Yeeb nkab nrog flange

Lub siab chromium cov ntsiab lus txhawb nqa thiab saib xyuas zaj duab xis passive uas tiv thaiv cov khoom hauv ntau qhov chaw muaj kev nyab xeeb.

316 Stainless hlau muaj ntau cov pa roj carbon ntau dua 316L. Qhov no yooj yim kom nco ntsoov, zoo li L sawv rau "tsawg."

Cov kab phib kab yog li cas los ntawm tus naj npawb ntawm cov kav dej nyoos thiab cov yeeb nkab fittings (piv txwv li laujkes, flanges, tees, thiab lwm yam) hauv cov khw fabrication.

Alloy 904L Outperforms Lwm yam Austenitic stainless hlau vim muaj qib siab ntawm alloy thiab molybdenum.

316L kuj yog tus qauv zoo kawg rau kev kub siab, kev siv ntau xeb, uas yog vim li cas nws thiaj nrov rau kev siv hauv kev tsim kho thiab marine ua haujlwm.

Alloy 347h (untalial s3409) Phaj Stainless Hlau yog cov carbon ntau dua (0.04 ¨C 0.10) version ntawm alloy.

Lub durability ntawm cov hlau yog ib qho zoo tshaj plaws ntawm cov raj xa hluav taws xob. Nws muaj zog thiab nws tuaj yeem tiv thaiv cov kev ntsuas, qhov kub thiab txias, hnyav hnyav, thiab kev co. Nws kuj muaj cov cim hloov pauv tshwj xeeb uas muab qhov txuas ntxiv.

Qhov sib ntxiv ntawm tus qauv rau qib no muab nws zoo dua corrosion tsis kam tshaj li cov pa chromium-tsib xee stomfuric, phosphoric thiab acetic acids. Txawm li cas los xij, kev siv ntawm hydrochloric acid yog txwv.

304 Stainless hlau tsis muaj ib qho tsis muaj zog: Nws yog kev ntxim rau corrosion los ntawm cov tshuaj chloride lossis cov dej qab ntsev xws li ntug dej hiav txwv.

Thaum xaiv cov hlau tsis xeb uas yuav tsum tau ua kom haum ib puag ncig, cov hlau tsis huv stainless hlau feem ntau siv.

316L Cov Khoom Ua Ntej muaj zog ntawm cov chaw kub

Lub stainless hlau fab sib txaws cov spool yog pab rau cov neeg siv khoom uas lawv tsis nco qab ib feem twg thiab lawv tshem tawm cov teeb meem ntawm cov khoom seem.

npib tsib xee alloy haastelloy c276 nrog flanges

316L, yog qhov kev xaiv zoo dua rau ib qhov project uas yuav tsum muaj ntau tus vuam vim 316 yog qhov ntxim nyiam ntau dua 316l (corrosion nyob rau hauv weld).

Alloy 347 (Unsen S34700) yog columbium stabilized ustenitic steelion steelion tsis kam thiab qee qhov zoo dua nyob rau hauv cov mob oxidizing zoo tshaj 321 (unc unical S32100).

Cov hlau stainless 904l \ / 1.4539 cov khoom siv tau los ua cov khoom kub thiab cov hlau thiab cov khoom siv sib tw, nrog rau kev siv roj ntsha thiab welded

Ob lub cim tsis muaj stainless hlau feem ntau yog 304 thiab 316. Txhim kho qhov sib txawv ntawm cov neeg corrosion, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig nrog ntau qhov ntsev lossis tshuaj chloride kis.

904L Qib Stainless Hlau tsis zoo li lwm cov hlau. Vim nws cov roj, molybdenum, npib tsib xee thiab tooj liab, 904l steel nta mus rau corrosion, xeb thiab acids.

Lub alloy muaj cov oxidation zoo tsis kam thiab creep lub zog mus rau 1500¡Ãf (816¡Ãc). Nws kuj tseem muaj qhov ntsuas kub zoo tsawg.

Cov kav dej nyoos raug txiav rau cov uas yuav tsum tau loj thiab cov txav nrog cov yeeb nkab fittings rau lub rooj haum, qhov twg qee qhov sib txuas ua ke (i.e. txuas ib ntus). Lub txiaj ntsig sub-sib dhos (ib feem ntawm qhov kawg cov kab ua ntej cov zaub mov) txuas ntxiv nrog cov chaw sib txuas) ua ntej nws rov qab mus rau lub rooj sib npaug thiab tau ua kom haum nrog lwm cov kab noj mov.

Qhov no cov hlau stainless yeeb nkab feem ntau flanged los pab txhawb kev sib txuas nrog lwm cov kev lag luam xws li cov khoom siv hluav taws xob zoo li yuav tsum muaj cov piping nthuav dav.

304 Stainless hlau yog daim ntawv feem ntau ntawm cov hlau stainless hauv ntiaj teb vim nws zoo heev corrosion thiab tus nqi. Nws muaj 16% rau 24% chromium chromium thiab txog 35% npib tsib xee, ntxiv rau cov pa roj carbon thiab manganese.

Peb tsim cov khoom siv rau cov khoom siv thiab. Thaum cov neeg yuav khoom xav tau cov khoom sib txawv ua ntej kev teeb tsa, daim ntawv thov ntawm cov khoom siv ua ke ua ke ua ke yog hu ua piping spool thov. Muaj cov hlau stainless hlau spools cov khoom zoo li lwm cov khoom siv tau cov kab ua haujlwm hauv kev siv.

Cov leeg cov kab pheebsuab feem ntau yog siv rau hauv pob zeb ua qauv kom paub tseeb tias cov fittings kom ntseeg tau tias yog qhov chaw ua ntej pouring pob zeb ua ntej.

Nws muaj qhov ua tau zoo heev rau intergranular corrosion tom qab kis tau kub hauv cov chromium carbide nag los nag (400 ¨c 816¡Ãc).?

Qhov chaw saum npoo ntawm cov cheebtsam yuav tsum yog txawm thiab qhov tsis sib xws yuav tsum raug tshem tawm. Kev khi cov txheej txheem yog siv rau cov npoo ntawm cov seem. Lub tshuab sib tsoo yog ua haujlwm rau cov txheej txheem beveling. Hom kev sib tsoo tshuab rau beveling txawv rau stainless hlau Cheebtsam thiab cov khoom siv hlau.

Ib txoj kev haum thiab vuam cov txheej txheem yuav tsum tau siv tom qab ntug ua tiav ntawm feem. Yog li ntawd, rau cov hlau stainless thiab carbon hlau yeeb nkab ncauj, ntu tuaj yeem nyob rau ntawm cov hauv paus steel lossis hauv paus ntoo. Tsis tas li ntawd, ib qho kev tiv tauj ntawm cov roj carbon hlau thiab hlau yuav tsum tau txo qis.

Steel Yeeb Nkab Quav Kuj tseem raug xa mus raws li prefabricated cov khoom siv xws li cov kav dej, flanges thiab lawv tau mounted thiab lawv tau mounted thaum lub sij hawm xa mus rau kev tsim khoom.

Muaj ntau cov khoom siv txawv cov khoom siv uas siv los tsim cov spools no. Lub 304 stainless hlau yog cov qib siv ntau tshaj plaws. Lub ntsej muag huv stainless 304 tri clamp spool yog tsim los ntawm cov khoom no thiab muaj 3 clamps haum rau kev yooj yim ntawm cov qhua tuaj noj mov. Peb tseem muab cov kev daws teeb meem rau peb cov neeg siv khoom. Thov hu rau peb rau koj cov kev xav tau.

Rau cov khoom ntawm cov dej thiab cov roj av nrog, cov kav hlau steel yog qhov tseem ceeb kav kav. Lawv siv nyob rau hauv ntau lub tsev thiab kev lag luam los hloov cov roj nkev lossis roj roj. Lawv kuj tau siv rau hluav taws sprinkler cov tshuab tawm ntawm lawv qhov kev tiv thaiv kub.
