I-Spiral Welded Pipe For Fire Pipe Lines
Inzuzo eyinhloko yeipayipi elishiselwe okuvunguzayikhono lokukhiqiza amapayipi ensimbi amadayamitha ahlukene kusuka emicu yobubanzi obufanayo.Lokhu kunenzuzo ikakhulukazi lapho kudingeka imicu emincane yensimbi ukuze kukhiqizwe amapayipi amakhulu ensimbi.Ngaleli khono lokukhiqiza, umkhiqizo unikeza ukuguquguquka okukhulu nokuvumelana nezimo ukuze uhlangabezane nezidingo ezihlukahlukene zamaphrojekthi nezimboni ezahlukene.
Ngaphezu kwalokho, izilinganiso zamapayipi ashiselwe okuvunguzayo anembile kakhulu.Ngokuvamile, ukubekezelelana kobubanzi akudluli ku-0.12%, kuqinisekisa ukuthi ubukhulu bepayipi ngalinye elikhiqizwayo bunembile futhi buhambisana.Leli zinga lokunemba libalulekile ezinhlelweni zokusebenza lapho ubuqotho bobukhulu bubalulekile.

Ngokungeziwe kubukhulu obunembile, ipayipi elishiselwe okuvunguza linikeza ubuqotho obuhle kakhulu besakhiwo.Njengoba ukuchezuka kungaphansi kuka-1/2000, ipayipi libonisa ukuchezuka okuncane ekumeni kwayo kwangempela ngisho nangaphansi kokushintsha kwezingcindezi namandla angaphandle.Lokhu kuqinisekisa ukusebenza okuthembekile nokusebenza kahle, okwenza umkhiqizo ulungele izinhlelo zokusebenza ezibucayi njengamapayipi omlilo.
Ngaphezu kwalokho, i-ovality ye-spiral welded pipe ingaphansi kuka-1%, ithuthukisa ngokwengeziwe ukuqina nokuthembeka kwayo.Lokhu kulawulwa kwe-ovality kubalulekile ezinhlelweni zokusebenza lapho amaphrofayili epayipi ayindilinga angaguquki ebaluleke kakhulu ukuze kugeleze uketshezi olubushelelezi kanye nokusebenza kahle kwesistimu.Ngamapayipi ashiselwe okuvunguza, ikhwalithi nokusebenza kahle kokulethwa kwamanzi noma igesi akuphazamiseki.
Ngokuphawulekayo, inqubo yokukhiqiza amapayipi ashiselwe ayi-spiral iqeda isidingo sezinqubo zokulinganisa nokuqondisa okungokwesiko.Lokhu kubangela ukonga isikhathi esibalulekile nezindleko, okwenza umkhiqizo ukonga kakhulu futhi usebenze kahle.Ngokususa izinyathelo zokukhiqiza ezengeziwe, amakhasimende ajabulela izikhathi zokuhola ezimfushane kanye nezindleko zokukhiqiza ezincishisiwe, okwandisa ukusebenza kahle kwephrojekthi iyonke.
I-spiral welded pipe ifaneleka ngokukhethekileimigqa yamapayipi omlilolapho izidingo eziqinile zokuphepha nokusebenza okuthembekile kubalulekile.Ukunemba kwayo okukhethekile kohlangothi, ubuqotho besakhiwo kanye nokulawulwa kwe-ovality kuyenza ilungele ukuthutha amanzi, igwebu noma ezinye izinto ezicisha umlilo ukuze kuvikelwe impilo nempahla.
Ukwengeza, ipayipi elishiselwe elivunguzayo lilungele inhlobonhlobo yezinye izinhlelo zokusebenza, okuhlanganisa amapayipi kawoyela negesi, izisekelo zesakhiwo kanye namaphrojekthi engqalasizinda.Ukuguquguquka kwayo nokusebenza okuphezulu kuyenza ibe inketho ekhangayo ezimbonini eziningi ezidinga amapayipi ensimbi ekhwalithi ephezulu.
Ukufingqa, i-spiral welded pipe yomugqa wepayipi lomlilo iwumkhiqizo onokusebenza okuphakeme kanye nezinzuzo ezinkulu.Ikhono layo lokukhiqiza amapayipi ensimbi anobubanzi obuhlukahlukene, ubukhulu obunembile, ubuqotho obuhle kakhulu besakhiwo, kanye nezinqubo zokukhiqiza ezonga isikhathi kuyenza ibe inketho eguquguqukayo futhi engabizi kakhulu.Kungakhathaliseki ukuthi amapayipi omlilo noma ezinye izinhlelo zokusebenza, ipayipi elihlanganisiwe elivunguzayo linganikeza ikhwalithi enhle kakhulu nokuthembeka ukuhlangabezana nezidingo zamaphrojekthi nezimboni ezahlukene.
