Nekuenderera mberi kwekusimudzira hupfumi hweChina, nyika inovandudza indasitiri yemagetsi zvine simba.Pipeline kureba mafuta uye gasi mapaipi inzira yakakosha yekuchengetedza simba.Muchirongwa chekuvaka-anti-corrosion yemafuta (gasi) mapaipi, kurapwa kwepamusoro kwe-anti-corrosion spiral simbi pombi kunotaridza hupenyu hwesevhisi yepombi.Chimwe chezvinhu zvakakosha ndicho chikonzero chekuti anti-corrosion layer uye pombi yesimbi inogona kubatanidzwa zvakasimba.Zvinoenderana nekuongorora kwesangano rekutsvagisa, hupenyu hweiyo-anti-corrosion layer inotsamira pamhando yekuputira, kunaka kwekupfeka uye nharaunda yekuvaka.Kurapa kwepamusoro kwepombi ye-anti-corrosion spiral steel inokanganisa hupenyu hweiyo anti-corrosion layer ne50%.Nokudaro, inofanira kunge yakanyatsoenderana ne-anti-corrosion layer.Misa zvinodiwa pamusoro pemapombi esimbi, ramba uchiongorora uye kupfupikisa, uye ramba uchivandudza nzira dzekurapa dzepamusoro pepombi dzesimbi.

Chii chinofanira kuitwa pamusoro pepamusoro-frequency anti-corrosion spiral simbi pombi?

1. kuchenesa

Shandisa solvent uye emulsion kuchenesa pamusoro pesimbi kubvisa mafuta, girisi, guruva, lubricant uye zvakafanana organic zvinhu, asi haigoni kubvisa ngura, chiyero, flux, nezvimwewo pamusoro pesimbi pombi, saka inongoshandiswa se nzira yekubatsira mukugadzirwa kwe-anti-corrosion yepombi yesimbi..

2. mudziyo kubvisa ngura

Pamusoro pepombi yesimbi inonyanya kukwenenzverwa nekushandisa bhurasho rewaya kana zvimwe zvakadaro kubvisa chiyero chakasunungurwa kana kusimudzwa, ngura, welding slag, nezvimwe zvakadaro.Kubvisa ngura kwechishandiso chemaoko kunogona kusvika pachiyero cheSa2, uye kubviswa kwehutu kwechigadziro chemagetsi kunogona kusvika pachiyero cheSa3.Kana iyo yepamusoro yesimbi yesimbi yakanamatira kune iron oxide chiyero, ngura yekubvisa mhedzisiro yechishandiso haina kunaka, uye kudzika kweanchor kunodiwa pakuvakwa kwe-anti-corrosion hakugone kuwanikwa.

3. pickling

Kazhinji, kuchenesa kemikari uye electrolysis inoshandiswa pakunhonga kurapwa.Anticorrosive spiral simbi pombi inobatwa chete nekemikari pickling, iyo inogona kubvisa chiyero, ngura uye chekare kupfekedza, uye dzimwe nguva inogona kushandiswa sekurapazve mushure mekuputika kwejecha uye kubvisa ngura.Kunyangwe kuchenesa makemikari kunogona kuwana imwe nhanho yehutsanana uye kushata, patani yeanchor yayo haina kudzika uye zviri nyore kusvibisa nharaunda.
