Iintlobo eziphambili zee-flange gaskets
Iigaskets ezingezizo ezesinyithi
Izinto eziqhelekileyo: irabha, i-polytetrafluoroethylene (PTFE), ifayibha engeyiyo i-asbestos (i-asbestos yerabha).
Iindlela eziphambili zokusetyenziswa kunye neempawu:
Ii-gaskets zerabha ze-asbestos ezazisetyenziswa kakhulu emanzini, emoyeni, ngomphunga, nge-asidi nakwi-alkali media, zazikhe zathandwa kakhulu.
Kwiimeko ezinganyangekiyo ngumhlwa, ii-gasket ze-PTFE zinozinzo oluhle kakhulu lweekhemikhali.
Iigaskets zesinyithi
Izinto eziqhelekileyo: Ibhendi yesinyithi + igrafiti/i-asbestos/ibhendi egcwele i-PTFE (uhlobo lwenxeba), umbindi ongengowesinyithi ogqunywe ngesinyithi, i-gasket edityanisiweyo yegrafiti eguquguqukayo.
Iindlela eziphambili zokusetyenziswa kunye neempawu:
Ukudibanisa amandla esinyithi kunye nokuthamba kwesinyithi esingesisinyithi kwiimeko zokusebenza ezishushu kakhulu, ezixinezelekileyo neziguquguqukayo. Phakathi kwazo, ii-gaskets zesinyithi ezilukhetho oluphambili kwi-petrochemical, chemical kunye nezinye izimboni.
Kwiimfuno eziqinileyo zokutywina, ezinje ngee-gaskets zentsimbi ezirhangqiweyo/ezinamaza, zisetyenziswa kwimibhobho okanye kwimikhumbi yoxinzelelo enoxinzelelo oluphezulu kunye nobushushu.
Iigasket zesinyithi
Izinto eziqhelekileyo: intsimbi ethambileyo, intsimbi engatyiwayo, ubhedu, i-Monel alloy.
Izicelo eziphambili kunye neempawu:
Iimeko ezigqithisileyo: zisetyenziswa kwiindawo ezinobushushu obuphezulu, ezinoxinzelelo oluphezulu kunye nezonakalisayo kakhulu.
Zibonelela ngokusebenza kakuhle kokutywina kodwa zinemfuneko ephezulu kakhulu yokuchaneka kokutywina komphezulu wokutywina kunye nokufakelwa kweflange, kwaye zibiza kakhulu.
Xa ukhetha ii-gasket, kufuneka kuqwalaselwe izinto ezininzi ngokupheleleyo. Eyona nto iphambili ikumanqaku amane aphambili: “iphakathi, uxinzelelo, ubushushu, kunye neflange".
Iipropati eziphakathi: Kwizinto ezibangela ukugqwala (ezifana nee-asidi kunye ne-alkalis), izinto ze-gasket kufuneka zingagqwali.
Uxinzelelo olusebenzayo kunye nobushushu: Kwiimeko zobushushu obuphezulu kunye noxinzelelo oluphezulu, kufuneka kukhethwe ii-gaskets zesinyithi okanye zesinyithi ezimelana nobushushu kunye noxinzelelo.
Uhlobo lomphezulu wokutywina weFlange: Iindawo ezahlukeneyo zeflange (ezifana neRF yobuso obuphakanyisiweyo, i-MFM yobuso bobudoda nobobufazi, i-tongue kunye ne-groove face TG) mazihambelane neentlobo ezithile ze-gasket.
Ezinye izinto: Ukungcangcazela, ukuguquguquka rhoqo kobushushu kunye noxinzelelo, imfuneko yokuqhaqhwa rhoqo, kunye nohlahlo lwabiwo-mali lweendleko nazo maziqwalaselwe.
Kuko konke,
Kwi-common media enoxinzelelo oluphantsi (amanzi, umoya, umphunga onoxinzelelo oluphantsi): Ii-non-metallic gaskets, ezifana nerabha okanye ii-PTFE gaskets, ziyathandwa ngenxa yokuba zibiza kakhulu.
Kwiimeko zokusebenza ezixineneyo neziphezulu, ubushushu obuphezulu okanye iimeko ezinzima (iipayipi kwimizi-mveliso yepetroleum, iikhemikhali kunye namandla): Iigaskets ze-semi-metallic, ngakumbi iigaskets zesinyithi, zezona zikhethwayo nezithembekileyo.
Kwiimeko zobushushu obuphezulu kakhulu kunye noxinzelelo okanye iimeko ezirhabaxa kakhulu: Iigasket zesinyithi (ezifana neegaskets ezirhabaxa okanye ezijikelezayo) kufuneka ziqwalaselwe, kodwa kubalulekile ukuqinisekisa ukuhambelana okufanelekileyo kweflange kunye nokufakelwa ngokuchanekileyo.
