Embonini yokukhiqiza nokulungisa izingxenye zezimoto, amasistimu amapayipi asebenza njengemoto eyinhloko yokudlulisa uketshezi, futhi ukwethembeka kwabo kuthinta ngokuqondile ukusebenza kwemishini nokuphepha kokukhiqiza. Kuyo yonke le minyaka yokuqongelela kobuchwepheshe kanye nesipiliyoni somkhakha, ngifingqe okuhlangenwe nakho okumbalwa okubalulekile ekwakhiweni, ukufakwa, nokugcinwa kwamapayipi ezingxenye zezimoto, okunganikeza ireferensi kubasebenzi bemboni.
Ukukhetha okubalulekile kubalulekile. Amapayipi ezingxenye ezizenzakalelayo kufanele amelane nengcindezi ephezulu, izinga lokushisa eliphezulu, noma imidiya ebolayo (njengesipholisa kanye nesithambisi) isikhathi eside, ngakho okokusebenza kufanele kuhambisane nezimo ezithile zokusebenza. Isibonelo, amapayipi e-aluminium alloy anesisindo esincane futhi ayagqwala,{2}}ayikwazi ukumelana nokugqwala, okuyenza ifanelekele amasistimu okupholisa enjini, kuyilapho i-stainless steel piping ifaneleka kakhulu{3}}olayini bakawoyela ocindezelayo noma izindawo eziyingozi kakhulu. Naka ukunaka okukhethekile ekubalweni kobukhulu bodonga lwamapayipi. Ukuzaca kakhulu kungaholela kalula ekuqhekekeni, kuyilapho ukuqina kakhulu kwandisa izindleko nobunzima bokufaka. Empeleni, ukusetshenziswa kabi kwepayipi elivamile le-carbon steel ukuthutha isulfure{7}equkethe okokupholisa kubangele ukubhobozwa nokuvuza phakathi nezinyanga ezintathu. Ukushintshela ku-316L yensimbi engagqwali kuyixazulule ngokuphelele inkinga.
Inqubo yokufaka inquma ukuphila kwamapayipi. Ukuvalwa kokuxhunywa kwamapayipi kubaluleke kakhulu. Izixhumanisi ze-flange kufanele ziqondaniswe ngokuqinile futhi ziqiniswe ku-torque evamile kusetshenziswa isikrufu se-torque ukugwema ukugxila ekucindezelekeni. Izinqubo zokushisela kufanele zingabi nama-pores kanye ne-slag inclusions, futhi ukuhlolwa kwe-X{3}}kubaluleke kakhulu kumapayipi{4}}omfutho ophezulu. Ngesikhathi sokufakwa kwepayipi lamabhuleki emoto, irediyasi encane yokugoba ibangele ukwanda kokumelana noketshezi, okugcine kubangele ukwehluleka ukubambezeleka kwebhuleki. Le nkinga yabe isiqedwa ngokuthuthukisa imingcele yokugoba (indawo encane yokugoba Inkulu noma ilingana nezikhathi ezi-3 zobubanzi bepayipi). Ngaphezu kwalokho, isikhala sokusekela amapayipi kufanele sibalwe ngokusekelwe kububanzi bepayipi nesisindo soketshezi. Ukuvala isikhala kakhulu kwandisa izindleko, kuyilapho ukuncipha kakhulu kwesikhala kungase kubangele ukwaphuka kokuvevezela kokukhathala.
Amasu okunakekela adinga ukulungiswa okunamandla. Njalo uhlole amapayipi ukugqwala okungaphezulu, amajoyinti axegayo, namadiphozithi okungcola okuwuketshezi, bese usungula uhlelo lokuvimbela lokubuyisela olusekelwe esikhathini sokusebenza. Isibonelo, amapayipi erabha kufanele ashintshwe njalo ngemva kweminyaka engu-2-3, ngisho noma ungekho umonakalo obonakalayo. Ngoxhumo lwe-clamp ezindaweni zokudlidliza ezinemvamisa ephezulu, kuyanconywa ukuthi uhlole kabusha isimo sokuqiniswa njalo ngamahora angama-500. Ukusetshenziswa kwamathuluzi edijithali (njengokuqapha okunenethiwekhi kwezinzwa zomfutho wephayiphi) kunganikeza isexwayiso sangaphambi kwesikhathi sezingozi zokuvuza futhi kunciphise ngokuphawulekayo amathuba okuhluleka okuzumayo.
Ukuthuthukisa amasistimu wamapayipi ezingxenye ze-auto akuyona-inqubo yokudubula eyodwa; idinga inhlanganisela yesayensi yezinto, izinqubo zobunjiniyela, kanye nempendulo yedatha. Kuphela ngokunaka ngokucophelela imininingwane kanye nokwenza ngcono okuqhubekayo singakwazi ukuzuza ibhalansi phakathi kokuphepha, ukusebenza kahle, nokulawulwa kwezindleko.
