PICA specializes in conducting high-resolution electromagnetic inspections of pressure pipes that are used in a variety of industries and applications. The quality of data collected from our company-designed tools is accurate, repeatable, and reliable.
PICA’s inspections enable water utilities to identify corrosion and other deficiencies in transmission and distribution system piping before leaks or larger, costlier failures occur.
Outages of cooling water pipelines and fire suppression system piping in processing plants and many other industrial, commercial, and educational facilities can be disruptive and costly. PICA’s tools provide an accurate picture of the condition of industrial pipes as small as 2-inch diameter, which allows for targeted repair and uninterrupted operation.
PICA uses both in-line and external inspection tools to identify the condition of wastewater force mains and treatment plant piping while keeping these critical lines in service. PICA’s inspections help to prevent high consequence spills, leaks, and failures.
Mining facilities rely on PICA’s in-line electromagnetic, CCTV, and leak detection tools to detect problems in firewater loops, slurry lines, brine disposal lines, water supply lines, and wastewater lines that could disrupt operations and have significant monetary impacts resulting from the unplanned shutdown of process units and/or the mine as a whole.
Nuclear and thermal power plants rely on cooling water and fire suppression systems to operate safely. PICA’s high-resolution inspection tools detect problem areas in cooling water pipelines and fire suppression piping systems to prevent incidents or failures that could shut down an entire operation.
Oil & Gas
Production pipelines carrying oil, gas, or disposal liquids often fail due to soil-side corrosion or internal corrosion pits. PICA’s autonomous in-line inspection tools are built to detect localized wall loss and more comprehensive pipe wall thinning with a high degree of accuracy, which allows for proactive spot repair of damaged pipe areas and minimal production downtime.
NEAR FIELD TOOLS
Near Field Testing (NFT) tools detect and quantify broken wires in embedded cylinder PCCP. During the electromagnetic (EM) inspection, PICA runs multiple frequencies simultaneously and employs several detectors on the NFT tool to increase resolution and accuracy of wire break data and provide our clients with higher confidence in the inspection results.
REMOTE FIELD TOOLS (SEE SNAKE)
Remote Field Testing (RFT) tools inspect metallic pipes for corrosion through internal liners and scale. This technique is well suited for cast iron pipe, ductile iron pipe, steel pipe, concrete cylinder (bar-wrapped) pipe, reinforced concrete cylinder pipe, and prestressed concrete cylinder pipe. PICA’s specialized RFT tools are known as See Snake tools.
HANDHELD EM & UT TOOLS
PICA offers a wide range of handheld electromagnetic (EM) scanning tools to detect and measure wall loss in metallic pipes. PICA also uses specialized versions of these tools that can inspect the condition of reinforcing bars and prestressing wires in concrete pressure pipes. Low-frequency EM tools can be used on either the inside or the outside of the pipe.
VISUAL INSPECTION TOOLS
Visual inspection technologies are extremely useful for documenting defects, such as offset joints, defective joint mortar, cracks or spalling of the mortar lining and much more. Visual inspection can be used as the primary inspection method, or it can be conducted along with an electromagnetic inspection to provide a more thorough understanding of the pipe’s condition. PICA’s CCTV, laser, and LiDAR tools offer exceptional image quality, even for large pipes.
Navigator is an in-line screening tool. These small diameter (3.25 inches) spheres travel freely within pipelines, screening for local leaks, gas pockets, elevation profile, and other important pipe information. Navigator is an easy-to-use and low cost tool that can be used in pipes from 6- 120 inches in diameter and made of any material.
