Monga wopanga wamkulu pantchito iyi,Malingaliro a kampani Cangzhou Spiral Steel Pipe Group Co., Ltd.mosamalitsa amatsatira mfundo za mayiko ndipo imakhazikika kupanga electrofusion arc weldedmipope yachitsulo yozungulirakuphimba magiredi asanu. Mtundu uwu waChitoliro chachitsulo cha ASTMamapangidwa mwapadera kuti azinyamula zamadzimadzi, mpweya kapena nthunzi, kuonetsetsa kuti zikuyenda bwino komanso moyenera m'malo osiyanasiyana opanikizika kwambiri komanso ovuta.
Mphamvu za kampaniyi zimachokera ku mphamvu zake zazikulu zopanga zapamwamba. Tili ndi mizere 13 yopangira zitsulo zozungulira komanso mizere 4 yoletsa kuwononga komanso kupanga matenthedwe, omwe amatha kupanga mapaipi achitsulo ozungulira okhala ndi mainchesi akunja kuyambira mamilimita 219 mpaka 3500 mamilimita ndi makulidwe a khoma mpaka mamilimita 25.4.
Zogulitsa zake za "Wuzhou" sizimangotsatira miyezo ingapo yapadziko lonse lapansi monga API Spec 5L ndi EN 10219, komanso zimakwaniritsa zofunikira pamiyezo yayikulu monga ASTM A139 ndi ASTM A252.
Mapaipi achitsulo aku China awa omwe amatsatira miyezo ya ASTM ali ndi zochitika zambiri zogwiritsa ntchito. Zakhala zikugwiritsidwa ntchito bwino pama projekiti ofunikira monga ma network operekera madzi am'matauni ndi ngalande, kayendedwe ka gasi wachilengedwe ndi mafuta akutali, ndi machitidwe a milu ya mapaipi, kupereka zoyendera zolimba komanso zokhazikika "zotengera zamagazi" zomanga zomangamanga padziko lonse lapansi.
Kusankha wopanga yemwe ali ndi ziphaso zapadziko lonse lapansi ndi gawo loyamba lotsimikizira kudalirika kwanthawi yayitali kwamapulojekiti a mapaipi. Gulu la Cangzhou Spiral Steel Pipe Group, lomwe limatsatira mosamalitsa miyezo ya ASTM komanso mphamvu zopangira zokhazikika, limapatsa makasitomala mayankho okhazikika kuyambira kupanga mpaka odana ndi dzimbiri.
Kuti mumve zambiri zamatchulidwe, tsatanetsatane wa certification ndi kuthekera kosintha makonda athu a ASTM standard-compliant spiral steel mapaipi, chonde lemberani gulu lathu la akatswiri kuti mumve zambiri zaukadaulo komanso mawu.
