Maximum safety for static and dynamic loads. The high stability of cast iron pipes really proves its worth in underground installation. As a guideline, an overburden of 0.8 to 6 m can be assumed with a simultaneous load from heavy-load vehicles of up to 60 tonnes. However, standard SML pipes do not offer sufficient corrosion protection. But Dueker TML drainpipes do. They have a coating system according to paragraph 4.14.3.2 of EN 877 – perfect for soil class II, rating number -5 to -10. Quality according to EN 877. Dueker TML pipes are made of cast iron and coated with sustainable materials on both the outside and the inside. The exterior surfaces of Dueker TML pipes have a zinc coating with a surface density of at least 130 g/m² according to EN 877, on top of which a brown two-component cover coating is applied. Inside, TML pipes are coated with a high-grade, fully cross-linked epoxy coating – the same as for SML pipes. Dueker’s hot mould centrifugal casting process guarantees a smooth, bubble-free surface, which prevents deposits. Perfect for drainpipes. Corrosion protection included. It is important to use suitable couplings for underground installation. We recommend Dükorapid® stainless steel. Dükorapid® stainless steel guarantees effective corrosion protection in the long term. Perfect for Dueker TML.
