Kukosha kwekugadzira longitudinal seam yakanyura-arc welded pombi

Parizvino, mapaipi anonyanya kushandiswa kutakura oiri kure kure uye gasi. Pipeline simbi mapaipi anoshandiswa mumapaipi akareba anonyanya kusanganisiraspiral undermerged arc welded simbi mapaipiuye musono wakatwasuka kaviri-mativi akanyura arc welded simbi pombi. Nekuti iyo spiral yakanyura arc welded pombi inogadzirwa ne strip simbi uye ukobvu hwayo hwemadziro hushoma, kuvandudzwa kwegiredhi resimbi kunogumira nekupisa kwekupisa kwezvinhu. Mukuwedzera, kune zvimwe zvisingakundiki kukanganisa kwe spiral submerged arc welded pombi, senge weld refu, yakakura yakasara kusagadzikana uye kusavimbika kwe weld. Nekuwedzera kwezvinodiwa zveoiri uye gasi kutapurirana simbi pombi, ivo havachashandiswa munzvimbo dzine vanhu vakawanda uye nzvimbo dzine kuvimbika kwakanyanya zvinodiwa, uyehombe-dhayamita yakatwasuka welded mapaipizvishoma nezvishoma vari kutsiva spiral welded pombi.

Munguva pfupi yapfuura, China iri kukurumidza kuvandudzwa kwemafuta uye gasi muEast China Sea. Nekuvandudzwa kwekushandiswa kwemafuta kusvika pakadzika pegungwa, pombi iri pasi pegungwa inokanganiswa nekubatana kwesimba rekumanikidza, simba rekuita uye kukotamisa simba, uye chiitiko chekufuga chichiri kuoneka, chinova chinongedzo chisina kusimba che spiral welded. pombi. Kuti uvandudze pombi yekufambisa uye kuve nechokwadi chekuti pombi yepasi pemvura kuti ikwire yakananga kumadziro akakora, pombi yepasi pemvura inonyanya kutora pombi yakasungwa yakatwasuka. Naizvozvo, kana zvichienzaniswa ne spiral welded pombi, yakatwasuka welded pombi ine yakakwirira dimensional kurongeka uye nyore kugadzirisa welding, saka kubva pachinhu ichi, yakatwasuka welded pombi ndiyo yekutanga sarudzo.

Michina, kuvaka, indasitiri yemakemikari uye mamwe maindasitiri anoda mapombi akatwasuka. Parizvino, gomba remukati rechigaro chevharuvhu rakagadzirwa mushure mekugadzira muindasitiri yemakina, iyo inopedza basa, inopedza nguva uye inopedza zvinhu. Kana gobvu-yakavezwa yakatwasuka seam welded pombi ikashandiswa, ichave yakanyanya hupfumi. Mukuwedzera, nekuda kwezvinodiwa zvema mechanical properties ye-anti-flattening, chete yakananga welded pipes inoshandiswa pakuvaka mapaipi; Pombi yakakwenenzverwa yakatwasuka inotarisirwawo kushandiswa pamapombi emakemikari.
