Pipevision Products Inc. and FAST Pipe Lining Inc. combined have sold over 1,500,000 (1.5 million) CIPP pipe liners and over 2,000,000 (two million) pipes relined by our CIPP lining crew for over 25 years, tackling the most prevalent in gravity sewer systems, pressure pipes, sanitary, storm drains and culverts, water mains, gas mains, hydro-carbon lining and more. Our CIPP liners are designed for pipes from 4" to 144" inches in diameter and are the smart solution for your sewer system pipe rehabilitation. The CIPP liner installed consists of a resin-saturated into a high-quality felt tube that is used for mainline to lateral connections, lateral lining, mainline repair, and manhole rehabilitation. The CIPP liner is inserted into the entrance of an existing pipeline then uses water or steam pressure to turn it inside out. Inverting the tube positions the resin on the outside. The hot water or steam circulates through the tube to cure the resin, sealing the felt liner tightly to the inside of the host pipe. Now turned outside-in, the liner’s polyurethane coating forms a smooth, strong, and long-lasting pipe-within-a-pipe. Because of the cured-in-place materials seamlessly molded into the host pipe, preventing infiltration and exfiltration, restoring the structural integrity of the pipeline, and eliminating weakening joints. This installation is trenchless, allowing communities to avoid the high cost, hassle, and risk of open-trench construction in populated areas.
Lining vs. Pipe Replacement
There are certain circumstances when CIPP solutions are appropriate. Many large underground waste and sewer lines are expensive to excavate and replace, and CIPP solutions can be very beneficial in these circumstances. Likewise, for larger drain and sewer pipes buried under concrete slabs, access can also be very expensive, making CIPP a more cost-effective solution than replacement.
Some may suggest pipe replacement or pipe bursting would be considered a better process. Here's how it works with pipe bursting, there is no loss of internal diameter for your pipes. The replacement pipe being dragged into place by the bursting head will be the same size as the original pipe. This means that there will be less risk of restricting water flow in the pipe after the operation is finished. The old pipe is being destroyed and replaced, the condition of the old pipe has almost no effect on the replacement process. Unless the pipe is completely collapsed and filled in (blocking the path of the chain dragging the bursting head), damage to the pipe wall will not affect the replacement process.
CONCLUSION: With CIPP lining, buildup in the pipe walls can further reduce the diameter of the new lining—meaning the pipe needs to be cleaned of such buildup prior to lining it. One advantage of CIPP lining over pipe bursting is that the old pipe can act as an extra layer of protection for the new lining. Also, for simple problems like cracks and small gaps, CIPP lining may be less costly than pipe bursting. We make the best suggestions for your pipelining issues and the decision is all yours.
Pipe Capacity Restoration effectively restore pipes to their original inside diameter. This process is completed before applying an epoxy coating or installing a structural liner within the pipe. Buildup, calcification, and subsequent corrosion can damage pipe functions and obstruct water flow, leading to long-term damage, reduced performance, and many other complications.
Pipevision Products Inc. and FAST Pipe Lining Inc. have a variety of technologies available to solve the pervasive problem of pipe corrosion. Pipe capacity restoration includes the use of hydro, mechanical, and pneumatic equipment to clean out existing piping systems. For many piping restoration projects, this is imperative to the process in order to ensure a successful installation and long-lasting results. We also do Hydro Carbon Lining. Ask us about how we can help you with your project on pipe restoration.
When CIPP Lining Is Not An Option:
> When an existing pipe has severe pipe deflection (loss of ovality)
> Where there is a collapse unless a localized pipe repair is performed.
> Where the requirement is to increase existing pipe capacity.
> Where chemicals can erode or dissolve CIPP liner material.
> Where pipe effluent temperatures can be abnormally high.
CIPP STEAM OR WATER CURING VS CIPP UV CURING
There are articles circulating that "Even though you will hear that CIPP UV curing is a major force in Europe and that UV CIPP technology is generating considerable interest in the U.S, providing additional options for the ever-growing CIPP market. UV-cured CIPP is just one more step in the evolution of CIPP in the United States where water/steam cured liners have been used successfully for years." That sounds good, right. But, not only is UV Cured CIPP extremely expensive, the truth is not mentioned that the main problem in a UV Cured liner is that the cured liner shrinks to about 1% and roots can migrate to the ends of the liner. Not forgetting that the main problem is water in pipes. This process does not like water! All water mains, laterals, and sewer lines to manholes have some form of fluid. There are some UV Systems that work but they have not revolutionized the process to the point of the longevity of a CIPP Steam or Water Cured-In-Place-Pipe that has proven its durability for over a quarter of a century.
Looking back at recent CIPP history, felt CIPP lining manufacturers and sanitary sewer service providers and contractors routinely used styrene-based resin. Since then, there are many optional felt CIPP sewer liners that have Styrene-free resin. Specific rehabilitation locations may dictate where specific resins can or cannot be used. While standards for styrene use may become stricter, there does not appear to be any immediate actions pending that would ban or prevent the use of styrene-based resins.
PROS & CONS of UV Curing
PROS for UV CIPP:
• Nice, clean process
• Minimal styrene emissions
• No cure water or steam condensate discharge
• Short curing times
CONS for UV CIPP:
• Size of pipes that can be rehabilitated is limited
• Cannot cure thick wall tubes without adding an initiator for heat cure which reduces wet out tube life
• Short cure times may not be shorter than some steam cure processes
The final decision is yours. Pipevision Products and FAST Pipe Lining have been doing the CIPP Steam or Water Curing for over 25 years. When properly installed, there have been no lining gaps or roots migrating to the ends of the liner. We have installed over a million CIPP liners with various resins, using the steam and water curing process, and have not been contacted to date to redo a single liner successfully installed. The quick and clean process is not necessarily the best route. Let's face it that in this industry we have to get down and dirty so which route would you choose, the longevity of the liner installed or how clean the initial process is?
With Pipevision Products all pipes rehabilitation are done right, from start to finish.
