As buildings and their plumbing systems age, water quality and dependability begin to deteriorate. Property managers face increased maintenance costs as they deal with problems such as corroded water pipes, pinhole leaks, insufficient flow and poor water quality
Traditional answers are to spot repair by removing and replacing the damaged area of the piping system or to re-pipe the entire building. These repair methods create additional work and expense since access to pipes is gained only through the opening of walls and ceilings.
Pipe Shield utilizes the benefits of compressed air technology to apply an ANSI-NSF 61 Certified Epoxy coating to the inside surface of piping networks (1/2″ and larger). Piping systems for domestic hot and cold water, heating and process piping are rehabilitated “in place” without the aftermath of costly renovation work to walls, ceilings and floors associated with conventional repair methods. The epoxy coating is applied after the existing pipe is dried and cleaned by the use of compressed air and an ANSI-NSF 61 Certified abrasive material.
Quality assurance is performed by using fibre optic video scope camera systems capable of passing through a 3/8″ pipe at all stages of the process. The Pipe Shield process is a quick, clean and economical solution to restore aged piping systems to a better-than-new performance and condition.
PIPE SHIELD AN500™
Pipe Shield AN500 is a specially formulated epoxy resin developed for Pipe Shield for use in small diameter hot and cold water pipelines. The epoxy coating is a product of highly advanced resin technology and is certified to ANSI-NSF Standard 61. After application, the epoxy coating creates an impermeable barrier between the water and the pipe material thereby preventing any further internal corrosion / erosion.
The Pipe Shield coating has a smooth, hard gloss finish with excellent water resistance and hydraulic profile. The thin, resin coating enhances flow capacity of previously corroded piping enabling pressure reduction to be achieved. Pipe Shield products are applied with specialized high tech equipment and specially trained plumbing personnel.
“Computer Guided for Maximum Consistency”
We have developed a software / simulation program that is used to calculate the lining parameters. The software program ensures that the consistency of lining thickness, uniformity and coverage is obtained. Our epoxy and application parameters are specifically designed to provide the “hoop strength” to adequately rehabilitate worn, corroded, eroded and leaking piping, unlike other systems that have been designed to provide a “barrier” coating on new piping or piping with at least 50% remaining wall thickness.
With Pipe Shield, our expert team will be able to repair your piping system one riser at a time, which means that the remaining risers in the building will be able to stay active and continue providing water to your entire building.
Step #1: Initial Site Visit and System Analysis
Identify problems such as pinholes, corrosion, discoloured water, and the reduction of cross section area.
Step #2: System Preparation
Plumbing zones are to be determined for the schedule of work. Water from the riser is drained, valves are closed and fixtures are temporarily disconnected from the water supply. Pipe outlets are connected to the air distribution system.
Step #3: Drying
One riser system is isolated at a time, keeping the water on in other risers. The average downtime per riser is about 10 hours. Hot, filtered, dry air is introduced into the riser with the use of a highly specialized compressor. The inside of the pipe is dried thoroughly.
Step #4: Cleaning
Dried pipes are cleaned using a corundum mixture applied with hot air. The movement of the cleaning agent through the pipe removes the corrosion and transports it to an exit opening in the pipe where it is collected and disposed of. The waste product is non-toxic and environmentally friendly. The result is a clean, rust free, “sharp tooth” surface inside the pipe ready for proper bonding of the epoxy.
Step #5: Coating
The Pipe Shield coating is applied in sections, under compressed air, to the inside wall of the pipe, forming a durable, resin shell with seamless adhesion. The new resin coating within the existing pipe will protect the water system permanently from future corrosion.
Step #6: Reinstatement
The water supply is reconnected and complete system checks are performed.
Pipe Shield lining systems will restore the existing pipe to compete against a replacement pipe with the following benefits:
- Completely Non-Toxic And Safe – Our ANSI-NSF Standard 61certified epoxy is 100% BPA free and completely safe for long term use.
- Ontario Building Code Approved
- Alberta Building Code Approved
- Hydraulic Capacity – Improved water flow in your system thus reducing electrical requirements for pumping systems (30 to 40%)
- Longevity – New pipes start to deteriorate the moment the water is turned on. Epoxy lined pipes protect from future corrosion or pinhole leaks indefinitely. Epoxy coatings are 44.4-times harder than type “L” copper pipe.
- Maintenance – Epoxy resin coating creates a permanent protective shield between water contact and the inside surface of the pipe. Therefore no more pinholes with copper pipes or the rapid growth of tuberculation in iron pipes.
- Water Quality – No further leaching of lead, galvanized or copper into the water stream resulting in improved drinking water quality.
Pipe Shield is also a certified green technology that has a significant impact on 4 of the 5 objectives specified by the Ministry of Research and Innovation as follows:
Reduces greenhouse gases by not having to manufacture new pipe, fittings, solder, pastes, insulation, wall repair materials, and recycling of old piping;
Reduces debris going to landfill including drywall, old insulation and very toxic fire stopping materials;
Results in cleaner water by reducing heavy metal content in the waste water flowing to waste water treatment plants, that cannot be removed and end up in our lakes and streams; and
Reduces electricity consumption as the smoother inside pipe wall reduces friction and pumping energy.
Over the Lifetime of the Product, Pipe Shield Saves Hundreds of Thousands Compare to Pipe Replacement, Here’s How:
– No additional costs for plastering and painting.
– Restoration without cost of waste disposal associated with conventional re-piping.
– Property managers save substantial time, money and disruption compared to traditional re-piping remedies.
– Long term savings due to reduced maintenance cost.
