Kev Xa Khoom: 20-45 hnub
Kev Them Nyiaj: T / T, L / C, thiab lwm yam
Nyob rau hauv cov roj qaub thiab cov roj av ib puag ncig, hydrogen sulfide (h ₂S) raug rau cov khoom tseem ceeb rau cov khoom siv hlau, nrog hydrogen {}) yog ib qho ntawm cov tsis ua kev puas tsuaj loj. HIC tshwm sim thaum hydrogen atoms, tsim los ntawm h ard corrosion, diffuse rau hauv cov hlau matrix thiab suav nrog cov kab ke lossis cov kab ke sab hauv uas muaj kev ncaj ncees. Peb cov lus no - tiv taus cov kev phom sij steel, muab cov cuab yeej siv hluav taws xob tshwj xeeb, muab cov cuab yeej siv ua kom zoo nkauj hauv cov acidic acidic ib puag ncig.

Kev Ntsuas Cov Lus Loj: Post {{-} Kev Tsom xam cov kev tsom xam, nrog cov txiaj ntsig sib ntsib lossis tshaj li kev lag luam:
Tawg nteeb ntev ratio (clr) tsawg dua los yog sib npaug rau 5%
Tawg thickness piv (ctr) tsawg dua lossis sib npaug rau 2%
Nrib pleb rhiab recio (CSR) tsawg dua lossis sib npaug rau 1%
Txawv los ntawm SSC: kev tiv thaiv kev tiv thaiv
Thaum lub sij hawm qaub sij hawm kuj tseem muaj kev cuam tshuam sulfide kev ntxhov siab corrosion (SSC) {{}} peb cov khoom tsom rau ntawm HIC tsis kam. Hic sib txawv ntawm SSC nyob rau hauv tias nws tshwm sim yam tsis tau thov kev ntxhov siab, tshwm sim ntawm hydrogen diffusion thiab tsub zuj zuj. Rau cov ntawv thov uas xav tau kev tiv thaiv no thiab SSC tiv thaiv, peb tau ua cov kev daws teeb meem, tab sis cov phaj ua tau zoo rau cov xwm txheej hauv no yog qhov kev pheej hmoo thawj.
Kev Ntsuas & Raug
Engineering rau HIC Kuj
Qhov tshwjxeeb ua haujlwm ntawm peb lub phaj steel stems los ntawm kev tswj hwm tshwj xeeb thiab cov txheej txheem ntau lawm:
Kev tswj nruj ua rau muaj kev phom sij
Sulphur (s) tsawg dua los yog sib npaug rau 0.001% (10 ppm): Minimizes sulfide suav, uas ua raws li kev pib thawj lub tuam tsev rau HIC.
Phosphorus (p) tsawg dua lossis sib npaug rau 0.010%: Txo cov qoob loo ciam ciam brittleness, txo qis hydrogen traps kev ua tau zoo.
Hydrogen (h) tsawg dua lossis sib npaug rau 2 ppm: Nruj deshydrogenation cov txheej txheem txwv tsis pub dhau hydrogen siab buildup.
Alloy Tsim rau Hydrogen Mitigation
Chromium (CR: 1.0-1.5%): Txhim kho cov nkoj passivation, txo qis cov adsorption thiab tom qab hydrogen ntau tiam.
Molybdenum (MO: 0.2-0.4%): Inhibits hydrogen diffusion los ntawm cov hlau matrix, qeeb tawm cov lus tshaj tawm.
Niobium (NB: 0.02-0.05%): Kho kom tau cov qauv lis cov qauv thiab ruaj khov carbides, txo cov ntxiab hydrogen.
Kev kho cua sov rau microstracation
Txhua daim phiaj yauv mus600-650DEGITING TOMICING(tuav lub sijhawm 3-4 teev) kom daws cov kev ntxhov siab thiab ua kom zoo microstructure, ntxiv txo kev ua tau zoo.
Daim ntawv thov daim ntawv thov: Pov thawj nyob rau hauv cov chaw pw
Nyob rau hauv 180km qaub roj pipeline project nyob rau sab qab teb Asia, ua haujlwm los ntawm kev ua haujlwm ntawm cov yeeb yaj kiab
Tom qab 5 xyoo ntawm kev ua haujlwm tiag tiag, txoj haujlwm tau pom tau zoo tshaj plaws: hauv kev kuaj ultrasonic zoo nkauj, tsis muaj hydrogen {}}) tau kuaj pom; Qhov nruab nrab phab ntsa thickness txo ntawm cov raj dej yog 0.15mm, uas tsuas yog 0.03mm, nyob hauv qab no cov nyiaj uas muaj kev cia siab nyob hauv cov chaw ib puag ncig soob; Ib qho ntxiv, piv nrog cov phiaj xwm siv cov pa hlau, cov nqi txij nkawm tau raug txo los ntawm 35%, thiab cov ntaub ntawv no tau txheeb xyuas los ntawm ib tog neeg kuaj xyuas (FAN-2024-112).
