Amapayipi ensimbi angenamthungo anobubanzi obukhulu anobubanzi obukhulu enziwa ngezinsimbi zensimbi noma insimbi eyisiyingi eyindilinga ebhodlozwa ibe amashubhu e-capillary bese igoqwa ngokushisa. Amapayipi ensimbi angenamthungo anobubanzi obukhulu anobubanzi obukhulu adlala indima ebalulekile embonini yamapayipi ensimbi yezwe lami. Ngokwezibalo ezingaphelele, bangaphezu kwama-240 abakhiqizi bamapayipi angenamthungo ezweni lami kanye namayunithi amapayipi ensimbi angenamthungo anobubanzi obukhulu obungububanzi obungu-250. Amapayipi ensimbi angenamthungo anobubanzi obukhulu anobubanzi obukhulu asekelwe kububanzi bangaphandle bepayipi lensimbi. Ngokuvamile, lezo ezinobubanzi obungaphandle obungaphezu kuka-325 mm zibizwa ngokuthi amapayipi ensimbi anobubanzi obukhulu. Ngokuqondene nezindonga eziwugqinsi, ngokuvamile, lezo ezinodonga olungaphezu kuka-20 mm zanele. Okulandelayo inqubo yokukhiqiza amapayipi ensimbi: Impahla yamapayipi ensimbi izikhala zamapayipi ensimbi. Izikhala zamapayipi zidinga ukusikwa ngomshini wokusika zibe ngenalutho ubude obuyimitha elingu-1.

Futhi ithunyelwe esithandweni ukuze kushiswe ngebhande lokuhambisa. I-billet ifakwa esithandweni futhi ishiselwe ekushiseni okungaba ngu-1200°C. Uphethiloli yi-hydrogen noma i-acetylene. Ukulawulwa kwezinga lokushisa esithandweni kuyinkinga ebalulekile. Ngemuva kokuthi ishubhu eliyindilinga liphuma esithandweni, kufanele libhobozwe ngomshini wokubhoboza ingcindezi. Ngokuvamile, umshini wokubhoboza ovame kakhulu umshini wokubhoboza we-tapered. Lolu hlobo lomshini wokubhoboza lusebenza kahle kakhulu ekukhiqizeni, ikhwalithi yomkhiqizo omuhle, ukunwetshwa kobubanzi obukhulu be-perforation, futhi kungangena ezinhlobonhlobo zensimbi. Ngemva kokubhobozwa, ishubhu eliyindilinga elingenalutho liyagoqwa ngokulandelana, ligoqwe ngokuqhubekayo, noma likhishwe ngama-roller amathathu. Ngemuva kwe-extrusion, ipayipi kufanele isuswe futhi ilinganiswe. Umshini wokulinganisa uzungezisa umgodi ocijile ngesivinini esikhulu ungene endaweni engenalutho yensimbi ukuze ubhoboze izimbobo zokwenza ipayipi lensimbi. Ububanzi bangaphakathi bepayipi lensimbi bunqunywa ubude be-diameter yangaphandle ye-drill bit yomshini wokulinganisa. Ngemva kokuba ipayipi lensimbi lilinganiselwe, lingena embhoshongweni wokupholisa futhi lipholiswe ngokufafaza amanzi. Ngemva kokuba ipayipi lensimbi selipholile, lizoqondiswa (empeleni, abakhiqizi abaningi abasasebenzisi imishini yokuqondisa, kodwa baqondise ngokuqondile ipayipi lensimbi ngemva kokudlula emshinini wokugoqa. Ifinyelele ekuqondeni kwepayipi layo lensimbi ngokwayo). Ngemva kokuqondisa, ipayipi lensimbi lithunyelwa kumtshina wensimbi (noma ukuhlolwa kwe-hydraulic) ngebhande lokudlulisa ukuze kutholwe amaphutha angaphakathi. Uma kukhona ukuqhekeka, amabhamuza, nezinye izinkinga ngaphakathi kwepayipi lensimbi, zizotholwa. Ngemuva kokuhlolwa kwekhwalithi, amapayipi ensimbi kufanele akhethwe ngesandla ngokuqinile (manje wonke anokuhlolwa kokutholwa kwe-laser).
