Note:NR indicate the unadvisable application 　　Non-critical state:FRP pipe is not applicable to the transportion of CO2 in ultral state. 　　The table provide the references for the application of high-pressure FRP pipe and the common chemical resistance index of the highpressure FRP pipe. The influences of chemical compounds,thermodynamics,associated loading and stress are not considered.The highest temperature in the table is based on the newly announced experimental results of laboratory,practical application in oil-field and the data from raw material providers.
