Allows for application in non-circular cross-sections

Lining and Coating Terminations:

RestoLine designs and manufactures multiple termination options for our spray applied lining and coating installations. The termination method selected is dependent upon the substrate and mating interface between the pipe sections or spools. Once installed, the lining termination will prevent coating delamination in the substrate and crevice corrosion from occurring at the flange faces. Our spray lining termination systems have been lab tested up to 12 m/s and on-site installation with up to 9 m/s velocities without failure.

(SAG) GeoLining

GeoPolymer Lining System:

PipeGuard™ GP series is a geopolymer mortar system that provides an impermeable monolithic lining with non-leaching antimicrobial properties. The anti-corrosive chemistry of the lining makes it an ideal low cost trenchless solution (CIPP, SPR Alternative) for larger diameter gravity systems that undergo constant attack from high concentrations of h2s.

PipeGuard™ GP Lining:

Our PipeGuard™ GP series lining is reinforced with micro-fiber fillers, upon installation the existing storm or sewer pipe will be structurally rehabilitated with mechanical properties exceeding ASTM F1216. The lining installation prevents chemical attack, sewer overflows, excessive infiltration and associated sink holes from occurring.

GP Series Benefits:

Spray applied in high humidity and wet substrates

Forms a crystalline bond, higher resistance to acids

Multi pass lining application, layers fuse together

Fast curing properties allow for rapid reinstatement

High compressive, flexural, and tensile strength

Monolithic, structural lining with low permeability

Spray Applied Cementitious Linings:

RestoLine’s PipeGuard™ CL Series range from standard portland mortar to modified hybrids for added strength and fused or stand-alone calcium aluminate to enhance chemical and corrosion resistance. Our cementitious lining systems can be robotically applied with a spin cast method (up to 500 mm) or spray applied (1.5 m+) for tunnel ⌀‘s.

(ILI) Inspection Systems

RestoLine Inspection Centralizer

Tooling Capabilities:

RestoLine’s patented delivery method targets unpiggable pipelines ranging in ⌀’s (200 mm – 1.5 m) with lengths up to 600 m from a single entry point. The robotic tooling is configured with NDE Sensors that relay real-time information, allowing for rapid assessment of the internal pipeline condition; Tooling configured with multiple sensors eliminate multi-pass inspections, allowing for complete assessment and data collection in one single pass.

Easily adapts to ⌀ reductions and inconsistencies

Tooling allows for small access and no excavations

Lining distance from entry point: 600 m

Navigates vertical sections & tight 90° ells

Laser Profiling

All of the measurement data is transferred from the on-board centralizer PC to the control unit. This data is used to calculate the inner profile of the pipe, measure section loss, and create a graphic display for review at the control unit.

Laser Measurement

Inspection systems for pipes >150 mm include a laser measurement sensor to identify internal defects & corrosion. With the laser displacement sensor, it is possible to measure internal defects with micron accuracy at long distances.

High Res PTZ Camera

The centralizer’s inspection head provides high definition video feed. The head has pan and tilt functions and an integrated color camera. With the high quality resolution, 8x optical zoom, manual and automatic focusing.

Ultrasonic Inspection

The ultrasonic inspection head has rotating sensor probes. It can measure both the pipe wall and lining thickness with an accuracy of .18 mm. The signals are converted by the on-board PC in the electronics module.

Inspection Sensors Capability and Benefits:

EMAT – NON contact UT for crack inspection

Inspect entire pipe section with ili opposed to OD examination (cost reduction)

Shear Wave – determine pipe wall thickness

Compiling pipeline assessment information for integrity verification process

Eddy Current – internal condition assessment

Eliminate system downtime utilizing our ILI) solutions (options for ILI during operation)

Crack Inspection for Unpigabble Lines:

Facility piping is generally not designed with piggability as a requirement. Many unpiggable conditions exist with navigability that requires 1D back to back bends, mitered and dual diameter inspection capabilities that are not possible with conventional ILI methods (pigging). RestoLine’s tethered (ILI) system can navigate these complex geometries and require no launching facility in order to insert the tooling.

Pump Stations

Pump Stations that connect mainline to and from the pipe units are often above ground but have buried portions. These piping sections range in size with diameter inconsistencies and a large amount of bends dependent upon the layout design.

Compressor Stations

Compressor stations have piping that connects the mainline to the compressors. But generally there is inline equipment such as scrubbers placed before the compressor and after the coolers. These also range in diameter with a large number of bends.

Tank Farms

Tank Farms have interconnected pipe that is normally above ground with longer lengths than stations. The diameter of the piping will normally vary but typically will be similar to the mainline diameters and closely match the process flow rates.
