Mea Hoʻolako Kina Sch40 DN15 Q235B Q355b API 5L Q345b Chromoly Carbon ʻEleʻele Mānoanoa Pā Nui Anawaena Anuu i unuhi ʻia ke kila maʻemaʻe ʻole.
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, kila ikaika kiʻekiʻe i hoʻohana ʻia i nā hale welded e kākoʻo ana i ke koʻikoʻi 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.
