Standard Practice for Laser Technologies for Direct Measurement of Cross Sectional Shape of Pipeline and Conduit by Rotating Laser Diodes and CCTV Camera System

Importancia y uso:

4.1 Laser profiling assessment is a quality control tool for identifying and quantifying deformation, physical damage, and other pipe anomalies after installation, providing means and methods for determining the quality of workmanship and compliance with project specifications. Laser profiling capabilities include:

4.1.1 Measurement of the structural shape, cross sectional area and defects;

4.1.2 Collection of data needed for pipe rehabilitation or replacement design; and

4.1.3 Post rehabilitation, replacement or new construction workmanship verification.

4.2 A laser profile pre-acceptance and condition assessment survey provides significant information in a clear and concise manner, including but not limited to graphs and still frame digital images of pipe condition prior to acceptance, thereby providing objective data on the installed quality and percentage ovality, or degree of deformation, deflection or deviation, that is often not possible from an inspection by either a mandrel or only CCTV.
