    Kumvetsetsa Kufunika Kwa Chitoliro Cha Gesi Yachilengedwe: X42 SSAW Pipe, ASTM A139 ndi EN10219

    Kumvetsetsa Kufunika kwa Chitoliro cha Gasi Wachilengedwe: X42 SSAW Pipe, ASTM A139 ndi EN10219 Chithunzi Chowonetsedwa
    • Kumvetsetsa Kufunika Kwa Chitoliro Cha Gesi Yachilengedwe: X42 SSAW Pipe, ASTM A139 ndi EN10219

    Kufotokozera Kwachidule:

    Pankhani ya kayendedwe ka gasi, njira zoyendetsera mapaipi zimagwira ntchito yofunika kwambiri powonetsetsa kuti gwero lamtengo wapatalili likuperekedwa moyenera komanso moyenera.chitoliro cha gasi kusankha ndi chisankho chofunikira chifukwa chimakhudza mwachindunji kudalirika ndi chitetezo cha makina onse ogawa gasi.Mu blog iyi, tifufuza za kufunikira kwa chitoliro cha gasi wachilengedwe, kuyang'ana pa X42 SSAW chitoliro, ASTM A139, ndi EN10219.

     x42SSAWchitolirondi mtundu wa chitoliro cha gasi chomwe chimagwiritsidwa ntchito popanga mafuta ndi gasi.Amapangidwa pogwiritsa ntchito njira yowotcherera ya arc yomwe ili pansi pamadzi yomwe imapanga mapaipi apamwamba komanso olimba.Chitoliro cha X42 SSAW chili ndi mphamvu zambiri komanso mankhwala abwino kwambiri, ndikupangitsa kuti ikhale yoyenera pazofunikira zoyendera gasi.Kukaniza kwake kwa dzimbiri ndi ming'alu kumapangitsa kukhala chisankho choyamba pama projekiti omanga mapaipi.

     ASTM A139ndi muyezo wina wofunikira wamapaipi achilengedwe a gasi.Izi zimakwirira chitoliro cha electrofusion (arc) chowotcherera chowongoka kapena chozungulira chomwe chimagwiritsidwa ntchito potumiza mpweya, nthunzi, madzi ndi zakumwa zina.Chitoliro cha ASTM A139 chimadziwika chifukwa chodalirika komanso kugwira ntchito kwanthawi yayitali pansi pazovuta kwambiri.Mapaipiwa amapangidwa kuti athe kupirira kupsinjika kwakukulu ndi kusinthasintha kwa kutentha, kuwapangitsa kukhala abwino kwambiri potumiza gasi wachilengedwe ndi ntchito zogawa.
