Ntev- cov kav dej nyob deb feem ntau yog faus, ntsib lub sijhawm ntev - av corrosion thiab kev puas tsuaj sab nraud. Kev ua tau zoo ntawm cov tshuaj tiv thaiv -corrosion txheej ncaj qha txiav txim siab lub neej kev pabcuam. Nrog nws cov txiaj ntsig zoo hauv cov qauv, kev ua tau zoo, kev tsim kho, thiab tus nqi, 3LPE txheej tau dhau los ua cov khoom siv tseem ceeb los tiv thaiv -corrosion tov rau thoob ntiaj teb cov roj thiab cov kav dej.
I. Peb- Txheej Txheej Txheej Txheem: Lub hauv paus Logic ntawm Synergistic Protection
3LPE kub-melt integrated system: FBE hauv qab txheej 150-300μm (blocks dej thiab oxygen) + nplaum nruab nrab txheej 200-400μm (tiv thaiv delamination) + PE txheej txheej ib txwm qib 2.5-3.7mm / reinforced qib siab tshaj 7 hli. Peb txheej ua hauj lwm ua ke los tsim ib tug tuab barrier, kov yeej cov teeb meem ntawm ib leeg-txheej FBE thiab 2LPE, nrog rau kev tiv thaiv deb tshaj rau ib/ob txheej.
II. Ntev -Lub neej Corrosion Resistance: Sib piv tus tsim lub neej ntawm Trunklines
Cov raj xa dej faus tsim lub neej Ntau dua lossis sib npaug li 30 xyoo. 3LPE tiv taus permeation, acid / alkali / ntsev tsuag, thiab thaiv cov xov xwm corrosive. Kev tiv thaiv zoo heev -cathodic disbondment (65℃/ 48h Tsawg dua lossis sib npaug ntawm 8mm yog tus qauv nruj, tus qauv dav dav Tsawg dua lossis sib npaug li 15mm). Thaum ua ke nrog kev tiv thaiv cathodic, kev puas tsuaj tsis kis. Kev tiv thaiv zoo rau 30-50 xyoo, txuam lub neej ntawm lub cev.
III. Cov cuab yeej siv tshuab zoo heev: Hloov kho rau thaj chaw tsim kho
Kev tsim kho teb yog nquag rau kev sib tsoo thiab extrusion. Sab nrauv PE ntawm 3LPE muaj qhov zoo toughness, cuam tshuam tsis kam Ntau dua lossis sib npaug ntawm 15J (-30 degree), khawb thiab hnav tsis kam, thiab tsis yooj yim puas thaum thauj, nqa, thiab txo qis. Siv tau qhov kub thiab txias -40 ~ 70 degree, qhov kub thiab txias hloov mus rau thaj tsam alpine; high-temperature tej yam kev mob yuav xaiv high-temperature hom.
IV. Lub Hoobkas ruaj khov Prefabrication Zoo: Siab Rau -Site Construction Efficiency
3LPE yog tag nrho ua los ntawm lub Hoobkas automated txheej, tas li kub thiab ceev, uniform thickness, tsis muaj pinholes, npuas, los yog sags, nrog zoo sib xws. Cov kav dej tiav tau raug kuaj xyuas, thickness thiab adhesion kuaj ib qho los ntawm ib qho, tawm hauv lub Hoobkas yam tsis muaj qhov xau. Tsuas yog weld sib koom txheej yog xav tau nyob rau ntawm qhov chaw, tsis muaj tha xim yuav tsum tau, heev shortening lub sij hawm tsim kho thiab txo qhov zoo ntawm qhov chaw.
V. Mature Standard System: Ntiaj teb no lees paub rau Engineering
3LPE tiv thaiv-corrosion muaj kev ua tiav hauv tsev thiab thoob ntiaj teb tus qauv. Cov qauv hauv tsev: GB / T 23257, SY / T 0413; Cov txheej txheem thoob ntiaj teb: ISO 21809-1, DIN 30670. Kev lees paub thoob ntiaj teb hauv kev sib tw roj thiab roj, kev sib cuam tshuam thiab kev lees txais yog kev sib koom ua ke, cov lus qhia tshwj xeeb yog paub tab, ua kom muaj kev tswj hwm zoo thiab kev soj ntsuam cov neeg thib peb.
VI. Tag Nrho Lub Neej Cycle Economic Advantage
3LPE tus nqi pib yuav khoom yog me ntsis siab dua ib zaug - txheej tiv thaiv - corrosion, tab sis qhov zoo tshaj plaws yog qhov tseem ceeb. Ntev- kev tiv thaiv lub neej txo qis tom qab kev saib xyuas thiab hloov zaus, txo qis kev ua haujlwm, txij nkawm, thiab kaw qhov poob; Hoobkas prefabrication shortens lub sij hawm tsim kho thiab paub ntau lawm cov txiaj ntsig ua ntej. Nyob rau hauv ntev - voj voog, ntev - cov kav dej nyob deb, tag nrho lub neej voj voog tus nqi kom zoo dua ntawm 3LPE yog qhov pom tseeb dua.
Kev ua tau zoo ntawm 3LPE txheej hauv cov qauv, kev tiv thaiv corrosion, kev tsim kho, thiab kev lag luam zoo sib xws rau cov kev xav tau ntawm cov kav dej ntev ntev - cov roj thiab cov kav dej. Los ntawm Shaanxi-Beijing Pipeline mus rau Sab Hnub Poob-Tebchaws Gas Pipeline, 3LPE tiv thaiv-corrosion tau txheeb xyuas qhov loj hauv cov kab hauv tsev. Nrog rau cov kav dej tsim los ntawm kev kub siab, txoj kab uas hla loj, thiab qhov ntev, 3LPE yuav nyob twj ywm qhov kev nyiam los tiv thaiv -corrosion tov rau cov kav dej faus.
