.... The pipe diameter and the wall thickness were 1219 mm and 18.4 mm, respectively. The operating pressure for the pressurized pipe models was set as 12 MPa (based on an applied safety factor of 0.72) [ 34 , 35 ]. The pipe considered here is at a burial depth of 2 m in a clay soil with a cohesive stress of 45...

... It should be noticed that the comparison of the solutions was done without taking into consideration the safety factor, because its use will make the B31.G, B31.G Mod, and DNV solutions very conservative. Also, its use requires detailed study due to the relationship of this factor with shape defect...
