Forged Flanges

SS 316\ / 316L flanges tuaj yeem tsim los ntawm ASTM A182 F316 lossis F316L forgings, ASTM A351 CF8M lossis CF3M castings, thiab ASTM A240 316 lossis 316L daim hlau ib ASME B16.5 thiab ASME B16.47.

Lwm cov ntsiab lus tuaj yeem muab ntxiv rau qhov sib xyaw ua ke ntawm cov hlau ore los tsim ntau hom hlau. Txhua hom hlau tuaj yeem siv rau kev lag luam tshwj xeeb xws li kev tsim kho mus rau kev txhim kho cov txheej txheem.

Flanges feem ntau yog welded los yog threaded. Flange pob qij txha yog tsim los ntawm bolting ob flanges ua ke nrog lub gasket ntawm lawv los muab lub foob.

Incoloy 825 Flanges yog ib hom flanges uas muaj kev tiv thaiv zoo rau oxidizing thiab txo cov kua qaub.

Peb stainless hlau 316 qhov (socket) weld flanges tuaj yeem yooj yim welded thiab machined los ntawm cov txheej txheem khw fabrication. Rau feem ntau cov txheej txheem ua haujlwm kub, cov hlau tsis muaj steel 316L lap joint flanges raug pom zoo rau kev tsim ntawm 1700¡ãF - 2200¡ãF (927¡ã - 1204¡ãC) Peb stainless hlau 316 ntiv nplhaib sib koom ua ke flanges yog cov ductile heev thiab yooj yim rau kev tsim, ua haujlwm hardening tshwm sim thaum deformation yog ib qho yooj yim.

Kev ua haujlwm txias ua haujlwm yuav ua rau muaj zog thiab tawv ntawm cov hlau tsis muaj steel 316L qhov muag tsis pom flanges thiab yuav ua rau lawv sib nqus me ntsis. Flanges feem ntau yog welded los yog threaded. Flange pob qij txha yog tsim los ntawm bolting ob flanges ua ke nrog lub gasket ntawm lawv los muab lub foob.

Stainless hlau 316 flanges yog tsim los ntawm chrome-nickel-molybdenum alloy thiab feem ntau yog siv rau hauv cov xwm txheej uas muaj chloride ion corrosion. Qhov sib ntxiv ntawm molybdenum ua rau cov khoom siv tiv thaiv corrosion, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig uas muaj chloride. 316L stainless hlau flanges yog tus qauv molybdenum qib, thib ob tsuas yog 304 hauv austenitic stainless hlau.

316l muaj kev sib sau zoo thiab vuam yam ntxwv. Nws yog yooj yim braked los yog dov rau hauv ntau qhov chaw siv rau hauv kev lag luam, kev tsim kho thiab kev thauj mus los.

UNS Peb muab ntau hom 304 SS flanges xws li SS 304 Reducer Flange, SS 304 Slip Flange, SS 304 Orifice Flange, SS 304 Nipo-Flange, SS 304 Lose Flange, SS 304 Lap-Joint Flange thiab. Peb ua cov kev kuaj xyuas zoo ntawm peb cov khoom kom ntseeg tau tias lawv cov kav ntev thiab kev ntseeg tau.

Flanges ua los ntawm stainless hlau yog hu ua "stainless steel 304 flanges", kuj hu ua "SS 304 flanges". Cov qauv khoom siv thiab qib suav nrog ASTM A182 Qib F304\ / L thiab F316\ / L, nrog rau kev ntsuas siab ntawm 150 txog 2500 thiab 300 txog 600, raws li.

Stainless hlau 304 flanges yog ib txoj hauv kev sib txuas cov kav dej, lub valve, twj thiab lwm yam khoom siv los tsim cov kav dej. Nws kuj pab txhawb kev tu, tshuaj xyuas lossis hloov kho. Stainless hlau 304 flanges yog tsim los ntawm 18\ / 8 chrome-nickel austenitic stainless hlau alloy feem ntau siv hauv cov ntawv thov stainless hlau.

Lawv tuaj yeem siv rau hauv cov hlab ntsha siab nrog lub phab ntsa kub ntawm 800 degrees F. Lawv kuj muaj kev tiv thaiv zoo rau kev ntxhov siab corrosion tawg.

Qib 304 stainless hlau yog tus qauv "18\/8" stainless hlau; nws yog cov khoom siv ntau yam thiab dav siv stainless hlau muaj nyob rau hauv ntau yam khoom, cov ntaub ntawv thiab tiav ntau dua li lwm yam.

ASTM A182 316L spacer nplhaib impervious rau intergranular corrosion

ASTM B424 UNS N08825 spacer nplhaib tshwj xeeb ua haujlwm rau ntau qhov chaw corrosive

Feem ntau, qhov corrosion kuj ntawm peb stainless hlau 316 taub qab vuam flanges yog hais txog tib yam nyob rau hauv feem ntau corrosive ib puag ncig.

Lawv tuaj yeem tiv taus aqueous corrosion thiab li no tuaj yeem siv rau hauv marine daim ntaub ntawv.

A182 F316L tshwj xeeb flange hauv cov ntawv thov uas muaj feem cuam tshuam rau cov tshuaj chloride

Nyob rau hauv ib puag ncig uas muaj corrosive txaus los ua intergranular corrosion nyob rau hauv welds thiab tshav kub cuam tshuam cheeb tsam, cov no yuav tsum siv stainless hlau UNS S31600\ / S31603 dig muag flanges vim nws cov ntsiab lus carbon tsawg.

Peb stainless hlau 316 qhov (socket) weld flanges tuaj yeem yooj yim welded thiab machined los ntawm cov txheej txheem khw fabrication.

Flanges yog siv los txuas 2 cov kav dej lossis cov raj. Lawv yog tsim los ntawm cov khoom sib txawv nyob ntawm qhov kawg siv.

Nyob rau hauv daim ntawv ore, qhov concentration ntawm cov pa roj carbon ntau tshaj qhov xav tau rau cov khoom tshwj xeeb ntawm cov hlau. Yog li ntawd, steelmakers reprocess cov hlau molten kom txo cov ntsiab lus carbon rau qhov xav tau.

Cov stainless hlau 316L threaded flanges ua tau zoo hauv kev pabcuam dej tshiab txawm tias muaj cov tshuaj chloride siab.

Stainless hlau 316\ / 316L flanges tuaj yeem ua los ntawm kub forging lossis casting. Qhov muag tsis pom los yog zawv zawg phaj flanges tsis muaj hubs tuaj yeem raug machined ncaj qha los ntawm lub phaj. Flanges yuav tsum tau muab tshuaj kho tsis pub tsawg tshaj 1900¡ãF [1040¡ãC] thiab tom qab ntawd quenched hauv dej txias lossis lwm txoj kev txias txias.

Alloy 825 (UNS N08825) yog austenitic nickel-hlau-chromium alloy nrog ntxiv ntawm molybdenum, tooj liab thiab titanium.

ASTM B564 UNS N08825? muab cov khoom siv kho tshuab zoo nyob rau hauv chav tsev kub nrog rau qhov kub thiab txias.

Lawv yog fabricated los txhim kho lawv kev tiv thaiv corrosion thiab huv si rau weld. Lawv tiv taus chloride pitting thiab rhiab heev.
