YANG Huachun;LI Jian;ZENG Fanwei;WU Shiqiang;XIE Xiaoyuan;LAI Xianhong;YANG Wen;DEC Dongfang Boiler Group Co.,Ltd.;  
With consideration of the development trend of the thermal power plant-used boiler,described here in the paper are the R D orientation of the high-parameter hi-pressure boiler pipe/tube, and the new type heatresistant steel grades which are probably used in near future for boiler pipes/tubes, i.e., G115、 SAVE12AD、VM12-SHC、 Sanicro25 and SP2215. Also analyzed are the typical problems concerning quality of the hi-pressure boiler pipe/tube to which all the related industries need to pay close attention in their engineering practices,including the local soft area of the large-sized hi-pressure boiler pipe/tube and the inner surface linear defects of the small-sized hi-pressure boiler pipe/tube, defective deformation and end-folding of the hot-rolled boiler pipe/tube as well as the inner surface oxidation of the austenitic heat-resistant steel pipe/tube,etc.
