The flexible pipework, which has already been proven for Carlsberg in a similar installation at its brewery Fredericia in Denmark, has been installed beneath an existing roadway within a series of prefabricated plastic ducts.
Rauiso Food 90mm and 110mm diameter pipework was pulled through the individual ducts by a team of specialist engineers from Gallagher Construction (Northern) Limited, supported by Rehau’s technical team. The installation took just five days.
The Rehau solution, in PE-Xa polymer with a diffusion barrier to prevent penetration of O2 or loss of CO2 and an insulating foam layer to resist damage, was chosen by Carlsberg as a durable and cost-effective alternative to stainless steel pipe.
It meets all of the Cleaning in Place requirements of the EHEDG regulations and had the crucial advantage that it could be installed in a conduit beneath the roadway without the road needing to be dug up.
The pipe has a permanently smooth, chemically resistant inner surface and is supplied with the Rehau Everloc connection system, which produces a permanent, guaranteed leak-free joint.
