Beisai supplies a comprehensive range of no-hub SML pipes and fittings from DN 50 up to DN 300, in part up to DN 400. SML pipes are also called SMU pipes by some users. 

Cast iron is the classic material for domestic drainage pipes.

SML – since 1982, the cast iron socketless pipe system has completely replaced the socket drainage pipe.

SML (SMU) pipes are suitable for installation inside buildings. SML pipes and fittings can also be laid in concrete without problems, as the length expansion coefficient of cast iron and concrete are very similar, and as concrete protects cast iron from corrosion.

SML pipes can also be installed outside on a buildings (as a rain water down pipe) or for example in underground parkings. 

Outside, SML pipes can be overpainted with customary coating systems.

Inside SML pipes have an ochre-coloured, fully cross-linked epoxy coating, which surpasses the requirements of EN 877 by far.

SML fittings bear an epoxy coating of the same quality inside and outside, which, however, is also reddish-brown to adapt them to the outside colour of the pipes.

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).

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 colour varnish or fi nish commercially available. On the

inner side, the coating is sprayed with a completely cross-linked, ochre-coloured epoxy material (120ᶣm),

thus, protecting the pipe from aggressive domestic effl uents

Find custom-made SML pipe and fittings that can be used for fulfilling different kinds of specific purposes. These accessories are mainly treated as one of the leading aspects of the modernized plumbing system, you can contact us, we cangive you several advices about sml pipe. 

BEISAI SML pipe and fittings have got standard quality, and they have been specially designed by using casted iron.
