What is the general minimum requirement for the radius of bends when using an intelligent pig for inspection?

• A. 3 diameters
• B. 5 diameters
• C. 7 diameters
• D. 10 diameters

Answer: (B)

The general minimum requirement for the radius of bends when using an intelligent pig for inspection is 5 diameters. This requirement is crucial because it ensures that the pig can navigate through the pipeline without getting stuck or damaged. A radius of 5 diameters allows for enough clearance for the pig's body and any appendages, reducing the risk of encountering excessive stresses or blockages during inspection. When the radius of a bend is smaller than this minimum requirement, it can lead to performance issues such as increased resistance, potential for the pig to become dislodged, or even potential damage to the pig itself. Additionally, utilizing a radius that meets the 5 diameters standard accommodates for the variety of pipelines and their respective design parameters, ensuring the integrity and effectiveness of the inspection process.
