Kev ua ntawm stainless hlau flange yuav tsum nkag siab thiab xyuam xim rau cov teeb meem hauv qab no:
1, weld defects: stainless hlau flange weld defects yog qhov hnyav dua, yog tias nws yog siv phau ntawv kho tshuab sib tsoo txoj kev los ua, ces qhov sib tsoo cov qhab nia, ua rau qhov tsis sib xws, yuav cuam tshuam rau cov tsos;
2, polishing thiab polishing passivation tsis zoo ib yam: kev kho mob passivation tom qab phau ntawv sib tsoo thiab polishing, rau thaj chaw ua haujlwm loj, nws yog qhov nyuaj rau kev ua tiav cov txiaj ntsig kev kho mob, tsis tuaj yeem tau txais qhov zoo tshaj plaws uniform nto. Nws kuj muaj qhov tsis zoo ntawm tus txiv neej-teev cov nqi, cov nqi accessories yog siab dua;
3, khawb yog ib qho nyuaj rau tshem tawm: zuag qhia tag nrho pickling passivation, nyob rau hauv lub xub ntiag ntawm corrosive nruab nrab yuav tshwm sim tshuaj corrosion los yog electrochemical corrosion thiab xeb, kuj tsis tuaj yeem tshem tawm vim khawb, vuam txaws thiab ua raws li qhov chaw ntawm stainless hlau carbon steel, txaws. thiab lwm yam impurities;

Yog li yuav daws qhov teeb meem ntawm stainless hlau flange ua li cas?
1, xaiv blanking, tom qab ua tiav, rau hauv cov txheej txheem tom ntej, sib txawv stainless hlau workpiece raws li cov txheej txheem ua tiav rau hauv cov txheej txheem sib xws;
2, khoov rau thawj zaug ntawm qhov loj, raws li cov duab kos stainless 304 seamless steel tube khoom thickness los txiav txim siab khoov nrog riam thiab riam trough, zam cov khoom nrog txiav cov cuab yeej sib tsoo ua rau deformation yog tus yuam sij rau kev xaiv hom (hauv tib cov khoom, tej zaum yuav siv cov qauv sib txawv ntawm lub Upper tuag), thiab kev xaiv ntawm qis tuag txiav txim siab raws li lub thickness ntawm lub plank.
3, nyob rau hauv thiaj li yuav welding yog ruaj khov, nyob rau hauv lub vuam workpiece convex point, yuav ua rau lub pob nyob rau hauv pem hauv ntej ntawm lub welding hluav taws xob thiab phaj sib cuag, los xyuas kom meej qhov zoo ib yam ntawm txhua qhov taw tes rau cua sov, vuam txoj hauj lwm yuav txiav txim siab tib yam. Lub sij hawm, qhov xav tau ntawm vuam, kho lub sij hawm ua ntej, lub sij hawm tuav, tuav lub sij hawm thiab lub sij hawm so, xyuas kom cov workpiece tuaj yeem pom vuam yog ruaj.
