Ka papa helu kumu kūʻai kūʻai no ke kiʻekiʻe kiʻekiʻe Cold Rolled Q355B 16Mn C20 ASTM A36 Seamless Carbon Steel Pipe
ʻO ka wehewehe pōkole:
ʻO ka paipu kila Q355 he paipu kila kiʻekiʻe kiʻekiʻe Kina, kahi i hoʻololi ai iā Q345, ʻo ka nui o nā mea he 7.85 g / cm3.Wahi a GB / T 1591 -2018, loaʻa iā Q355 nā pae kiʻekiʻe 3: Q355B, Q355C a me Q355D.
ʻO ka paipu kila Q355 he mea haʻahaʻa haʻahaʻa, ke kila ikaika kiʻekiʻe i hoʻohana ʻia i nā hale welded e kākoʻo ana i ke kaumaha a me nā ukana kaumaha.Hōʻike ka Q i ka helu hua, a ʻo ka helu 355 e hōʻike ana i kona ikaika hua.
ʻO nā hiʻohiʻona o Q355 Pipe kila
ʻO ka paipu kila Q355 he kila kila me ka ikaika o ka 345 MPa a me ka ikaika tensile o 450 MPa.Loaʻa iā ia ka hana hoʻoponopono maikaʻi a me ka ikaika compressive, hiki ke hoʻohana ʻia no ka hana ʻana i nā kīʻaha kiʻekiʻe kiʻekiʻe i loaʻa ma lalo o 500 lita.Loaʻa iā Q355 kahi papa pale o ka pale ʻana i ka ʻōpala.
Nā hoʻohana ʻana i ka paipu kila Q355
Q355 paipu kila i maikaʻi mechanical waiwai, weldability nui, a ample corrosion kū'ē.Hiki ke hoʻohana ʻia no ka hana ʻana a me ka hana ʻana i nā pahu mālama ʻaila, nā moku kiʻekiʻe, nā boilers, nā moku, nā kikowaena mana, a me nā ʻāpana hana kiʻekiʻe.
Nui: 34mm-610mm.
WT: 3.5mm-50 mm.
ʻAno: Poe.
ʻAno hana: ʻōwili wela a i hoʻopau ʻia paha.
Ka lōʻihi: Hoʻokahi wale nō ka lōʻihi / ʻelua manawaleʻa lōʻihi a i ʻole ke noi maoli ʻana o ka mea kūʻai aku max ka lōʻihi he 12m
Ke manaʻo nei kā mākou paʻa e hana pono, lawelawe i kā mākou poʻe kūʻai a pau, a me ka hana ʻana i ka ʻenehana hou a me ka mīkini hou e like me ka Cheap PriceList for High Pressure Cold Rolled Q355B 16Mn C20 ASTM A36 Seamless Carbon Steel Pipe, Ke kali nei mākou i ka hoʻokumu ʻana i nā pilina pili me oe.E ʻoluʻolu e kelepona mai iā mākou no ka ʻike hou aku.
Manaʻo kā mākou ʻoihana e hana pono, lawelawe i kā mākou poʻe kūʻai āpau, a me ka hana mau ʻana i ka ʻenehana hou a me ka mīkini hou.Paipu kila kabone Kina a me ka paipu kila hala ole, Me nā makahiki he nui ka lawelawe maikaʻi a me ka hoʻomohala ʻana, loaʻa iā mākou kahi hui kūʻai kālepa kālepa honua.Ua lawe aku kā mākou huahana i ʻAmelika ʻĀkau, ʻEulopa, Iapana, Korea, Australia, New Zealand, Russia a me nā ʻāina ʻē aʻe.Ke nānā nei i mua e kūkulu i kahi hui maikaʻi a lōʻihi me ʻoe i ka wā e hiki mai ana!
