Flanges Jikelele

I-flange yindlela yokudibanisa imibhobho, iivalve, iimpompo kunye nezinye izixhobo zokwenza inkqubo yokubhobhoza. Ikwabonelela ngokufikelela lula ukucoca, ukuhlola okanye ukuguqulwa. Iiflange zidla ngokudityaniswa okanye zikrwelwe. Amalungu ajikelezileyo enziwa ngokudibanisa iiflange ezimbini kunye ne-gasket phakathi kwazo ukunika itywina.

Izixhobo zeFlanges

Iiflange zemibhobho zenziwa kuzo zonke izinto ezahlukeneyo ezifana nentsimbi engatyiwa, intsimbi, ialuminiyam, ubhedu, ubhedu, iplastiki njl.

Ukongezelela, iiflegi, ezifana nokufakelwa kunye nemibhobho, ngeenjongo ezithile ngamanye amaxesha ngaphakathi ngaphakathi kuxhotyiswe ngemigangatho yezinto ezisemgangathweni ohluke ngokupheleleyo njengama-flanges ngokwawo, "ayi-lined flanges".

Izinto eziphathekayo ze-flange, zibekwe ngokusisiseko ngexesha lokukhethwa kombhobho, kwiimeko ezininzi, i-flange yinto efanayo kunye nombhobho.

Zonke iiflange, ezixoxwe kule webhusayithi ziwela phantsi kwemigangatho ye-ASME en ASTM, ngaphandle kokuba kuboniswe ngenye indlela. I-ASME B16.5 ichaza imilinganiselo, ukunyamezelwa kwe-dimensional njl. kunye ne-ASTM iimpawu zemathiriyeli ezahlukeneyo.

Imilinganiselo yeeFlanges

I-flange nganye ye-ASME B16.5 inenani lemilinganiselo eqhelekileyo. Ukuba idrafti eJapan okanye umlungiseleli womsebenzi eCanada okanye i-pipefitter e-Australia ithetha nge-Welding Neck flange NPS 6, i-Class 150, iShedyuli ye-40 ASME B16.5, emva koko iya ngaphaya kwe-flange ekulo mfanekiso ungezantsi ubonisiwe. .

Ukuba i-flange iyalwe, umthengisi ufuna ukwazi umgangatho wezinto eziphathekayo. Umzekelo i-ASTM A105 yintsimbi ye-carbon steel flange, ngelixa i-A182 yintsimbi yensimbi engenasici.

Ke, ngokulandelelana okuchanekileyo kumthengisi kufuneka kucaciswe imigangatho emibini:

Uqhagamshelo lweFlange eBolted

Uxhulumaniso lwe-flange oludibeneyo ludibaniso oluyinkimbinkimbi yezinto ezininzi (i-Flange, i-Bolts, i-Gaskets, iNkqubo, i-Temperature, i-Pressure, i-Medium). Zonke ezi zinto zahlukeneyo zinxibelelene kwaye zixhomekeke omnye komnye ukuphumeza iziphumo eziyimpumelelo.
Ukuthembeka komdibaniso odibeneyo kuxhomekeke kakhulu kulawulo olunobuchule lwenkqubo yokwenziwa kwendibaniselwano.

Ukucaphula kwincwadi kaJohn H. Bickford, "Intshayelelo yoYilo kunye nokuziphatha kwaMajoyinti aBolted":
Ukuba onke amandla okubamba okubalulekileyo abamba ikhonkco kunye - kwaye ngaphandle kwayo bekungekho kudibanisa - ayidalwanga ngumyili odibeneyo, okanye ngamacandelo aphezulu. Idalwe ngumkhandi kwindawo yomsebenzi, esebenzisa izixhobo, iinkqubo, kunye neemeko zokusebenza esimnike zona… Kwaye ngakumbi: Umyili wokugqibela, obalulekileyo wamandla ngumkhandi, kwaye ixesha lokuyilwa kukwixesha lokudibanisa. Ngoko ke kubaluleke kakhulu ukuba siyiqonde le nkqubo.

Ishishini liye laqaphela ubume obubalulekileyo bofakelo kunye nokudibanisa iminyaka emininzi.
EYurophu, ugxininiso luye lwaqinisekisa ukuba ukwenziwa ngokubambisana kwenziwa ngabachwephesha abaqeqeshiweyo nabaqinisekisiweyo kwaye oku kuye kwakhokelela ekupapashweni komgangatho woBuchwephesha baseYurophu: TS EN 1591 Icandelo le-4 elinesihloko esithi "Flanges kunye namalungu abo. Uyilo imithetho gasketed uqhagamshelo setyhula flange. Isiqinisekiso sobuchule babasebenzi ekudibaneni kwamalungu adityanisiweyo afakwe kwisixhobo esiphantsi koMyalelo weSixhobo soxinzelelo (PED)”.

Umgangatho ubonelela ngendlela yoqeqesho kunye novavanyo lwabachwephesha ababandakanyekayo ekwenziweni nasekuqhekezweni kwamalungu e-flange kwaye kunokubonwa njengokufana noqeqesho olufunekayo kubashiseli ababandakanyekayo kumsebenzi wenqanawa yoxinzelelo. Upapasho lwayo lubonisa ukubaluleka okubekwe kulawulo olufanelekileyo lwenkqubo yokwenziwa ngokubambisana ekuqinisekiseni ukusebenza okungavuziyo kwiflange.

Igasket sesinye sezizathu ezininzi zokudityaniswa kweflange ebolithiweyo kunokuvuza.
Naxa onke amacandelo adityanisiweyo adityanisiweyo adityanisiweyo asebenza ngokuhambelana ngokugqibeleleyo, eyona nto ibaluleke kakhulu ekhokelela kwimpumelelo okanye ukusilela kolu qhagamshelo lweflange ebolithiweyo iya kunikwa ingqwalasela kufakelo olufanelekileyo kunye neenkqubo zokudityaniswa ngumntu ofaka igasket. . Ukuba yenziwe ngokufanelekileyo, indibano iya kuhlala ingavuzi kubomi obulindelekileyo.
