PICA & 3M’s Holistic Approach for your Pipeline

September 26, 2013 Leave a comment

A common theme in this blog and in the water infracture industry on the whole, has been the costs of replacing aging pipelines. Research has shown that the traditional approach of  repair small leaks/breaks and replace the line when the repairs exceed a specified threshold may not be the optimal approach where 96% of pipelines are still in good working condition (“A Game Plan for Aging Water Infrastructure” AWWA 2010).

The Western Canada Water Conference and Exhibition was held in Edmonton last week.  PICA’s President, Dave Russell, along with Clint Jones, Product Developer at 3M Infrastructure Protection Division, took this opportunity to present a paper explaining the advantages of Direct Condition Assessment in combination with the right lining solution to rehabilitate the remaining 4%. Armed with the right information and the right solution, pipeline owners and operators can extend the life of their pipelines in a cost-effective manner.

PICA finds a hole in one!

May 31, 2013 1 comment

Last July, we posted a blog about inspecting 4,400 ft of 16-in ductile iron force main in the southern U.S. using PICA’s patented SeeSnake. The resulting condition assessment indicated that the first 550 ft of line was heavily corroded while the remaining line was in great shape. A report was written that provided the remaining wall thickness along with axial and clock positions for the three thinnest pitting regions in each pipe.

Last week, a dig was performed to confirm PICA’s assessment on one of the assessed pipes. PICA predicted a through hole (0% remaining wall) located 2.7 ft from the joint along with two other corroded regions approximately 6 ft from the joint. The excavated pipe contained exactly that.

Knowing that PICA’s technology provides direct condition assessment that works, the client can now make informed decisions regarding their pipeline.

PICA’s Bracelet Probe is successful in its first commercial application

October 16, 2012 1 comment

PICA recently completed field work using its new Bracelet Probe in Florida. A Bracelet Probe, manufactured by PICA’s sister company, Russell NDE Systems, is similar to the in-line SeeSnake tools used to inspect metallic pipeline. While the SeeSnake is an internally applied technology, the Bracelet Probe is applied externally and is appropriate for cast and ductile iron, bare pipe and for insulated, above-ground, steel pipe.

In Florida, PICA technicians inspected two sets of ductile iron pipe, 14″ and 20″ in diameter. Internal corrosion was found to be limited but there was some degree of external corrosion not immediately apparent from visual inspections due to the presence of graphitic corrosion. The graphite was later chipped out to confirm the inspected corrosion depth with a pit depth gauge. PICA’s results are currently being incorporated into the client’s Asset Management Plans.

PICA inspects 8″ and 12″ force mains in Southern California

August 28, 2012 Leave a comment

Inspecting FMs in SoCalPICA just delivered a final report for two force mains inspected in Southern California. The first line was 300 feet of 12-in ductile iron pipe and the second line was over 1,000 feet of 8-in ductile iron.

The two lines were selected by the client in order to obtain wall thickness measurements of the pipes as well as to assess the reliability and performance of the SeeSnake tools. Each run was accessed via manhole openings and contained multiple bends. The success of this job will allow the client to make proactive decisions about their infrastructure.

 

For more information about PICA’s services, please email us at info@picacorp.com or give us a call. We look forward to hearing from you!

PICA paper receives a 97% rating at NASTT No-Dig in TN.

June 22, 2012 Leave a comment

Many companies can offer an extensive list of the pros (many) and cons (few) of their technologies. No doubt, they are even true. Personally. I like to see case studies that give more practical information including a description of why the technology was needed, what pipeline or tool adaptations needed to be done to facilitate  using the technology, challenges faced (and hopefully overcome) and what the results were. And case studies usually provide a story-style narrative that makes it a better read than technology specifications.

Chris Garrett (PICA USA) and Ad Shatat (Russell NDE Systems) presented a paper at the NASTT No-Dig this year that scored in the top 1% of papers presented. Titled “NDE Techniques for Water and Wastewater Pipe Condition Assessment”, it offers two case studies:

  • 30 year old 12-in steel water main in Hong Kong
  • 20 year old 24-in ductile iron wastewater line in Missouri

Both lines were in sensitive areas, had fragile liners that could not be damaged and were inspected using PICA’s free-swimming SeeSnake RFT technologies.

Dacon and Russell/PICA sign co-operation agreement

December 9, 2011 Leave a comment

Dacon, a manufacturer of ultrasonic in-line inspection tools, and Russell NDE Systems, a manufacturer ofelectromagnetic in-line inspection tools for PICA, have signed a co-operation agreement through which each company may offer the other’s special “smart pigs” for applications that are appropriate.

Dacon toolRecent examples include:

  • Russell will provide one of its “High Lift-Off” RFT tools to inspect three 8-in, schedule 80 pipelines in Thailand. The lines have a cement mortar liner that is impossible for Dacon tools to penetrate. The lines will be cleaned by Dacon, who will also run the sizing pigs through the lines in preparation for the Russell tool.
  • Dacon will inspect a 24-in HDPE line located in New Caledonia for PICA. PICA’s tools can only inspect ferromagnetic lines (cast iron, ductile iron and steel), but the Dacon tool can inspect any material, except  HDPE liner in a steel pipe. In that case, the Dacon tool would be used to precisely measure the thickness of the liner and the Russell or PICA tool would be used to inspect the steel pipe. 

The ability for PICA, Russell and Dacon to share their tools and provide the best solution for individual applications in the water, waste water, mining, slurry and oil, and gas pipeline industries provides a more extensive solution set for our customers.
