Wall Loss, Coatings, Restriction, Deformation. . .

Laser pipe profiling can be used to measure defects and features in many different materials and sizes and types of piping. The applications of the laser profiler range from underground drainage systems to pipelines, process pipes and even vertical piping such as flare stacks.

PVC/HDPE 

PVC/HDPE piping inspections are excellent for detecting the slightest deformations and changes in pipe profiles. Underground utilities such as electrical conduits, transfer lines and methane gas lines often develop some kind of deformation or ovality over the years. Ground shifting and settling, traffic, and other changes can cause pipe restrictions. This reduces flow and increases maintenance. The laser pipe profiling can quickly pinpoint problem areas without the need to guess where to excavate and repair.

Using Laser Pipe Profiling in PVC and HDPE piping

 

Pipe Linings and Coatings

Pipe lining and coatings may degrade in aging underground systems, such as injection, process or utility lines. The laser profiler can determine the extent of material loss. It can also calculate a cross-section of actual pipe versus the expected true diameter of the pipe. This provides our clients with accurate measurements including details of deficiencies such as location, clock positioning and any noted bulging or defects. Common applications include adding laser profiling on to video inspections of gas prover coatings and cement-lined produced water piping.

Carbon & Stainless Steel

Carbon & Stainless Steel pipelines and process piping are another great opportunity to exploit the laser pipe profiler for long distance runs. The profiler can calculate and analyse over great lengths. In a single pass, the system will gather data on restriction from build-up versus the expected true diameter of the piping. This information is especially useful for cleaning contractors who need to know the exact build-up remaining before and after cleaning.

Erosion and corrosion can also be detected using the profiler in pipelines. This provides details such as the clock positions of the surface wear, distance of wear from the pipe opening, and how much material loss has changed the pipe’s internal diameter comparatively throughout the length of the inspection.

Maverick uses remote video inspection and laser pipe profiling to confirm cleaning procedures.

 

Cement & Concrete

Concrete Pipe is common in underground drainage system such as storm, sanitation, oily water and chemical sewers. Concrete may deteriorate differently with time and use compared to PVC and carbon steel piping. The laser pipe profiler can help determine life expectancy on this type of material.

Build-up and sediment depths can be measured using the profiler to calculate the pipe capacity before and after cleaning. True diameter and material loss are easily detected using the laser profiler giving our clients the exact locations that may require rehabilitation or replacement. The structural shape, cross sectional area and defects are visible when using the profiler giving on-site, fast and reliable data for repairs or cleaning.
