Düker Cast Iron Pipes are Stable and Resistant
•cast iron pipes are resistant to positive and negative interior pressure, even in larger
diameters
•the pressure resistance is not interdependent with medium or environment
temperature, neither at high nor at low temperatures
•cast iron pipes are absolutely UV-resistant, no material embrittlement
•cast iron pipes do not show the typical plastic phenomenon of thermal shrinkage (shortening
of plastic pipes after exposure to heat, therefore withdrawing from the socket)
•cast iron pipes are „vandalism-safe“

Düker Cast Iron Pipes are Environmentally Friendly

•cast iron pipes are manufactured from practically 100% recycling material

Düker NH pipes and fittings are manufactured entirely in the Düker works in As the first step, cast iron (scrap material) is Düker NH pipes are manufactured on a centrifugal casting plant -developed by

superior quality of the grey cast iron material. The machining and part of the coating plants are linked directly to the casting
plant.
Pipes that are intended for other coatings are withdrawn after leaving the
machining plant and coated separately.

Melting shop: Withdrawal of liquid iron from the collector

Centrifugal casting plant: pouring into the rotating pipe molds

Fittings Manufacture

Düker fittings are manufactured in the sand casting procedure.

For each single casting, the pattern is used to shape a sand
mould (for the outside contour of the fitting) and a sand core
(for the inside contour of the fitting). The pouring is done in the
moulding plant. The fittings then undergo shot blasting and
grinding, and finally coating.
