Yog tias koj tab tom npaj yuav 316 stainless hlau kav, ib qho ntawm cov lus nug feem ntau yog: Ntau npaum li cas 316 stainless hlau yeeb nkab nqi ib ko taw? Cov lus teb nyob ntawm ntau yam xws li qhov loj, phab ntsa thickness, hom kev tsim, thiab kev lag luam.
Hauv phau ntawv qhia no, peb rhuav tshem tus nqi, kev qhia tshwj xeeb, thiab cov lus qhia tseem ceeb ntawm kev yuav khoom los pab koj ua tus nqi -kev txiav txim zoo.
Xyoo 2026, kev lag luam thoob ntiaj teb stainless hlau txuas ntxiv nthuav tawm tus nqi nruab nrab, feem ntau yog tsav los ntawm kev lag luam tsis hloov pauv ntawm cov ntsiab lus tseem ceeb xws li npib tsib xee (Ni) thiab molybdenum (Mo). Raws li cov ntaub ntawv kev lag luam tsis ntev los no, cov nqi npib tsib xee tseem nyob hauv qhov hloov pauv ntawm $ 16,000 txog $ 20,000 ib metric ton, thaum molybdenum tus nqi- txwv tsis pub khoom noj khoom haus tsis txaus- tau ntsib ib ntus kev sib tw.
Yog li ntawd, tus nqi ib -ko taw ntawm 316 stainless hlau tubing tau dhau los ua kom muaj zog dua. Rau cov haujlwm uas suav nrog loj- ntim khoom lossis ntev- cov ntawv cog lus muab khoom, cov neeg yuav khoom tau hloov pauv lawv txoj kev tsom mus rau tus nqi ruaj khov, kev ntseeg siab ntawm tus neeg muag khoom, thiab tus nqi zoo cuam tshuam nrog kev yuav khoom ntau.
Nruab Nrab Ib -Tus Nqi Ko Taw ntawm 316 Stainless Hlau Tubing
Nyob rau hauv lub ntiaj teb no kev lag luam ib puag ncig tam sim no, tus nqi kwv yees li nram no:
Qhov Loj (1/2 "- 2"): $ 8 - $ 25 ib ko taw
Medium Diameter (2 "- 6"): $ 25 - $ 80 ib ko taw
Loj Loj (6 "- 24"): $ 80 - $ 300+ ib ko taw
Tus nqi tiag tiag yuav txawv nyob ntawm tus nqi ntawm cov khoom siv raw (xws li npib tsib xee thiab molybdenum), cov khoom siv sib txuas, thiab kev txiav txim ntim.
Nyem kom tau txais tus nqi tshiab rau 316 SS yeeb nkab
Vim li cas koj 316 Stainless Hlau Yeeb Nkab Hloov Hloov?
Koj qhov 316 stainless hlau yeeb nkab nqe lus yuav zoo li hloov pauv vim cov nqi ntawm cov khoom siv tsis hloov pauv (tshwj xeeb yog npib tsib xee thiab molybdenum), qhov kev thov nce siab rau qib siab - qib steel, thiab nruj thoob ntiaj teb cov saw hlau ua rau muaj nqi ntxiv. Raws li lub Peb Hlis 2026, 316-series cov nqi tau nce, thiab xav tias yuav nce mus ntxiv vim cov kev lag luam no.
Yuav ua li cas xam 316 Stainless Hlau Yeeb Nkab Nqe Ib Ko Taw?
Hauv kev lag luam steel, tus nqi feem ntau hais los ntawm qhov hnyav (ib phaus lossis ib kilogram). Ua ntej, koj yuav tsum txiav txim siab qhov hnyav ib ko taw rau cov yeeb nkab ntawm cov lus qhia tshwj xeeb.
Stainless Hlau Yeeb Nkab Qhov Ntsuas Qhov Ntsuas (Imperial Units): W=10.69 × (D − t) × t
W: Nyhav, hauv phaus ib ko taw (lb / ft).
D: Outer Diameter (OD), hauv nti.
t: Phab ntsa thickness, hauv nti (piv txwv li, Sch 40S lossis Sch 80S).
Piv txwv xam:
Rau 2-nti Sch 40S 316 yeeb nkab:
Sab nraud txoj kab uas hla (D): 2.375 nti
Phab ntsa Thickness (t): 0.154 nti
Cov txheej txheem suav:
10.69 × (2.375 - 0.154) × 0.154=3.66 lb/ft
Dab tsi cuam tshuam rau tus nqi ntawm 316 stainless hlau kav?
1. Cov khoom siv sib xyaw
316 stainless hlau muaj 2% mus rau 3% molybdenum; thaum qhov no txhim kho nws cov corrosion kuj, nws kuj ua rau tus nqi siab dua piv rau 304 stainless hlau.
2. Yeeb Nkab Dimensions thiab Phab Ntsa Thickness
Qhov ntau dua phab ntsa thickness (piv txwv li, SCH 80 specifications piv rau SCH 40 specifications), qhov tseem ceeb ntawm tus nqi nce.
3. Cov txheej txheem tsim khoom
Tus nqi ntawm 316 seamless kav feem ntau yog 30% mus rau 50% siab dua li cov kav dej welded. Qhov no yog vim lawv qhov tsim nyog nyob rau hauv siab - ib puag ncig siab (xws li Class 300 daim ntawv thov), nrog rau cov txheej txheem tsim khoom ntau dua thiab tus nqi siab dua ntawm cov yeeb nkab billets.
4. Nto tiav
Cov kav dej uas tau dhau los ua polishing lossis kev kho tshwj xeeb saum npoo yuav raug nqi ntau dua li cov txheej txheem kev lag luam - qib nto tiav.
Puas yog 316 stainless hlau yeeb nkab kim dua 304?
Yog lawm, 316 stainless hlau yeeb nkab feem ntau kim dua 304 stainless hlau yeeb nkab, feem ntau raug nqi 10-30% mus rau 50% ntau dua nyob ntawm kev ua lag luam. Cov nqi siab dua no yog vim qhov sib ntxiv ntawm 2-3% molybdenum thiab ntau dua cov ntsiab lus nickel, uas muab kev tiv thaiv corrosion tiv thaiv chlorides thiab marine ib puag ncig.
Ntawm GNEE, peb yog ntau tshaj li cov kav dej xa khoom; peb muab "npaj-rau-siv" piping solutions. Txawm hais tias koj yog lub luag haujlwm rau kev kaw thiab kev saib xyuas, kev cog qoob loo tshuaj lom neeg, lossis siab -txoj haujlwm sab nraud, peb muaj ntau yam ntawm 316 stainless hlau cov khoom ua raws li ASTM A312 / A213 cov qauv.
