FLEXWELL®-LPG Pipe Systems for Petrol Stations System description General descriptipn 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 (C4H10) 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...

FLEXWELL®-LPG Pipe Systems for Petrol Stations Installation guide Safety measures Take care to ensure adequate protection from mechanical damage to the piping during laying and subsequent construction work. In particular, ensure that no mechanical damage can occur to above-ground FLEXWELL®-LPG connection joints, e.g. by providing protection against vehicles driving against them. FLEXWELL®-LPG Piping must be fitted with a system to prevent the permissible working pressure being exceeded during operation. Please take this into account when planning the installation of safety equipment. Free...
