Product Information
CaseX Steel Spacer/Roller Ring
Properties
- Easy pipe installation by reducing friction between the carrier pipe and the casing pipe
- Provide support for the carrier pipe
- Act as spacers between carrier pipe and casing pipe.
The carrier pipe can be placed in concetric or eccentric positions in casing pipe - Ensure electrical isolation between carrier pipe(s) and casing pipe
Fields of application
Often it is not possible to lay pipes in open ditches. For example, for rail or raod crossings it is first necessary to drive casings underground.
By using steel spacers or roller rings the carrier pipe can be inserted into the casing pipe.
Description
Each ring consists of two half-shells, which are clamped together by hexagonal bolts and nuts. The CaseX steel spacers/roller rings are manufactured individually.
Notes
- Different skid heights for the upper and lower half shells allow any position of the carrier pipe in the outer casing. For longer distances, if necessary with guide rail (anti-twist device).
KuRRi® Polymer Roller Ring
Properties
- The basic disc is made of polyethylene with corresponding drill holes and gaps for carrier pipes.
The drill holes are slightly bigger than the outside diameter of the respective carrier pipes - Possible additional openings (as required), which facilitate a better flow of filling material
- Wheels made of Polyamide with bolted steel axle (stainless steel on request)
- Connection of various polymer roller rings to each other with pull rods
- Guide rail to prevent twisting (if necessary) which will be fixed in casing pipe by customer. The working space in the tunnels, galleries or pipe penetrations must be sufficient according to german standard DGUV
Description
In case of socket connections of the carrier pipes (e.g. electrofusion sockets), the sockets can be placed so they are in contact with the polymer roller ring (depending on available space). This prevents axial displacements of the carrier pipes in the feedthrough direction.
Notes
- If a steel winch is required for longer lengths, it can be easily fixed on the pull rods without the use of special tools
Fields of application
The polymer roller rings are suitable for the insertion of several cable pipes in relation to plastic pipelines in the field of electricity, gas and water supply.
Technical Information
Steel roller ring with holding clamp for socket joints
This steel roller ring also has two (or more) clamps. The additional clamps are located on the main holding
clamp.
Individual steel solutions
In the wide field of protective pipe laying, there are applications where plastic spacers and KuRRi can no longer meet the requirements
Examples:
- Multiple pipes in exact defined position
- Support for long distances
- Permanent pipe movement
- High temperature
- Heavy weight
- Integrated tensile protection
- Hanging constructions
