1. Cov dej txias txias
Cov dej txias txias yog ib txoj kev siv los tiv thaiv corrosion, feem ntau yog siv los tiv thaiv X52 cov kav dej los ntawm kev corroded thaum lub caij txias. Cov dej txias txias tuaj yeem tsim cov yeeb yaj kiab tiv thaiv kom tsis txhob muaj cov pa oxygen thiab dej los ntawm kev sib cuag nrog cov phab ntsa sab hauv ntawm cov kav dej, yog li ua tiav cov nyhuv tiv thaiv corrosion.
2. Txheej txheej
Cov txheej txheej hauv ob sab phlu yog ib txoj hauv kev los tiv thaiv corrosion uas coated ib txheej ntawm cov khoom tshwj xeeb hauv X52 pipeline. Feem ntau siv cov khoom siv hauv ob sab phlu muaj xws li polyethylene, polyurethane, thiab lwm yam. Cov txheej txheej hauv ob sab phlu tuaj yeem cais tawm sab hauv ntawm cov kav dej los ntawm qhov nruab nrab thiab tiv thaiv qhov tshwm sim ntawm corrosion.
3. Kub-dip galvanizing
Kub-dip galvanizing yog feem ntau siv hlau los tiv thaiv corrosion, feem ntau yog siv los tiv thaiv X52 pipelines los ntawm corroded los ntawm atmospheric ib puag ncig. Kub-dip galvanizing yog muab tso rau hauv X52 pipeline hauv molten zinc los tsim ib txheej tiv thaiv zinc. Zinc muaj kev tiv thaiv corrosion zoo thiab tuaj yeem txuas ntxiv kev pab cuam lub neej ntawm X52 pipeline.
4. Epoxy txheej
Epoxy txheej yog feem ntau siv los tiv thaiv corrosion, feem ntau yog siv los tiv thaiv X52 kav dej los ntawm corroding hauv av. Epoxy txheej tuaj yeem tsim cov txheej txheem tiv thaiv kom tsis txhob muaj dej thiab cov pa oxygen hauv cov av los ntawm kev sib cuag cov kav dej, yog li ua tiav cov nyhuv tiv thaiv corrosion.
5. Cathodic tiv thaiv
Kev tiv thaiv cathode yog ib txoj kev siv hluav taws xob los tiv thaiv corrosion uas feem ntau siv tam sim no rau X52 cov kav dej kom ua rau cov kav dej ntawm lub cathode, yog li tiv thaiv cov hlau corrosion. Kev tiv thaiv Cathodic tuaj yeem txuas ntxiv lub neej kev pab cuam ntawm X52 pipeline mus rau qee yam.
6. Polyurethane ua npuas ncauj rwb thaiv tsev txheej
Polyurethane ua npuas ncauj rwb thaiv tsev txheej yog ib qho kev siv rwb thaiv tsev thiab kev tiv thaiv corrosion, feem ntau yog siv rau X52 pipelines los tiv thaiv condensation thiab condensation nyob rau hauv qis kub ib puag ncig. Polyurethane ua npuas ncauj rwb thaiv tsev txheej tuaj yeem txo qhov kub ntawm qhov sib txawv ntawm cov kav dej kub thiab qhov kub thiab txias, yog li txo qhov tshwm sim ntawm corrosion.
7. Polyethylene txheej txheej
Polyethylene txheej txheej yog feem ntau siv sab nraud los tiv thaiv corrosion, feem ntau yog siv los tiv thaiv X52 pipelines los ntawm corroding hauv av. Polyethylene txheej txheej tuaj yeem tsim cov txheej txheem tiv thaiv kom tsis txhob muaj dej thiab cov pa oxygen hauv cov av los ntawm kev sib cuag cov raj xa dej, yog li ua tiav cov nyhuv tiv thaiv corrosion.
