Peb tab tom muaj pab pawg ntawm cov kws tshaj lij thiab kev paub txog uas tau saib thiab saib xyuas cov txheej txheem tag nrho kom tsis txhob muaj qhov tsis xws luag. SS 316 \ / ss 316L Compression Tube Fittings yog tsim nyog siv tshuaj lom neeg, npias, dai kom zoo nkauj, thiab kev lag luam dej. Vim tias cov molybdenum ntxiv, SS 316 compression fittings muaj lub zog zoo dua li qib xyoo 304. Peb muab cov khoom lag luam zoo tshaj plaws, rooj sib tham thiab peb cov neeg tau txais kev cia siab.

Alloy 20 tseem muaj lub npe hu ua N08020 uas yog lub stainless hlau uas muaj cov loj sib txawv nrog kev tiv thaiv zoo heev rau kev ntxhov siab thiab sulfuric acid. Cov qib allolo no muaj ntau cov ntsiab xws li tooj liab, npib tsib xee; Chromium thiab Molybdenum uas ua ke pab rau kev muab cov corrosion, tiv taus rau corrosion thiab pitting.
Hom 317L yog molybdenum-muaj cov roj me me uas muaj cov hlau ua kom zoo rau hom 316L hauv kev txhim kho corrosive ib puag ncig, tshwj xeeb yog cov muaj chlorides lossis lwm yam. Cov pa roj carbon tsawg tsawg hom 317L yuav tsum tau welded yam tsis muaj qhov tsis txaus ntseeg los ntawm cov chromium carbide nag lossis daus hauv cov ciaj ciam. Hom 317L tsis yog kev sib nqus nyob rau hauv anealed mob tab sis tej zaum yuav dhau los ua kev sib nqus me ntsis raws li kev vuam.

Rau kev huv 90 degree lub luj tshib, peb tuaj yeem muab cov pob zeb khov kho lub luj tshib, cov kua txiv, npias, thiab lwm yam tshuaj.

Ib qho tee yog ib qho yeeb nkab haum uas yog siv los faib cov ntws loj mus rau hauv ob ntws lossis kom sib txuas los ntawm ob ntws. Vim tias daim ntawv ntawm cov yeeb nkab Tee zoo li tus niam ntawv "T". Thawj cov yeeb nkab ntawm Tee yog nquag hu ua lub ntsiab yeeb nkab lossis khiav yeeb nkab, thiab lwm tus raws li nws cov ceg.

Monel 400 yog npib tsib xee-tooj ​​liab (kwv yees li ntawm 67% Kev du dua thiab thermal conductivity zoo tagnrho rau cov khoom siv hiav txwv.

Lub xub ntiag ntawm no sigma theem hauv cov theem steel hlau yog qhov cuam tshuam rau cov khoom siv xeb, nws tau txo cov khoom xws li cuam tshuam ntawm chav tsev kub.

Feem ntau, hom 316 qib yuav raug suav tias muaj kev sib luag zoo nyob rau hauv ib puag ncig ib puag ncig. Ib qho kev zam tseem ceeb yog intergranular corrosion nyob rau hauv lub tshav kub-cuam tshuam rau welds nyob rau hauv cov chaw muaj kev sib txuam txaus. Hauv cov xov xwm zoo li no, hom 316L yog qhov tsim nyog rau kev siv vuam dua hom 316 vim tias cov ntsiab lus muaj roj carbon ntau ntxiv rau hauv kev txhim kho corrosion.

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 hau kev uas tsis yog feem ntau cia siab rau kev siv yeeb nkab lub zog los pab coj cov yeeb nkab rau nws cov txheej txheem kawg thaum siv cua sov kom txo tau lub zog.

316 yog ib tug tswv cuab ntawm 18 auxi \ / 8 chromium npib tsib xee ntawm Austenitic Stainless kuj, tshwj xeeb rau hauv zos corrosion hauv chloride hauv chloride nyob rau hauv corroside muaj chaw ib puag ncig.

Nickel loj tshaj plaws Alloy C22 Lub Cim Chaw Tsim Tshuaj nyob hauv Suav teb as per B16.9 tus qauv ittm thiab

Txij xyoo 2008, vim yog qhov zoo tshaj plaws corrosion tsis kam ntawm dual-theem hlau pob tw-welded yeeb nkab fittings, kev ua lag luam tau nyob hauv qhov kev thov siab. Nws tiv siab intergranular thiab crevice corrosion. Nws tseem qhia tseem ceeb pitting kuj. Chloride kev ntxhov siab corrosion kuj yooj yim daws nrog ob 2205 ntawm 150 degrees Celsius.

Lub tshuab hluav taws xob stainless hlau yog cov khoom ntawm kev xaiv rau nqa cov tshuaj corrosive lossis cov roj av, tshwj xeeb yog qhov kev ntsuas siab, siab dua ib puag ncig muaj kev koom tes. Raws li qhov tshwm sim ntawm kev ua kom zoo nkauj ntawm cov hlau stainless, cov yeeb nkab feem ntau siv hauv cov ntawv thov archectural.

316 yog ib tug tswv cuab ntawm 18 auxi \ / 8 chromium npib tsib xee ntawm Austenitic Stainless kuj, tshwj xeeb rau hauv zos corrosion hauv chloride hauv chloride nyob rau hauv corroside muaj chaw ib puag ncig.

C276 Luj tshib tau zoo heev corrosion tsis kam rau ntau yam ntawm cov kua roj kub thiab muaj kev txo qis hauv cov ntawv thov sulfuric kub thiab hydrochloric.

ASTM A860 Why 52 Fittings tau ua los ntawm cov roj carbon ntau, tus tub rog, tooj, lub nroog tooj liab, cov roj ntsha li ntawm A860 Whbake yog ib qho kev daws teeb meem.

304 Stainless hlau yog qhov feem ntau cov hlau tsis muaj. Cov hlau muaj ob txoj kev chromium (nruab nrab ntawm 18% thiab 20%) thiab thib pua (nruab nrab ntawm 8%) [1] cov hlau uas yog cov qauv hlau tseem ceeb. Nws yog Austenitic stainless hlau.When nws los txog siv, SS304 tuaj yeem pom hauv chav ua noj hauv chav dej thiab lwm yam khoom siv xws li toaster thiab microwave ncu. SS304 kuj yog siv los ua kom cov hlab ntsha siab, lub log npog zoo li rau kev ua lub tsev kws ua liaj ua teb.

Stainless hlau yog ib qho alloy ntawm cov hlau uas tiv taus xeb. Nws muaj tsawg kawg yog 11% chromium thiab tej zaum yuav muaj cov ntsiab lus xws li carbon, lwm yam tsis yog lwm yam kom tau lwm yam uas xav tau. Stainless hlau qhov tsis kam rau corrosion tau los ntawm cov chromium, uas ua cov yeeb yaj kiab passive uas tuaj yeem tiv thaiv cov khoom thiab kho tus kheej nyob rau hauv lub xub ntiag ntawm oxygen.

Qhov no npib tsib xee-tooj ​​liab xwb yog daus ntau dua vim kev sib ntxiv ntawm txhuas thiab titanium. Nws ua ke cov xeb tiv thaiv ntawm Monel 400 nrog cov txiaj ntsig ntxiv ntawm cov txiaj ntsig zoo dua thiab hardness (muab tau los ntawm nws lub hnub nyoog-zog). Monel K-500 tseem muaj lub npe tseem ceeb rau nws yooj yim ntawm cov ntaub ua piv rau lwm tus supalloys, thiab qhov tseeb tias nws yog qhov tseem ceeb tsis yog qhov kub kub.

Stainless hlau yeeb nkab fittings muaj 10% npib tsib xee thiab cov ntsiab lus chromium siab. Cov neeg tsim khoom ntawm cov fittings stainless tsim cov fittings ua ntxiv ntawm kev sib ntxiv ntawm mangphorus, sitphorus, silicon thiab sulfur ntxiv rau ob lub ntsiab tseem ceeb.

Rau cov ntawv sau zeb hauv av uas xav tau cov qib qis dua uas tsis muaj cov xeb txaus tiv thaiv. Raws li 22% chromium cov ntsiab lus, lawv muaj cov ustenitic: Ferritic microstructure uas muaj zog dua, corrosion tsis kam thiab nqi-ua hauj lwm zoo.

Nyob rau tib lub sijhawm, nyob ntawm kev kho cua sov ntawm cov hlau stainless 304 dai khaub ncaws kev kho, tej zaum peb yuav ua tau kev kho mob, peb yuav ua tau kev kho mob, peb yuav ua haujlwm kev kho mob raws li cov neeg siv khoom ntawm peb tus kheej. Thiab nyob ntawm seb cov nplaim hluav taws xob tag nrho 304L Reducer Fittings, peb tuaj yeem muab lawv ua kom pom kev zoo, peeled rau glossy, lossis ntxhib rau glossy.

Txhawm rau kom xa cov raj xa dej, nws yog ib qho tsim nyog los tshem cov hose ncaj hauv cov raj xa dej. Thaum siv ntau lub raj xa dej, ntau yam kav dej yuav tsum tau siv. Thaum twg cov raj xa dej siv, lub luj tshib yuav tsum tau siv los hloov qhov loj ntawm cov raj xa dej. Thaum bifurcating, peb-txoj kev xaim cov flange kev sib txuas siv thaum lub raj xa hluav taws xob thiab kev sib txuas txias thiab kev sib tw txias thiab kev sib koom ua ke txias. , Hauv kev sib txuas ntawm ntau cov twj paj nruag, kuj tseem muaj cov txuas txuas thiab ntsaws ntawm cov twj paj nruag theem.
