  • Combined application of Pipe Penetrating Radar and LIDAR for large diameter pipe inspection

    Abstract: Pipe Penetrating Radar (PPR) is the underground in-pipe application of ground penetrating radar (GPR), a non-destructive testing method that can detect defects and cavities within and outside mainline diameter (>18 in./450mm) non-metallic (reinforced concrete, vitrified clay, PVC, HDPE, etc.) underground pipes. Light Detection and Ranging (LIDAR) has become an accepted method for ...

  • Robot Device for Pipe Inspection - Case Study

    In 2005, Pure Technologies (Pure), a provider of various structural monitoring and leak-detection technologies, set about to develop a pipeline assessment tool that could monitor and report on the condition of pre-stressed concrete cylinder pipes (PCCP) utilized in municipal water and sewer systems. The tool’s competitive advantage would be accurate assessment decoupled from the need to ...

  • A Monster Pipe Demands Monster-Size Inspection Approach

    From a purely visual perspective, some pipeline inspections are more awe-inspiring than others. This is especially true when everyone involved describes the pipe diameter as “monster-size,” clocking in at 210 inches in diameter. A challenge of this magnitude requires fresh thinking from an inspection approach, especially when the subject pipe is so critical to the lifeblood of the ...

  • Comparison of core sampling and visual inspection for assessment of concrete sewer pipe condition

    Sewer systems are costly to construct and even more costly to replace, requiring proper asset management. Sewer asset management relies to a large extent on available information. In sewer systems where pipe corrosion is the dominant failure mechanism, visual inspection by closed circuit television (CCTV) and core sampling are among the methods mostly applied to assess sewer pipe condition. This ...

  • Managing metallic pipe: a white paper on the significant developments in metallic pipe inspection approaches, services and technologies

    Traditionally, many utilities have been managing their aging metallic pipelines using a replacement approach, which prioritizes a pipe based on its age and failure history. While in some cases, pipe replacement is both financially defensible and necessary, age and failure history alone do not provide enough data to determine if replacement of a pipeline is necessary. In fact, the U.S. ...

  • Industrial Pump Inspection

    An industrial pump service and remanufacturing company had two goals in mind when they went shopping for a borescope. First, the scope had to be easy to use and portable enough to take on service calls. Second, it had to have four-way camera articulation in order to steer navigate the pipes and small through-holes that are commonly found in industrial pump applications. They found exactly what ...

  • Importance of Inspecting Reservoirs

    Inspecting Reservoirs – what is the importance of them, why they are inspected, and how ROVs help pave the way for low-cost, regular maintenance. What is a Reservoir? Deriving from the French word réservoir meaning “storehouse,” a reservoir is exactly that – a storage place for water. More often than not, these bodies of water are ...

  • Quantitative pipe condition assessment with Pipe Penetrating Radar

    Abstract Pipe Penetrating Radar (PPR) is the underground in-pipe application of GPR, a non-destructive testing method that can detect defects and cavities within and outside mainline diameter (>18 in / 450mm) non-ferrous (reinforced concrete, vitrified clay, PVC, HDPE, etc.) pipes. The key advantage of PPR is the unique ability to map pipe wall thickness and deterioration including voids ...

  • Multi-sensor inspection robot shows benefits of pipe penetrating radar - Case Study

    Pipe penetrating radar (PPR), the in-pipe application of ground penetrating radar (GPR) is one of the most promising quantitative pipe condition assessment technologies to emerge in recent years. With most of the underground pipe infrastructure reaching the end of their design life there is a need to provide measurable data in order to establish the extent of rehabilitation required or the timing ...

  • Accepted Inspection Methods of Process Sewers.

    During the process of refining there is discharge of hazardous waste, this coupled with aging pipeline infrastructure creates a potential where waste can leak into the environment posing catastrophic threats to life. Federal agencies such as the EPA are beginning to penalize refineries that do not take necessary measures of disposing their waste. These refineries are subject to ...

  • Using pipeline integrity rule for pipeline inspections

    Historically, transportation of oil and gas by pipelines remains the safest and most economical mode compared with other modes. However, pipeline integrity does cause a concern to the public and environment along the pipeline route because it is ever present at the location for its useful life. U.S. pipeline failure incidents in the late ’90s accelerated the process of mandating pipeline ...

  • Expect The Unexpected During Inline Inspection Runs

    Over the past decade, several high profile oil and gas pipeline failures have shown that the consequences of a rupture can be extremely severe for both the environment and human life, and can result in billions of dollars in remediation costs. Because of all these negative consequences, governments have made it mandatory to conduct routine inspections on these assets to prevent catastrophic ...

  • 5 Considerations for Choosing Pipe Bursting

    Homeowners who encounter sewer, drain, and water line problems often dread repairs not just because of the expense, but the major disruptions that they expect. Excavation, torn up lawns, and days of going without water are associated with traditional methods of repair. Fortunately, technology has made it possible to assess and fix pipes with minimal disruption by using a technique called pipe ...
