Zoo ib yam li 304h, Qib 316H yog cov pa roj mariant ntawm qib 316 stainless hlau, uas muaj ib feem tsawg feem pua ​​ntawm Molybdenum rau kev siv hauv kev siv marine qib. Cov Austenic qib ntawm stainless siv cov ntsiab lus ntau cov roj carbon ntau dua rau kev siv ntau dua qhov kev pabcuam kub, ntau yam li nws tau ntxim nyiam qib 304H. Txawm hais tias nws tsis tshua siv, nws tseem yog kev lag luam muaj.

Ib lub flange tuaj yeem ua ib lub phaj rau npog lossis kaw qhov kawg ntawm cov yeeb nkab. Qhov no yog hu ua tus dig muag flange. Yog li, flanges tau txiav txim siab yog nyob rau sab hauv cov khoom uas tau siv los txhawb lwm lub tshuab tshuab.

Steel flanges muab cov yooj yim rau kev ntxuav, kuaj lossis hloov kho. Lawv feem ntau tuaj hauv cov duab sib piv tab sis lawv tuaj yeem tuaj hauv cov ntawv square thiab duab plaub. Cov flanges tau koom nrog txhua lwm yam los ntawm kev sib koom tes los ntawm cov kav dej los ntawm vuam lossis xov thiab tsim rau cov kev ntsuas tshwj xeeb; 150LB, 300LB, 400LB, 600LB, 900lB, 1500lb thiab 2500lb.

ASTM A403 WPRP3H YPRICK FITTINGS txhais tau tias cov yeeb nkab fittings uas cov khoom yog ittm A403 cov khoom siv tau siv tag nrho los ntawm kev tswj hwm era kev lag luam.

Muaj ntau cov pa roj carbon nyob hauv 316 stainless hlau dua 316L. Qhov no yooj yim kom nco ntsoov vim tias qhov l sawv rau "tsawg". Tab sis txawm nrog cov ntsiab lus muaj roj teeb qis, 316L yog qhov zoo heev li 316 hauv yuav luag txhua txoj kev. Cov nqi yog qhov zoo heev, thiab ob qho tib si yog ruaj, corrosion-resistant, thiab ib qho kev xaiv zoo rau cov xwm txheej siab.

321h tau txais txiaj ntsig zoo rau kev cuam tshuam hauv qab no raug rau qhov kub hauv lub chromium carbide nag lossis daus los ntawm 800 rau 1500 f (416 c).

Hom 304 stainless hlau muaj npe rau nws cov muaj pes tsawg leeg, uas suav nrog 18% chromium thiab 8% npib tsib xee. Qhov no stainless hlau muaj kev ua kom zoo thiab weldability. Vim nws muaj pes tsawg leeg, stainless hlau 304 flanges yog cov corrosion heev tiv taus thiab ruaj khov.
316L 1.4401 tus yeeb nkab stainless hlau yog ib qho kev xaiv yeeb nkab zoo heev thiab cov yeeb nkab ruaj khov siv hauv ntau cov ntawv siv. Qhov no ss s31603 yeeb nkab yog tsim los ntawm cov hlau zoo 316L stainless ua rau corrosion, oxidation thiab staining rau cov chaw hnyav lossis kev siv ntxhov siab.

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 no yog cov qib feem ntau ntawm cov hlau stainless. 18% CR, 8% NI, Nonmagnetic. Peb muab cov ntaub ntawv qib ob uas muaj cov ntsiab lus roj haloility uas cov ntsiab lus carbon tsawg uas yog qhov ntsuas kub siab dua (ntau dua 800degf), 304H yuav pom zoo.
304 Piping spools yog tsim los ntawm 304 stainless hlau, ib qho khoom siv nrov thiab nrov tshaj plaws hauv ntau cov ntawv thov uas xav tau kev tiv thaiv kom xeb thiab oxidation. Cov kev tshaj lij no yog preooss siv cov machinery thiab cov txheej txheem tshwj xeeb, uas paub meej tias lawv muaj tseeb thiab ntseeg tau.
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).

Cov khoom lag luam almoy inconoy tsim yog kuaj rau ntau cov neeg kho mob zoo li lub zog hluav taws xob zoo ib yam li cov khoom siv hluav taws xob tsis yog hydrostatic. Cov kub tau ua tiav lossis txias ua haujlwm tag nrho yog tsim nyog rau kev siv hauv cov ntawv thov uas xav tau qhov kev xav tau ntawm corrosion tsis kam ntawm thaj chaw. Cov kav dej tsis tu ncua muaj kev cuam tshuam rau kev cuam tshuam corrosion.

SS 304 tubing yog ib tug stainless hlau raj ua rau cov ntawv thov sib txawv. Muaj cov qhab nia sib txawv hauv cov hlab me .Qhov hlau stainless 304 raj yog ib qho ntawm feem ntau siv siv vim tias tus nqi qis

Kev txhawb nqa lossis ntev nthuav dav ntawm hom 316L rau 800-1500ÃF (427-816¡Ãc) yuav muaj kev phom sij. Ib qho ntxiv, kev nyuaj siab kev daws teeb meem nruab nrab ntawm 100-1500ÃF (593-816¡Ãc) tej zaum yuav ua rau hom me me embrittlitty.

Stainless 316 qib raug nqi ntau vim lawv zoo corrosion tsis kam. Qhov kev kawm qib siab ntau tshaj plaws yog qhov tshwj xeeb tshaj yog pom zoo rau cov ntawv thov uas cov alloy raug rau chlorinated kev daws teeb meem thiab chlorides, suav nrog dej hiav txwv.

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.

904L stainless hlau phaj yog ib tug super ustenitic stainless hlau uas muab me ntsis rau siab corrosion tsis kam nyob rau ntau thaj chaw. Kev sib xyaw ntawm cov chromium thiab cov ntsiab lus npib tsib xee, nrog rau kev sib ntxiv ntawm Molybdenum thiab tooj liab, muab cov tshuaj tiv thaiv corrosion zoo tshaj plaws. Nrog npib tsib xee 25% thiab molybdenum 4.5%, Astm B625 tsis tawm ntawm cov chloride kev ntxhov siab, pitting thiab dav dav rau 316L thiab 317l.
