The Role of Non-Destructive Testing in Identifying Loss of Preload in PCCP-lines
Pipelines serve as lifelines for countless industries, enabling the transportation of vital resources across vast distances. Maintaining the safety and integrity of these pipelines is of the utmost importance. One significant threat that can compromise the integrity of Pre-Stressed Concrete Cylinder Pipes, in particular, is the loss of preload, which refers to the reduction of pressure containing capability of the pipe.
Are you aware of the condition of your PCCP (prestressed concrete cylinder pipe)? If not, PICA is here to help! At PICA, our team is committed to helping municipalities, industrial companies, and pipeline owners worldwide understand the condition of their pipelines. Our state-of-the-art in-line inspection tools can provide precise and accurate information regarding the condition of your pipelines. That way, you can make informed decisions regarding repairing, rehabilitation, or replacing your pipes. Keep reading to learn more about the tools PICA uses to inspect PCCP.
PCCP condition assessment services from PICA Corp.
Large-diameter prestressed concrete cylinder pipes (PCCP) are the most common means of transporting raw water, potable water and waste water over long distances in large volumes. Across North America, in particular, these types of pipelines make up critical infrastructure for municipalities and industrial companies alike. Despite being a highly robust and durable pipe type, PCCP lines still require routine condition assessments to ensure they are free from wire breaks and corrosion damage.
Pipeline Inspection and Condition Analysis: Can Your Lines Pass a "FFS" Inspection?
Do you know the last time your water mains, wastewater, raw water, fire water or other pipelines were inspected? Routine pipeline inspections are the best way to prevent the risk of unexpected failures and interruption of service and to determine if your pipeline is "FFS" (Fit for Service). By knowing the condition of your pipelines, and whether or not corrosion has taken root, you can make better-informed decisions regarding the maintenance and repair of your lines. At PICA Corp, our highly experienced team of technicians can assist you with analyzing the condition of your pipelines. Below we'll cover where pipeline corrosion comes from, and the many pipeline inspection tools PICA utilizes to determine the condition of your pipelines. Continue reading to find out more!
If your pipelines were to be inspected today, what would the inspection reveal? Pipelines fail due to corrosion, erosion, cracking and third party damage, all of which are invisible unless the pipes are uncovered and non-destructive testing (NDT) is performed on them. One very effective form of NDT that is performed from outside the pipe is electromagnetic (EM) testing. PICA's EM technology is embodied in its Bare Pipe Bracelet Probe (BP2). The BP is particularly effective in detecting ID corrosion on force mains caused by H2S damage.
