Clock Spring Unveils New Pipeline Corrosion Solution

Clock Spring Company, LP has launched Contour WA™, a composite solution featuring an engineered, bi-axial stitched e-glass tape impregnated with a water-activated polyurethane resin. The new product, which is designed for application on lines to 1,500 psi, repairs corrosion and mechanical damage on process piping in the downstream sector and is ideal for repairs involving complex geometries. It is designed for abrasion-resistant coatings and for horizontal directional drilling runs for pipes under roads and rivers and is suitable for use offshore.

“Controlling installation variables and increasing safety are first principles in Clock Spring’s R&D program,” said Clock Spring Chief Executive Officer Matt Boucher. “While other water-activated pipe repair products are available on the market, none offer the full solution provided by Clock Spring Contour WA, which is installed following a precise process that reduces HSE risks.”

The Contour WA solution includes several innovative elements to provide a controlled installation that delivers increased safety and sustainability. The product is packaged with the Clock Spring SprayerTM, a measured dispenser that ensures an accurate and consistent water-to-resin ratio to guarantee proper curing and a quality repair. Meticulous control during installation of Contour WA prevents over-wetting, eliminating wastewater and the associated potential for EPA violations, unlike the processes used for competing products, which result in excess water dripping off the pipe as contaminated wastewater.

The solution also employs a wet film thickness meter to ensure the proper amount of primer is applied prior to installation. Once the Contour WA is in place, Clock Spring AnchorPlyTM secures the installed repair to facilitate curing. AnchorPly requires no sanding or perforating prior to the final UV coating process, which means there is no dust produced in the installation process that potentially could be inhaled by the installer. And by eliminating the commonly used “porcupine” perforation tool, Clock Spring removes dangerous tool handling by the installer. When the Contour WA installation is complete, a durometer hardness gauge, included in the Clock Spring QC kit, allows installers to verify fibers have cured properly.

“Clock Spring is driving an increased level of sophistication in product development in the composite pipeline repair industry,” Boucher added. “No longer do customers have to accept inflexible options such as cement or welded sleeves. Composite technology offers a safe alternative to pipeline repair and maintenance.”
