Raws li tus neeg muag khoom ntawm ASME- tau ntawv pov thawj SA 387 Gr. 22 Cl. 2 daim hlau thiab kev caitube plhaub kub exchangers.

SA 387 GR. 22 CL. 2 Phaj yog dab tsi?

Alloy steel SA 387 GR. 22 CL 2 yog cov hlau tshwj xeeb & tsim siv cov qauv sib txawv thiab cov qauv tshwj xeeb. Hlau ua rau nws tuaj yeem tsim cov khoom siv rau hauv ntau yam khoom kawg & cov khoom kawg suav nrog cov phaj rau cov boilers, welded boilers, thiab cov hlab ntsha siab. CovSA 387 GR.22 CL.2 Phajmuaj chromium concentration ntawm 2.25% thiab molybdenum cov ntsiab lus ntawm 1%. Cov chromium thiab molybdenum steel daim hlau no ua haujlwm tau zoo ntawm ntau qhov kub thiab muaj kev ua tau zoo tshaj plaws.

Chemical Composition (Cast Analysis, %)

Lub 2.25Cr-1Mo alloy muaj pes tsawg leeg yog lub hauv paus ntawm nws qhov kev ua tau zoo heev. Hauv qab no yog cov kev txwv nruj rau ASME SA-387 / SA-387M:

Mechanical Properties (yam tsawg kawg nkaus)

Tom qab Q&T kev kho cua sov, SA 387 Gr. 22 Cl. 2 yuav tsum ua tau raws li cov qauv hauv qab no:

Daim ntawv thov ntawm SA 387 GR. 22 CL. 2 Phaj

Nws muaj cov tshuaj lom neeg zoo heev thiab cov khoom siv kho tshuab & muab ntau dua txhua yam lub zog, yielding zog, thiab tensile lub zog. Qhov tshwj xeeb thiab muaj txiaj ntsig zoo uas SA 387 GR.22 CL.2 PLATES muab ua rau nws xaiv zoo rau ntau yam kev siv thiab kev siv hauv kev lag luam.

Ntxiv chromium rau cov hlau ua kom nws cov oxidation tsis kam ntawm qhov kub siab. Cov phaj no muaj kev tiv thaiv zoo rau pitting corrosion thiab crevice stress cracking corrosion.

Qhov no muab cov cua sov ua kom muaj zog thiab ua haujlwm zoo tiv thaiv cov tshuaj corrosive los ntawm cov hlau yaj, uas ua rau nws muaj kev xaiv zoo heev rau cov roj ib puag ncig & weldability kuj zoo.

Nws ua tau zoo nyob rau hauv qhov kub txog li 600 Deg C thiab yog siv los thauj cov kua kub.

Cov khoom muaj peev xwm tiv taus corrosion ua rau nws sib nrug los ntawm lwm hom carbon hlau. Nws feem ntau yog siv rau hauv cov hlab ntsha thiab cov khoom siv hluav taws xob sib hloov thiab yog qhov kev xaiv zoo tshaj plaws rau qhov chaw qaub roj.

Xaus

SA 387 Gr. 22 Cl. 2 daim hlau yog qhov kev xaiv zoo tshaj plaws rau kev kub siab heev - kub, siab - siab, thiab corrosive industrial puag ncig. Lawv cov 2.25Cr-1Mo muaj pes tsawg leeg, Q&T kev kho cua sov, thiab nruj ASME ntawv pov thawj xa cov kev ntseeg siab tsis sib haum rau cov khoom siv tseem ceeb xws li lub plhaub plhaub cua kub exchangers, petrochemical reactors, thiab fais fab nroj tsuag boilers.

Los ntawm kev xaiv SA 387 Gr. 22 Cl. 2, koj txo lub sijhawm poob qis, txo cov nqi kho, thiab ua kom muaj kev nyab xeeb ntawm kev ua haujlwm-txawm tias nyob rau hauv qhov hnyav tshaj plaws. Rau kev txhawb nqa tus kheej, kev cai hais lus, lossis kom paub meej cov khoom tsim nyog rau koj qhov project, hu rau GNEE hnub no.

FAQs Txog SA 387 Gr. 22 Cl. 2 Phaj

Q1: Qhov txawv ntawm SA 387 Gr. 22 Cl. 1 thiab Cl. 2 yog dab tsi?

A: Cl. 2 raug quenching + tempering (Q&T) kom muaj zog tawm los ntau dua (345 MPa vs. Cl. 1's 275 MPa), ua rau nws haum rau siab - cov khoom siv siab heev. Cl. 1 siv normalizing + tempering thiab yog rau nruab nrab -kev siv siab.

Q2: Puas yog SA 387 Gr. 22 Cl. 2 tuaj yeem siv rau hauv kev pabcuam qaub?

A: Yog-thaum kuaj rau NACE MR0175/ISO 15156, nws tiv taus sulfide kev nyuaj siab corrosion cracking (SSCC) hauv H₂S- muaj ib puag ncig.

Q3: Qhov siab tshaj plaws thickness ntawm SA 387 Gr. 22 Cl. 2 daim hlau yog dab tsi?

A: GNEE khoom siv txog li 300mm thickness rau cov hlab ntsha loj thiab cov reactors.

Q4: SA 387 Gr . 22 piv rau 316 stainless hlau li cas?

A: 316 stainless hlau muaj kev tiv thaiv corrosion zoo dua rau cov kua qaub / chlorides tab sis qis qis zog ntawm 600+℃. SA 387 Gr. 22 Cl. 2 yog tus nqi ntau dua - siv tau rau siab - kub / siab- cov ntawv siv siab yam tsis muaj tshuaj lom neeg corrosion.
