Internal visual and sounding inspections require manned entry to the pipeline and dewatering of the pipeline. By combining the EM inspection data with the manned inspection, Pure’s engineering team can deliver an accurate report on the condition of the pipeline. Any pipes judged to be in a potentialstate of incipient failure will be immediately reported to the utility so replacement or rehabilitation can be performed while the pipe is out of service for the inspection.
The visual portion of the inspection consists of observing visible features and cracks that indicate potential distress; this requires experienced staff to know which cracks are normal and which are indicative of a problem. It also requires a thorough understanding of the width and length of cracks that are normally produced during the production of pipe as opposed to those that might indicate lack of prestressing wires, or distress, in the pipe.
The visual inspection also includes an examination of the joints, including the width of joints or theamount of pull the pipeline was subject to in order to maintain line and grade. All anomalies will be noted with the distance and location from known features.
The sounding portion of the inspection relies on impacting the interior surface of the pipe wall with a tapping rod and listening for hollow sounds that indicate delamination. Delamination is also an indication of a loss of prestressing wire in a pipe.
The Benefits of Visual & Sounding Inspections
Many wastewater utilities are faced with the difficult task of assessing their sewer force mains, Pure provides reliable pipeline inspection and assessment of force and gravity mains within operational constraints of most wastewater utilities.LEARN MORE
Assess & Address
In order to help utilities manage their aging assets, Pure has developed the Assess and Address® approach to maximize capital budgets and extend the useful life of pipelines. The approach focuses on assessing pipelines to identify specific problem areas that need renewal.LEARN MORE
Finite Element Analysis (FEA) is a process that estimates under what operating pressures a distressed pipe will fail.The process allows operators to determine the risk associated with keeping a distressed pipe section in service under various conditions.LEARN MORE
