ASTM B690yog tus qauv txheem tshwj xeeb rau * "hlau -} chromium alsoys (tsis muaj n08367) Seamless yeeb nkab thiab raj". Nws txhais tau cov tshuaj, neeg kho tshuab, thiab qhov chaw nyob sab nraud rau ntawm cov khoom siv seamless tubular cov khoom ua los ntawm cov tshwj xeeb no "Super-}}}}}}}}}}}}}}}}}}}}}}}}}}}} txoj kab mob".
Cov khoom no feem ntau siv nyob rau hauv kev siv cov hlau sib txawv uas cov qauv stainless hlau zoo li 304/316 yuav nrawm.

Thawj qhov sib txawv nyob hauv cov ntsiab lus carbon, uas cuam tshuam rau lawv cov haum rau vuam.
Unrical N08366: Qib qib nrog qhov siab tshaj plaws cov ntsiab lus carbon ntau ntawm 0.030%. Haum rau feem ntau cov ntawv thov.
Unrical N08367: "Tsawg {{- Carbon" qib nrog cov ntsiab lus carbon ntau kawg ntawm0.020%Cov. Cov qib no yog qhov zoo dua rau cov ntawv thov welded vim tias cov ntsiab lus txo cov roj carbium txo qis hauv qhov cua sov (Haz), yog li khaws cia corrosion tawm tsam tom qab vuam.

KhoomCov Kev Siv Cov Ntawv Siv
Seamless cov yeeb nkab thiab raj ua rau Astm B690 yog siv nyob rau hauv ib puag ncig corrosive uas tsis tshua muaj:
Kev Lag Luam Tshuaj Kev Lag Luam:Cov hlab, kev sib pauv cua sov, thiab cov piping kov corrosive tshuaj.
Roj & Roj:Downhole thiab cov khoom siv saum npoo av, tshwj xeeb tshaj yog hauv kev pab qaub (h {-}}}} muaj) thiab ntug dej hiav txwv.
Tubrog Ntxhais Tub Rog & Dej Hiav Txwv:Dej khov dej txias, kev hloov cua sov, Desalination cog cov khoom sib xyaw.
Vienution Control:Flue Gas Desulfurization (FGD) lub tshuab, hloov pauv.
Kws Tshuaj & Ua Zaub Mov Noj:Cov khoom siv uas yuav tsum muaj kev coj dawb huv siab thiab kev tawm tsam kom tu cov neeg sawv cev.
Pulp & Daim Ntawv Kev Lag Luam:Cov tshuaj ua kom dawb thiab cov chiv ua haus tshuaj lom neeg.
KhoomTseem Ceeb Zoo
Kuj: Chloride Kev ntxhov siab corrosion cracking (cl - scc):Lawv cov ntsiab lus nickel siab ua rau lawv loj dua qub rau 300 {{series}}} s chlorides, xws li dej hiav txwv, tshuaj dawb, thiab ntsev.
Tshwj xeeb pitting & Crevice Corrosion Kuj:Qhov no yog qhov tseem ceeb los ntawmPitting tiv thaiv tus lej sib npaug (pren).
Pren =% cr + 3.3 (% mo)+ 16 (% n)
Rau unic tsis ntseeg n08366 / 7: pren 21 + (3.3 × 6.22) {{8} {8}~45
Tus Pren no yog siab dua 316 stainless (pren ~ 26) thiab txawm tias super duplexs zoo li 2507 (pren ~ 42-45).
Zoo tshaj Franosion Kuj:Ua kom tsis txhob muaj ntau hom acids, suav nrog cov sulfuric, phosphoric, thiab cov organic acids.
Lub zog siab:Kev sib xyaw ntawm nitrogen ntxiv dag zog thiab cov ntsiab lus zoo muab rau nws ntau dua cov txiaj ntsig thiab lub zog tensile dua cov qauv tshuaj tiv thaiv cov hlau.
Cim npe nrov: ASTM B690 unic n08366 Seamless Yeeb Nkab, Tuam Tshoj ASTM B690 Tsis Yog N08367 Seamless Yeeb Nkab Cov Chaw Tsim Tshuaj, Chaw muag khoom, Hoobkas
