Hlau yog hlau hu ua lub hauv paus alloy. Alloys yog ob lossis ntau dua cov khoom hlau ua ke ua ke los ua ib tus hlau tshwj xeeb. Thaum peb sib tham txog cov hlau peb tab tom tham txog cov hlau hlau uas yog cov hlau sib xyaw lossis tsawg kawg yog ib qho hlau. Feem ntau cov hlau muaj ob peb coals sib xyaw ua ke hauv, txawm tias lawv cov nyiaj yuav sib txawv.

Cov kev tawm tsam ntawm Monel 2.4360 eccentric reducer rau cov kev ntxhov siab ntawm corrosion ua rau muaj kev ntxhov siab rau cov muaj sia nyob hauv lub cev tshiab.

Inconel reductants yog qhov txawv ntawm npib tsib xee, Molybdenum thiab chromium cov ntsiab lus nrog Niobium cov ntsiab lus. Nws muab cov kev tiv thaiv corrosion zoo tshaj plaws hauv chloride-muaj ib puag ncig.

Ib lub pob tw weld yeeb nkab haum yog tsim kom muaj welded rau ntawm nws cov (s) kom txuas cov yeeb nkab sib txuas ua ke thiab tso cai rau kev hloov pauv lossis lub hlab lossis xaus.

Duplex uns s31803 taub qab welded yeeb nkab fittings yog derritic Austenitic 22% Molybdenum, 5% rau 6% Nickel Alloy Stainless Hlau. Duplex unt s31803 taub qab welded cov fittings fittings yog tsim raws li cov qauv crystal ntawm cov hlau crystal.

S31803 tiv thaiv chloride corrosion cracking, thiab ob lub stainless hlau ua kom pom qhov ntsuas kub zoo tshaj plaws hauv qhov kub thiab txias.

Qib 1.440 lossis 316L yog ib tug Austenitic Stainless Hlau AISI 316 nrog heev zoo corrosion distance vim nws cov ntsiab lus chromium thiab molybdenum cov ntsiab lus thiab cov ntsiab lus muaj roj carbon. Nws lub zog hauv lub xeev tawv yog li ntawm 600 mpa rau cov kab uas loj loj, tab sis rau cov ntu me me, lub zog tuaj yeem nce los ntawm kev ua haujlwm txias.

Tsim raws li tsis ua N08825 lossis din w.nr. 2.4858, Incoloy 825 (tseem hu ua "Alloy 825") yog tus hlau-npib-chromium alloy nrog ntxiv ntawm Molybdenum, tooj thiab titanium. Qhov sib ntxiv ntawm molybdenum txhim kho nws txoj kev tiv thaiv tawm tsam hauv kev siv dej hauv dej, thaum cov ntsiab lus tooj liab muab rau cov sulfuric acid. Titanium yog ntxiv rau kev ruaj ntseg. Alloy 825 muaj qhov tseem ceeb heev rau hauv zos corrosion xws li txo thiab oxidizing cov kua qaub, thiab pitting thiab crevice corrosion. Nws yog tshwj xeeb tiv thaiv sulfuric thiab phosphoric acid. Incoloy 825 alloy yog siv rau hauv kev ua yeeb yam, petrochemical cov khoom siv, roj thiab roj av reprocessines, kua qaub ntau lawm thiab xaiv cov khoom siv.

Inconel reductants yog qhov txawv ntawm npib tsib xee, Molybdenum thiab chromium cov ntsiab lus nrog Niobium cov ntsiab lus. Nws muab cov kev tiv thaiv corrosion zoo tshaj plaws hauv chloride-muaj ib puag ncig.

Ib lub pob tw weld yeeb nkab haum yog tsim kom muaj welded rau ntawm nws cov (s) kom txuas cov yeeb nkab sib txuas ua ke thiab tso cai rau kev hloov pauv lossis lub hlab lossis xaus.

Tom qab ua haujlwm kub, aneal lub raj los ntawm tshav kub txog 1725 thiab 1850 thiab 1850 rau tsawg kawg ib nrab ib teev kom phim rau hauv dej quench. Intergranular corrosion (IGC) nyob rau hauv cov yeeb nkab fittings, kuj tseem yog intergranular corrosion (iga), yog daim ntawv corrosion (iga), yog ib qho chaw muaj crystallite ntawm cov ntaub ua rau corrosion. Uns unsctings tuaj yeem tsim tau kub tsim nrog cov rog zoo ib yam li cov uas yuav tsum tau dhau los ntawm cov hlau atusenatic.

Lub unr unic s31803 (ASTM F51) Cov lus qhia tshwj xeeb tau ua rau muaj ntau dua Superseded los ntawm Unvent S32205 (1.4462, ASTM F60). Qhov no qhia txog lawv txoj kev xav kom ua kom tiav ntawm cov khoom siv alloy, ua tsaug rau kev txhim kho AOD cov txheej txheem ntawm kev tswj hwm. Ib qho ntxiv, nws tso cai rau cuam tshuam rau cov nitrogen ntxiv qib ntxiv dua li yog tam sim no yog nyob tom qab keeb kwm. Yog li ntawd, qhov siab tshaj plaws ua tiav cov qib hloov kho kom ua kom ntau cov ntsiab lus ntawm chromium (CR), Molybdenum (mo) thiab nitrogen (n).

Stattin stainless stocks ua tiav ntau qib 304 thiab 316 fittings. Qhov ntau suav nrog 45¡u, 90¡ÃÃ thiab 180¡Ã lr luj tshib, eccentric reducer, recumic reducer, recument, ib tug flange, npog thiab pob pob.

Txhua hom yeeb nkab cov khoom muaj din, ISO, 3A, SMS, BS, Idf, DS, BPE cov qauv. Thiab cov yeeb nkab haum: 45¡Ã \ \ / 180¡ÃÃÃ ine \ / Txhua Series cov yeeb nkab fittings muaj weld, clamp, xov thiab flange plaub txoj hauv kev nrog koj cov qauv yeeb nkab txheem sib txuas.

Cov fittings kuj tseem tiv taus cov crevice corrosion hauv chloride ib puag ncig vim ntau dua molybdenum thiab npib tsib xee thiab pitting corrosion. Peb yog ib tus neeg ntawm cov neeg muag khoom hauv qib 316 txiav-rau-ntev fittings. ASTM A403 gr thiab RSP316 SS Reducer Tee yog ntau yam ntawm cov yeeb nkab fitts thiab tuaj yeem kho tau raws li cov neeg siv khoom.

Duplex steel tees feem ntau ua tau zoo nyob rau hauv ib puag ncig uas ua rau muaj kev ua ntej ntawm cov qib qis tsis kam tshaj tawm dej hiav txwv zoo dua li 316 qib. Duplex steel yog nitrogen-txhim kho stainless hlau tsim los daws cov teeb meem corrosion nrog 300 series cov hlau stainless.

Duplex hlau taub hau welded yeeb nkab fittings yog ib qho laj thawj stainless hlau, uas yog qhov laj thawj rau lawv cov tshuab hluav taws xob tsis muaj zog thiab zoo heev corrosion. Fittings tsim tawm rau ASTM A815 cov kev qhia tshwj xeeb yog tsim nrog kev tsim kho lossis vuam. Thaum A815 S31803 yog ib qho tshwj xeeb uas tso cai rau kev sau cia sib txawv lossis tsim cov haujlwm; Nws tseem npog cov fittings no, piv txwv li cov fitwlex fittings tuaj yeem tsim los ntawm cov tuam ntxhab siv kev sib txuas ntawm ob lossis ntau cov txheej txheem.

S31803 yog cov qauv sau ua ke (tsis ua haujlwm) rau thawj lub duplex stainless hlau stainless. Cov txheej txheem tsis zoo tau tsim los ntawm cov pab pawg ua lag luam hauv xyoo 1970 los txo kev tsis meej pem thaum tib almoy tau hu ua ntau yam sib txawv, thiab hloov ua lwm yam. Txhua tus hlau yog sawv cev los ntawm ib tsab ntawv ua raws li tsib tus lej, qhov twg tsab ntawv sawv cev ntawm cov hlau series, i.E. s rau stainless hlau.

Peb raug tsim tawm ButtWeld seamless thiab welded stainless hlau 304 \ / 304l flanges thiab / 304l Yeeb Nkab Khoov Ua Raws Li Cov Qauv / ASME thiab DIN Cov Qauv.

ASTM A403 WP 310 pob tw VAJ luj tshib Yog cov yeeb nkab haum siv cov kav dej sib txawv ntawm ob qho 45 degree lossis 90 degree kaum. Tseem muaj ntau qhov me me luj tshib. Lawv yog luv luv vojvoog hnab tawv me lossis ntev tshaj lub vojvoog. Qeb 310 hlau muaj tsawg kawg yog paib lub zog ntawm 205MPA thiab qhov tsawg kawg tensile lub zog ntawm 515MPA. Vim tias lub siab melting taw tes, 310 stainless hlau taub hau welded yeeb nkab fittings kuj tseem ua haujlwm nyob rau ntawm qhov kub. Cov khoom siv 310 muaj lub ntsiab lus melting ntawm 1402 degrees Celsius. Qhov no tso cai rau fittings rau kev kub siab thiab kub kev pab cuam xws li kev hloov cua sov thiab boiler Cheebtsam.
