Ukujikeleza okujikelezayonon-metallic ukwandiswa jointkunye noluxande non-metallic ulusu luhlobo lwesikhumba ilaphu non-metal. Xa kuthelekiswa ne-hemming eqhelekileyo yokwandiswa kwesikhumba esihlangeneyo, ngexesha lokuvelisa, i-workshop kufuneka yenze iikona ezijikelezayo okanye zesikwere ukuze kube lula ukufakwa ngokwemizobo. Inkqubo yokuvelisa inzima ngakumbi. Ulusu olungelulo lwentsimbi luhlobo olutsha lwe-high-tech thermal insulation material eyenziwe ngelaphu lefiber yeglasi kunye ne-silica gel egqunywe ngelaphu lefiber yeglasi kunye nelinye ilaphu elingatshiyo kunye nobushushu obuphezulu. Xa kuthelekiswa nezixhobo zetsimbi, ukusebenza okubanzi kwezinto ezingezizo ezentsimbi ezifana nokumelana nobushushu obuphezulu, ukuxhathisa kweasidi kunye nealkali kunye nokuzinza kweekhemikhali kuye kwadlula kakhulu kwizinto zetsimbi. Ukungonakali kwezikhumba zelaphu eziguquguqukayo ezingezizo ezentsimbi kukuba azinakusetyenziswa kwiindawo ezinoxinzelelo oluphezulu. Ngokuqhelekileyo, kwiindawo ezingaphezulu kwe-0.5mpa, kuyimfuneko ukuqwalasela ukusebenzisa i-metal expansion joints okanye i-non-metallic joints expansion joints.
Njani inani lamalungu angeyontsimbi yokwandiswa?
1. Iibhotshi ze-flange kufuneka ziqiniswe ngokuthe ngcembe kwaye ngokufanayo, kwaye ukuqina kweebhotshi kufuneka kuhambelane ngokusemandleni. Kwimeko yeemeko ezinzima, i-spring washer ebuthakathaka inokuthi ifakwe ngaphezu kwe-washer flat ukukhusela i-nut ukuba ingakhululeki.
2. I-gasket ye-asbestos yerabha ehambelanayo kufuneka isetyenziswe kuqala ngokuhambelana nokushisa okusebenzayo phakathi kwejoyinti yokwandisa kunye neflange ye-welding flat.
3. Ngethuba lovavanyo lwelingo, isikrufu somda we-joint yokwandiswa kufuneka silungiswe ngokufanelekileyo ukulungiselela ukwandiswa okanye ukunyanzeliswa kwemveliso.
4. Xa umbhobho odityanisiweyo uqhagamshelwe, isikrufu somda kufuneka sikhululwe ngokufanelekileyo ukuze kuthintelwe ipleyiti elinganiselweyo yejoyinti yokwandiswa ukuba ingagotywa okanye ikhubazeke imveliso.
5. Ngethuba lokusebenza kwe-welding, isetyenziswe njengesigqubuthelo sokugubungela ubuso berubha (indwangu) ukukhusela i-welding slag ekulimazeni imveliso.
Sikwanjaloimibhobho yomoya eguquguqukayo, imibhobho yomoya egqunyiweyo egqunyiweyo!
