Erosion and water hammer testing of glass reinforced plastic pipework for topside seawater systems
- British Gas plc, Newcastle upon Tyne (United Kingdom)
Resistance to internal erosion, and tolerance to water hammer are two aspects of performance that need to be quantified to permit the cost effective use of glass reinforced plastics for offshore topside seawater piping. Testing has therefore been conducted at the British Gas Research and Technology sub-sea test facility, using purpose designed test rigs, to generate data on these topics. The erosion tests comprised 50mm nominal internal diameter GRP pipework loops, exposed to a range of seawater flow velocities from 3 to 23 m/s. Water hammer testing involved 150mm nominal internal diameter GRP pipe spools containing a variety of adhesively bonded joints, and subjected to multiple cycles involving surge pressures of up to 3 times the recommended design pressure. This paper presents the results obtained and discusses the practical implications of the findings.
