Kuti tikwaniritse zosangalatsa zomwe makasitomala akuyembekezera, tili ndi gulu lathu lolimba kuti lipereke ntchito yathu yabwino koposa yomwe imaphatikizapo kutsatsa ndi kutsatsa, kugulitsa zinthu, kupanga, kupanga, kuyang'anira bwino, kulongedza, kusungirako katundu ndi mayendedwe a Seamless Welded Steel Tube / Carbon Mild Low Alloy Steel Pipe, Cholinga chathu ndi "kuyaka pansi kwatsopano, Kudutsa Mtengo", mtsogolomo, tikukuitanani moona mtima. sinthani nafe ndikupanga nthawi yowala limodzi! Kampani yathu yapanga ubale wokhazikika wamabizinesi ndi makampani ambiri odziwika bwino apakhomo komanso makasitomala akunja. Ndi cholinga chopereka zinthu zabwino kwambiri ndi mayankho kwa makasitomala pamabedi otsika, tadzipereka kupititsa patsogolo luso lake pakufufuza, chitukuko, kupanga ndi kasamalidwe. Ndife olemekezeka kulandira kuzindikiridwa ndi makasitomala athu. Mpaka pano tadutsa ISO9001in 2005 ndi ISO/TS16949 mu 2008. Mabizinesi a "khalidwe la kupulumuka, kukhulupirika kwachitukuko" pazifukwa zake, alandileni moona mtima amalonda apakhomo ndi akunja kudzacheza kukambirana za mgwirizano.
ASTM A672 ndi wamba mkulu-voltage electrofusion welded chitoliro mulingo. Kutentha kwazinthu zomwe zalembedwa muyeso ndi 20 ° C mpaka -195 ° C. Choncho, muyezo A672 nthawi zambiri ntchito mipope otsika kutentha welded. Pakati pawo, CC60 CL22 ndi zinthu zambiri ntchito otsika kutentha chitoliro zakuthupi, amene amapangidwa A516GR.60 sing'anga ndi otsika kutentha kuthamanga chotengera mpweya zitsulo mbale. Ndi chinthu chofunika kwa magetsi welded mapaipi. Kutentha koyeserera kumafunika kukhala -50 ° C, komwe kumatha kusinthidwa ndi zinthu zaku China Q345R. The chemical composition and mechanical properties of the two are same:
