FlangeIkwabizwa ngokuba yiflange convex disk okanye ipleyiti yeconvex.Ngokuphathelele abo babandakanyeka kumatshini okanye ukufakwa kobunjineli bamaqabane amancinci, kufuneka baqhelane kakhuluiflange.Iyinxalenye yedisk-shaped, isetyenziswa ngokubanzi ngababini.Isetyenziswa ikakhulu phakathi kombhobho kunye nevalve, phakathi kombhobho kunye nombhobho kunye naphakathi kombhobho kunye nezixhobo, njl.Kukho izicelo ezininzi phakathi kwezi zixhobo kunye nemibhobho, ngoko ke iinqwelomoya ezimbini zidityaniswe ngeebholiti, kwaye iindawo ezidibanisayo ezinesiphumo sokutywinwa zibizwa ngokuba.iflange.
Ngokubanzi, kukho imingxuma engqukuva kwiiflangeukudlala indima emiselweyo.Ngokomzekelo, xa usebenzisa kwi-joint yepayipi, ikhonkco lokutywina longezwa phakathi kwezi zibiniiipleyiti zeflange.Kwaye ke uxhulumaniso luqiniswe ngeebholiti.I-flange enoxinzelelo oluhlukeneyo inobunzima obuhlukeneyo kunye neebholiti ezahlukeneyo.Izinto eziphambili ezisetyenziselwa i-flange yintsimbi ye-carbon, insimbi engenasici kunye ne-alloy steel, njl.
Ngenxa yendima yayo ebalulekileyo kunye nokusebenza kakuhle okubanzi,iflangeisetyenziswa kakhulu kwimichiza, i-petrochemical, umlilo kunye namashishini okuhambisa amanzi.
Njengohlobo lwesihlanganisi,iflangeisetyenziswa kakhulu ehlabathini, nto leyo efuna umgangatho omanyeneyo.Umzekelo, kukho ezimbini iinkqubo eziqhelekileyo zeumbhobho flange.
Ziyinkqubo ye-European pipeline flange, ebizwa ngokuba yi-European pipeline flange system emelwe yi-German DIN (kubandakanywa neRashiya), kunye nenkqubo ye-American pipeline flange emelwe yi-American ANSI pipe flange.
Ukongeza, kukho inkqubo ye-JIS yombhobho weflange eJapan kunye nenkqubo yentsimbi yombhobho we-GB eTshayina, kodwa imilinganiselo ephambili isekelwe kwinkqubo yaseYurophu kunye nenkqubo yaseMelika.
Iintlobo zeflange
Ubume beiflangeilula ngokwentelekiso.Iqulunqwe ngamacwecwe e-flange aphezulu nangaphantsi, i-gasket ephakathi kunye neebholiti ezininzi kunye namantongomane.
Ukusuka kwinkcazo yeiflange, sinokwazi ukuba zininzi iintlobo zeiflange, kwaye ukuhlelwa kwayo kufuneka kwahlulwe kwimilinganiselo eyahlukeneyo.Ngokomzekelo, ngokwendlela yokudibanisa, i-flange inokwahlulwa ibeflange ebalulekileyo,flat welding flange,butt welding flange,umkhono okhululekileyokunye tiflange eyotyiweyo, ezikwayi-flange eqhelekileyo.
I-Flange edibeneyo (IF)isetyenziswa ngokubanzi kumbhobho ngoxinzelelo oluphezulu.Luhlobo lwendlela yoqhagamshelwano lweflange, kwaye inentamo ende.Ngokuqhelekileyo iqulunqwe yi-one-time integral casting, kwaye izinto ezisetyenziswayo ngokubanzi ziyi-carbon steel, insimbi engenasici, njl.
I-flat welding flangeIkwabizwa ngokuba yi-tower welding flange.Igqitywe nge-welding xa idibanisa nenqanawa okanye ipayipi.Olu hlobo lweflange ye-welding flat ineempawu zendibano elula kunye nexabiso eliphantsi.Isetyenziswa ikakhulu kumbhobho ngoxinzelelo oluncinci kunye nokungcangcazela.
I-butt welding flangeikwabizwa ngokuba yi-high neck flange.Umahluko omkhulu phakathi kwe-butt welding flange kunye nezinye iiflange kukuba inentamo ephezulu ephumayo.Ubunzima bodonga lwentamo ephakamileyo ephumayo buya kuba ngokuthe ngcembe bufana nobukhulu kunye nobubanzi bodonga lombhobho ukuba lufakwe ngokuphakama, okuya kwandisa amandla e-flange.I-butt welded flange isetyenziswa ikakhulu kwiindawo ezinotshintsho olukhulu lokusingqongileyo, ezifana nobushushu obuphezulu, uxinzelelo oluphezulu kunye nombhobho wobushushu obuphantsi.
I-flange ekhululekileikwabizwa ngokuba yilooper flange.Olu hlobo lwe-flange lusetyenziswa kakhulu kwisinyithi esingenawo intsimbi kunye nemibhobho yensimbi engenasici, kwaye uqhagamshelo lufezekiswa ngokuwelda.Iyakwazi ukujikeleziswa.Kwaye kulula ukulungelelanisa umngxuma webholithi, ngoko ke isetyenziswa ikakhulu kuqhagamshelo lombhobho omkhulu odayamitha kwaye isoloko ifuna ukuqhawuka.Nangona kunjalo, ukunyanzeliswa kwengcinezelo ye-flange ekhululekileyo ayikho phezulu.Ngoko ke ingasetyenziselwa kuphela ukudityaniswa kombhobho woxinzelelo oluphantsi.
Kukho imisonto kwiipleyiti yeflangeyeiflange enemisonto, efuna ukuba umbhobho wangaphakathi uphinde ube nentambo yangaphandle ukuqonda uxhulumaniso.Yiflange engeyiyo i-welding, ngoko ke ineengenelo zofakelo olulula kunye nokuqhaqha xa kuthelekiswa nezinye i-welding flange.Kwindawo yobushushu obuphezulu okanye obuphantsi, i-flange ene-threaded ayifanelekanga ukusetyenziswa, kuba intambo ilula ukuvuza emva kokwandiswa kwe-thermal kunye nokunyuka okubandayo.
