SML pipes – the classic amongst cast iron, collarless sewage systems from RSP® comprises a range of more than 240 pipes and fittings. SML has been used in a wide variety of areas for decades. Whether in airport buildings, exhibition halls, office/hotel complexes or residential buildings, the SML system with its outstanding properties reliably performs its services everywhere.
SML pipe and SML fitting from RSP® are characterised by high-quality surfaces with the best drainage properties. The system also impresses with its coating quality, which goes far beyond the standard (e.g. RAL quality). One of the most important properties of SML pipes and SML fittings, their positive behaviour in the event of fire, has been tested and certified by MFPA Leipzig GmbH according to the latest regulations of DIN EN 877/A1, as of January 2010, for the entire RSP® system.
