Kungani ipayipi elivunguzayo lilungile epayipini lokuthutha uwoyela negesi?

Emkhakheni wokuthutha uwoyela negesi, ipayipi elivunguzayo libonisa izinzuzo eziyingqayizivele ngaphezuluIpayipi le-LSAW, okubangelwa ikakhulukazi izici zobuchwepheshe ezilethwa umklamo wayo okhethekile kanye nenqubo yokukhiqiza.
Okokuqala, indlela yokwenza ipayipi elivunguzayo yenza kube nokwenzeka ukusebenzisa umucu wensimbi omncane ukuze ukhiqizeipayipi elikhulu lensimbi eliwububanzi, okubaluleke kakhulu kumaphrojekthi wokuthutha uwoyela negesi adinga amapayipi amakhulu obubanzi. Uma kuqhathaniswa namapayipi e-LSAW, amapayipi asongekile adinga impahla eluhlaza encane yobubanzi obufanayo, ngaleyo ndlela ehlise izindleko zokukhiqiza. Ngaphezu kwalokho, ipayipi elivunguzayo lihlanganiswe ne-helical welds, elingahlakaza ukucindezeleka ngokulinganayo uma lingaphansi kwamandla, ukuthuthukisa amandla okucindezela kanye nokuzinza okuphelele kwepayipi.

Okwesibili,ipayipi elivunguzayoivamise ukushiselwa ngobuchwepheshe bokushisela be-arc obungaphansi kwamanzi obuzenzakalelayo, obunobuhle bekhwalithi ephezulu yomthungo, isivinini sokushisela okusheshayo nokusebenza kahle kokukhiqiza okuphezulu. I-arc welding engaphansi kwamanzi ingaqinisekisa ukuminyana namandla omthungo we-weld futhi inciphise ingozi yokuvuza okubangelwa ukukhubazeka kokushisela. Ngesikhathi esifanayo, i-weld seam yepayipi elivunguzayo isatshalaliswa ngendlela ezungezayo, yenza i-engeli ethile nge-axis yepayipi, futhi lokhu kuhlelwa kwenza i-weld seam imelane kangcono nokunwetshwa kokuqhekeka lapho ipayipi licindezelwa, futhi kuthuthukisa ukusebenza kwepayipi okulwa nokukhathala.

Ngaphezu kwalokho,isaha ipayipiingabhekana nokutholwa kwamaphutha e-ultrasonic ku-inthanethi nokunye ukuhlola okungabhubhisi phakathi nenqubo yokukhiqiza ukuze kuqinisekiswe ukuthi ikhwalithi yepayipi ngalinye ihlangabezana nezindinganiso. Izinyathelo ezinjalo zokulawula ikhwalithi eziqinile zenza ipayipi elivunguzayo liphephe futhi lithembeke kakhulu ezindaweni ezinobungozi kakhulu njengokuthuthwa kukawoyela negesi.

Okokugcina, i-spiral pipe nayo inokugqwala okuhle nokumelana nokugqoka. Enqubweni yokuthutha uwoyela negesi, ipayipi idinga ukumelana nokugqwala kanye nomphumela wokugaya wemidiya ehlukahlukene. Ipayipi elivunguzayo lingathuthukisa ngokuphawulekayo ukumelana nokugqwala kwalo futhi lelule impilo yalo yesevisi ngokwelashwa okungaphezulu okufana ne-anti-corrosion coating noma i-hot-dip galvanizing nezinye izinyathelo. Ngesikhathi esifanayo, izici zesakhiwo sepayipi elivunguzayo futhi zenza kube nokumelana okuthile kokugqoka, kungamelana nezinhlayiya eziqinile phakathi odongeni lwangaphakathi lokukhuhla ipayipi.

Kafushane, izinzuzo zepayipi elivunguzayo epayipini lokuthutha likawoyela negesi libonakala ngokuyinhloko kumthamo walo omkhulu wokukhiqiza ububanzi, umthamo wengcindezi ephezulu, ikhwalithi enhle kakhulu yokushisela, izinyathelo eziqinile zokulawula ikhwalithi kanye nokugqwala okuhle nokungagugi. Lezi zici zobuchwepheshe zenza ipayipi elivunguzayo libe enye yezinto ezibalulekile futhi ezibalulekile emkhakheni wokuthuthwa kukawoyela negesi.
