Yintoni iFlange kwaye zeziphi iintlobo zeFlange?

inyani, igama likaiflengiyinguqulelo yolwimi. Yaqala ukubekwa phambili yindoda yaseNgilani egama lingu-Elchert ngo-1809. Kwangaxeshanye, wacebisa indlela yokubhalaiflengiNangona kunjalo, ayizange isetyenziswe kakhulu emva kwexesha elide. Kude kube sekuqaleni kwenkulungwane yama-20,iflengiyayisetyenziswa kakhulu kwizixhobo ezahlukeneyo zoomatshini kunye noqhagamshelo lwemibhobho.

Yintoni iflange?
Iflengiikwaziwa ngokuba yidiski ye-flange convex okanye ipleyiti ye-convex. Ngokuphathelele abo babandakanyeka ekufakeni oomashini okanye ubunjineli bamaqabane amancinci, kufuneka baqhelene kakhulu ne-iflengiZiinxalenye ezimile okwediski, ezisetyenziswa rhoqo ngababini. Zisetyenziswa kakhulu phakathi kombhobho kunye nevalvu, phakathi kombhobho kunye nombhobho kunye naphakathi kombhobho kunye nezixhobo, njl. Ziinxalenye ezidibanisa ngesiphumo sokutywina. Kukho usetyenziso oluninzi phakathi kwezi zixhobo kunye nemibhobho, ngoko ke ezi planes zimbini ziqhagamshelwe ngeebholthi, kwaye iindawo ezidibanisayo ezinesiphumo sokutywina zibizwa ngokubaiflengi.

Ngokubanzi, kukho imingxunya engqukuvaiflengiukudlala indima esisigxina. Umzekelo, xa usebenzisa kwindawo yokudibanisa umbhobho, kongezwa iringi yokutywina phakathi kwezi zimbiniiipleyiti zeflangeEmva koko uqhagamshelo luqiniswa ngeebholiti. Iflange enoxinzelelo olwahlukileyo inobukhulu obahlukeneyo kunye neebholiti ezahlukeneyo. Izinto eziphambili ezisetyenziselwa iflange yintsimbi yekhabhoni, intsimbi engatyiwayo kunye nentsimbi ye-alloy, njl.njl.

Ngenxa yendima yayo ebalulekileyo kunye nokusebenza kakuhle okubanzi,iflengiisetyenziswa kakhulu kwimizi-mveliso yeekhemikhali, iikhemikhali zepetroli, umlilo kunye nemijelo yamanzi amdaka.

Njengohlobo loqhagamshelwano,iflengiisetyenziswa kakhulu kwihlabathi liphela, nto leyo efuna umgangatho omnye. Umzekelo, kukho iinkqubo ezimbini ezisemgangathweniiflengi yombhobho.

Ziyinkqubo yeflange yemibhobho yaseYurophu, oko kukuthi inkqubo yeflange yemibhobho yaseYurophu emelwe yiGerman DIN (kuquka neRussia), kunye nenkqubo yeflange yemibhobho yaseMelika emelwe yiflange yemibhobho yaseMelika yeANSI.

Ukongeza, kukho inkqubo ye-JIS pipeline flange system eJapan kunye ne-steel pipe flange system GB eTshayina, kodwa ubukhulu obuphambili busekelwe kwinkqubo yaseYurophu kunye nenkqubo yaseMelika.

Iintlobo zeflange
Ulwakhiwo lweiflengiilula kakhulu. Yenziwe ngeepleyiti zeflange eziphezulu nezisezantsi, i-gasket ephakathi kunye neebholiti kunye neenati ezininzi.

Ukusuka kwinkcazo yeiflengi, singazi ukuba kukho iintlobo ezininziiflengi, kwaye udidi lwayo kufuneka lwahlulwe kwiimilinganiselo ezahlukeneyo. Umzekelo, ngokwendlela yoqhagamshelo, iflange ingahlulwahlulwa ibei-flange edibeneyo,iflegi yokuwelda ethe tyaba,i-flange yokuwelda yempundu,iflengi yemikhono ekhululekileyokunye no-tiflengi enemisonto, ezikwayiflange eqhelekileyo.

I-flange edibeneyo (IF)isetyenziswa kakhulu kwipayipi enoxinzelelo oluphezulu. Luhlobo lwendlela yoqhagamshelo lweflange, kwaye lunentamo ende. Idla ngokwenziwa nge-once-time integral casting, kwaye izinto ezisetyenziswayo ngokubanzi yi-carbon steel, i-stainless steel, njl.

I-flange yokuwelda ethe tyabaIkwaziwa ngokuba yi-tower welding flange. Igqitywa ngokuhlanganisa xa iqhagamshelwa kwisitya okanye kwipayipi. Olu hlobo lweflange yokuhlanganisa ethe tyaba luneempawu zokuba lula ukuyihlanganisa kwaye lunexabiso eliphantsi. Isetyenziswa kakhulu kwipayipi enoxinzelelo oluncinci kunye nokungcangcazela okuncinci.

I-flange yokuwelda ye-Buttikwaziwa ngokuba yiflange yentamo ephezulu. Umahluko omkhulu phakathi kweflange ye-butt welding kunye nezinye iiflange kukuba inentamo ephezulu ephumayo. Ubukhulu bodonga lwentamo ephezulu ephumayo buya kufana kancinci nobukhulu kunye nobubanzi bodonga lombhobho oluza kuxhonywa ngokuphakama, okuya kwandisa amandla eflange. Iflange ye-butt welded isetyenziswa kakhulu kwiindawo ezinotshintsho olukhulu kwindalo, njengobushushu obuphezulu, uxinzelelo oluphezulu kunye nombhobho wobushushu obuphantsi.

I-flange ekhululekileyoikwaziwa ngokuba yi-looper flange. Olu hlobo lweflange lusetyenziswa kakhulu kwiipayipi zesinyithi ezingenayo i-ferrous kunye ne-stainless steel, kwaye uqhagamshelo lwenziwa ngokuwelda. Ingajikeleziswa. Kwaye kulula ukulungelelanisa umngxuma we-bolt, ngoko ke isetyenziswa kakhulu ekuqhagamshelweni kombhobho omkhulu kwaye idla ngokufuna ukuqhaqhwa. Nangona kunjalo, ukumelana noxinzelelo lweflange ekhululekileyo akuphezulu. Ngoko ke ingasetyenziselwa kuphela ukuqhagamshelwa kombhobho ophantsi koxinzelelo.

Kukho imisonto kwiipleyiti yeflangeyeiflengi eneentambo, nto leyo efuna ukuba umbhobho wangaphakathi ube nomsonto wangaphandle ukuze ukwazi ukunxibelelana. Yiflange engawelisiyo, ngoko ke ineengenelo zokufakelwa nokuqhaqhwa okulula xa kuthelekiswa nezinye iiflange zokuwelda. Kwimeko yobushushu obuphezulu okanye obuphantsi, iflange eneentambo ayifanelekanga ukusetyenziswa, kuba umsonto kulula ukuwuvuza emva kokwandiswa kobushushu kunye nokuxinana okubandayo.
