Pipeline Cold Bend Calculations

A: That's the most common mistake — assuming SMYS compliance covers everything. The difference matters because cold bending primarily drives longitudinal strain and ovalization, which erodes collapse margin long before you see hoop-stress-driven failure.

A: That's the most common mistake — importing strain-based limits where the governing document never invoked them. The difference matters because, in a brownfield onshore system, code-based elastic-plastic checks are what the regulator will audit against today.

A: That's the most common mistake — trusting indirect evidence. The difference matters because only geometric measurement lets you quantify strain before you stack pressure and thermal loads on top.

A: That's the most common mistake — thinking fracture control is geometry-agnostic. The difference matters because bending strain adds to pressure stress, shifting you off the arrest curve without ever violating MAWP.
