Spray-In-Place Pipe Lining (SIPP)

About Trenchless Spray-in-Place-Pipe Lining (SIPP)

Spray-in-place pipe (SIPP) is an advanced trenchless technology for pipe repair that utilizes cutting-edge robotics to apply an epoxy coating within an existing pipe. The process, also referred to as spray-in-place pipe lining, employs a robotic system with a precision spray head to ensure uniform and durable pipe coating. This pipe rehabilitation solution eliminates the need for trenching or significant excavation, making it a cost-effective and efficient alternative to traditional pipe replacement methods.

Once cured, the epoxy lining seals the host pipe, preventing leaks, contamination, and future corrosion while improving flow capacity. SIPP is highly versatile and works on a range of pipe diameters, from small diameter pipes of 4 inches to larger pipes up to 36 inches. This makes it ideal for applications in water mains, sewer lines, and systems carrying potable water.

Advantages of Trenchless Epoxy Pipe Lining

Cost Savings: SIPP delivers an estimated 40% in cost savings compared to direct pipe replacement.

Minimized Disruption: This trenchless pipe method ensures minimal disruption to the site, with no digging required. A truly efficient spray in place solution.

Enhanced Performance: Improves system efficiency and extends the lifespan of pipelines by preventing buildup and leaks.

Corrosion Protection: Spray in place solutions shields pipes from future corrosion and degradation, ensuring longer service life.

Spray-in-Place Pipe Lining Process

Before

A three-foot section of the host pipe is removed to create access points for the robotic equipment. A thorough evaluation using CCTV inspection ensures the exact section of the damaged pipe is identified for rehabilitation.

Post Surface Prep

The pipe’s interior is cleaned using hydro-jetting to remove debris and contaminants, creating a smooth and dry surface. This step is critical for proper adhesion of the epoxy lining. Another CCTV inspection follows to confirm the surface is ready for application and to identify any necessary external repairs.

Liner Installed

The spray head applies the epoxy coating evenly across the pipe interior. Once the epoxy cures, a final CCTV inspection ensures that the pipe coating is seamless and pinhole-free. The removed sections at the access points are then reassembled, completing the process.

Equipment for SIPP

The advanced robotic spray lining equipment is capable of applying various lining solutions, including epoxy, polyurea, and polyurethane. Designed for both content-quality restoration and semi-structural pipeline repair, it accommodates pipe diameters ranging from 4 inches to 36 inches.
