Flexible Pipe system for automotive LPG in service station constructions System advantages • fast and simple to install without welding and x-raying of welds on site • no downtime and only minimal interruptions to petrol sales on retrofits • the most cost effective pipe system General Description FLEXWELL®-LPG Piping is suitable for automotive LPG (Autogas) buried installations of service stations in both vapour and liquid phase. LPG's main constituents are Propane (C3H8) and Butane (C4HI0) which have different boiling points : - 45 °C for propane and - 2 °C for butane. The actual mixture of propane and butane of any automotive LPG marketed varies considerably from one country to another, depending on their sources of LPG. The mix of propane and butane has a profound impact on design requirements of LPG fuelling components; the one for a propane only mix being the most stringent. Care must be exercised in the selection of the minimal design requirements as the equipment may turn to become unsuitable, if the LPG marketed in a country is being changed to propane richer mixtures in view of changing national sources of LPG. FLEXWELL®-LPG Piping is designed for operating temperatures from -50 °C up to 60 °C and operating pressures of PN 25 (360 PSI) as indicated for propane only mixtures. Application FLEXWELL®-LPG is a single walled flexible pipe system designed for the underground transport of LPG. Typically FLEXWELL®-LPG Piping is used as an underground liquid feedline and vapour return between the LPG storage tanks and the liquid gas dispenser in fuelling stations. Construction The flexible composite pipe has a helically corrugated primary pipe. This is manufactured of EN 1.4404 stainless steel (US equivalent: AISI TP 316 L) and has excellent corrosion resistance characteristics as a result. Around this carrier pipe, high-strength reinforcing bands are fitted, which effectively limit longitudinal expansion even at high operating pressures. Corrosion protection for buried installation in the ground is afforded by an external PE-LD jacket. Installation FLEXWELL®-LPG Piping is manufactured in standard factory lengths up to 700 m. The pipework is supplied on a cable reel or coil allowing it to be run directly off the reel or coil into position in the pipe trench. The corrugated primary pipe and the helically fitted reinforcing bands give this piping system remarkably good flexibility and ease of laying. FLEXWELL®-LPG pipework can be cut to the required length on site and, as necessary, bent through very tight angles to run around, under or over existing services. PIPESYSTEMS Flexible solutions
