Lipeipi tsa tšepe tse thibelang ho bola li phetha karolo ea bohlokoa le e fapaneng bophelong ba batho ba letsatsi le letsatsi. Liphaephe tsa tšepe tse thibelang ho bola ka kakaretso li bua ka tšebeliso ea mekhoa e khethehileng ea ho phekola liphaephe tse tloaelehileng tsa tšepe (tse kang liphaephe tse se nang mokoloko, lipeipi tse cheselitsoeng), e le hore liphaephe tsa tšepe li be le lintho tse itseng tse thibelang ho bola. Bokhoni ba ho senya hangata bo sebelisetsoa ho thibela metsi, ho thibela mafome, anti-acid le alkali, anti-oxidation le litšobotsi tse ling. Ka kakaretso, peipi ea tšepe ea PE e thibelang kutu e bua ka phala ea tšepe ea polyethylene e thibelang kutu, e leng sengoloa sa tubular se sebetsoang ke mahlale a tsoetseng pele le theknoloji. Lipeipi tsa tšepe tsa PE tse thibelang kutu li sebelisoa haholo oli, khase ea tlhaho, khase ea toropo, phepelo ea metsi a toropo, liphaephe tsa seretse sa metsi a mashala, jj.

Mehato e lumellanang e khahlanong le kutu e ka boela ea etsoa maboteng a ka hare le a ka ntle a liphaephe tsa tšepe ho latela litlhoko tse fapaneng. Tse tloaelehileng ke lipeipi tsa tšepe tsa epoxy coal tar pitch anti-corrosion, polyurethane coating anti-corrosion, seretse sa samente se thibelang kutu leboteng le ka hare la lipeipi tsa tšepe tse thibelang kutu, joalo-joalo. Makala a boenjiniere libakeng tse thata.

Pipe ea tšepe ea anti-corrosion e bolela liphaephe tsa tšepe tse sebetsitsoeng ke theknoloji e thibelang ho bola, e ka thibelang kapa ea liehisa ts'ebetso ea ho senya e bakoang ke lik'hemik'hale kapa tsa electrochemical nakong ea lipalangoang le tšebeliso. Ho ea ka lintlha tsa lipalo-palo tsa naha ea rona, tahlehelo e tobileng ea moruo ea ho bola ha lipeipi tsa tšepe tsa malapeng e feta li-yuan tse limilione tse likete tse 280 selemo se seng le se seng, 'me tahlehelo ea selemo le selemo ea lefats'e ka lebaka la ho bola ha lipeipi tsa tšepe e holimo ho liranta tse limilione tse likete tse 500. Liphaephe tsa tšepe tse thibelang ho bola li ka thibela kapa tsa fokotsa ho bola ka katleho, tsa lelefatsa bophelo ba tšebeletso ea liphaephe tsa tšepe, 'me tsa fokotsa litšenyehelo tsa ts'ebetso ea liphaephe tsa tšepe. Litšobotsi tsa lipeipi tsa tšepe tse thibelang kutu ke ho hanyetsa kutu, ha ho na ho lutla, ho tiea ho hoholo, ho tenyetseha ha maemo, ho hanyetsa mengopo, le ho hanyetsa phetiso e potlakileng ea crack. Ho e 'ngoe, bophelo ba ts'ebeletso ea liphaephe tsa tšepe tse thibelang kutu bo boholo ho feta kapa bo lekana le Tlas'a tikoloho ea likhato tse 60 tsa Celsius, e ka ba le nako ea bophelo ea lilemo tse fetang 50.

Ntle le ho ntlafatsa bophelo ba ts'ebeletso ea liphaephe tsa tšepe ka anti-corrosion, e boetse e bonahatsoa ka lintlha tse latelang:

1. Ho kopanya matla a mochine oa pipe ea tšepe le ho hanyetsa ho bola ha polasetiki.
2. Lerako le ka ntle la lerako le fetang 2.5mm, le sa tsitsang le ho thibela maqhubu.
3. Coefficient ea likhohlano ea lerako le ka hare ke e nyenyane, 0.0081-0.091, e fokotsang tšebeliso ea matla.
4. Lerako le ka hare le boreleli ebile ha le bonolo ho lekanya, 'me le na le mosebetsi oa ho itlhoekisa.
