Pressure Pipeline Materials Design for Natural Gas Low-temperature Separation Systems
In previous projects,the material specifications for low-temperature pressure pipelines in offshore oil and gas field process systems were based on ASTM A333 standards.Currently,there are corresponding national standards for low-temperature pipeline materials.To expand the selection range of materials for low-temperature pressure pipelines for offshore oil and gas,,this paper researches national standard pipeline materials that can replace ASTM A333 Gr6.Combined with the usage conditions of low-temperature alloy steel,this paper introduces standards and design methods that should be followed in design from the aspects of low-temperature pipeline material selection,pipeline wall thickness calculation and pipeline cold insulation.
