Latest product launches


Posted: Thursday 6th May 2010

Iron technology leader Saint-Gobain PAM UK has further extended its highly innovative family of small diameter water and sewer pipes through the addition of a range of 125mm products.

The Blutop™ range has generated strong interest across the industry since its launch last year and gives real choice to specifiers.

The 110mm product was launched in early 2009 and was joined by a 90mm range in the summer of last year. All Blutop™ products meet the performance requirements of the new version of BS EN 545 which is set to become the standard specification for pipes in the UK later this year.

Blutop™ draws on state-of-the-art technologies in both ductile iron pipe spinning and coating materials, combining the traditional values and long-term performance of ductile iron with the flexibility of plastics.

The unique combination of materials results in a system offering leak-free reliability, easy handling, reduced installation costs and high water quality even in contaminated ground, with outstanding durability and performance delivering lower installed and whole life costs over alternative systems. For example, compared against PE barrier pipe systems, Blutop™ material costs alone can be up to 50 per cent less.

Half the weight of traditional ductile iron pipes, Blutop™ pipes are easy to lay, require no special equipment and can be jointed manually through the new jointing system which includes a restraint option, removing the need for thrust blocks. Combining both strength and flexibility – up to 6° deflection at each joint - the Blutop™ system can be laid shallow or deep and is highly resistant to third party damage. The pipes have a unique DUCTAN™ interior lining which provides excellent water quality properties and an external coating similar to Saint-Gobain’s PAM NATURAL™ pipe system (high tech true alloy of zinc/ aluminium), making them suitable for use in a wide variety of ground conditions.
