机械式外割刀WD-J型机械外割刀，常与套铣管连接，能快速有效地从管子外面割断和取出切下的管子。适用于从管外切割的套管、油管和钻杆等。它采用弹簧自动进给在管外进行切割管材的割刀。由于弹簧自动进给，它可避免由于司钻操作失误过大拉力而毁坏割刀，割断后可与落鱼同时起出，该割刀可5″和41/2″钻杆，在切割不同钻杆时，需要更换相应的卡紧套。MechanicalexternalcutterTheMechanicalexternalcutterwhichoftenconnectswithwashoverpipe,isusedtocutandremovestuckpipeinlongundamagedsecti***,andcapableofcuttingalltypesofstuckdrillpipeortubingorcasing.Theexternalcutterutilizedautomaticspring-fedtocuttubingattheoutsideofthepipe.Asaresultofautomaticspring-fed,itcanbe***oidedexertingoverpullingforcetodamagecuttercausedbyheaddriller’fault.Aftercuttingitcanbeliftedwithfishatthesametime.Thecuttercanbecut5″and41/2″drillingpipe.Whencuttingdifferentpipes,itwouldbechangedproperclampingcasing.ThemechanicalexternalCutterissimpleinstructure,safeandreliableinuse,convenientoperation,high-efficiencyperformance.Thecutterworks***oothly,rapidlyandiswidelyusedincuttingblockedoilrodeorrecuttingbrokencatchinwell.Ithasbeenproventobethemostversatileandreliableinthefield.机械式外割刀技术参数SpecificationofMechnicalExternalCutter型号Type外径O.D.(mm)内径I.D.(mm)切割管外径O.D.ofCuttingPipe(mm)***大落物外径MaxO.D.ofFish(mm)接头螺纹ConnectionAPI适用井径SuitableWellDiameter(in)WD-J58584133.439.423/8″TBG62.0WD-J989879607823/8″TBG105.0WD-J114114826079NC26120.6WD-J119119987395NC26125.4WD-J14314311152、89108NC31146.2WD-J14914911760、89114NC31155.6WD-J15415412460、101120NC38158.8WD-J19419416289、101、114、12715965/8″REG209.5WD-J206206168101、14616565/8″REG219.0)
