In order to simplify the installation of house connections, Viega is advertising two new complete systems that are intended to make the effort involved in installing tapping fittings and welding plastic pipes using press technology a thing of the past:
- the „Geopress K“ system (recognisable by the blue clamping rings), approved for use with drinking water (the EPDM sealing element complies with the Federal Environment Agency's elastomer guidelines).
- the „Geopress K Gas“ press connectors with HNBR sealing element (recognisable by the yellow clamping rings), approved for natural gas and liquefied gases (in accordance with DVGW worksheet G 260) and also H2-ready (i.e. suitable for the transmission of hydrogen and natural gas/hydrogen mixtures in accordance with the test regulations of the DBI Gas Technology Institute).
The handling of both systems is described by the manufacturer as „identical and simple“: „Robust press connectors made of glass fibre-reinforced plastic for a wide variety of PE pipes of class SDR 11 are pressed with the battery-operated 'press guns' from Viega.“
Weather-independent, time-saving and safe use
Where weather protection in the pipe trench is associated with a certain amount of effort, press connections can be produced regardless of weather conditions, in cold, wet, rain or snow. In contrast to welding, water running on or cooling times also play no role with press technology.
According to Viega, the new press connectors seal securely by means of a support body on the inside of the pipe. The second safety feature described by the manufacturer is the SC-Contur of the connectors („forced leak tightness in the unpressed state“): „If the fitter overlooks an unpressed connection, it can be clearly recognised during the final pressure test at the latest. However, in order to rule out such sources of error as far as possible, the blue or yellow clamping ring on the connector also signals successful crimping. The clamping ring, in conjunction with the tooth contour on the support body, also ensures that the connectors are longitudinally force-fit, as verified by the so-called excavator test. The high-strength, glass fibre-reinforced plastic from which the connectors and tapping fittings are made provides even greater mechanical resistance.“
