Given the unique long-term structural retention of PipeGuard™ linings, the application thickness can be significantly reduced compared to other lining systems (cipp, grp and glass flake.. etc).

The lining thickness is dependent on the type of process piping, effluent parameters, loading and design life requirements of the system. Our tooling has the capability of applying 20 - 500 mils in one pass, making the application process extremely versatile. We have installed linings that range from 80+ mills for corrosion barriers in new piping, and 35+ mm linings for fully deteriorated restoration of in place pressure piping.

PipeGuard™ SL5 has superior abrasion resistance compared to alternative lining systems (grp, epoxy and glass flake). We have developed our own testing standard mandated by a private refiner in Singapore to establish the limitations of the SL5 lining system.

The testing was carried out by independent and 3rd party labs where the lining materials were subjected to velocities as high as 12 m/s with entrained abrasive media at various impingement angles to establish a viable design calculation for high velocity flow lines. The testing results concluded PipeGuard™ SL5 lining provides a significant life expectancy increase for systems that are subjected to particulate laden flows resulting in accelerated surface erosion.

PipeGuard™ linings commonly used for cooling water systems has sufficient elongation (above 10 %) which will remain unaffected from imposed displacements and deflection. In most scenarios the host pipe would fail first followed by the internal lining.

PipeGuard™ SL, TR and CL Series internal lining systems are certified for use in potable water systems.

All PipeGuard™ lining systems have a combined 20k hours of 3rd party testing by A2LA & ACLASS Singapore accredited Labs. Film thickness designs are calculated using these tested values. RestoLine has carried out rehabilitation contracts for fully deteriorated sewer force mains and water mains in Singapore and United States, all material testing requirements were fulfilled and exceeded the tender specifications.

Based on the pipeline condition PipeGuard™ SL6 can be designed as a class I – IV lining capable of withstanding all external loading, internal pressure and vacuum. The structural properties of SL6 exceed ASTM F1216 making it a viable rehabilitation method for fully deteriorated piping systems.

Class I – Provides no structural support, only acts as an internal corrosion barrier and improves water quality.
Class II – Resists external hydrostatic pressure from groundwater, bridges over holes and gaps in the host pipe, but not able to carry the full internal pressure independently, adheres to the interior surface of the host pipe.
Class III – Same as Class II except has sufficient thickness to resist buckling from external hydrostatic load or vacuum load and is not dependent on adherence to the host pipe wall.
Class IV – Independently capable of resisting external hydrostatic pressure from groundwater, and can handle the full internal pressure without support from the host pipe.

The PipeGuard™ lining system and tooling are programmatically monitored with a customized PLC, this ensures the tooling drive and spray rig operate in sync. The lining thickness will deviate from the design calculation by + 2 – 3 % in straight sections and up to +5% for short radius bends.

RestoLine’s spray lining systems accommodate 300 m and 600 m lining lengths, with a maximum lining distance of 1.2 km from an entry point.
Access pit dimensions are typically 2 m / 3 m for lining and inspection up to ⌀ 1000 mm.

RestoLine’s PipeGuard™ lining system has the smallest footprint in the trenchless industry:
Two 20 ft. containers are required for larger installations. For project sites with limited space and access constraints we have downsized mobile units that can be deployed to fit on an FPSO or even mobilized in the Jungle!
