Izinzuzo ze-spiral welded pipe:
(1) Amadayamitha ahlukene amapayipi ensimbi ezungezayo angakhiqizwa ngekhoyili enobubanzi obufanayo, ikakhulukazi amapayipi ensimbi anobubanzi obukhulu angakhiqizwa ikhoyili yensimbi encane.
(2) Ngaphansi kwesimo esifanayo sokucindezela, ukucindezeleka komthungo wokushisela okuvunguzayo kuncane kunalowo womthungo wokushisela oqondile, okungama-75% ~ 90% alowo wepayipi elishiselwe umthungo oqondile, ukuze ukwazi ukuthwala ukucindezela okukhulu.Uma kuqhathaniswa nepayipi elishiselwe eliqondile elinobubanzi obufanayo bangaphandle, ukushuba kodonga lwepayipi elishiselwe okuvunguza kungancishiswa ngo-10% ~ 25% ngaphansi kwengcindezi efanayo.
(3) Ubukhulu bunembile.Ngokuvamile, ukubekezelela ububanzi akukho ngaphezu kwe-0.12% futhi i-ovality ingaphansi kwe-1%.Izinqubo zokulinganisa nokuqondisa zingashiywa.
(4) Ingakhiqizwa ngokuqhubekayo.Uma sikhuluma nje, ingakhiqiza ipayipi lensimbi elingapheli elinekhanda elincane nokulahlekelwa umsila, futhi lingathuthukisa izinga lokusebenzisa insimbi ngo-6% ~ 8%.
(5) Uma kuqhathaniswa nepayipi elishiselwe ngomthungo oqondile, linokusebenza okuguquguqukayo kanye noshintsho olulula nokulungiswa kwezinhlobonhlobo.
(6) Isisindo sempahla elula kanye nokutshalwa kwezimali kokuqala okuncane.Ingenziwa ibe yiyunithi yeselula yohlobo lwe-trailer ukukhiqiza amapayipi ashiselwe ngqo endaweni yokwakha lapho amapayipi abekwe khona.
Ububi bepayipi elishiselwe okuvunguzayo yilezi: ngenxa yokusetshenziswa kwensimbi egoqiwe njengezinto ezingavuthiwe, kukhona ijika elithile le-crescent, futhi indawo yokushisela isendaweni enqenqemeni yensimbi, ngakho-ke kunzima ukuvumelanisa isibhamu sokushisela futhi kuthinte izinga lokushisela.Ngakho-ke, ukulandelela i-weld eyinkimbinkimbi kanye nemishini yokuhlola ikhwalithi kufanele kumiswe.
