Iziphambeko eziyinhloko zekhwalithi yamapayipi ensimbi abandayo ahlanganisa: ubukhulu bodonga olungalingani, ububanzi obungaphandle bokubekezelelana, ukuqhekeka kwendawo, imibimbi, ukugoqa, njll.
① Ukuthuthukisa ukunemba kokuqina kodonga lweshubhu elingenalutho kuyisimo esibalulekile sokuqinisekisa ukujiya kodonga olufanayo lwamapayipi ensimbi agoqelwe ngokubanda.
② Ukuqinisekisa ukunemba kokuqina kodonga kanye nekhwalithi yokukhetha yeshubhu elingenalutho, ikhwalithi yokuthambisa kanye nokuqedwa kwangaphezulu kwethuluzi lokugoqa ishubhu kuyiziqinisekiso ezibalulekile zokuthuthukisa ukunemba kodonga lweshubhu eligoqiwe elibandayo. Ukucofa ngokweqile noma ukucoshwa kancane kweshubhu elingenalutho kufanele kugwenywe, futhi indawo engenalutho yeshubhu kufanele ivinjwe ukuthi ingacolisiswa kakhulu noma ingacoshwa kancane. Uma i-pitting noma isikali se-iron oxide esisele sikhiqizwa, qinisa ukupholisa kwamathuluzi okugingqa amapayipi kanye nokuhlolwa kwekhwalithi yendawo yamathuluzi, bese ushintsha ngokushesha izinti ze-mandrel namabhulokhi agingqikayo.
③ Zonke izinyathelo zokunciphisa amandla okugoqa zisiza ekuthuthukiseni ukunemba kobubanzi bangaphandle bepayipi lensimbi, okuhlanganisa ukuvala ishubhu elingenalutho, ukunciphisa inani lokuguquguquka, ukuthuthukisa ikhwalithi yokugcoba ye-tube engenalutho kanye nokuqedwa kwe-tube rolling. ithuluzi, njll., kusetshenziswa Sebenzisa izinto ezisetshenziswayo ezinamandla amakhulu nobulukhuni ukwenza amathuluzi okugingqa amapayipi, futhi uqinise ukupholisa nokuhlolwa kwamathuluzi okugingqa amapayipi. Uma amathuluzi okugoqa amapayipi etholakala ukuthi agqoke kakhulu, kufanele ashintshwe ngesikhathi ukuze kuvinjelwe ububanzi obungaphandle bepayipi lensimbi ukuba budlule ukubekezelelana.
④ Imifantu ebusweni bamapayipi ensimbi akhiqizwa ngesikhathi sokugoqa okubandayo abangelwa ukuwohloka okungalingani kwensimbi. Ukuze uvimbele ukuqhekeka kwendawo epayipini lensimbi ngesikhathi sokugoqa okubandayo, i-tube blank kufanele ifakwe uma kunesidingo ukuze kuqedwe ukuqina komsebenzi wensimbi futhi kuthuthukiswe ipulasitiki yensimbi.
⑤ Inani le-deformation eginqikayo linomthelela obalulekile emifantwini engaphezulu yamapayipi ensimbi agoqeke abandayo. Ukuncishiswa okufanele kwe-deformation kuyindlela ephumelela kakhulu yokunciphisa imifantu engaphezulu yamapayipi ensimbi.
⑥ Ukuthuthukisa indawo engaphezulu yamathuluzi okugingqa amapayipi kanye nekhwalithi yokuthambisa yezikhala zamapayipi kuyizinyathelo ezisebenzayo zokuvikela ukuqhekeka kwamapayipi ensimbi.
⑦ Ngokufaka i-annealing kanye nokushisa ukuphatha ishubhu elingenalutho ukuze kuncishiswe ukumelana nokuguquguquka kwensimbi, ukunciphisa inani lokuguqulwa, nokuthuthukisa ikhwalithi yamathuluzi okugoqa amashubhu kanye nekhwalithi yokugcoba, njll., kuyazuzisa ukunciphisa ukuvela kwepayipi lensimbi. ukugoqa okugoqayo kanye nokulimala kokuklwebheka.
