Stainless hlau flanges yog dav siv nyob rau hauv tag nrho cov mus taug kev ntawm lub neej vim hais tias ntawm lawv zoo nkauj tsos, siab kub thiab siab kub kuj, corrosion kuj thiab lwm yam ntxwv. Txawm li cas los xij, ntau tus neeg tseem muaj ntau yam teeb meem hauv kev ua cov hlau stainless flanges. Niaj hnub no peb yuav tham txog yuav ua li cas los daws cov teeb meem uas tshwm sim nyob rau hauv tus txheej txheem ntawm tsis ua stainless hlau flanges.
Kev ua ntawmstainless hlau flangeyuav tsum paub thiab xyuam xim rau qee qhov teeb meem:
1. Weld joint defect: weld defect ntawm stainless hlau flange yog qhov loj heev. Yog tias phau ntawv siv tshuab polishing yog siv los ua rau nws, qhov sib tsoo cov cim yuav ua rau tsis sib xws thiab cuam tshuam rau cov tsos;
2. Tsis sib luag polishing thiab passivation: tom qab phau ntawv polishing thiab polishing, nws yog ib qho nyuaj rau kev ua kom zoo ib yam thiab zoo tib yam kev kho mob nyhuv rau workpieces nrog loj cheeb tsam, thiab yuav tsis tau zoo tagnrho uniform nto. Necked flange kev twb kev txuas los yog flange sib koom yog hais txog kev sib txuas ntawm flange, gasket thiab ntsia liaj qhov rooj raws li ib pawg ntawm cov qauv sib txuas.
Cov yeeb nkab flange yog hais txog cov flange siv rau cov kav dej hauv cov kav dej, thiab cov flanges inlet thiab qhov hluav taws xob ntawm cov khoom siv thaum siv cov khoom siv. Muaj qhov nyob ntawmflange, thiab bolts ua rau ob lub flanges nruj nreem txuas. Butt-welding flange yog ib hom yeeb nkab fittings, uas yog hais txog flange nrog caj dab thiab puag ncig cov yeeb nkab hloov thiab txuas nrog cov yeeb nkab taub qab vuam. Nws tsis yooj yim rau deform, zoo kaw thiab dav siv. Nws yog tsim rau cov kav dej uas muaj qhov hloov pauv loj hauv qhov siab lossis qhov kub thiab txias lossis cov kav dej uas muaj qhov kub thiab txias, siab kub thiab tsis kub. Qhov kom zoo dua yog tias tus nqi kuj pheej yig, thiab lub nominal siab tsis tshaj 2.5MPa;
Nws kuj tseem siv rau hauv cov kav xa dej thauj khoom kim, hluav taws xob thiab hluav taws xob tawm, nrog rau lub siab nominal txog PN16MPa. Kuj tseem muaj qhov tsis zoo, xws li cov nqi ntawm cov sijhawm ua haujlwm thiab cov khoom siv pabcuam;
3. Kev khawb yog ib qho nyuaj rau tshem tawm: tag nrho cov pickling thiab passivation, tshuaj corrosion los yog electrochemical corrosion yuav tshwm sim thiab xeb yuav tshwm sim nyob rau hauv lub xub ntiag ntawm corrosive media (txiav txim siab tshuaj), thiab carbon hlau, spatter thiab lwm yam impurities adhering rau saum npoo ntawm stainless hlau. vim khawb thiab vuam spatter tsis tuaj yeem raug tshem tawm;
Yog li yuav ua li cas daws qhov teeb meem ntawmstainless hlau flangeua?
1. Xaiv blanking, thiab ces nkag mus rau cov txheej txheem tom ntej. Txawv workpieces nyob rau hauv stainless hlau flange ua tiav nkag mus rau cov txheej txheem sib xws raws li kev ua tiav;
2. Thaum khoov, cov cuab yeej thiab zawj siv rau kev khoov yuav tsum tau txiav txim siab raws li qhov loj ntawm daim duab thiab lub thickness ntawm stainless hlau 304 seamless steel yeeb nkab. Tus yuam sij rau kev xaiv cov pwm sab saud yog kom tsis txhob muaj qhov deformation tshwm sim los ntawm kev sib tsoo ntawm lub flange thiab cov cuab yeej (Piv txwv: ib qho tseem ceeb ntawm kev sib piv) (cov qauv sib txawv ntawm cov pwm sab saud tuaj yeem siv rau tib yam khoom). Kev xaiv ntawm cov pwm qis yog txiav txim siab raws li lub thickness ntawm lub phaj. Thaum txuas lub twj tso kua mis thiab lub valve ntawm cov chaw tsim khoom flange nrog cov kav dej, cov khoom siv ntawm cov khoom siv no kuj tau ua rau cov duab flange sib raug, tseem hu ua flange txuas.
3. Nyob rau hauv thiaj li yuav welding ruaj khov, xuas nrig ntaus lub pob ntawm lub workpiece yuav tsum tau welded, uas yuav ua rau lub pob sib cuag nrog lub tiaj phaj tusyees ua ntej lub hwj chim-on vuam los xyuas kom meej qhov sib xws ntawm cua sov ntawm txhua qhov chaw, thiab kuj txiav txim siab txoj hauj lwm vuam. , uas yuav tsum tau welded. Kho lub sij hawm ua ntej nias, tuav lub sij hawm, lub sij hawm txij nkawm, thiab lub sij hawm so kom paub meej tias lub workpiece tuaj yeem ua qhov chaw welded khov kho.
