33.4X4.55 88.9X7.62 219.1X8.18 ASTM A333 Gr6 low temperature seamless steel tubes
1.Torich A333 Gr6 is a nickel-free low-temperature steel pipe, Gr6 low temperature seamless tubes is a fine-grained low-
temperature toughness steel with aluminum deoxidation, and its metallographic structure is body-centered cubic ferrite.
Bolier tubes with Gr6 usually delivered in normalized or normalized and tempered state.
Low temperature seamless steel pipes A333 Gr6 are mainly used in
the production of ethylene, propylene, urea, synthetic
ammonia, N-P_K compound fertilizers and pharmaceutical industries with petrochemical natural gas and coal as raw materials
for washing, purification, desulfurization and degreasing, as well as cryogenic equipment manufacturing. , Ultra-low temperature
cold storage, conveying ultra-low temperature liquefied gas pipeline and its pipe parts. Suitable for low temperature environment
as low as -196℃. Among the 9 low temperature grades, Gr 6 is widely used in petrochemical industry and fluid transportation in
low temperature and alpine regions.
