Pipeline distribution network system for transporting liquefied natural gas

摘要

(57) at a temperature of (-80 ° F) (-190 ° F) ~ about -62 ℃ about -123 ℃ and a pressure of about 1035kPa (150psia) ~ about 7590kPa of (1100psia) the [summary] pressurized liquid natural gas pipeline network delivery system to transport is provided. The nickel-containing less than 9% by weight, and other components of the tube pipeline delivery network system, ultra-low strong (-100 ° F) or below 830MPa tensile strength (120ksi) or more, DBTT is about -73 ℃ and a steel alloy.
