Uyazi ukuthi yini i-flange egoqiwe ebandayo?

I-Cold rolled flange iwuhlobo lwe-flange evame ukusetshenziswa ekuxhumekeni kwamapayipi, aziwa nangokuthi i-flange egoqiwe ebandayo. Uma kuqhathaniswa nama-flange akhiwe, izindleko zayo zokukhiqiza ziphansi, kodwa amandla ayo nokusebenza kokuvala akukho ngaphansi kwama-flange akhiwe. Ama-cold rolled flanges angasetshenziswa ezinhlotsheni ezihlukahlukene zama-flange, kuhlanganiseamapuleti flange, ama-flange we-butt welding, ama-flanges anemicu, njll

Ama-cold rolled flange afanele izinhlobo ezahlukene zokuxhunywa kwamapayipi, okuhlanganisa i-petrochemical, ukwakhiwa kwemikhumbi, ukwelashwa kwamanzi, ukushisa nokukhipha umoya, ukuhlinzekwa kwamanzi emadolobheni nezinye izinkambu. Izinzuzo zokukhiqiza i-flange egoqwe abandayo yinqubo yayo elula, izindleko eziphansi, futhi isebenza ezinhlotsheni ezihlukahlukene zezinto kanye namapayipi ogqinsi, ngakho-ke isetshenziswe kabanzi.

Inqubo yokukhiqiza i-flange ebandayo egoqiwe iwukugoba ipuleti lensimbi libe yindingilizi bese ushisela amaphethelo amabili ndawonye ukuze kwakheke indandatho. Le ndlela yokushisela ibizwa ngokuthi i-girth welding, futhi ingaba i-manual welding noma i-automatic welding. Ama-flange agoqwe abandayo angenziwa ngosayizi ojwayelekile, futhi ama-flange osayizi ongajwayelekile nawo angenziwa ngokuya ngezidingo zamakhasimende.

Ubuchwepheshe bokucubungula bokuphonsa i-coiling flange ebandayo: faka insimbi eluhlaza ekhethiwe esithandweni somlilo esiphakathi imvamisa yokuncibilikisa, ukuze izinga lokushisa lensimbi encibilikisiwe lifinyelele ku-1600-1700 ℃; Isikhunta sensimbi sishiswe ngaphambili sibe ngu-800-900 ℃ ukuze silondoloze izinga lokushisa elingaguquki; Qala i-centrifuge bese ujova insimbi encibilikisiwe esikhunjini sensimbi esandulelwe ngaphambili; Ukusakaza kupholiswe ngokwemvelo ku-800-900 ℃ imizuzu engu-1-10; Pholisa ngamanzi ukuze uvale izinga lokushisa legumbi, susa isikhunta bese ukhipha ukubunjwa.

Izinzuzo zama-flanges abandayo zihlanganisa izindleko eziphansi zokukhiqiza, ukukhiqiza nokufaka kalula, ukumelana nokugqwala okuhle, nesisindo esincane. Kodwa-ke, uma kuqhathaniswa nama-flange omgunyathi, amandla nokusebenza kokuvala kwama-flange abandayo kungase kube kubi kakhulu. Ngakho-ke, kwezinye izinhlelo zokusebenza ezinomfutho ophezulu noma izinga lokushisa eliphezulu, kusadingeka ukusebenzisa ama-flange akhiwe noma okunye ukuxhumeka kwamapayipi okuqiniswe kakhulu.
