TECHNICAL SOLUTIONS PRESSURE SEWER Networks between communes may include long rising main sections to follow uneven profiles or take the shortest path. Topographic conditions requiring the installation of lift stations are followed by sewers operating under pressure. Since the rising sections operate under pressure, a pipe with a high safety factor is required. A high quality material, capable of withstanding water hammer and pressure drops is required to cope with the high pressures encountered and the pressure variations. The pipelines and joints therefore require excellent mechanical performance to absorb the stresses, even when faced with unexpected situations. Saint-Gobain PAM’s experience of pressurised networks, gained in water distribution, mean that INTEGRAL ® system performance can be guaranteed, even at the limits of use: high pressures, water hammer, low pressures, excess pressures. PAM pipelines can be used in rising mains up to an allowable operating pressure (PFA) of 20 bars. Due to the risk of sulphide formation in these sections, measures must be taken at the end of the rising main, on return to gravity flow, to limit the effects of acid attacks (H 2 SO 4 ). • Either by creating a suitable network or by changing the network design parameters. • Or by using an appropriate chemical treatment (iron sulphate - oxygenation - hydrogen peroxide). • Or by installing pipeline sections insensitive to acid attacks. 28 Saint-Gobain PAM - SEWERAGE - 2012
TECHNICAL SOLUTIONS ■ The INTEGRAL ® pH1 range offers the advantages of an INTEGRAL ® pipewith high mechanical strength and a passive anti-corrosion coating. The high thickness (1.5 mm for DN 80 and 2.5 mm for DN 2000) of polyurethane applied to the inside of the pipe enables the INTEGRAL ® pH1 system to transport virtually all liquids encountered in industry. The seal of the polyurethane film is checked using a Holiday detector test. Contact our technical sales teams for these special applications. A complete range of fittings suitable for these networks, permitted on all routes; in order to offer a complete system, Saint-Gobain PAM offers shut-off valves, gate valves and slide gate valves, as well as “waste water” air valves. Please consult us. Saint-Gobain PAM - SEWERAGE - 2012 29
