PRFV Liners can install 130 meters of liners in less than 24 hours
Inspection of sewage or storm pipes is performed by an adaptable robotic device with a high resolution camera.
PRVF Liners rehabilitates rainwater, sewer, and drainage pipes using liners and plastic (polyurethane) reinforced fiberglass (GRP).
Record timing rehabilitation
Once the pipeline is inspected and cleaned, the rehabilitation process begins. It takes about 5 hours, depending on their diameter and length. After the rehabilitation is completed, the pipeline is ready to be used again.
Video inspection provides information about the conditions inside the pipe. Through video inspection it is confirmed that the pipeline is completely clean and no is liquid pouring inside. The rehabilitation process is then ready to be initiated.
The liner is introduced through the inlet pipe or manhole and inserted into the pipe to be rehabilitated.
Once the liners are in position, plugs are placed to allow inflation with compressed air until the liners occupy the entire diameter of the pipe. The liner is calibrated with compressed air until it is adapted to the wall of the pipe.
A train of lighting equipment is then inserted into the pipeline and the UV light curation process starts. The process is performed by a fully computerized system that allows the recording of temperature, feed-rate and pressure in real time. The entire procedure is documented and delivered to the customer in video documentation. The equipment of ultraviolet (UV) curing / polymerized therein is performed, so the product is cured and sealed liners. Using the UV light equipment, the interior of the pipe is cured and polymerized. Now the liner handling has been hardened and sealed.
Because the technique allows complete work in very short time margins, the liners can be installed faster than any other existing system.
Liners return structural integrity to damaged pipes without breaking the roadway or causing inconveniences to the surrounding area.
Because of its higher modulus of elasticity and resistance to bending and compression, reinforced fiberglass polyurethane liners are designed to provide superior performance in comparison to any other coated fiberglass rehabilitation system. Also, their average 70-year lifespan makes them ideal to rehabilitate pipes with high static and dynamic load, ranging from 150 mm to 1500 mm in diameter.
While curing with ultraviolet light instead of hot water or steam, PRFV LINERS avoids any risk of wastewater contamination in the air or water system.
Because of different dimensions, profiles and special requirements, depending on liquid flowing and circulating inside, all pipes are different. PRFV LINERS system rehabilitates circular, ovoid, and box-like pipes, with diameters ranging from 150 mm to 1500 mm.
