Non-destructive rehabilitation and repair of pipes

The non-destructible repair and rehabilitation of pipelines is a technology that does not require that old pipes be replaced. Instead, they can be rehabilitated through the use of a sleeve of new pipe inserted along the route of the old pipe (host pipe) with minimum disturbance to the environment and surroundings.

This method upgrades today’s conventional methods and makes it possible to rehabilitate and renew existing pipes even in locations where repair or replacement busing regular methods is impossible. (Beneath railway tracks, under bridges, busy road junctions, in a crowded urban environment and more).

Advantages of the technology:

Minimum disturbance to the environment and surroundings (traffic, protected areas, noise nuisance etc.).

Reduction in noise and environmentally polluting emissions.

Work is completed very quickly allowing for a fast return to regularity.

Reduced usage of machinery.

Significant improvement in the flow of liquids – lower friction ratio.

Non-destructive Rehabilitation and Repair of Pipelines

Non-destructive rehabilitation of pipelines is technology that rehabilitates existing pipes by the insertion of a sleeve of new pipe into the old pipe (host pipe) rather than replacing it in its entirety. Work is completed with minimum disturbance to the environment and surroundings.

This method upgrades today’s conventional methods and makes it possible to rehabilitate and renew existing pipes even in locations where repair or replacement busing regular methods is impossible. (Beneath railway tracks, under bridges, busy road junctions, in a crowded urban environment and more).

Advantages of the technology:

> Minimum disturbance to the environment and surroundings (traffic, protected areas, noise nuisance etc.).

> Reduction in noise and environmentally polluting emissions.

> Work is completed very quickly allowing for a fast return to regularity.

> Reduced usage of machinery.

> Significant improvement in the flow of liquids – lower friction ratio.

Primus Line

Primus Line is innovating technology for rehabilitating pipelines without having to excavate pressure pipes for the movement of materials such as water, gas and oil.

The process is based on a flexible pipe under high pressure and connection technologies developed especially for this system.

Primus Line technology is suitable for a variety of liquids in the water field and has been award exclusive approval for the pumping of drinking water in Israel as it meets Israeli Standard 5452 as well as other international standards.

The especially smooth, internal wall of the pipe, the ideal flow characteristics and the optimum suitability of the system to handle high, intermediate and low pressure, make Primus Line the economic choice for the rehabilitation of aging pipelines. Water authorities and water networks across the globe already enjoy the benefits of sustainable and reliable operations.

Flow Liner – Neofit

Neofit is patented technology for coating pipes developed by Flow Line, a company that has been active around the globe for more than 40 years. The company provides innovative solutions to homeowners, industry and local authorities.

Pipe rehabilitation using Neofit make possible fast installation using a 0.3 mm thick “guest” pipe that is inserted into the existing pipe and the use of a patented system that causes the inserted pipe to cling to the sides of the old pipe.    Thus, it is possible to totally rehabilitate the old pipe without any significant decrease in the diameter of the old pipe. This technology also halt corrosion and is a solution for leakage problems.

The technology is approved for use with drinking water in Israel and the world.
