MARK

Fast-Line PlusTM is an innovative, fast-setting spray-applied resin for the in-situ lining of drinking water mains.

Fast-Line PlusTM has existing National governmental approvals for use in drinking water mains in the UK, France and the USA.
The product can be applied as either a low-build (1mm thick) or a high build (3-5mm thick) lining in a single pass, using conventional
spray lining equipment for fast setting resins, in lengths of up to 650’ (200 metres). Pipe diameters from 3” bore and upwards can be treated with Fast-Line PlusTM. The result is a durable, hard, corrosion resistant barrier layer over the whole of the pipe bore.

Fast-Line PlusTM can be used to resolve water quality and internal corrosion problems in distribution and trunk mains when applied as a low-build lining, and can additionally help eliminate and prevent mains leakage when applied as a high build lining.

Technical Aspects of Pressure Pipe Epoxy Spray Lining

Epoxy pipe lining resins are supplied as two-part solvent free systems consisting of resin or base material and hardener or activator. When properly mixed they will give a rapid cure, high-build, potable water certified material. The cured pipe lining material is inert and achieves pipe corrosion protection by providing an impermeable barrier, effectively separating the water from the pipe material, thereby preventing further corrosion.

The finished epoxy pipe coating is smooth and hard with excellent water resistance and hydraulic profile. The pipe lining will not impair the quality of potable water, nor will it affect the pH. The thin, smooth epoxy coating enhances pressurized pipe flow capacity of previously corroded water mains enabling operating pressure reduction to be readily achieved. The epoxy resin coatings are applied with the use of in-situ lining rigs equipped with heated materials storage tanks, umbilical hoses and application spray heads.

In the United Kingdom for example, there has been a complete transition from cement mortar pipe lining to the exclusive use of epoxy resin / polymeric pipe lining materials. The main reason for this change was the result of the development of water quality problems related to the lime composite of the cement mortar and the pH of soft water.

Our proprietary Triton epoxy spray lining process was designed for non-structural and semi-structural renewal of 3” and larger pressurized water pipes and is one of the least disruptive pipelining rehabilitation technologies available. The process applies a potable water certified epoxy to rehabilitate deteriorated and corrosion clogged pipes. At the AWWA standard 1 mm thickness, most typical pipe pinhole leaks are sealed, water main and fire suppression flow ratings restored and the prevention of future water pipe corrosion is ensured.

 

Epoxy and polyurea spray pipe lining rehabilitates pressurized water, fire suppression and industrial pipes ranging from 3? and larger in diameter. The lining process rehabilitates pipes by centrifugally spraying a solvent-free, protective lining onto the inner surface of the pipe. The cleaning and pipe lining process removes corrosion and tuberculation. It also restores carrying capacity as well as flow requirements of the pipe.

This tough trenchless process can rehabilitate 530 feet of tuberculated or reistricted pipes at one time, and protects against future corrosion and buildup without the cost and disruption of excavation and replacement.

We have used this proprietary spray lining technology to line more than 500,000 feet of pipe throughout North America over the past 10 years.

Recent research by AWWA Research Foundation concluded that deteriorated old pipes lined utilizing this process and technology can expect an additional 50 year design life.

 

Epoxy Pipe Lining of Drinking Water pipes Stops Pinhole Leaks, Low Pressure, Bad Flow, Lead Contamination and Brown Water

3 Easy Steps:

1. Open up opposite ends of rusted leaking pipes

2. Using air pressure and sand, sandblast away the oxidation deposits

3. Using air pressure, epoxy pipe coat the entire length of drinking water pipe

Eventually old copper potable water pipes in building oxidize (or corrode) and the pressurized water begins to leak out. So may have heard of slabs leaks or pipe leaks in walls, and to replace these pipes is very costly and invasive.

Epoxy pipe lining is an alternative that works very well and is usually cheaper than the total cost of pipe replacement, which includes the demolition and repair cost of all surfaces affected by the replacement.  It is used extensively in high rise buildings like hotels and apartment buildings that cannot afford the downtime or inconvenience of traditional excavation for pipe replacement. Here’s how it works:

First the pipes are sandblasted from the inside to remove all the old oxidation deposits. This is done by blowing air with entrained silica particles through the pipes. There is some “blowing” equipment upstream and “receiving” equipment downstream to capture the debris. Once the pipes are clean, air is again blown down the same pipe but this time along with an epoxy liquid that hardens in a few hours.

The epoxy used is the same food grade epoxy that you have seen on the inside of food cans, so it’s perfectly safe for consumption. This epoxy pipe lining is ideal for drinking water pipe lining, as it is very thin and very hard. But hard doesn’t necessarily make it strong, as it can crack under load-bearing applications, like under roads or wall footers. Generally epoxy pipe lining is used mainly in apartment, hotel and residential walls and floors, but not for sewer pipe relining.

But for situations where the pipe to be lined needs extra strength, regular drain lining pipe lining materials have to be used, such as the polyester and fiberglass felt impregnated with epoxy resin. These pipes are also usually of larger diameter, so the thickness of the liner has minimal effect on internal diameter reduction. This is called structural pipe lining (or just pipe lining).

Epoxy pipe lining is a pipe coating process that seals leaking pipes permanently. It is very popular in older cities like Washington DC, New York City, and Los Angeles. It prevents the need for repiping as it seals all copper pipe pinhole leaks from within the pipe. It also prevents lead from contaminating drinking water pipes from soldered pipe connections. Epoxy pipe rehabilitation is much less expensive than repiping and involves virtually no demolition in comparison. This type of pipe lining is usually used for water pipe leaks in pipes with 3/8”-4” in diameter.

When choosing the best method of water line repair, it is best to use the most tried and tested technology that fixes and then prevents pipe corrosion. Sometimes epoxy pipe lining is used to correct low water flow in potable water pipes. Low water flow is caused by the accumulation of corrosion deposits and scale from hard water. Hard water contains higher than usual levels of Calcium and Magnesium that combine with naturally occurring carbonates in the water to form calcium carbonate and magnesium carbonate that cause blocked pipes. Large buildings in Washington DC and New York City have extensive pipe corrosion requiring epoxy pipe coating. Corroding pipes result in discolored water, restricted water flow, deposits in glasses, pinhole leaks and lead water contamination.

Water line replacement the traditional excavation way is very invasive. It requires that all the leaking pipes be cut out of walls and floors, during which time there is no water supply. The ensuing mess has to be cleaned up of course, and in the meantime the repiping of drinking water lines means all tenants have no water supply, or restricted water flow, and for commercial application, production has to be shut down.

Epoxy pipe lining is used extensively where the structures are very old but also very valuable. In such instances repiping is not an option. Pipe corrosion over the years and thus leaking pipes make Washington DC and New York City ideal locations for epoxy pipe lining.

When choosing an epoxy pipe liner or epoxy pipe lining contractor, we recommend that you contact references which have had epoxy pipe rehabilitation. This type of trenchless piping has a long, steep and expensive learning curve. Not all epoxy pipe lining companies have the same epoxy pipe restoration experience. Pipe leak repairs do not have to be as invasive as replacing drinking water pipes by digging through concrete and walls.

If you have discolored drinking water coming out of your pipes, usually it is copper oxide imparting the color to the water. Pipe corrosion will be stopped completely by cured-in-place epoxy pipe lining. This type of trenchless water line replacement is so much better than repiping. Epoxy pipe coating methods have allowed tens of thousands of elderly retired folks in Florida to stay in their apartments while their pipes are being coated.

Trenchless water line replacement has some additional benefits:

  • Epoxy pipe repair eliminates the need asbestos abatement
  • Sections of the corroded copper pipe can be relined leaving other sections operable through the use of a temporary potable water bypass
  • Epoxy pipe restoration is much less noisy and allows facilities to continue with their business

Pipe repairs involving epoxy rehabilitation are the least invasive form of water pipe lining. Pipe corrosion and reduced water flow are alleviated permanently, as is discolored brown drinking water.

 

The fanciest equipment and the best resins are of little value if the contractor completing your project is not quality focused and experienced in the application process. While equipment and resins can be bought, experience is earned through years and miles of pipe rehabilitation. Experience is where Triton has no equal. With more footage of resious lined pipe than anyone in North America, you can have confidence in your project being successful.
