etec Enamel in Water Supply Networks High-performance surface protection for fittings and valves

Enamel in the Past and Today The histories of enamel and metal are closely en- the development of new enamel qualities which can be applied in one layer twined. The use of enamel can be proven since the and with reduced layer thicknesses, depending on the requirements, and at that early Bronze Age (1800 B.C.). Numerous civilised remain elastic and shock-resistant. A well-known area of application is the so- peoples of prehistory and early history have left us called “white goods”, household appliances such as washing machines and cultural and artistic objects designed with enamel. dishwashers,...

etec Enamel – the Optimum Formula The enamel frits used for etec enamel are a for- melt, a thermal-mechanical pre-treatment of the cast iron surface is inevitable. mula that was specifically made up for Düker. It is The surface is cleaned with abrasive shot blasting material. In addition, this adapted optimally to the requirements of the base process enlarges the surface and therefore allows an optimal adhesion and material ductile cast iron, the manufacturing process and particularly to the necessary resistance and food safety for the use in drinking water For the application as wet enamel,...

Complete Enamelling – a Modern and Integra Inside enamel Outside enamel Inside enamel has been the standard lining for all Düker valves since 1957. In Complete enamelling is an enormous challenge for addition, Düker also supplies fittings with inside enamel. The advantages of many manufacturers. In particular for the valves, the inside enamel are obvious: design must be adapted in a way that all surfaces can be enamelled all around and with as few machined Protection against inside corrosion: surfaces as possible. Düker has completely revised Enamel is diffusion-resistant and therefore protects...

al Surface Protection Enamel defies all weathers A particularly intelligent solution is the use of outside enamel on pillar hydrants, which defy all weathers for decades. Absolutely UV-resistant: Unlike many other materials, enamel does not chalk and maintains its colour intensity for many decades. An important information: chalking is not only an optical problem. When epoxy coatings begin to chalk, the corrosion protection is also affected! Dirt-repellent: Due to its permanently smooth surface, enamel is easy to clean and therefore practically graffiti-resistant. Resistant to climate: Enamel...

Quality Certified and Documented The observance of DIN 51178 and the dev guidelines for the enamelling of valves and fittings for water supply is not only documented through the Düker quality management system as per EN ISO 9001:2008. On top of this, Düker subjects themselves on a voluntary basis to a regular third-party monitoring by the MPA Hannover institute. A corresponding report about the latest monitoring can be obtained from the factory at any time.
