2016 Berlin : Asset management of polyethylene gas networks
Author(s) : Ian Aldridge, Declan Robinson, Dave Smart, Chris Reed, Martyn, Greig, Trevor Stafford, David Christie-Lowe, Alec Erskine
For the UK polyethylene (PE) gas pipe network, the first installations now exceed 40 years in the ground, with an original design life of 50 years. It was thus timely to review the current condition and performance history of these first generation PE materials. A major 4 year project was started in 2010 to examine...
2016 Berlin : Assured quality of butt fusion and electrofusion welding of PE100 pipe
Author(s) : David Chrystie-Lowe
The many benefits of PE100 pipe materials include flexibility and toughness in addition to being relatively light products that are not subject to corrosion and expected to last well beyond the design lifetime . It is also a distinct advantage that end-load resistant joints can be made using butt fusion (BF) and...
2006 Washington DC : Solutions to Installation Difficulties with PE Pipelines
Author(s) : MacKellar, Lowe, Ingham, Ashdown
Polyethylene (PE) is the preferred material for 90% of all water mains laid in the UK.
The pace of renovation of dilapidated cast iron water networks has led to the increasing
demand for coils of flexible PE pipe, driven by the efficiency of using less joints and
taking up considerably less space in the congested...
1998 Gothenburg : Aliphatic Polyketones in Pipe Applications
Author(s) : Gray, Powell, Bonner
Aliphatic polyketones are a family of polymers prepared by the polymerisation of olefins and carbon monoxide in a perfectly alternating sequence. BP Chemicals produces these materials using a proprietary palladium catalyst in a continuous polymerisation process.
They are crystalline thermoplastics which offer a unique...
1988 Bath : The Abrasion Resistance of Polymers Used in Slurry Transport Systems
Author(s) : Lowe, Marshall
A Rotating Pipe Drum Test has been developed to assess the abrasion performance of plastics pipes to an extpnt where most test variables are understood. The procedure involves the rotation of relatively short pipe lcngths containing slurry on a conventional bail mlll. In the rest, the pipe surface repeatedly passes...
1985 York : The Abrasion Resistance of Polymers in Slurry Environments
Author(s) : Lowe, Marshall
A new test has been developed to evaluate the abrasion performance of different
pipe materials. The Rotating Pipe Test simulates sliding bed flow of a slurry and
gives quite excellent data reproducibility. The influence of sample geometry and
slurry changing frequency and particle size have been assessed. The effects...
