Our team at Can-Explore conducts ovalization tests to ensure that pipes are not deformed beyond allowable limits set out in BNQ standards. Our ovalization tests use gauges adapted to the diameters of the pipes inspected.
Validation of acceptable maximum deformation
Specific gauges for each pipe diameter
Deformation studies using a laser profilometer
The gauges we use are specifically designed for each pipe diameter and enable us to measure the maximum allowable deflection (deformation), i.e. 5% after construction and 7.5% after one year. The team at Can-Explore is also able to conduct deformation studies using a laser profilometer in order to validate and identify deformations along the full length of the pipe even if certain sections are significantly deformed.
