Project Details

Densoclad 70 and 70S Tapes were chosen for the complete protection of some 23km of pipeline lengths in a major wrapping contract completed by Barrier Ltd at Wallsend, Tyne and Wear. The pipeline lengths, ranging in diameter from 50mm to 500mm, have been wrapped for a project in the Cheshire brine fields.

The large diameter pipes were wrapped on a motorised rolling rig specifically designed for fast throughput with Densoclad 70S Tape using rolls of 225mm wide x 60m long. Densoclad 70S was used here because it had a stiffer PVC backing to enable it to withstand the greater tension exerted by the motorised rolling rig.

The 50mm diameter pipes were also wrapped on a motorised rolling rig but Densoclad 70, 100mm x 60m was used here. Barrier reported that their customer delivery targets were not only matched but exceeded for each pipe size.

Densoclad 70S heavy duty tape is designed for corrosion prevention of large diameter pipes, welded joints, bends and fittings. The extremely tough PVC backing combined with polymer bitumen adhesive ensure complete protection and exceptional resistance to impact by poor backfill or aggressive ground conditions.
