CRA Coated thiab Lined Pipe Application
CRA coated thiab lined yeeb nkab feem ntau yog siv nyob rau hauv kev lag luam roj av rau kev ua hauj lwm tshwj xeeb xws li corrosion los yog kub kub ib puag ncig. Hauv onshore thiab offshore pipeline systems, cov dej thauj khoom feem ntau muaj cov ntsiab lus siab ntawm S, Hâ'S thiab CO'. Thaum cov txiaj ntsig no ncav cuag qee cov ntsiab lus, lawv tsim cov kev txhim kho tseem ceeb hauv cov pa roj carbon thiab carbon-manganese steel kav, xws li API 5L thiab ASTM A106 kav. Hauv qhov no, CRA coated thiab lined yeeb nkab yog siv.
CRA Lined Pipe vs. CRA Lined Pipe: Lub luag haujlwm ntawm cov qauv thiab Corrosion
CRA clad yeeb nkab siv lub metallurgically bonded corrosion resistant alloy txheej uas koom nrog load bearing, ua rau nws haum rau siab dua thiab kub kev pab cuam. CRA lined yeeb nkab yog ua raws li tus neeg kho tshuab lossis hydraulically nthuav dav liner uas muab kev tiv thaiv corrosion thaum cov pa roj carbon steel yeeb nkab txhawb nqa cov qauv thauj khoom. Kev xaiv ntawm coated thiab lined yeeb nkab yog nyob ntawm kev khiav hauj lwm siab, thermal cycling, qhov hnyav ntawm corrosion, thiab teb vuam yuav tsum.
Qhov zoo ntawm CRA yeeb nkab
Kev sib xyaw ua ke ntawm cov khoom siv CRA nrog cov khoom siv carbon steel yog qhov ua tau zoo ntawm ob qho tib si rau cov neeg kho tshuab tsis kam (tensile thiab creep) thiab ua haujlwm zoo tiv thaiv corrosion. Txawm hais tias vim yog cov yam ntxwv ntawm cov yeeb nkab lossis kev txuag nyiaj txiag, coated thiab lined yeeb nkab yog qhov kev xaiv zoo tshaj plaws.
Rau kev tsim cov txheej txheem ntawm CRA coated lossis lined yeeb nkab, muaj ntau txoj hauv kev los koom nrog CRA txheej ntawm cov yeeb nkab steel:
CRA lined yeeb nkab nrog txhua yam sib koom ua ke: nrog txhua yam quab yuam los yog nrog dej siab; CRA lined yeeb nkab nrog metallurgical sib koom ua ke: lub zog tawg yog siv los ua kab sib txuas nrog cov phaj hlau; CRA-coated yeeb nkab los ntawm welding overlay: vuam electrode (stainless hlau los yog alloy) yog siv los tso ib tug tej thickness ntawm lub puab nto ntawm cov yeeb nkab.
Ntawm cov hom no, kev sib koom ua tau zoo tshaj plaws yog ua tiav nrog cov txheej txheem vuam, tab sis tus nqi kuj yog qhov siab tshaj plaws, vim tias cov txheej txheem vuam qeeb heev.
Coated yeeb nkab manufacturing txheej txheem
Lined yeeb nkab manufacturing revolves nyob ib ncig ntawm tsim ib tug txhim khu kev qha daim ntawv cog lus ntawm CRA thiab carbon hlau los ntawm metallurgical txoj kev, yog li cov txheej txheem kev xaiv yog txiav txim los ntawm qhov hnyav ntawm corrosion nyob rau hauv kev pab cuam, CRA qib yuav tsum tau, thiab qhov npaum li cas ntawm kev txais ntawm tau txais. Common lined pipe manufacturing kev xaiv muaj xws li:
- CRA clad yeeb nkab los ntawm kev sib koom ua ke†"Kev sib txuas ua ke siv cov hluav taws xob hluav taws xob tswj tau los tsim cov khoom siv hlau sib txuas ntawm CRA phaj thiab cov pa roj carbon steel rov qab phaj.Cov phaj sib txuas tau txheeb xyuas cov ntaub ntawv tus kheej, daim ntawv cog lus ncaj ncees, txheej tuab thiab qhov chaw ua ntej ua haujlwm ntxiv.
- CRA-coated yeeb nkab los ntawm welding overlay—Weld overlay deposits 316L, Alloy 625 los yog lwm yam CRA teev ncaj qha mus rau lub npaj carbon steel nto.Welding tsis yog tswj kom tsis txhob dilution thiab tswj qhov yuav tsum tau alloy chemistry, overlay thickness thiab nto zoo.
- Plate to Pipe Route (CRA Clad Plate formed into Pipe)†"CRA bonded los yog laminated phaj yog ntug machined, chamfered thiab yeeb nkab tsim los ntawm JCOE, UOE los yog lwm yam kev pom zoo txheej txheem.Lub longitudinal seam yog welded thiab tau tshaj CRA weld hlau yog siv rau sab hauv seam thaum kho corrosion kuj yuav tsum tau.
- Kev tsim cov yeeb nkab nrog mechanical hauv ob sab phlu†"Mechanically lined yeeb nkab siv ib tug nyias tsim CRA liner tso rau hauv ib tug carbon steel txhawb cov yeeb nkab.Hydroforming los yog mechanical expansion raws tag nrho ntev presses lub liner nrees tiv thaiv cov yeeb nkab phab ntsa, ua raws li los ntawm qhov kawg trimming, beveling, thiab tsim nyog xov ntawm liner xaus.
Inconel Alloy 625 / Alloy 625 Liner / CRA 625 Weld Overlay - Nrov CRA yeeb nkab
Inconel 625 alloy yog ib qho deformable, uas tsis yog-sib nqus, corrosion thiab oxidation resistant, Ni-Cr raws li, khoom hardened superalloy. Nickel Alloy 625 yog npib tsib xee-chromium-molybdenum-columbium alloy, nrog cov ntsiab lus tsawg kawg nkaus nickel ntawm 58%, kuj hu ua Inconel 625 lossis UNS N06625. Lwm cov ntsiab lus tshuaj: chromium 20% mus rau 23%, columbium + tantalum 3.15% mus rau 4.15%, molybdenum 8.0% mus rau 10.0%, cobalt tso cai rau 1.0% max. Yog tias txiav txim siab, hlau 5.0% max.
Inconel 625 yog qhov tsis tshua muaj neeg tiv taus rau ntau qhov chaw hnyav hnyav, nrog rau kev kub ntxhov xws li oxidation thiab carburization, nrog rau corrosion. Ua tsaug rau cov kev daws teeb meem ntawm refractory Co thiab Mo hauv nickel-chromium matrix, 625 nthuav tawm qhov kub thiab txias zog thiab tawv, los ntawm qhov kub qis mus txog 2000 ° F (1093 º degree).
Siv cov txheej txheem weld overlay txheej txheej rau txheej Inconel alloy 625 lossis alloy 825 nyob rau sab hauv ntawm cov pa roj carbon steel yeeb nkab tau yog ib qho kev xaiv nrov: nws tsis tsuas yog daws qhov teeb meem ntawm corrosion kuj hloov mus rau qhov sib txawv hnyav, tab sis kuj muab kev ua haujlwm siab nrog kev txuag nyiaj ntau hauv cov nqi.
Lined yeeb nkab manufacturing txoj kev
Rau cov yeeb nkab kab, kev tsim khoom yog ua los ntawm kev sib koom ua ke ntawm cov yeeb nkab carbon steel. (Cov yeeb nkab CRA sab hauv yog muab tso rau txuas nrog cov yeeb nkab C-Mn sab nraud los ntawm cov txheej txheem siv tshuab).
Cov no yog cov kev xaiv rau kev tsim CRA kab yeeb nkab:
