To calculate pup-piece length for a 12 inch pipeline with two sections already lowered and overlap 5m and s-bend rolling, two 90 degree LR bends.

• Calculate the total length of the pipeline

• Subtract the length of the two sections already lowered and overlap 5m

• Add the length of the two 90 degree LR bends

• Divide the result by 2 to get the length of each pup-piece

Collapse and damage percentage for HDD crossings are calculated based on various factors such as soil type, borehole diameter, and drilling fluid properties.

• Collapse percentage is calculated using the Mohr-Coulomb failure criterion

• Damage percentage is calculated based on the tensile strength of the pipe and the bending stress induced during the pullback process

• Factors such as soil type, borehole diameter, and drilling ...read more
