Muaj cov kev ntsuas sib txawv rau cov flanges raws li qhov system ntsuas. Nyob rau hauv tus qauv ANSI, cov kev kawm siab siab ntau ntawm chav kawm 150 los ntawm chav kawm 2500.

Ib txoj kev sib koom ua ke flanged yog tsim ntawm peb cais thiab ywj siab yog tias muaj kev sib cuam tshuam; Cov flanges, lub gaskets, thiab cov bolting; Uas tau sib sau los ntawm kev cuam tshuam lwm tus cuam tshuam, fitter. Cov kev tswj tshwj xeeb yuav tsum muaj nyob rau hauv kev xaiv thiab kev xaiv ntawm tag nrho cov muaj cov ntsiab lus kom muaj kev sib koom ua ke, uas tau siv tau xau nruj.

Ib Flange yog ib qho kev tawm tsam, daim di ncauj lossis sab nraud, tog twg los sab nraud lossis sab hauv, uas yog cov nqaj hlau xws li ib tug t-nqaj); Rau cov ntawv yooj yim tau yooj yim \ / hloov ntawm kev sib cuag nrog lwm yam khoom (raws li flange thaum kawg ntawm cov yeeb nkab, chav dej lub tog raj kheej, lossis ntawm lub ntsej muag lub koob yees duab); Los yog rau kev ruaj khov thiab taw qhia kev txav ntawm lub tshuab lossis nws cov ntu (raws li sab hauv flange ntawm tsheb ciav hlau lossis lub log los ntawm kev khiav tawm ntawm cov ciav hlau). Lo lus "Flange" kuj yog siv rau hom cuab yeej siv los ua cov flanges.

Cov alloy txawv no yog siv hauv cov roj thiab roj kev tshawb nrhiav thiab tseem siv hauv kev lag luam ua lag luam. Cov cuab yeej ua lag luam tshaj plaws siv Duplex 2205. Kuj tseem siv los ntawm kev lag luam cia thiab tsheb thauj mus los. Pulp thiab cov ntawv luam tawm, tso tsheb hlau luam thiab ntawv ua kua thiab ntawv tshuab kuj siv duplex 2205. Nws yog qhov zoo rau kev siv hauv ib puag ncig marine.

Duplex steel flanges yog tsim los txhim kho kev pitting caterposion, siab zog, kev nyuaj siab corrosion, crevice corrosion thiab tawg. Duplex Steel zawv zawg Flanges tiv thaiv sulfide kev nyuaj siab corrosion thiab chloride ib puag ncig. Duplex Steel tiaj Flanges yog ib qho tseem ceeb ntawm cov tsev neeg ob lub flange.
Lub Flange yog qhov thib ob feem ntau siv koom nrog txoj kev tom qab selding. Kev siv flanges tau siv thaum cov pob qij txha xav tau dismantling. Nws muab kev hloov tau rau kev saib xyuas. Flange txuas cov yeeb nkab nrog ntau yam khoom siv thiab li qub. Breakup Flanges tau ntxiv rau hauv cov raj xa hluav taws yog tias kev saib xyuas tsis tu ncua thaum lub sijhawm cog ntoo.
Duplex 2205 thiab super duplex 2507 stainless hlau taub qab weltealed tawm lub zog ntawm cov hlau tsis muaj txiaj ntsig xws li 304 thiab 316 Stainless Hlau Weld Flanges. Vim tias qhov no, Duplex 2205 thiab super ruplex 2507 steel qeb siv rau pob tw weld flange yog qib ntau dua ntawm ob.

Duplex stainless tus khub qib yog lub npe denplex vim tias cov qib ob flange sib npaug muaj ob-theem microstructure. Qhov no ob-theem microstructure muaj cov ferritic thiab ustenitic stainless hlau-zoo li nplej. Raws li lub npe qhia, lub duplex kev tsim kho muab cov duplex stainless ntsaws qhov hluav taws xob muaj ntau yam khoom txaus nyiam.

S32205 yog ob theem ob theem steel nrog ze li ntawm cov sib npaug ntawm cov ooustenite thiab ferrite hauv nws cov tshuaj lom neeg muaj pes tsawg leeg. Qhov kev sib xyaw ua ke no ua rau muaj zog tshaj dua cov qauv siv tshuaj tiv thaiv cov hlau. Lub khawm ob lub flatx s31803 lub nplhaib haum rau Flange yog cov carbon qis version thiab yog cov tshuaj tiv thaiv kab mob.

Nws muaj lub zog siab thiab zoo heev corrosion tsis kam. Duplex stainless hlau flanges muaj kev sib txuam zoo heev corranular. Nws muaj qhov ua tau zoo heev rau corrosion cracking kev ntxhov siab txawm nyob hauv cov sulfide thiab chloride ib puag ncig.

SUPERX STEES 1.4410 Flanges yog muaj cov nqi sib cais tsawg dua li kev tiv thaiv kab mob corrosion thiab kev ua kom zoo nkauj vim tias muaj zog ua kom zoo.

ASTM A182 Duplex Stainless Hlau Flanges nrog siab tsis kam rau kev ntxhov siab thiab kev mob corrosion

Super Duplex flanges yog qhov zoo tagnrho rau kev pabcuam hauv cov chaw muaj kev tiv thaiv hnyav xws li ntug dej hiav txwv thiab marine. Nws tseem yog tshwj xeeb tiv thaiv chloride SCC. Flanges muab sib npaug pitting kuj, kom ntseeg tau zoo heev pitting kuj. Tag nrho cov khoom lag luam muaj lub zog kuaj, suav nrog pitting corrosion kev sim, kev kuaj tawv, tshuaj ntsuam thiab ntsuas micro thiab ntau dua.

Dual-theem hlau pob tw-welded tsa lub ntsej muag lub ntsej muag flanges muab kev txiav kom zoo heev thiab kev hnav khaub ncaws nce thiab teeb tsa lub sijhawm.

Nws ncav cuag cov theem sib npaug ntawm Austenite thiab ferrite nyob rau hauv ntxhib ib yam ntim ntim.

Duplex stainless yog sib xyaw microstructure ntawm Austeniture ntawm Austeniture ntawm Austenitic thiab Ferrite (50) uas tau txhim kho cov hlau qib siab nrog corrosion tsis kam.

A182 F53 cov ntaub ntawv qhia tau zoo heev corrosion tsis kam.

Duplex stainless hlau s31803 \ / s32205 \ nrog zoo sulfide kev nyuaj siab corrosion, muaj lub zog zoo thiab zoo heev kev cuam tshuam todlaj. These dual phase steel S31803 slip flanges are chemically balanced to produce a microstructure of approximately 50\/50 ferrite to austenite ratio.

Raws li nrog txhua tus stainless hlau qib, corrosion tsis kam ntawm cov hlau lossis alloy nyob ntawm feem ntau ntawm cov hlau, nyob rau hauv cov ntaub ntawv no stainless hlau. Rau kev tiv thaiv mus rau chloride pitting thiab crevice corrosion, cov ntsiab lus ntawm cov ntsiab lus xws li chromium, molybdenum thiab nitrogen yog qhov tseem ceeb tshaj plaws.

Cov khoom siv S32205 DuPlex Asme asme sa182 pob tw Weld Flanges yog tsim nyog rau dej hiav txwv thiab cov khoom siv hluav taws xob tuaj yeem tiv thaiv kom sov txog 600,000Ãf, thaum tseem muaj cov yam ntxwv zoo.

Duplex cov hlau muaj siab tiv taus ntau hom corrosion. Duplex steel s31803 yog ib qho tsis tshua muaj xeb-tiv taus, ua haujlwm-alloy. Duplex steel s31803 pob tw weld flanges muaj cov khoom kub siab.

Super Duplex flanges yog qhov zoo tagnrho rau kev pabcuam hauv cov chaw muaj kev tiv thaiv hnyav xws li ntug dej hiav txwv thiab marine. Nws tseem yog tshwj xeeb tiv thaiv chloride SCC. Flanges muab sib npaug pitting kuj, kom ntseeg tau zoo heev pitting kuj. Tag nrho cov khoom lag luam muaj lub zog kuaj, suav nrog pitting corrosion kev sim, kev kuaj tawv, tshuaj ntsuam thiab ntsuas micro thiab ntau dua.

DupleX Steel Flanges tau siv dav hauv kev siv tshuab siv, kev lag luam tshuab thiab tsheb lag luam hauv tsheb. Duplex steel s31803 lap flanges yog qhov zoo tagnrho rau cov ntawv thov ua kom zoo dua li hom 316 thiab lub zog kub zoo. Peb muaj lub duplex steel s31803 \ / s32205 flanges hauv Tshuag. Duplex steel flanges yog ib txwm siv hauv tshuaj, petrochemical, thiab kev lag luam fais fab.

Cov qib no tau zoo tshaj plaws rau kev pabcuam yooj yim flange kev sib txuas, tab sis me ntsis tsawg dua yog li thaum tsim ib tug qauv sib txuas. Hmoov zoo, kev ua haujlwm ntawm duplex rau hauv cov qauv sib zog thiab cov sib npaug ntawm cov qauv siv hluav taws xob ntau rau cov khoom siv me me hauv cov ntawv thov corbive.

Duplex 2205, tsis yog S32205, yog cov khoom siv stainless hlau uas muaj cov microstructure muaj sib npaug muaj sib npaug ntawm cov ferrite thiab austenite. Cov qib no yog hom nrov tshaj plaws, thiab ob hom khoom siv ob-theem no yog qhov tseem ceeb tshaj 316 stainless hlau nyob rau hauv cov nqe lus muaj zog thiab corrosion tsis kam.
