None metallic pies such as PVC, HDPE, GRE,
GRP etc. are subject to deformation during construction and changing
soil loads. ATV WRC recommends carrying out deflection surveys at
various intervals of line construction. Qualitative inspections of newly
constructed lines are recorded and deflections outside acceptable limits
detected at an early stage.
provides deflection measurement surveys in line with these standards.
units can be applied separately or combined together with CCTV
inspection survey. The measuring probes scan the surface of the pipe and
measure the pipe diameter in both the vertical and the horizontal plane.
Independent data logger records all measured value at preset intervals.
Two measuring probes are used for pipe diameters between DN150 mm and
420 mm, and pipes between DN450 mm and 800 mm can be measured.
