In　view　of　the　inaccuracy　of　the　traditional　leakage　location　method　caused　by　the　interaction　between　the　leakage　noises　at　leakage　points,　a　multi-leakage　point　location　algorithm　based　on　iterative　recursion　was　developed.　The　influences　of　the　threshold　signal　to　noise　ratio　and　the　iteration　termination　condition　on　the　performance　of　the　algorithm　were　analysed,　and　the　input　parameters　were　optimized.　The　experiments　results　prove　that　the　algorithm　can　be　used　to　estimate　the　number　and　position　of　leakage　points　in　a　pipeline,　with　an　error　less　than　1　m.　The　study　provides　a　feasible　solution　for　the　detection　and　location　of　multiple　leakage　points　in　practical　engineering　pipelines.　©　2020,　Editorial　Office　of　Journal　of　Vibration　and　Shock.　All　right　reserved.
