PRESSURE PIPES | PROCESSING IMAGE: MOLECOR
Fluid situation: developments in pressure pipe
End users must be confident that pressure pipe – whether in water supply, fire safety systems or the offshore industry – is appropriate for their application
Pressure pipe takes many forms – from single-walled polyolefin pipe for water to multi-layer variants such as the thermoplastic composite pipes used in the offshore sector. In each case, the pipe must be tested and approved for use – whatever the application. Agru of Austria says it has expanded its range of
FM-approved piping systems for underground fire protection systems. The pipes are made from crack-resistant PE 100-RC, which Agru says can save costs during installation, and increase system safety and service life. The company adds that the PE 100-RC FM-ap-
proved components achieve the highest pressure ratings of 218psi/15 bar (SDR 11) and 250psi/17.5bar (SDR 9). They can be used in any project where FM approved piping is needed for underground fire suppression systems. The company makes pipes and fittings from OD 63mm to OD 630mm. The approval test carried out as part of the product expansion also made it possible to increase the pressure ratings for Agru’s pipe systems in SDR 11 and SDR 9. This could mean cost advantages for installation compared to many pipes with FM approval, it said. Its subsidiary, Agru America, has FM-certified pipe

systems in Iron Pipe Size (IPS) dimensions commonly used in the USA, meaning that Agru can supply the full range in both metric and IPS dimensions. The water supply of a fire protection system is
often considered its most critical component, as it must move water from its source to the entrance of a building. Piping must be reliable enough to withstand internal and external stresses over long periods of time. PE 100-RC pipes and fittings can be welded together by heated tool butt welding or electrosocket welding. Welded joints are as strong as the pipe itself, providing a leak-tight system. In addition, PE 100-RC pipes do not corrode. Agru offers two FM-approved product ranges
for firefighting systems: one for maximum operat- ing pressures of 218psi (15bar, SDR11 ); and one for 250psi (17.5bar, SDR9). System components are tested to handle 3.2 times the specified pressure – in case of water hammer – without failure.
