Ipayipi ELISHISELEKILE LESIMBALI ERW ELISHISELEKILE I-SAW ELISHISELELWE IPHAYIBHI LESIBILI
Incazelo
Ipayipi elishiselwe ngezinqe lakhiwa ngokuphakela ipuleti lensimbi elishisayo ngokusebenzisa izimo ezizoligoqa libe yisimo esiyindilinga esingenalutho.Ukucindezela iziphetho ezimbili zepuleti ndawonye kuzokhiqiza inhlanganisela ehlanganisiwe noma umthungo.Umfanekiso 2.2 ubonisa ipuleti lensimbi njengoba liqala inqubo yokwenza ipayipi elishiselwe ngezinqe
Okungajwayelekile kakhulu kulezi zindlela ezintathu ipayipi elishiselwe ku-spiral.Ipayipi eli-spiral-welded lakhiwa ngamapheshana ensimbi asontekile abe umumo ozungezayo, ofana negxolo lomgundi, bese liyashisela lapho imiphetho ihlangana khona ukuze kwakheke umthungo.Lolu hlobo lwepayipi luvinjelwe ezinhlelweni zamapayipi zisebenzisa izingcindezi eziphansi ngenxa yezindonga zalo ezincane.Umfanekiso 2.3 ukhombisa ipayipi eli-spiral-welded njengoba livela ngaphambi kokushisela.
Ngayinye yezindlela ezintathu zokukhiqiza ipayipi inezinzuzo zayo kanye nokubi.Ipayipi elishiselwe ngezinqe, ngokwesibonelo, lakhiwa ngepuleti eligoqiwe elinogqinsi olufana nolwengeziwe futhi lingahlolwa ukuthi alinasici yini ngaphambi kokwakheka nokushisela.Le ndlela yokukhiqiza iwusizo ikakhulukazi lapho kudingeka izindonga ezincane nobude obude.Ngenxa yomthungo oshiselwe, nokho, kuhlale kunethuba lokulimala okuphunyuka ekuhlolweni okuningi kokulawulwa kwekhwalithi okwenziwa phakathi nenqubo yokukhiqiza.
Ngenxa yalokho, i-American National Standards Institute (ANSI) yakha iziqondiso eziqinile zokwenziwa kwamapayipi.I-Pressure Piping Code B31 yabhalelwa ukulawula ukwenziwa kwepayipi.Ikakhulukazi, i-code B31.1.0 inika amandla angu-85% epayipi eligoqiwe, ama-60% amapayipi ashiselwe ku-spiral, kanye nokusebenza kahle kuka-100% kumapayipi angenamthungo.
Ngokuvamile, ukuqina kwezindonga ezibanzi kukhiqizwa ngendlela engenamthungo.Kodwa-ke, ekusetshenzisweni okuningi kokucindezela okuphansi kwepayipi, indlela eqhubekayo ehlanganisiwe iyona eyonga kakhulu.Ipayipi elingenamthungo likhiqizwa ngobude obungahleliwe obubodwa nakabili.Ubude obubodwa bokungahleliwe buyahluka ukusuka ku-16′-0″kuya ku-20′-0″.Amapayipi 2″ nangaphansi atholakala ngobude obuphindwe kabili obungahleliwe obusuka ku-35′-0″ ukuya ku-40′-0″.
