1. Imigaqo esisiseko yokukhetha i-hardfacing
l Ukuqinisekisa ukuxhathisa okufanelekileyo kunye nokukhusela ngcono izixhobo ze-downhole ezifana nokudityaniswa kwemibhobho yokomba, imibhobho yokubhobhoza enobunzima, kunye neekhola zokomba. Ubunzima bomphezulu bebhanti elikwaziyo ukunxiba akufunekanga libe ngaphantsi kwe-HRC55.
l Xa ubhobhoza kwi-casing, ukwenzela ukukhusela i-casing kunye nokunciphisa ukunxiba kwayo, ibhanti ekhethiweyo yokunxiba kufuneka ibe nokusebenza kakuhle kwe-friction.
l Ulungelelwaniso olufanelekileyo ngokwenzululwazi phakathi kokumelana nokunxiba kunye nokunciphisa ukukhuhlana.
l Ngokuqhelekileyo, kucetyiswa ukuba kusetyenziswe i-hardfacing ngesimo "esiphakanyisiweyo", kwaye akukhuthazwa ukusebenzisa i-hardfacing kunye ne-"flat" shape. Kuphela xa ubuninzi bangaphandle bombhobho wokudibanisa umbhobho we-drill bukhawulelwe ukuphepha ukuphazamiseka kwi-diameter yangaphakathi ye-casing, kucetyiswa ukuba kusetyenziswe i-"flat" ehambelanayo yokugqoka i-strip-resistant strip. Naluphi na uhlobo lomgca ongagugiyo odityaniswe ngolu hlobo alukwazi ukuvelisa isiphumo esiphezulu sokungagugi ngenxa yokuba zombini i-diameter yangaphandle yombhobho we-drill joint kunye ne-strip-resistant strip inxiba ngexesha elinye.
2. Iingcamango eziphosakeleyo eziqhelekileyo ekukhetheni i-hardfacing
Ukungaqondi kakuhle 1:Ibhanti le-Tungsten carbide elikwaziyo ukunxiba lelona bhanti ligqwesileyo linganxibi elisetyenziselwa ukukhusela iintonga zokomba
Emva kokuba umcu we-tungsten carbide onganyangekiyo udityaniswe kwidibano yombhobho wokubhoboza, amasuntswana abukhali e-tungsten carbide abangela ukusika kancinci kwi-casing, okukhokelela ekunxityweni okukhulu kwecasing.
Iinkampani ezininzi zeoli zangaphandle zinemigangatho yangaphakathi evimbela ngokucacileyo ukusetyenziswa kwe-tungsten carbide hardfacing. Eminye imimandla yeoli yasekhaya iyakwalela ukusetyenziswa kwayo.

Ukungaqondi kakuhle 2: Ukukhetha ubuso obunzima obulandela ngokugqithisileyo ukunciphisa ingxabano kunye nokumelana nokuncama ukunxiba
l Ukuze kukhuseleke i-casing kunye nokunciphisa ukunxiba kwayo, ukulandela ngokugqithiseleyo ukusebenza kwe-anti friction yebhanti engagugiyo ibingelela ukuxhathisa kwayo.
ü Ibhanti elingagugiyo liguga ngokulula, libangela ukudibana ngokuthe ngqo phakathi kombhobho we-drill joint kunye ne-casing okanye iqula lokubumba. Njengoko kwaziwa kakuhle, ukunxiba phakathi kombhobho wokugrumba ongenanto kunye ne-casing okanye iqula lokubumba kukhulu kakhulu kunolo lombhobho wokubhoboza odityaniswe nebhanti ekwaziyo ukunxitywa, okukhokelela ekuguqweni okukhulu kwe-casing kunye nokusilela kwangoko kombhobho wokubhoboza. ngenxa yokunxiba okugqithisileyo.
ü Ubomi obufutshane benkonzo yobulukhuni bonyusa iindleko zabo zokusetyenziswa.
