A387 qib 11 yog dab tsi?

Nyob rau hauv siab -kub thiab siab - siab siv kev lag luam,kev xaiv cov khoom tsis yog kev txiav txim siab them nqi-nws yog kev txiav txim siab txog kev nyab xeeb. Kev xaiv cov phaj hlau tsis raug tuaj yeem ua rau ua tsis tiav ntxov, kev kaw tsis tau npaj tseg, lossis txawm tias muaj kev puas tsuaj loj. Ntawm chromium-molybdenum alloy steels,ASTM A387 Qib 11tau dhau los ua ib qho ntawm cov ntaub ntawv dav dav tshaj plaws rau cov hlab ntsha siab ua haujlwm nyob rau hauv qhov kub siab.

Yog li ntawd,A387 Qib 11 yog dab tsi, thiab vim li cas nws thiaj ntseeg tau thoob plaws lub zog tsim hluav taws xob, petrochemical, thiab kev lag luam ua kom zoo thoob ntiaj teb? Kab lus no muab cov lus piav qhia ua tiav, siv tau los ntawm kev sib xyaw rau cov ntawv thov -pab engineers, EPC cov neeg cog lus, thiab pab pawg neeg yuav khoom txiav txim siab.

A387 Qib 11 yog chromium-molybdenum (Chrome Moly) alloy steel phaj cov ntaub ntawv, txhais los ntawm ASTM tus qauv, siv rau siab - kub thiab siab - kev siv siab xws li cov hlab ntsha siab, boilers, thiab kub exchangers, tshwj xeeb tshaj yog nyob rau hauv cov roj, roj, thiab tshuaj lom neeg kev lag luam, vim nws corrosion kuj zoo heev. Nws muaj kwv yees li 1.25% Chromium (Cr) thiab 0.50% Molybdenum (Mo), nrog rau Chav Kawm 1 thiab Chav Kawm 2 variations, tom kawg yuav tsum tau nruj dua kev kho cua sov thiab cuam tshuam toughness.

Ua tib zoo tswj alloying ntsiab nyob rau hauvA387 Qib 11 steel phajyog lub hauv paus ntawm nws qhov kev ua tau zoo.

Cov tshuaj muaj pes tsawg leeg (kub tsom xam, max %):

• Carbon (C): Tsawg dua lossis sib npaug rau 0.15
• Silicon (Si): 0.50
• Manganese (Mn): 0.30–0.60
• Chromium (Cr): 1.00-1.50
• Molybdenum (Mo): 0.45-0.60
• Phosphorus (P): Tsawg dua lossis sib npaug rau 0.035
• Sulfur (S): Tsawg dua lossis sib npaug rau 0.035

CovCr-Mo alloy systemtxhim kho oxidation tsis kam ntawm qhov kub siab thiab txhim khu kev tiv thaiv hydrogen nres- tseem ceeb rau kev ua kom zoo thiab kev pabcuam hydrogen.

A387 Qib 11 siab lub nkoj steelmuab ib tug sib npaug sib xyaw ntawm lub zog, ductility, thiab toughness.

Cov yam ntxwv mechanical zog:

• Yield zog: Ntau dua los yog sib npaug rau 310 MPa
• Tensile zog: 415-585 MPa
• Elongation: Ntau dua lossis sib npaug li 18%
• Kev ntsuam xyuas qhov cuam tshuam: Raws li tau teev tseg (feem ntau yuav tsum muaj rau qis-kev pabcuam kub)

Cov khoom no tso cai rau cov hlautuav cov txheej txheem kev ncaj ncees nyob rau hauv ntev -lub sij hawm thermal stress, ua rau nws haum rau kev ua haujlwm tsis tu ncua ib puag ncig.

Los ntawm qhov kev xav ntawm fabrication,A387 Qib 11 steel phajyog zoo- haum rau vuam, muab cov txheej txheem kom raug raws li.

Cov ntsiab lus tseem ceeb welding:

• Preheating yog pom zoo (feem ntau 150-250 degree)
• Tsawg- cov khoom siv hydrogen welding (piv txwv li, E8018-B2)
• Tswj cua sov input
• Tom qab-weld heat treatment (PWHT) feem ntau yuav tsum tau

Thaum welded raug, A387 Gr.11 nthuav tawmkuj zoo heev rau weld-txog kev tawgthiab tuav lub zog hauv tshav kub- thaj chaw cuam tshuam (HAZ).

GNEE Steel muabvuam kev taw qhia thiab kev txhawb nqalos xyuas kom meej fabrication du thiab ua raws li qhov project specifications.
