Kaiyayyakin steel straight seam mai aiki da kungiyar piling daya suna rubutu mai aiki da kungiyar structure na sabon gari. Suna ke tabbata wani hanyar diameter da thickness don ake son ruwan tallafiya da stability da aka samun kungiyar foundation don construction na sabon gari. Wannan ne wannan makala kawai don kaiyayyakin steel straight seam don kungiyar piling daya:
Ji anfani da tsarin kwayoyin: Kula na faruwa mai watsa yanzu suna aiki masu gaba da cikakken jini da tsari, kuma suna wannan kwayoyin. Misali, tsari na shirin da 402MPa da tsari na kwayoyin da 235.2MPa, ko ana so suke amfani da talakaƙe da aka saita.
Tare da aiki: Kula na faruwa mai watsa yanzu suna takardunna aiki, game da kula na faruwa mai watsa da kula na faruwa mai watsa. Kula na faruwa mai watsa suna aiki mai kyautar daidai ne daga cikin aiki, bakon idan aiki na faruwa mai watsa suna wannan lokaci mai amfani.
Kattun da gabatarwa: Na karfi da hanyoyi mai alamarsa, kula na faruwa mai watsa suna gabatarwa mai sabon kula, kula ta gabatarwa na faruwar kula da gabatarwa na faruwar kula da gabatarwa na faruwar kula. Kattun akan gabatarwa na faruwar kula ya kamata ga 13m ko 15m.
Gaba: Kallashi na kallashi a cikin gida su daidai, rigidity su ne yanzu, kuma ya kamata a tsaye, shigar da rubutu, daidaita da idakaƙe, suka yi ba da watsiya. Babban wannan suna daidai, suka iya sosai kula a cikin tsohon hard soil da aka samun hanyar dukkan kallashi.
Fara daidai: Lissafi na kallashi suka iya fara daidai daya zuwa kamar bayani da aka samun, kuma suka tambaya daga cikin fasalin daidai.
Tsunfa daidai: Design na kallashin open a kanin kallashi na kallashi a cikin gida suka samun kasance masu rubutu a cikin tunani da aka samun, suka yi ba da watsiya haifuwa a cikin gida da aka samun.
Hanyar connection: Hanyar connection su ne yanzu, kuma suka iya amfani da electric welding, suka yi ba da watsiya, babban rigidity da safe da idakaƙe.
Sabon tsuntsuwan tunani: Sabon tsuntsuwa su ne yanzu, sabon tunani su ne yanzu, suka yi ba da watsiya, suka yi ba da watsiya, suka yi ba da watsiya.
Rubutun rubutuwa: Rubutun rubutuwa daya-daya diameter steel pipes shi a cikin rubutuwa tabbata, edge milling, pre-bending, forming, pre-welding, internal da external welding, finishing ne da haka steps.
Mai amfani: Straight seam steel pipes shi kuma yanzu a cikin rubutuwa daya-daya fluid transmission, chemical da chemical pipelines, high-grade construction steel, pipeline steel da aka biyu high-grade materials. Shi na fitar da production of steel supports, steel pipe columns, lattice columns, steel purlins, steel protection, da aka biyu.
A cikin kwayoyi, large straight-slit steel pipes don subway piling shi yanzu a cikin construction of subways da aka biyu infrastructure don wannan mai tsarin, construction performance da reliability.
