Cast iron elbow SML 100/15 (gray cast iron socketless) 10041

SML Drainage System – Cast Iron Elbow 100/15

The SML cast iron elbow 100/15 is an element of a spigot and socket pipe and fitting system, designed for the construction of gravity drainage and stormwater installations inside buildings. Made of socketless gray cast iron, it provides a durable and reliable connection within the system. The SML system is manufactured in accordance with EN-877 standard, guaranteeing high quality and safety of use.

Construction and properties

The elbow connects SML pipes using clamping sleeves – clamps, straps or connectors. The external surface of the pipes and fittings is coated with a red-brown primer with a thickness of 40 μm, which can be additionally painted with varnish. The internal protective layer is a fully crosslinked epoxy resin in ochre (yellow-brown) color with a thickness of 120 μm, providing resistance to aggressive wastewater. Fittings have an epoxy resin coating on both the inner and outer surfaces, baked at a high temperature (approx. 180°C) for 45 minutes – this ensures exceptional durability and chemical and thermal resistance.

Advantages of the SML system – safety and comfort

The SML system is distinguished by a number of advantages that will be appreciated by both installers and end-users:

• Fire protection: Cast iron products are non-combustible (class A2 according to EN 13501), non-toxic and maintain their functional properties even in the event of a fire. The walls remain impermeable to flames and gases, and the integrity of wall and ceiling penetrations is maintained.
• Sound insulation: The high density of cast iron and rubber gaskets minimize the transmission of material sound, ensuring quiet wastewater drainage.
• Chemical and thermal resistance: The epoxy resin coating protects against aggressive substances contained in wastewater and high temperatures.
• Durability and stability: Cast iron is characterized by resistance to impact, deformation and temperature changes. Low thermal expansion allows for concreting of pipes without risk of damage.
• Ecology: The material is 100% recyclable, and production is based mainly on the use of iron scrap, minimizing the impact on the natural environment.
• Quick assembly: The SML system is easy and quick to assemble, does not require specialized tools.
• Anti-corrosion protection: The improved epoxy resin coating provides long-lasting protection against corrosion.
• Smooth inner surface: Ensures free flow of wastewater and minimizes the risk of blockages.
