Gasi wachilengedwe ndi waukhondo, wothandiza, wosavuta komanso wapamwamba kwambiri wamagetsi ndi zida zamagetsi.Kugwiritsiridwa ntchito kwake ndi kugwiritsiridwa ntchito kwake kuli ndi phindu lalikulu pazachuma, chikhalidwe ndi chilengedwe.Ndi chitukuko china cha gasi lachilengedwe la China, mafakitale a gasi adzakumana ndi mwayi watsopano, akukumananso ndi zovuta zatsopano.Kusintha kwa maukonde a chitoliro choyambirira kapena kuyala maukonde atsopano a chitoliro kuyenera kutsindika chitetezo, kuthetsa chiopsezo chonse.Monga tikuonera pa maukonde chitoliro kunyumba ndi kunja, chifukwa cha ngozi, chifukwa cha ngozi zowononga munthu mlandu payipi dzimbiri kuwonongeka (kuphatikizapo nkhawa dzimbiri akulimbana) malo achiwiri.Zotsirizirazi nthawi zambiri zimakhala zovuta kuzizindikira, nthawi zambiri zimanyalanyazidwa, kuwonongeka kwa mapaipi mosakayikira ndikofunikira kutchulidwa.
The mkulu anticorrosion zokutira ntchito
The njira yaikulu ya m'banja ndi mayiko mobisa gasi dzimbiri payipi ndi oyenera zochokera payipi malo, malo, zinthu zachilengedwe, kuphimba kuwonjezeredwa ndi cathodic chitetezo.Utoto wogwiritsidwa ntchito: petroleum asphalt, malasha phula enamel, utoto wa epoxy.Paipi yokwiriridwa m'nyumba yolimbana ndi dzimbiri yomwe imagwiritsidwa ntchito kwambiri ndi petroleum asphalt penti.Ngati nthaka, tizilombo tating'onoting'ono, palibe kusokoneza kwambiri ndi zomera zozama kwambiri, zitha kuonedwa ngati zosanjikiza zothana ndi dzimbiri.Kuthamanga kwake sikuli koyenera kwa malo otentha kwambiri komanso kuwonongeka kwakukulu kwa chilengedwe panthawi yomanga, kugwiritsidwa ntchito kwake kwawonetsa kutsika.Kuchokera pamalingaliro apadziko lonse lapansi, omwe amagwiritsidwa ntchito kwambiri akakankhira enamel ya malasha ndi utoto wa epoxy.Zakale zimakhala ndi dzimbiri zamphamvu zotsutsana ndi tizilombo toyambitsa matenda, kulowa muzu wotsutsana ndi zomera, kuyamwa kwamadzi otsika, kukana cathodic delamination, kugwirizanitsa kukulungidwa kolimba pakhoma, pali ubwino woonekeratu wogwiritsidwa ntchito mu payipi yamafuta ndi gasi United States, Russia. , pakugwiritsa ntchito kwakukulu.
Pipeline ❖ kuyanika kutsogolo pamwamba pretreatment ndondomeko kusintha
The zotetezera khalidwe zimadalira mlingo wa TACHIMATA pamwamba pamwamba pretreatment njira kusankha.Dongosolo lochotsa dzimbiri Lamulo la nthawi ndi kuipitsidwa kwa anthu ogwira ntchito ndizovuta kutsimikizira mtundu.M'zaka zaposachedwapa chizolowezi ntchito kutentha unglazed lamulo degreasing, chitoliro Mumakonda mu ng'anjo mwapadera pa 350 ~ 400 ℃ kuonjezera mpweya wabwino, kutchinjiriza 3 ~ 4 h, mafuta anawotcha chitsimikizo degreasing khalidwe.Peening makina m'malo mwa chikhalidwe njira pickling.Njira imeneyi ndi ntchito wothinikizidwa mpweya kunyamula zitsulo kuwombera (kapena mchenga) kupanga mkulu-liwiro otaya mayendedwe amphamvu kwambiri pa zitsulo pamwamba pa nozzle wa mfuti kuchotsa mafuta kapena okusayidi.Imachita dzimbiri kwathunthu, komanso imapangitsa kuti pakhale roughness pamwamba, kuwonjezera malo okhudzana ndi khoma ndi zokutira (pafupifupi nthawi 20), komanso kupititsa patsogolo kulimba kwa ma bond, zitha kupewedwa bwino.
