Anti Corrosion PipelinesPuas yog cov chaw tseem ceeb rau kom muaj kev thauj khoom hauv cov kua dej hauv kev lag luam niaj hnub, siv cov tshuaj lom neeg, hluav taws xob, thiab marine engineering. Nws zoo tiv thaiv nruab nrab corrosion, thiab siv cov txheej txheem corrosion, los yog siv cov ntaub ntawv tiv thaiv corrosion-antioy ntawm lub raj raj ntawm raj. Nws muaj cov ntsiab lus tseem ceeb hauv qab no:
Kev thauj mus los ntawm cov xov xwm muaj kev pheej hmoo siab
Nyob rau hauv cov roj av, roj av, thiab kev lag luam chemical,Los tiv thaiv corrosion pipelinestau siv los thauj cov roj corrosive xws li sulphur-muaj roj thiab roj, muaj zog acids thiab alkalis. Piv txwv li, hauv cov roj thiab roj sib txawv, xov xwm nrog cov ntsiab lus hydrogen sulfide siab yog nquag rau hydrogen emrosion corrosion. Kev siv ntawm Epoxy hmoov txheej lossis 3Pe los tiv thaiv corrosion steel kav tuaj yeem zam lub ntsa loog thiab ib puag ncig cov kuab paug los ntawm kev txi.
Kev ua haujlwm ntev ntawm cov txheej txheem
Galvanized steel kav thiab xis mas corrosion thiab kua thiab cua sov network tuaj yeem tiv thaiv cov kav dej loj los ntawm {}} kav hlau kav rau tshaj 30 xyoo. Sab qab teb mus rau Qaum Teb Dej Deversion tau siv Fusion Bonded Epoxy Coated Steel Kave kom ntseeg tau tias dej zoo thiab kav dej ruaj khov.
Corrosion tsis kam nyob rau hauv marine engineering
Desalination of seawater and water injection pipelines for offshore platforms need to deal with chloride ion corrosion and microbial corrosion. Dual theem stainless pipelines lossis fiberglass composite pipelines tuaj yeem tiv taus hnyav ua pob txha nkoj. Roham Oilfield Project Siv Nickel linas raws cov kav dej, uas nce cov kev pabcuam lub neej ntawm cov roj hauv qab ntawm 40%.
Kev tiv thaiv ib puag ncig thiab them tus nqi kho kom zoo
Piv rau tsoos pipelines, tiv thaiv cov kav dej los tiv thaiv corrosion txo qis los ntawm 70%. Raws li cov ntaub ntawv los ntawm International Anti Corrosion Asses los ntawm Corrosion thoob ntiaj teb yog $ 2.5 trillion thoob ntiaj teb tuaj yeem rov qab ntau dua 30% ntawm kev poob. Nyob rau tib lub sijhawm, nws zam cov kuab paug ntawm av thiab dej tshwm sim los ntawm nruab nrab toastage, uas ua tau raws li cov kev xav tau ntawm kev txhawb nqa kev ruaj khov.
Nrog rau daim ntawv thov ntawm cov thev naus laus zis tshiab xws li nano tsho qhia thiab cov neeg ntse soj xyuas, Los tiv thaiv corrosion pipelinestab tom txhim kho ntawm tag nrho lub neej kev tswj hwm, ua ib qho kev tiv thaiv kab ke tseem ceeb rau kev tiv thaiv kev nyab xeeb thiab kev tiv thaiv ecological.
