominantly constituted by TISCO for new type heat resistant stainless steel (C-HRA-5) seamless pipes for power plant boiler use, also gained approval.
According to various reports TISCO’s newly developed TG700A/B type Ni-based alloy, i.e. the 3rd generation of 700℃ ultra super-critical material for key parts of power station, is now under test in China’s first set of 700℃ power station industrial test platform set up by Huaneng Group.
