Most　of　the　commonly　used　standards　and　codes　for　burst　pressure　prediction　at　a　corrosion　defect　of　steel　pipelines　generally　just　consider　internal　pressure　alone.　However,　an　actual　oil/gas　pipeline　is　usally　subjected　to　external　loads,　such　as　axial　compression/tension　and　bending　moment,　which　may　affect　the　burst　capacity　of　the　pipeline.　In　this　study,　a　three-dimensional　(3D)　nonlinear　finite　element　(FE)　model　validated　by　burst　tests　was　developed　to　investigate　the　effect　of　bending　moment　and　axial　force　on　the　burst　capacity　of　corroded　pipelines.　Subsequently,　the　effects　of　external　loads　(i.e.,　bending　moment,　and　axial　force)　and　corrosion　geometry　features　(involving　corrosion　depth,　width,　length,　and　clock　position)　on　the　pipe　burst　pressure　were　determined.　Then,　based　on　a　series　of　FE　cases,　a　new　burst　prediction　model　for　corroded　pipelines　subjected　to　the　combination　loads　of　bending　load　and　axial　compressive　force　was　fitted　and　developed.　Finally,　the　effectiveness　and　reliability　of　the　new　proposed　model　were　verified　by　extensive　parametric　FE　analysis　and　burst　test　data.　The　results　show　that　the　prediction　errors　for　the　failure　pressures　between　the　proposed-model　and　the　FEM　were　less　than　10%　for　most　92.793%　of　the　222　cases.　Moreover,　the　proposed　model　can　also　be　applied　to　the　condition　that　the　pipeline　is　under　single　internal　pressure,　and　its　prediction　accuracy　is　better　than　that　of　other　seven　well-known　models　of　ASME　B31G,　Mod　B31G　(0.85　d　L),　Z662,　DNV,　PCORRC,　CUP,　and　Shell-92.
