Blutop™ Gets Installation Back on Track

Posted: Wednesday 3rd February 2010

Iron technology leader Saint-Gobain PAM UK’s Blutop™ small diameter ductile iron pipe range was used by Wessex Water recently during a major project on a residential estate.

The Gribb Farm project required 216m of Blutop™ 110mm OD pipe to be laid to replace a 50-year-old system which had begun to leak, regularly interrupting supply. Due to necessary road closures and demand from local properties, Wessex Water had to work to a tight schedule which was compromised in the early stages due to difficulties in excavating the heavy rock.

Despite the difficult conditions, the Blutop™ installation phase brought the project back on schedule. Blutop™ was originally selected for its strength, flexibility and ability to be installed quickly due to its reduced weight. Pipe layers found that the lightweight Blutop™ could be lifted and manoeuvred into place manually, with no need for machinery. Additionally, the easy fit gaskets and push-fit pipe system allowed for quicker installation once in position.

A further benefit of Blutop™ was identified when the installation reached bends in the road. Using the 6° deflection within Blutop™ joint, pipe layers were able to carry out the installation without needing to use bends, saving time as well as the cost of extra fittings. Time savings were also achieved where an obstruction crossed the trench, as Blutop™ pipes can be cut and jointed more quickly than plastic pipes, allowing the obstacle to be quickly circumvented.

Wessex Water commented: “Easy handling was a great benefit of using Blutop™. The reduced weight allowed operators to safely lift and lay the pipes into the trench manually, which allowed the excavator to carry out other operations. Fitting gaskets can often be difficult with small diameter pipes, but with Blutop™ this was a very quick and simple procedure.”

Blutop™ has been designed as an efficient alternative to plastics for distribution networks – particularly in contaminated ground, in complex urban situations and where high pressure or shallow or deep installation is required. Blutop™ is suited to a whole range of applications and enhances the choice that a specifier can make.

Describing the benefits of the new system, Paul Hancock of Saint-Gobain PAM UK says: “A number of key features and characteristics have been built into the new Blutop™ system to make it the optimum choice for end users in small diameter pipe systems. It has been designed to optimise and simplify installation in a variety of applications, thus reducing costs and minimising installation time. Blutop™ provides a ‘fit and forget’, leak-free solution in smaller diameters.”
