Anti corrosion thiab thermal rwb thaiv tsev steel yeeb nkab chaw tsim tshuaj paus
High kub prefabricated ncaj qha faus rwb thaiv tsev yeeb nkab yog ib hom ncaj qha faus prefabricated rwb thaiv tsev yeeb nkab nrog zoo rwb thaiv tsev kev ua tau zoo, kev ruaj ntseg thiab kev ntseeg siab thiab tsawg project nqi. Nws zoo daws cov teeb meem ntawm thermal rwb thaiv tsev, zawv zawg lubrication thiab waterproof ntawm cov yeeb nkab kawg ntawm prefabricated ncaj qha faus thermal rwb thaiv tsev yeeb nkab rau kub kub kis tau tus mob ntawm 130 ℃ - 600 ℃ hauv nroog central cua sov. Kub kub prefabricated ncaj qha faus rwb thaiv tsev yeeb nkab tsis yog tsuas yog muaj cov thev naus laus zis thiab kev ua haujlwm tsis zoo los ntawm cov tsoos trench thiab overhead pipeline, tab sis kuj muaj txiaj ntsig zoo rau kev sib raug zoo thiab kev lag luam. Nws kuj yog ib qho kev ntsuas muaj zog rau cua sov thiab txuag hluav taws xob. Kub kub prefabricated ncaj qha faus rwb thaiv tsev yeeb nkab adopts ncaj qha faus cua sov pipeline technology, uas cim hais tias txoj kev loj hlob ntawm cua sov pipeline technology nyob rau hauv Tuam Tshoj tau nkag mus rau ib tug tshiab pib taw tes.?
Lub thermal rwb thaiv tsev yeeb nkab yog tsim los ntawm steel yeeb nkab, FRP puab sheath thiab FRP plhaub, uas yog yus muaj los ntawm nws kuj muaj xws li kub resistant thermal rwb thaiv tsev txheej, lubricating txheej thiab elastic foob. Cov qauv siv hluav taws xob tau zoo daws cov teeb meem ntawm thermal rwb thaiv tsev, zawv zawg lubrication thiab dej tsis zoo ntawm cov yeeb nkab uas muaj qhov kawg ntawm lub prefabricated ncaj qha faus thermal rwb thaiv tsev yeeb nkab rau qhov kub thiab txias ntawm 130 ℃ - 600 ℃ hauv nroog nruab nrab cua sov.
Kub kub prefabricated ncaj qha faus rwb thaiv tsev yeeb nkab yog tsim los ntawm plaub qhov chaw.
(1). Ua hauj lwm steel yeeb nkab: raws li cov kev cai ntawm conveying nruab nrab, seamless steel yeeb nkab, ob-sided submerged arc kauv welded steel yeeb nkab yog saws feem.
(2). rwb thaiv tsev txheej: nruj polyurethane ua npuas ncauj.
(3). Lub plhaub tiv thaiv: siab ceev polyethylene lossis FRP.
(4). Cov kab hluav taws xob hluav taws xob: thaum tsim hluav taws xob kub prefabricated ncaj qha faus cov yeeb nkab rwb thaiv tsev, lub tswb nrov yog faus rau hauv txheej rwb thaiv tsev ze ntawm cov yeeb nkab steel. Thaum muaj qhov xau tshwm sim nyob rau hauv qhov chaw ntawm cov yeeb nkab, lub tswb tuaj yeem muab rau ntawm qhov ntsuas tshwj xeeb los ntawm kev ua haujlwm ntawm lub tswb, thiab qhov tseeb ntawm txoj haujlwm thiab qib ntawm cov dej xau tuaj yeem tshwm sim, thiaj li qhia rau cov neeg ua haujlwm saib xyuas kom pom zoo xau cov yeeb nkab ntu sai, Xyuas kom muaj kev nyab xeeb ntawm cov khoom siv hluav taws xob.
Kub kub prefabricated ncaj qha faus rwb thaiv tsev yeeb nkab - qhov zoo thiab cov yam ntxwv
1. Txo tus nqi ntawm qhov project.
Raws li kev suav ntawm cov tuam tsev muaj feem cuam tshuam, ob chav yeeb nkab cua sov kav feem ntau tuaj yeem txo qhov project nqi li ntawm 25% (siv FRP raws li txheej tiv thaiv) thiab 10% (siv high-density polyethylene li txheej tiv thaiv).
2. Tsawg kub poob thiab txuag hluav taws xob.
Insulated steel yeeb nkab yog ib qho tseem ceeb uas cuam tshuam rau kev txuag hluav taws xob. Txoj kev loj hlob thiab kev siv cov yeeb nkab steel insulated tau nyiam ntau dua thiab ntau dua thoob plaws ntiaj teb. Tom qab xyoo 1970, cov teb chaws txawv teb chaws feem ntau xyuam xim rau kev tsim thiab siv cov thermal rwb thaiv tsev steel yeeb nkab, thiab siv zog ua kom txo tau lub zog noj, thiaj li txo cov pa phem ib puag ncig thiab cov nyhuv tsev cog khoom. Kev lag luam thermal rwb thaiv tsev txawv teb chaws muaj keeb kwm ntev, thiab cov ntaub ntawv thermal rwb thaiv tsev tshiab tau tshwm sim tas li. Ua ntej xyoo 1980, kev txhim kho ntawm thermal rwb thaiv tsev steel yeeb nkab hauv Suav teb tau qeeb heev. Ob peb thermal rwb thaiv tsev nroj tsuag tsuas tuaj yeem tsim ib qho me me ntawm cov av ncaj qha faus thermal rwb thaiv tsev steel yeeb nkab. Txawm li cas los xij, tom qab ntau tshaj 30 xyoo ntawm kev siv zog, tshwj xeeb tshaj yog tom qab ze li ntawm 10 xyoo ntawm kev loj hlob sai, ntau cov khoom tau siv ntau thiab ntau dua los ntawm kos, los ntawm ib leeg mus rau ntau haiv neeg, los ntawm qis mus rau qhov zoo. Cov khoom siv polyurethane yog cov khoom siv thermal rwb thaiv tsev ntau tshaj plaws hauv ntiaj teb. Rigid polyurethane muaj ntau yam zoo heev thiab yog dav siv nyob rau hauv tshav kub rwb thaiv tsev nyob rau hauv cov teb chaws Europe thiab America. Txog 49% ntawm cov ntaub ntawv rwb thaiv tsev thermal hauv cov teb chaws tsim kho xws li Europe thiab Tebchaws Meskas yog cov ntaub ntawv polyurethane, thaum nyob hauv Suav teb, qhov kev faib ua feem tsawg dua 20%. Yog li ntawd, polyurethane insulated steel yeeb nkab tseem muaj qhov chaw loj hlob hauv Suav teb.
1. Cov yeeb nkab tiv thaiv sab nraud: tiv thaiv txheej txheej rwb thaiv tsev los ntawm kev yaig hauv av, txhawb nqa cov yeeb nkab ua haujlwm thiab tuaj yeem dais ib qho kev thauj khoom sab nraud kom ntseeg tau tias kev ua haujlwm zoo ntawm cov yeeb nkab ua haujlwm.
2. Anti corrosion txheej: tiv thaiv cov yeeb nkab steel sab nraud los ntawm cov khoom siv corrosive thiab ua kom lub neej ntev ntawm cov yeeb nkab steel.
3. Drag txo txheej: xyuas kom muaj kev ywj pheej ntawm thermal expansion thiab txias contraction ntawm kev ua haujlwm steel yeeb nkab.
4, polyurethane ua npuas ncauj txheej: xyuas kom qhov kub thiab txias ntawm qhov nruab nrab, thiab xyuas kom meej qhov chaw ntawm lub raj sab nraud yog khaws cia ntawm chav tsev kub.
5. Barrier thiab reflector: xyuas kom meej tias cov khoom ua npuas ncauj tsis nkag mus rau hauv inorganic nyuaj thiab kub-resistant txheej. Reflect ib feem ntawm lub tshav kub ntawm lub siab kub resistant txheej.
6. Ua hauj lwm steel yeeb nkab: xyuas kom meej lub cev ntws ntawm conveying nruab nrab.
7. Inorganic nyuaj rwb thaiv tsev txheej: kub tsis kam, xyuas kom meej qhov kub thiab txias ntawm cov organic rwb thaiv tsev txheej thiab xyuas kom meej tias cov npuas dej tsis carbonized.
