Tianjin Yuantai Derun Gulu JCOE Φ1420 lalikuluchitoliro cha lsawgawo layikidwa kuti lizitse kusiyana kwa msika wa Tianjin
JCOE ndi ukadaulo wopanga mapaipi opangira mapaipi akuluakulu okhala ndi makoma okhuthala, kutengera njira yopangira ma arc welding okhala ndi mbali ziwiri, komwe chinthucho chimaphwanyidwa, kupindika, kupindika, kusokedwa, kupindika mkati, kupindika kunja, kuwongoledwa, ndi kutha m'njira zosiyanasiyana. Njira yopangira ikhoza kugawidwa m'magawo a N+1 (N ndi nambala yabwino), pomwe mbale yachitsulo imaperekedwa yokha ndikupindika mopingasa m'magawo okhazikika kuti CNC ipange JCO yopita patsogolo. Mbale yachitsulo imalowa mumakina opangira mbali yopingasa, ndipo imayendetsedwa ndi trolley yodyetsera kuti ichite gawo loyamba la masitepe a N/2 opindika mopingasa kuti ipange "J" ya theka loyamba la mbale yachitsulo; gawo lachiwiri poyamba limapangitsa mbale yachitsulo yopangidwa ndi "J" kupititsa patsogolo mwachangu kupita kumalo opingasa, kuchokera kumapeto ena a mbale yachitsulo yosapangidwa kuti ipange masitepe ena a N/2 opindika mopingasa, kuti ikwaniritse theka lachiwiri la kupanga mbale yachitsulo, kuti ikwaniritse kupanga "C"; Pomaliza, gawo la pansi la "C" chitoliro billet kupindika kamodzi kuti akwaniritse "Gawo lililonse la atolankhani limachokera pa mfundo yoyambira ya kupindika mfundo zitatu."
Chitoliro chachitsulo cha LSAWamachita gawo lofunika kwambiri pa nkhani zazikuluChitoliro cha mzere wa lsawmapulojekiti, mapulojekiti otumizira madzi ndi gasi, kumanga maukonde a mapaipi a m'mizinda, kukonza mipiringidzo ya milatho, kumanga matawuni ndi kumanga mizinda. M'zaka zaposachedwa, monga mtundu watsopano wa njira yomangira yosungira mphamvu komanso yosamalira chilengedwe, nyumba yomangira zitsulo yatamandidwa ngati "nyumba yobiriwira" ya m'zaka za m'ma 2000. Mu ndondomeko yomanga nyumba zazitali komanso zazitali kwambiri kuti mugwiritse ntchito njira yomangira zitsulo kapena konkire yachitsulo, nyumba zazikulu zomwe zimagwiritsa ntchito kapangidwe ka gridi ya malo, kapangidwe ka truss ka magawo atatu, kapangidwe ka nembanemba ya chingwe ndi dongosolo lomangira lomwe lakhala likukakamizidwa kale, izi ndi chitoliro chachitsulo pomanga zochitika zambiri, ndipo kufunikira kwa chitoliro chachitsulo chokhala ndi makoma akuluakulu kwawonjezeka kwambiri. Ndipotu,mapaipi a Lsaw ndi hsawZopangidwa ndi Yuantai Derun Steel Pipe Manufacturing Group zimagwiritsidwa ntchito kwambiri. Monga zapamwamba kwambiriwopanga mapaipi a lsawKu China, Yuantai Derun imagwira ntchito yopereka mapaipi achitsulo pa ntchito zambiri zazikulu.
Posachedwapa, Tianjin Yuantai Derun Steel Pipe Manufacturing Group yapereka satifiketi yokhudzana ndiChitoliro cha API 5L lsawndipo idzagwiritsidwa ntchito kwambiri m'magawo osiyanasiyana mtsogolo. Zogulitsa zazikulu zikuphatikizapoChitoliro chachitsulo cha kaboni cha Lsaw, chitoliro chachitsulo cha lsaw chachikulu m'mimba mwakendiChitoliro chachitsulo choswedwa cha Lsaw.
Gulu la JCOEΦ1420 la Tianjin Yuantai Derun Steel Pipe Manufacturing Group likhoza kupanga zinthu zosiyanasiyana kuyambira Φ355.6mm mpaka Φ1420mm m'mimba mwake ndi mpaka 50mm m'makoma makulidwe, zomwe zidzadzaza kusiyana kwa msika wa Tianjin pazinthu zotere zikayamba kugwira ntchito ndipo zitha kufupikitsa kwambiri nthawi yotsogolera yoyitanitsa mapaipi akuluakulu, ozungulira komanso ozungulira okhala ndi makoma akuluakulu. Chitoliro chachikulu cholumikizidwa ndi arc chokhala ndi mbali ziwiri chingagwiritsidwe ntchito mwachindunji potumiza mafuta ndi gasi, chitoliro chachitsulo cha JCOE chagwiritsidwa ntchito kwambiri mu projekiti yadziko lonse ya "West-East gas transmission", pomwe chitoliro chachitsulo chomangidwa chingagwiritsidwe ntchito pomanga kapangidwe kachitsulo chapamwamba kwambiri, kuwonjezera pa kugwiritsa ntchito njira ya "round to sikweya" ikhoza kukonzedwa kukhala mainchesi akuluakulu. Kuphatikiza apo, njira ya "round to sikweya" ikhoza kukonzedwa kukhala mapaipi achitsulo ang'onoang'ono ozungulira okhala ndi makoma akuluakulu, omwe angagwiritsidwe ntchito m'malo osangalatsa akuluakulu komanso kupanga makina olemera ndi zida.
