Mwachidule
Tikukhulupirira kuti kuyanjana kwanthawi yayitali ndi chifukwa chapamwamba kwambiri, chithandizo chowonjezera, kukumana kolemera komanso kulumikizana kwanu ndi Carbon Steel Pipe, Timaonetsetsanso kuti ma assortment anu apangidwa mwaluso pogwiritsa ntchito mtundu wodalirika komanso wodalirika. Onetsetsani kuti muli ndi ufulu wolumikizana nafe kuti mudziwe zambiri komanso zowona. Timadziwitsidwa ngati m'modzi mwa omwe akukula opanga zinthu komanso kutumiza kunja kwa chitsulo cha carbon ndi alloy steel pipe. Tsopano tili ndi gulu la odziwa odzipereka ophunzitsidwa bwino omwe amasamalira bwino komanso munthawi yake. Ngati mukuyang'ana Ubwino Wabwino pamtengo wabwino komanso kutumiza munthawi yake. Lumikizanani nafe.
Chitoliro chopanda chitsulo cha A106 ndi chitoliro chopanda chitsulo chomwe chimagwiritsidwa ntchito kunyamula madzi otentha kwambiri monga madzi, mafuta ndi gasi. Chitsulo ichi chimakhala ndi mapindikidwe ozizira kwambiri komanso mapulasitiki apamwamba, kuzizira kozizira kapena kukhazikika bwino kuposa momwe zimakhalira, zomwe zimagwiritsidwa ntchito ngati mapaipi amadzimadzi, mapaipi apangidwe, mapaipi opopera otsika kwambiri omwe sapanikizika ndipo amafuna kulimba kwambiri.
Kugwiritsa ntchito
Chitoliro chosasunthika chachitsulo cha ntchito yotentha kwambiri ya ASTM A106, yoyenera kutentha kwambiri
