RS TECHNIK Sleeve Pipe Rehabilitation Systems

When an entire section of pipe is in poor condition, the repair/rehabilitation is carried out by introducing a sleeve impregnated with resin.
It starts from a sleeve composed of a fabric with a flexible plastic coating on one side. The sleeve fabric is impregnated with a mixture of epoxy resins.
The impregnated sleeve, still flexible, is introduced by inversion or pulling into the pipe, remaining adapted and glued inside. The resins are then hardened or cured by recirculating hot water, steam or UV radiation.
This creates a new pipe inside the original pipe, without joints, which guarantees its resistance and tightness for decades. All this without exterior works, without ditches or excavations and in a minimum work time, just a few hours.

RS Maxliner®

For small diameters, interior networks and home connections. Portable equipment. Ease of working inside buildings, basements, terraces, etc.

The RS liner is tailored to the required length and both components (MaxPox ® resin and curing agent) are mixed with RS ProfiMix.

The epoxy mixture is introduced into the coating and distributed evenly with a calibration roller.

With the help of the RS LinerGun ® (reversing device) the impregnated liner is installed on the damaged pipe by means of compressed air. The coating is kept under pressure with air until the epoxy mixture has completely cured. Curing can be accelerated with hot water or steam.

When the liner has sealed inlets, it is possible to cut them open with the RS Cutter Milling Robot.

RS Cityliner®

For application in general sewer networks, drains, gas, ventilation ducts, etc.
Mobile equipment to carry out the entire process in the workplace.

In order to avoid air pockets, the coating is set under vacuum.
No air pockets = higher degree of strength and dense laminated structure.

The required amount of resin is preset and distributed evenly on the coating with the help of calibration rollers.

The epoxy resin mixture that has been produced without air in the mixing unit is filled directly from the static mixer into the coating.
The mixing process is permanently and automatically controlled and guarantees constant product quality. Water pressure overturns the impregnated coating with a calibration roller speed of up to one meter per minute. The coating is reversed.

The healing process is carried out by circulating hot water.
The house service connections are then opened quickly and accurately via RS cutters or robots.
After that, the home service connections are ready to work again.

For application in specific networks of pressure and water pipes.
Procedures and materials with certification for use in drinking water.

Sleeves and resins
Different types of sleeves depending on the conditions of the pipe to be rehabilitated and special epoxy resins for on-site preparation.

Ultraviolet
Specific systems for installing sleeves impregnated with resins for curing using ultraviolet radiation.
