Te maimoatanga mata o te putorino maitai: Hei whakapai ake i te oranga ratonga o te pipeline hinu, ka whakahaerehia te maimoatanga mata ki te whakahaere i te whakakotahitanga o te putorino maitai me te paninga anticorrosive. Ko nga tikanga tukatuka noa ko: te horoi, te whakakore i nga taputapu, te kohi, te pupuhi pupuhi. e wha nga waahanga.1 te horoi Ko te hinu, te puehu, te whakahinuhinu, te mea pararopi e piri ana ki te mata o te putorino rino, te nuinga o te whakamahi i te whakarewa, te whakaehunga hei horoi i te mata.Heoi, ko te waikura, te kiri waikura, me te para whakahiato i runga i te mata o te putorino maitai e kore e taea te tango, na etahi atu e hiahiatia ana nga tikanga maimoatanga.Tool rust removalSteel pipe mata waikura, waikura, fehokotaki'anga para, ka taea te whakamahi i te paraihe waea maitai ki te horoi me te whakakoi i te mata treatment.Tool derusting ka taea te wehea ki a-ringa me te mana, ka taea e te derusting taputapu ā-ringa tae Sa 2 taumata, mana Ka taea e te whakakore i te taputapu te tae ki te taumata Sa3. Mena ka piri te mata o te paipa rino ki te kiri waikura tino kaha, ka kore pea e taea te tango i te waikura me te awhina o nga taputapu, na me rapu etahi atu huarahi.3 pickling Ko nga tikanga pikinga noa ko te matū me te electrolysis.Engari ko te tiki matū anake e whakamahia ana mo te tiaki i te waikura paipa.Ka taea e te pikau matū te whakatutuki i tetahi tohu o te ma me te taratara i runga i te mata o te paipa maitai, he pai mo nga raina punga o muri. pupuhi (kirikiri) i muri i te tukatuka ano.4 pupuhi pupuhi mo te tango waikuraNa te motuka mana nui te taraiwa tere tere tere, te kirikiri rino, te pupuhi rino, te waahanga, nga kohuke me etahi atu waea abrasive i raro i te mahi o te kaha centrifugal i runga i te rehu paipa rino me te pupuhi papatipu, tino tango i te waikura, waikura. me te paru i runga i tetahi ringa, i runga i te tahi atu te ringa, paipa maitai i raro i te mahi o te abrasive pānga tutu me te kaha waku, ki te whakatutuki i te roughness kākahu e hiahiatia ana.I roto i nga tikanga maimoatanga e wha, pupuhi ngingio me derusting ko te tikanga maimoatanga pai mo te putorino derusting.Ko te tikanga, ko te pupuhi pupuhi me te whakakore i te nuinga o te waa e whakamahia ana mo te maimoatanga mata o roto o te putorino maitai, a ko te pupuhi pupuhi me te pupuhi ka whakamahia mo te maimoatanga mata o waho o te putorino maitai.
