1. Izimiso eziyisisekelo zokukhetha i-hardfacing
l Ukuqinisekisa ukumelana nokugqokwa okuhle nokuvikela kangcono amathuluzi omgodi wokubhoboza njengamajoyinti amapayipi okubhoboza, amapayipi okubhola anesisindo, namakholola okubhoboza. Ukuqina kwendawo yebhande elimelana nokuguga akumele kube ngaphansi kune-HRC55.
l Uma ubhoboza ku-casing, ukuze uvikele i-casing futhi unciphise ukuguga kwayo, ibhande elikhethiwe elimelana nokugqoka kufanele libe nokusebenza okuhle kwe-anti friction.
l Ibhalansi enengqondo ngokwesayensi phakathi kokumelana nokuguga nokunciphisa ukushwibeka.
l Ngokuvamile, kunconywa ukusebenzisa i-hardfacing ngesimo "esiphakanyisiwe", futhi akunconywa ukusebenzisa i-hardfacing ngesimo "esicaba". Kuphela uma ubukhulu bangaphandle be-diameter obuhlangene bepayipi lokubhoboza bukhawulelwe ukuze kugwenywe ukuphazamiseka kobubanzi bangaphakathi be-casing, kunconywa ukuthi usebenzise umucu omelana nokuguga onomumo "oyisicaba". Noma yiluphi uhlobo lomucu ongagugi oshiselwe ngale ndlela alukwazi ukukhiqiza umphumela omkhulu ongagugi ngoba kokubili ububanzi bangaphandle bejoyinti lepayipi lokubhoboza kanye nomucu ongagugi kugqokwa ngesikhathi esisodwa.
2. Imibono eyiphutha evamile ekukhetheni i-hardfacing
Umbono oyiphutha 1:Ibhande le-tungsten carbide elimelana nokugqokwa liyibhande elingcono kakhulu elingagqoki elisetshenziselwa ukuvikela izinduku zokubhoboza
Ngemva kokuba umugqa ongagugi we-tungsten carbide usushiselwe ekuhlanganyeleni kwepayipi lokubhoboza, izinhlayiya ezibukhali ze-tungsten carbide zidala ukusikwa okuncane ku-casing, okuholela ekugugeni okunzima kwe-casing.
Izinkampani eziningi zikawoyela zakwamanye amazwe zinezindinganiso zangaphakathi ezivimbela ngokusobala ukusetshenziswa kwe-tungsten carbide hardfacing. Amanye amasimu kawoyela asekhaya nawo ayakwenqabela ukusetshenziswa kwawo.
I-NS-1 ejwayelekile
Izindinganiso zangaphakathi ze-P Oil Company e-UK
Umbono oyiphutha 2: Ukukhetha i-hardfacing ephishekela ngokweqile ukunciphisa ukungqubuzana nokumelana nokugqoka kokuzinikela
l Ukuze kuvikelwe i-casing futhi kuncishiswe ukuguga kwayo, ukuphishekela ngokweqile ukusebenza kwe-anti friction yebhande elingagugi kudela ukumelana nokuguga.
ü Ibhande elingagugi liguga kalula, libangele ukuthintana okuqondile phakathi kwejoyinti lepayipi lokubhoboza kanye ne-casing noma i-wellbore yokwakha. Njengoba kwaziwa kahle, ukuguga phakathi kwejoyinti lepayipi lokubhoboza elingenalutho kanye ne-casing noma ukwakhiwa komthombo kukhulu kakhulu kunokuhlanganiswa kwepayipi lokubhoboza elinebhande elingagugi, okuholela ekugugekeni okukhulu kwekheshi kanye nokwehluleka ekuqaleni kwepayipi lokubhoboza. ngenxa yokugqoka ngokweqile.
ü Impilo emfushane yesevisi ye-hardfacing inyusa izindleko zabo zokusebenzisa.
