Prestigious three-year Stockholm Water contract

Pipe joint specialist Viking Johnson has captured a prestigious contract with Stockholm Water, based on a comprehensive high quality product range and accurate tendering documentation

Negotiated by the Viking Johnson Swedish distributor Industri Belos, the contract is for the supply of UltraGrip and Large Diameter MaxiFit pipe couplings for the next three years, with an option for a further one year.

"This was a difficult contract to win because the incumbent supplier had held the contract for 12 years, but we were able to offer a high quality product at competitive market price levels - something that was recognised by our high points score in the Stockholm Water quality appendix," said Industri Belos managing director Gote Mattsson: "Another important consideration today is the way in which quotations are presented, so the support with the documentation that we had from our Viking Johnson colleagues in the UK was invaluable".

Although Viking Johnson has not been a regular supplier of Stockholm Water until now, it was already familiar with their technical requirements; in fact some of these influenced the re-engineering of the UltraGrip product some years ago, and triggered the recent addition of a 150mm x 175mm reducing coupling to the range.

UltraGrip pipe couplings, flange adaptors, Pecatadaptors and end caps are supplied complete with unique grippers that offer full end restraint to most pipeline materials equally effectively, to prevent axial movement due to the internal pressure in the pipeline.

This makes them particularly suitable for transitions between grey cast iron and PE when repairing or rehabilitating pipelines.

The convenience of UltraGrip is further enhanced by its exceptionally wide tolerance range of up to 44mm, which simplifies stockholding and installation alike.

In appropriate cases, pipes of different materials and diameters can be joined by a single UltraGrip coupling.

MaxiFit (which Stockholm Water will take in sizes up to DN600) is for repairing pipes of the same nominal bore when their exact outside diameter is unknown.

Uniquely, it can accommodate plain-ended pipes with variations in OD of up to 17mm, thus reducing the number of fittings that have to be held in stock and transported to site.

When it is bolted up, the MaxiFit exclusive 'slide easy' gasket provides maximum sealing pressure, even on the scored, pitted and corroded pipe surfaces that are often encountered during repair work.

MaxiFit is available in sizes from DN50 (2in) to DN300 (12in) and is suitable for use with steel, ductile iron, PVCu, cast iron and asbestos cement - in fact all conventional pipe materials except PE.

The range includes standard, long-sleeve and stepped couplings, flange adaptors, and variants to suit customer needs, such as stainless steel bolts and Nitrile gaskets.
