Puas yog koj tab tom nrhiav txoj cai 316L stainless hlau yeeb nkab specifications rau koj daim ntawv thov? Rau cov thawj coj thiab cov engineers, qhov no yog ib qho kev sib tw, tshwj xeeb tshaj yog nyob rau hauv kev lag luam xws li kev lag luam tshuaj, khoom siv kho mob, kev ua zaub mov, thiab cov khoom siv hluav taws xob. Kev xaiv cov yeeb nkab tsis raug cai tuaj yeem ua rau tsis yog tsuas yog ua rau lub siab tsis ua haujlwm lossis teeb meem kev teeb tsa, tab sis kuj ua rau tus nqi tsis tsim nyog.
Nyob rau hauv phau ntawv qhia no, peb yuav muab koj nrog ib tug meej thiab meej 316L stainless hlau yeeb nkab specification daim ntawv qhia, piav qhia lub ntsiab tseem ceeb hauv kev xaiv cov khoom, thiab pab koj kom tsis txhob muaj kev yuav khoom yuam kev.
Dab tsi yog cov qauv ntsuas rau SS 316L tubing?
Rau 316L tubing, cov qauv siv feem ntau suav nrog:
ASTM A269: Txuj Specification rau Seamless thiab Welded Austenitic Stainless Steel Tubing rau Kev Pabcuam.
ASTM A213: Muaj feem xyuam rau cov raj rau siab -kub boilers, superheaters, thiab tshav kub exchangers.
ASTM A312: ASTM A312 yog tus qauv specification rau seamless, ncaj-seam welded, thiab hnyav hnyav-ua haujlwm (HCW) austenitic stainless hlau yeeb nkab tsim rau siab - kub thiab kev pabcuam corrosive.

Lus Cim: 1. Tag nrho cov ntaub ntawv yog raws li cov lus qhia tshwj xeeb rau 316L stainless hlau (UNS S31603) uas tau teev tseg hauv ASTM A312 tus qauv, muaj qhov tsawg kawg nkaus lub zog ntawm 275 MPa thiab lub zog tensile ntawm 485 MPa.
2. Qhov hnyav ntawm ib lub 'meter' yog tus nqi kwv yees, suav nrog cov qauv hauv qab no: Qhov hnyav (kg / m)=0.02491 × (Sab nraud - Phab Ntsa Thickness) × Phab Ntsa Thickness.
3. Cov kav dej no tsim nyog siv rau hauv kev ua tshuaj lom neeg, kev tsim khoom hauv hiav txwv, kev ua zaub mov, thiab lwm qhov chaw corrosive.
4. Rau SCH 160 lossis lwm lub sijhawm tshwj xeeb ntawm cov yeeb nkab, thov hu rau peb kom tau txais cov lus qhia tshwj xeeb.
Nyem kom tau 316L SCH 160 Pipe Specification
Dab tsi yog qhov txawv ntawm 316 thiab 316L stainless hlau kav?
Thawj qhov sib txawv ntawm 316 thiab 316L stainless hlau kav yog cov ntsiab lus carbon: 316L (Low carbon) muaj qhov siab tshaj plaws ntawm 0.03% carbon, thaum 316 muaj txog 0.08%. Cov pa roj carbon qis hauv 316L no txo qis carbide nag lossis daus thaum vuam, muab kev tiv thaiv corrosion zoo tshaj hauv cov qauv welded, thaum 316 muaj zog tensile zog me ntsis.
Yam Tseem Ceeb Cov neeg yuav khoom yuav tsum xav txog
1. Sab nrauv thiab phab ntsa Thickness
Ntau tus neeg yuav khoom tsuas yog tsom mus rau sab nraud (OD); Txawm li cas los xij, lub raj lub siab- cov kabmob muaj peev xwm yeej nyob ntawm nws phab ntsa tuab. Piv txwv li, nce phab ntsa thickness los ntawm tsuas yog 1 hli tuaj yeem txhawb kev ua haujlwm siab los ntawm 20% mus rau 40%. Txawm tias nyias- cov hlab ntsa tuaj yeem txo cov nqi, lawv kuj ua rau muaj kev pheej hmoo ua tsis tiav.
2. Daim ntawv thov yuav tsum tau
Thaum tshav kub kub Exchangers: Yuav tsum tau muaj meej Inner Diameter (ID) qhov ntev los xyuas kom meej cov dej ntws zoo thiab du.
Khoom noj khoom haus thiab Pharmaceutical Industries: Yuav tsum tau cov hlab nrog du puab nto (Roughness Ra tsawg dua los yog sib npaug rau 0.8 μm).
Kev lag luam tshuaj: Yuav tsum tau cov raj uas muaj kev tiv thaiv corrosion zoo heev thiab tsim nyog phab ntsa thickness.
3. Cov qauv thiab kev ua raws cai
Nws yog ib qho tsim nyog los xyuas kom meej tias cov tubing xaiv tau ua raws li cov qauv hauv qab no:
ASTM A269 / A213 (Cov qauv rau kev dav dav - lub hom phiaj thiab cov cua kub exchanger tubing)
TS EN 10216-5 (Tebchaws Europe)
Cov khoom lag luam uas tsis ua raws li cov qauv no yuav ua rau muaj qhov tsis sib haum xeeb lossis txawm tias lub neej ua haujlwm luv luv rau cov tubing.
4. Ntev thiab Customization Services
Tus qauv ntev rau tubing yog feem ntau 6 meters; Txawm li cas los xij, ntau qhov haujlwm feem ntau nthuav qhia cov kev xav tau tshwj xeeb:
Precision txiav - mus rau - ntev cov kev pab cuam (nrog rau qhov kam rau ua ± 1 hli)
Coiled tubing rau kev siv tshwj xeeb
Los ntawm kev siv cov kev pabcuam customization, cov khoom pov tseg tsim tawm thaum lub sijhawm teeb tsa thiab kev tsim kho tuaj yeem raug txo los ntawm 10% mus rau 15%.
