Ke sekoaelo sa tšebetso se phahameng se thibelang kutu. Sehlahisoa se na le khanyetso e ntle ea lik'hemik'hale le ho hanyetsa metsi.
E sebetsa ho thibela ho bola ha lipeipi tsa oli, khase le metsi, metsi a lipompo, khase, liphaephe, lihloekisi tsa oli, lifeme tsa lik'hemik'hale le lifeme tsa likhoerekhoere. E ka boela ea sebelisoa e le mokhoa oa ho thibela ho bola ha lifolamo tsa ho cheka oli kantle ho leoatle le likarolo tse ka tlas'a metsi tsa likepe, hammoho le ho thibela ho bola ha merafo le lisebelisoa tse ka tlas'a lefatše.
Sebopeho se matla sa polyethylene se thibelang ho senya: phala ea tšepe e phuthetsoe ka thepa ea polyethylene e phahameng haholo, e nang le matla a phahameng a mochine le ho hanyetsa ha kutu, 'me e ka sireletsa phala ea tšepe tšenyo e bakoang ke lintlha tse ka ntle nakong ea lipalangoang, ho kenya le ho sebelisoa. Antioxidant, ultraviolet stabilizer, carbon black, joalo-joalo li tla kenyelletsoa ha ho etsoa letsoho la ka ntle. Lesela le ka ntle la polyethylene le bonolo ho tsofala. Haeba e bolokiloe sebakeng se bulehileng, e lokela ho koaheloa ka seile le lisebelisoa tse ling. Sebaka sa stacking se lokela ho ba hole le mohloli oa mocheso o phahameng le mohloli oa mollo. Ka mor'a hore pipe ea tšepe e khahlanong le kutu e etsoe, e thibetsoe ho pepeseha letsatsing le ho tima, ho seng joalo sleeve ea ka ntle ea polyethylene e bonolo ho senya le ho ama ts'ebetso ea sehlahisoa le bophelo ba tšebeletso.
Epoxy phofo e koahetsoe ke mokhoa oa ho fafatsa ka electrostatic. Ka lebaka la bothata ba ho khomarela ha epoxy powder impregnation process, ho kenngoa ha phofo ea epoxy ha hoa tsebahala. Hona joale, ka nts'etsopele e atlehileng ea tharollo e khethehileng ea phosphating bakeng sa ho kenngoa ha phofo ea epoxy ea Sanye, bothata ba ho khomarela ha epoxy powder impregnation process e hlōtsoe ka lekhetlo la pele, 'me mokhoa o hlahang oa ho kenngoa ha phofo ea epoxy o qalile ho hlaha.
Lisebelisoa tsa motheo tsa lipeipi tsa tšepe tse thibelang ho bola li kenyelletsa liphaephe tsa spiral, liphaephe tse otlolohileng tsa seam, lipeipi tse se nang moeli, joalo-joalo Chaena, li sebelisoa haholo libakeng tsa boenjiniere ba liphaephe tse kang phetisetso ea metsi a malelele, peterole, indasteri ea lik'hemik'hale, khase ea tlhaho, mocheso. , tlhoekiso ea likhoerekhoere, mohloli oa metsi, borokho, mohaho oa tšepe, phetisetso ea metsi a leoatleng le liqubu.
