Mphotho zathu ndi zotsika mtengo, gulu lochita zopindulitsa, QC yapadera, mafakitale amphamvu, ntchito zapamwamba kwambiri za 2019 JIS G3454/G3455/G3456 Carbon Steel Seamless Pipe, Takulandilani makasitomala padziko lonse lapansi kuti atiyimbire kampani ndi mgwirizano wanthawi yayitali.Tikhala bwenzi lanu lodalirika komanso ogulitsa.
Mphotho zathu ndi zotsika mtengo, gulu lopindula lamphamvu, QC yapadera, mafakitale amphamvu, ntchito zapamwamba kwambiri zaChina Carbon Steel Pipe ndi Seamless Steel Pipe, Kuti tikwaniritse zofuna za msika, tsopano tapereka chidwi kwambiri pa ubwino wa zothetsera ndi ntchito zathu.Tsopano tikhoza kukwaniritsa zofunika makasitomala 'pa mapangidwe apadera.Timalimbikira kukulitsa mzimu wathu wamabizinesi "ubwino umakhalira bizinesi, ngongole imatsimikizira mgwirizano ndikusunga mawu athu m'malingaliro athu: makasitomala choyamba.
Chitoliro cholamulidwa pansi pa ndondomekoyi chimagwiritsidwa ntchito pa ntchito yothamanga kwambiri pamlengalenga ndi kutentha kwapansi.Amagwiritsidwa ntchito kwambiri pofalitsa mafuta ndi gasi.
Chithunzi cha ASTM A671LSAW(JCOE) Carbon Steel Pipeadzakhala ndi ma welds awiri, olowera kwathunthu opangidwa motsatira ndondomeko komanso ndi owotcherera kapena owotcherera oyenerera malinga ndi ASME Boiler ndi pressure Vessel Code, Gawo IX.
Makalasi onse kupatula 10, 11, 12 ndi 13 azitenthedwa mu ng'anjo yoyendetsedwa mpaka ± 15 ℃ ndikukhala ndi chojambulira chojambulira kuti zolemba zotentha zizipezeka.
