Economical gas connection using Viega press technology

Economical gas connection using Viega press technology

When house builders decide on natural gas for heating, the installation of the house service connection comes to the foreground as a significant cost factor. The public utility of the town of Hamelin in northern Germany has been able to achieve a considerable reduction in these costs by the use of the press systems Geopress and Geopress K.

The burghers of Hamelin have always been innovative and cost-conscious. As early as 1861, the town on the banks of the river Weser supplemented its conventional oil street lamps with 27 high-tech gas lanterns. They were supplied with gas via subterranean pipelines.

Those responsible have kept a discerning eye on technological progress ever since. For instance in 2008, when they discovered Viega's newly developed press connecting technology Geopress for below-ground plastic pipelines. They subjected the new gunmetal press connectors to rigorous testing for a whole year. The field trials on sample sites showed: Laying below-ground PE-pipes using press connectors can be done more than twice as fast than with conventional welding.

These factors especially made the difference:

• In contrast to welding, pressing the pipe and the connector takes only seconds.
• In contrast to welding, the connecting can be done in bad weather such as rain and snow as well.
• Residual water in the pipelines does not play a role.
• There are no warming-up and cooling-down times as are needed for welding.
• There is no need for an electrical power supply for the welding gear.

In addition, Viega now also supplies press connectors of highly durable plastic for below-ground drinking water and gas supply lines – the Geopress K system. The experts from the Hamelin public utilities also carefully appraised this innovative connection technology – and came to the same positive conclusions.

The most important safety element in the Geopress K system is the extensive inner seal of the plastic connectors on a support body that requires no O-rings. This means that the ends of the pipes do not need to be either deburred or chamfered. Even external grooves make no difference.
