Viking Johnson Secures Three-Year Stockholm Water Contract

Pipe joint specialist Viking Johnson has captured a contract with Stockholm Water from a long-established competitor, thanks to its comprehensive product range, superior quality and provision of accurate tendering documentation.

Negotiated by the company’s 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.

“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 Stockholm Water’s quality appendix,” said Industri Belos managing director Gote Mattsson.

“Another important consideration today is the way in which quotations are presented, so the support over 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 the company’s technical requirements; in fact some influenced the re-engineering of UltraGrip some years ago, and the recent addition of a 150mm x 175mm reducing coupling to the range.

Les raccords de canalisations UltraGrip, les adaptateurs à bride, les adaptateurs Pecat et les embouts sont fournis avec des dispositifs de serrage uniques qui assurent un blocage complet des extrémités sur la plupart des matériaux de canalisations, avec la même efficacité, afin d’empêcher tout mouvement axial dû à la pression interne de la canalisation. Cela les rend particulièrement adaptés aux transitions entre la fonte grise et le PE lors de la réparation ou de la réhabilitation de canalisations.

La facilité d'utilisation d'UltraGrip est encore renforcée par sa plage de tolérance exceptionnellement large, pouvant atteindre 44 mm, ce qui simplifie à la fois la gestion des stocks et l'installation. Dans certains cas, des tuyaux de matériaux et de diamètres différents peuvent être raccordés à l'aide d'un seul raccord UltraGrip.

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, MaxiFit’s 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 (2‰) to DN300 (12‰) 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 customers’ needs such as stainless steel bolts and Nitrile gaskets.
