1.Kana jecha rinoputika kana manual mechanical derusting rinoshandiswa, chiyero chesimbi chiri pamusoro pehombe-diameter simbi pombi inoratidzirwa zvakananga kumhepo nekuda kwekusvuura kwechiyero che oxide kubva kune yakakura-diameter simbi pombi.Kana primer isina kupendwa nenguva, pamusoro pepombi yesimbi yakakura-diameter inogona kuita ngura zvakare, iyo inokanganisa kunamatira kwefirimu yepende.Sezvo pendi iri chinhu chinobatika nenguva, iyo inventory backlog inokwanisa kupera nguva uye kuita kusashanda.Nokudaro, zviratidzo zvikuru zvepende zvinoongororwa zvakare zvisati zvashandiswa, uye zvigumisiro zvinosangana nehuwandu.

2.Derusting: Iyi ndiyo nzira inokosha isati yaputirwa ye-diameter-diameter simbi mapaipi uye zvikamu, uye ndiyo kiyi kune yakakura-diameter simbi mapaipi.Kubvisa ngura kunogona kuvandudza kunamatira kwependi ye-anti-rust, nekudaro kuwedzera hupenyu hwebasa remapaipi makuru-diameter esimbi.

3.Pamusoro pepombi yakakura-diameter yesimbi yakagadziriswa nejecha, kuputika kwepfuti kana pickling process inenge yakachena, uye oxide scale uye rust zvinenge zvakachena, izvo zvinovandudza kuvhara kwekunamatira.Kana nzvimbo yekumisikidza ichinge yarapwa nejecha uye kuputika kwepfuti, michina yemaoko inogona kushandiswa kubvisa ngura, asi nhanho yekubvisa ngura inosvika.
