[Current]Buried flexible pipelines, Part 1: Structural design
Specifies a practice for the structural design of buried flexible pipelines which rely upon side support to resist vertical loads. The practice applies to pipes with outside diameters equal to or greater than 75 mm, initial ring-bending stiffness equal to or greater than 1250 N/m/m and long-term ring-bending stiffness equal to or greater than 625 N/m/m.
