Sleeve test certificates

  • EN489-1:2019 test certificates

    The test certificates state that connections with the sleeves from BRUGG Pipes:

    • Are waterproof
    • Are able to withstand the longitudinal forces caused by the longitudinal movement of the pipe in the ground
    • Are able to withstand radial forces and bending torques
    • Are able to withstand effects of temperatures and temperature fluctuations

Our sleeve systems for PREMANT

INDUCON fusion coupler

During the welding process, the casing pipe and the sleeve are heated and liquefied in a specific area. In this melted area, the materials fuse together in such a way that they cannot be broken apart again. The result is a durable, sealed weld. The INDUCON fusion coupler is the reliable solution that boasts exceptional strength and reliability. It is therefore also suitable for difficult ground conditions, as well as groundwater and pressing water.

EWELCON electrofusion coupler

HDPE plate

Fully prefabricated HDPE plate that can be installed immediately before welding. The connection boasts consistent quality, even under difficult or restricted installation conditions. HDPE plate with heating conductor and temperature sensor on the inside.

  • Applications

    The EWELCON electrofusion coupler creates a homogeneous connection between the casing pipe and sleeve plate so that even greater loads (e.g. the impact of temperature on the casing pipe) can be absorbed. A pipe is only as reliable and durable as its connecting components, which is why the sleeves play a key role in the design as a whole.


  • Thermal sensor system

    • Complies with specified reproducible welding parameters
    • Protects against thermal damage
    • Temperature-dependent power control for the CAW welding transformer

    The integrated thermal element transmits the temperature data for the PE melt to the welding transformer, which is controlled by a micro-processor. This ensures precision welding.


  • Wrapped sleeve

    • Protects against contamination from the building site
    • Copes with diameter tolerances and the oval shape of casing pipes
    • Can also be used on existing pipes (e.g. renovations)

    The EWELCON electrofusion coupler is wrapped around the pipe ends, compensating for the production tolerances of the casing pipes.


  • Reliable processing

    • Fully automatic welding process
    • Continuous process monitoring
    • Welding parameters achieved are checked and documented

    The welding transformer (CAW = computer-aided welding) controls the required power and determines the duration of the welding process automatically.
