Mwachidule
Timayesa kuchita bwino, kuthandizira makasitomala", tikuyembekeza kukhala gulu lalikulu la mgwirizano ndi bizinesi yolamulira kwa ogwira ntchito, ogulitsa ndi ogula, timazindikira kuti ndiyenera kugawana nawo ndikutsatsa mosalekeza kwa Carbon Steel Seamless Tube/Pipe, Kupatula apo, kampani yathu imamatira kwambiri komanso mtengo wotsika mtengo, ndipo timaperekanso makampani akuluakulu a OEM kumakampani ambiri otchuka, takhazikitsa njira yopangira mtundu ndikusintha mzimu wa "utumiki wodzipereka kwa anthu", ndi cholinga chofuna kuzindikirika padziko lonse lapansi. ndi chitukuko chokhazikika.
ASTM A106 GR. B Chitoliro chachitsulo chosasunthika chimakhala ndi ntchito yabwino yowotcherera. Chifukwa cha kuchepa kwa C, nthawi zambiri palibe cholimba kwambiri chifukwa cha kuwotcherera, ndipo cholumikizira chowotcherera chimakhala ndi pulasitiki wabwino komanso kulimba. Njira yonse yowotcherera imatha kupeza kulumikizana kokwanira kowotcherera popanda miyeso yapadera yaukadaulo.
ASTM A106 GR. B ndi 20 # ndizofanana mukupanga mankhwala ndi makina ndipo nthawi zambiri zimalowetsedwa m'malo mwa wina ndi mzake, koma kusiyana kulipo, makamaka pokhudzana ndi zofunikira zogwiritsira ntchito zowonjezera. wa GB8163 20# chubu chachitsulo ndi -19 ℃, pamene ASMR B31.3 imati kutentha kocheperako kwa A106 GR. B chubu lachitsulo ndi -29 ℃, ndipo pali chikhalidwe chopanda mayesero okhudzidwa.Ngakhale pali kusiyana kwa mapangidwe apangidwe, chifukwa chakuya ndi kusiyana kwa kayendetsedwe ka kayendetsedwe ka Mn.Wopanga sangadziwe zowonjezera izi. , koma wogula ayenera kudziwa kusiyana kumeneku ndikudziwitsa wopanga zomwe akufuna panthawi yogula, apo ayi mavuto angabwere pansi pa zofunikira zokhwima.
Kugwiritsa ntchito
Chitoliro chopanda chitsulo chopanda ntchito cha ASTM A106, choyenera kutentha kwambiri
