Ipayipi lensimbi elingenamthungo eligoqelwe ngokushisayo elisuka eshubhuni liye emkhiqizweni ngokuvamile lidinga ukufudumeza okubili, okuyishubhu elinezimbobo ngaphambi nangemuva kokushisisa nokugingqa ububanzi bepayipi elingenalutho endaweni yokushisisa kwangaphambilini;ukukhiqizwa kokugoqa okubandayo (ukudonsa) lapho ipayipi idinga ukusetshenziswa kwe-annealing ephakathi ukuze kuqedwe ukucindezeleka okusele;insimbi yezinye izidingo ezikhethekile, ukuze kuthuthukiswe izakhiwo zemishini yepayipi lensimbi futhi kuthuthukiswe ukusebenza kwenhlangano nenqubo, kodwa futhi nokwelashwa kwayo kokushisa.Ishubhu elivamile (ipayipi) lokushisisa lilimaza ukushisisa okungalingani, i-oxidation, i-decarbonization, imifantu yokufudumeza, ukushisa ngokweqile, ukushisa ngokweqile.

Ishubhu elinembobo elishisayo ngaphambili, futhi inhloso yalo ukuthuthukisa i-ductility;ukunciphisa insimbi yokumelana ne-deformation;ukunikeza microstructure enhle iyagoqa.Kukhona isithando somlilo se-annular, isithando somlilo esishisa kabusha, iziko ezithambekele eziko kanye nesithando somlilo esingaphansi kwemoto.Njengoba kunikezwe ukushoda kwe-diameter yepayipi ngaphambi kokushisa kabusha, okuhloswe ukwandisa izinga lokushisa kwe-tube kanye nokushoda okufanayo kanye nokuthuthukisa i-ductility yensimbi, ukulawula i-microstructure yayo, ukudala izimo ezivumayo zokulinganisa ipayipi likamama futhi uqinisekise izakhiwo zensimbi zensimbi.Uhlobo olujwayelekile lwesithando somlilo esishisisa kabusha isithando somlilo, isithando somlilo esiqhubekayo esishisisa isithando somlilo, ihhashi lomlilo elitshekile, isithando somlilo esishisayo.Cold-rolled (donsa) reheating ukuqina ikakhulukazi ukuqeda, ukunciphisa deformation ukumelana.Isithando somlilo esivamile sisetshenziswa kakhulu ekushisiseni kabusha isithando somlilo, isithando somlilo esingaphansi kwemoto, isithando somlilo esiqhubekayo se-roller.Ekukhiqizeni amashubhu ensimbi angenamthungo, isithando somlilo se-annular kanye nesithando somlilo esishisayo okwamanje sisetshenziswa kakhulu;isithando somlilo sokungenisa ugesi siyathuthukiswa;kuthambekele eziko bafudumale isithando ngoba izinga akuyona okusezingeni eliphezulu, umsebenzi omkhulu futhi ivame ukuba iqedwe.Isithando somlilo esiqhubekayo se-roller sisetshenziswa ikakhulukazi ekugoqeni okubandayo (ukudonsa) ukwelashwa kokushisa kwensimbi;isithando somlilo esingaphansi kwemoto esilungele amaqoqo amancane, isikhathi sokwelashwa kokushisa side ukufudumeza kanye nokufakwa kwepayipi lensimbi eliwugqinsi elinezindonga;Igesi evikelayo eqhubekayo yesithando somlilo somlilo isetshenziswa kakhulu endaweni yensimbi idinga ukwelashwa okushisa kanye nensimbi eqediwe ebandayo ngaphandle kwe-oxidation (ukudonsa) phakathi nenqubo yokukhetha i-annealing.
