Iiflange zensimbi ezingenasici zisetyenziswa ngokubanzi kuzo zonke iinkalo zobomi ngenxa yokubukeka kwazo okuhle, ubushushu obuphezulu kunye nokumelana noxinzelelo oluphezulu, ukuxhathisa ukubola kunye nezinye iimpawu.Nangona kunjalo, abantu abaninzi baseneengxaki ezininzi ekusebenzeni kweeflange zensimbi ezingenasici.Namhlanje siza kuthetha malunga nendlela yokusombulula iingxaki ezenzeka kwinkqubo yokungaqhubeki iiflange zensimbi ezingenasici.
Ukusetyenzwa kweintsimbi engenasicikufuneka azi kwaye athathele ingqalelo ezinye iingxaki:
1. I-Weld joint defect: i-weld defect ye-stainless steel flange inzima kakhulu.Ukuba i-polish ye-manual mechanical isetyenziselwa ukwenza oko, amanqaku okugaya aya kubangela ukungalingani komhlaba kwaye achaphazele ukubonakala;
2. Ukupolisha okungafaniyo kunye nokugqithisa: emva kokupholisa ngesandla kunye nokupholisa, kunzima ukufezekisa umphumo ofanayo kunye nofanayo wonyango kwiindawo zokusebenza ezinommandla omkhulu, kwaye awukwazi ukufumana indawo efanelekileyo efanayo.Uqhagamshelo lwe-necked flange okanye i-flange joint ibhekiselele ekudibaneni kwe-flange, i-gasket kunye ne-bolt njengeqela lesakhiwo sokutywinwa esidibeneyo.
Iflange yombhobho ibhekisa kwiflange esetyenziselwa ukubhobhoza kwisixhobo sombhobho, kunye neeflange zokungena kunye nokuphuma kwesixhobo xa zisetyenziswa kwisixhobo.Kukho imingxuma kwiiflange, kunye neebholithi zenza ukuba iiflange ezimbini zidityaniswe ngokuqinileyo.I-butt-welding flange luhlobo lofakelo lombhobho, olubhekiselele kwi-flange enentamo kunye nokutshintshwa kombhobho ojikelezileyo kwaye idityaniswe ne-pipe butt welding.Akukho lula ukukhubaza, itywinwe kakuhle kwaye isetyenziswa ngokubanzi.Ilungele imibhobho enoguquko olukhulu kuxinzelelo okanye ubushushu okanye iipayipi ezinobushushu obuphezulu, uxinzelelo oluphezulu kunye nobushushu obuphantsi.Inzuzo kukuba ixabiso lincinci, kwaye uxinzelelo lwegama aludluli i-2.5MPa;
Ikwasetyenziswa kwimibhobho ehambisa iindaba ezibizayo, ezinokutsha kunye neziqhumayo, ngoxinzelelo lwegama malunga ne-PN16MPa.Kukwakho nokungalunganga kwayo, njengeendleko zeeyure zokusebenza kunye nezinto ezincedisayo;
3. Imikrwelo kunzima ukuyisusa: i-pickling jikelele kunye ne-passivation, i-carrosion yekhemikhali okanye i-electrochemical corrosion iya kwenzeka kwaye i-rust iya kwenzeka phambi kwemithombo yeendaba ezonakalisayo (izinto ezithatha isigqibo), kunye ne-carbon steel, i-spatter kunye nezinye izinto ezingcolileyo ezinamathele kumphezulu wensimbi engenasici. ngenxa yemikrwelo kunye ne-welding spatter ayinakususwa;
Ngoko indlela yokusombulula ingxaki yeintsimbi engenasiciukuqhubekeka?
1. Khetha ukuvala, uze ufake inkqubo elandelayo.Izixhobo zokusebenza ezahlukeneyo kwi-stainless steel flange processing zingena kwinkqubo ehambelanayo ngokweemfuno zokucubungula;
2. Xa ugoba, isixhobo kunye ne-groove esetyenziselwa ukugoba iya kugqitywa ngokuhambelana nobukhulu bomzobo kunye nobukhulu bensimbi engenasici ye-304 ipayipi yensimbi engenamthungo.Isitshixo ekukhethweni kwesikhunta esiphezulu kukuphepha ukuguqulwa okubangelwa ukungqubuzana phakathi kwe-flange kunye nesixhobo (inkcazo: inxalenye ebalulekileyo yesifaniso) (imizekelo eyahlukeneyo ye-mold ephezulu ingasetyenziswa kwimveliso efanayo).Ukukhethwa kwe-mold ephantsi kunqunywe ngokuhambelana nobukhulu beplate.Xa kudityaniswa impompo kunye nevalve yomenzi weflange kunye nombhobho, iindawo zezi zixhobo zenziwe kwakhona kwiimilo zeflange ezihambelanayo, ezaziwa ngokuba luqhagamshelo lweflange.
3. Ukuze weld ngokuqinileyo, ngenqindi iqhuma kwi workpiece ukuba welded, nto leyo enokwenza udibaniso iqhuma kunye ipleyiti flat ngokulinganayo phambi amandla-on welding ukuqinisekisa ukuhambelana ukufudumeza kwindawo nganye, kwaye kwakhona ukumisela indawo welding. , ekufuneka idityaniswe.Lungisa ixesha lokucinezela kwangaphambili, ixesha lokubamba uxinzelelo, ixesha lokuyigcina, kunye nexesha lokuphumla ukuqinisekisa ukuba i-workpiece inokudityaniswa idityaniswe ngokuqinileyo.
