3PE anti-corrosion steel pipe imatanthauza chitoliro chachitsulo cha PE chokhala ndi zigawo zitatu za anti-corrosion. 3pe odana ndi dzimbiri zitsulo chitoliro ndi mtundu wa zitsulo chitoliro ndi katundu ndi zabwino odana ndi dzimbiri ndipo chimagwiritsidwa ntchito masiku ano. Ndi zinthu ziti zotsutsana ndi dzimbiri zomwe mapangidwe a 3pe anti-corrosion steel mapaipi amakhala? Ndi mfundo ziti zomwe 3pe anti-corrosion zitsulo mapaipi angatetezere dzimbiri?

1. Anti-dzimbiri mapaipi zitsulo nthawi zambiri amagwiritsa ntchito njira ziwiri zazikulu: ❖ kuyanika akunja ndi cathodic chitetezo.

2. Ngakhale kuti pamwamba pa mapaipi achitsulo amaphimbidwa ndi zokutira, kutayikira pang'ono kumayambitsa chiwopsezo chosayerekezeka, kapena mabowo kapena ming'alu. Chifukwa chake, polimbana ndi dzimbiri mapaipi achitsulo, makina opaka, ndi chitetezo cha cathodic nthawi zambiri amagwiritsidwa ntchito limodzi kuti akwaniritse 100% kuti apewe zotsatira zosayembekezereka m'tsogolomu.

3. Cathodic chitetezo ntchito odana dzimbiri mapaipi zitsulo lagawidwa mu nsembe cathodic chitetezo ndi chidwi panopa cathodic chitetezo.

4. Cholinga cha ❖ kuyanika kwa 3pe odana ndi dzimbiri zitsulo payipi odana ndi dzimbiri ndi kupanga mosalekeza chophimba wosanjikiza wa insulating zakuthupi mwachindunji insulate zitsulo ku electrolyte kukhudzana mwachindunji kuti zolondola electrolytic anachita sizingachitike.

5. Mfundo za discontinuity panthawi yoyika zokutira zimatchedwa kutayikira. Amayamba makamaka chifukwa cha zokutira, zoyendetsa, kapena njira zoyika. Zitha kuchitikanso chifukwa chokutira kukalamba, kupsinjika kwa nthaka, kapena kuyenda kwa mapaipi achitsulo m'nthaka. Kulephera kuzindikira zowonongeka zomwe zachitika ndi anthu ena mwachangu.

6. Mfundo ya chidwi panopa cathodic chitetezo: Pogwiritsa ntchito matalikidwe panopa kwa zitsulo zoteteza, kudzera cathodic polarization, pamene kuthekera kwa mfundo zonse cathode kufika lotseguka dera kuthekera kwa yogwira kwambiri anode mfundo, dzimbiri pa dongosolo adzasiya.

7. Zigawo za chitetezo chamakono cha cathodic: rectifier ndi potentiostat

8. Rectifier: Amasintha ma alternating current kukhala olunjika.

9. 3PE anti-corrosion steel pipe a> Potentiometer: chida chamagetsi chomwe chingathe kulamulira mphamvu zonse zazitsulo zazitsulo.
