ASTM A335 Alloy Steel Seamless Paipu

ASTM A335 Alloy Steel Seamless Pipe Kiʻi ʻia

ʻO ka wehewehe pōkole:

Ua kapa pinepine ʻia ʻo ASTM A335 he paipu chrome moly no ka loaʻa ʻana o ke kemika o Molybdenum (Mo) a me Chromium (Cr).Hoʻonui ka Molybdenum i ka ikaika o ke kila a ʻo Chromium (a i ʻole chrome) ka mea nui o ke kila kila.ʻO ka chrome moly alloy steel pipe ka mea i kūpono no ka hoʻohana ʻana i nā mea kanu mana, nā mea hoʻomaʻemaʻe, nā mea kanu kemika, a me nā lawelawe ʻaila aila kahi e lawe ʻia ai nā wai a me nā kinoea i nā wela kiʻekiʻe loa a me nā kaomi.
