Technologies
PICA offers a wide range of technologies and inspection tools to address a variety of applications and customer needs.
NEAR FIELD TESTING (NFT) TOOLS
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 a higher level of confidence in the inspection results.
REMOTE FIELD TESTING (RFT) TOOLS (SEE SNAKE)
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 (PCCP). 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.
