Ipayipi lensimbi elivunguzayo lisetshenziswa kakhulu kuphrojekthi yamanzi kampompi, imboni ye-petrochemical, imboni yamakhemikhali, imboni yamandla kagesi, ukuchelela ngenkasa kwezolimo kanye nokwakhiwa kwamadolobha.Ingenye yemikhiqizo engu-20 ebalulekile eyakhiwe eChina.
Ipayipi lensimbi elivunguzayo lingasetshenziswa ezimbonini ezahlukene.Ikhiqizwa ngokuvumelana nezinqubo ezithile zokucubungula kanye nokukhiqiza futhi idlala indima ebalulekile ekwakheni isakhiwo.Ngokukhula kwengcindezi kanye nokwenyuka kwesisekelo sesevisi enokhahlo, kuyadingeka ukwelula impilo yesevisi yepayipi ngangokunokwenzeka.
Isiqondiso esikhulu sokuthuthukiswa kwepayipi lensimbi elivunguzayo yile:
(1) Dizayina futhi ukhiqize amapayipi ensimbi anesakhiwo esisha, njengamapayipi ensimbi anezingqimba ezimbili ezisontekile.Ingamapayipi anengqimba ephindwe kabili ashiselwe nge-strip steel, sebenzisa ukujiya kwengxenye yodonga lwamapayipi avamile ukuze ashiselwe ndawonye, azoba namandla aphezulu kunamapayipi ongqimba olulodwa anogqinsi olufanayo, kodwa ngeke abonise ukwehluleka ukubola.
(2) Ukuthuthukisa ngamandla amapayipi amboziwe, njengokumboza udonga lwangaphakathi lwepayipi.Lokhu ngeke nje kwandise impilo yesevisi yepayipi yensimbi, kodwa futhi kuthuthukise ukushelela kodonga lwangaphakathi, ukunciphisa ukumelana noketshezi lwamanzi, ukunciphisa i-wax nokungcola, ukunciphisa inani lokuhlanza, bese unciphisa izindleko zokugcinwa.
(3) Thuthukisa amamaki ensimbi amasha, uthuthukise izinga lobuchwepheshe lenqubo yokuncibilikisa, futhi wamukele kabanzi inqubo yokwelapha ukushisa okulawulwayo kokugingqika nokuginqika, ukuze kuthuthukiswe ngokuqhubekayo amandla, ukuqina nokusebenza kokushisela komzimba wamapayipi.
Ipayipi lensimbi elinobubanzi obukhulu limbozwe ngepulasitiki ngesisekelo sepayipi elishiselwe elinobubanzi obuvunguzayo kanye nepayipi elishiselwe imvamisa ephezulu.Ingafakwa nge-PVC, i-PE, i-EPOZY nezinye izimbobo zepulasitiki zezakhiwo ezahlukene ngokwezidingo ezihlukene, ngokunamathela okuhle nokumelana nokugqwala okuqinile.I-asidi eqinile, i-alkali namanye amakhemikhali ukumelana nokugqwala, okungewona ubuthi, akukho ukugqwala, ukumelana nokugqokwa, ukumelana nomthelela, ukumelana okuqinile kokuqina, ipayipi elibushelelezi, akukho ukunamathela kunoma iyiphi into, kunganciphisa ukumelana nezinto zokuhamba, kuthuthukise izinga lokugeleza nezokuthutha. ukusebenza kahle, ukunciphisa ukulahlekelwa kwengcindezi yokudlulisela.Asikho i-solvent ku-coating, ayikho into ye-exudate, ngakho-ke ngeke ingcolise isisetshenziswa sokudlulisa, ukuze kuqinisekiswe ukuhlanzeka nokuhlanzeka koketshezi, ebangeni lika -40 ℃ kuya ku-+80 ℃ ingasetshenziswa ngokushintshana kushisa futhi umjikelezo obandayo, hhayi ukuguga, hhayi ukuqhekeka, ngakho-ke ingasetshenziswa endaweni ebandayo kanye nezinye imvelo enokhahlo.Ipayipi elikhulu lensimbi elihlanganisiwe lisetshenziswa kabanzi emanzini kampompi, igesi yemvelo, i-petroleum, imboni yamakhemikhali, imithi, ukuxhumana, amandla kagesi, ulwandle kanye neminye imikhakha yobunjiniyela.
