Pipeline distribution network systems for transportation of liquefied natural gas |
摘要 |
Pipeline distribution network systems arc provided for transporting pressurized liquefied natural gas at a pressure of about 1035 kPa (150 psia) to about 7590 kPa (1100 psia) and at a temperature of about -123° C. (-190° F.) to about -62° C. (-80° F.). Pipes and other components of the pipeline distribution network systems are constructed from an ultra-high strength, low alloy steel containing less than 9 wt % nickel and having a tensile strength greater than 830 MPa (120 ksi) and a DBTT lower than about -73° C. (-100° F.).
