This appraisal is for a range of Flowtite Filament Wound Glass Reinforced Plastic (GRP) jacking pipes and associated fittings with flexible non-end-load-bearing elastomeric joints for installation in non-pressure applications using various trenchless techniques including slip lining, micro tunnelling and pipe jacking. This Issue 5 is a replacement for the previous version of the appraisal which had reached its 5-year expiry date.
The jacking pipes are available in sizes from DN 300 to DN 3000 with a nominal pressure classification of PN1 and stiffness ratings from SN32,000 to SN1,000,000. The pipes can be manufactured to either OD or ID series depending on the requirements of the project.
