Preise SML's cast iron socketless pipe system
Cast iron is the classic material for domestic drainage pipe
Since 1982, the cast iron socketless pipe system has completely replaced the socket drainage pipe. A tried-and-tested pipe material, easy to handle fittings and reliable couplings provide for a space-saving, fail-safe and durable pipe system that fully meets the high demands of today’s quality of living standards and state of the art technical building requirements. At the same time, it fulfils many critical safety requi- rements such as sound insulation and fireproofing.
Due to the high level of quality in SML systems, these cast iron pipes are used for the most important sections of pipe systems in a building’s drainage system (downpipes, collecting pipes and box-type inside rainwater drainpipes).
On the outside, SML pipes are coated with a reddish brown 40ɥm thick base coating in accordance with DIN EN 877 that can be repainted with any standard color varnish or finish commercially available. On the inner side, the coating is sprayed with a completely cross-linked, ochre-colored epoxy material (120ɥm), thus, protecting the pipe from aggressive domestic effluents.
For quality assurance reasons, the „German Institute for Quality Assurance and Certification“ (RAL), Sankt Augustin, took the lead and founded the Gütegemeinschaft Entwässerungstechnik Guss e.V. (GEG - German Association for Drainage Technology Castings).
Its main objective is to guarantee excellent product quality also for the future - documented by the quality label (RAL-GZ 698). There are suppliers who do not comply with the required quality objectives which have always been a relevant criterion for cast iron drain pipes. The quality label takes into account the need for safety of all our partners, such as distributors, craftsmen, planning firms or authorities.
The quality label is awarded upon successful completion of an extensive initial test by independent, recognized test institutes. In addition, the test institutes conduct ad hoc external inspections at least twice a year to assure the quality of the products to meet the stringent quality requirements.
These measures guarantee consistently high quality and spell out the great responsibility of manufacturers towards their partners in the market, for example distributors, fitters and end customers.
