GRP Piping Failures

GRP Piping Failures
GRP Piping Failures
Glass-fibre Reinforced Plastic pipe (GRP) systems, also known as FRP pipe systems, have been succ essful in the world’s markets for more than 50 years. During this time, they have developed into a modern pipe material that is predominantly convincing thanks to its lightweight, corrosion resistance, a smooth inner surface, and easy installation...

Over-Voltage Protection on Pipelines

Over-Voltage Protection on Pipelines
Over-Voltage Protection on Pipelines
Pipelines are commonly exposed to over-voltage conditions created by AC faults, lightning and induced AC voltage from high voltage power transmission lines. To protect personnel and the pipeline from the hazardous effects of these conditions, it is critical to properly ground the pipeline and provide continuity across isolation joints for AC and...

Pipeline vibrations – Measurements under difficult conditions

In many technical applications pipelines are used for the transport of potentially flammable or hazardous gases and liquids. Vibration problems at pipelines often depend on the volume flow. Vortex shedding is a typical result of flow induced pulsations and may cause severe piping vibrations and failures. Another excitation source for critical...
