Tekst profiel RU


Over a period spanning more than two decades, Rotec has developed into a leading player and in fact is market leader in the European market for flanges ranging in diameter from 25 to 2500 mm and elbows from 25 to 600 mm in GRV (glass fibre reinforced vinylester) and GRE (glass fibre reinforced epoxy). Rotec also supplies pipe system related products such as tees, reducers and glass fibre reinforced plastic pipes in diameters up to 600 mm. We supply the majority of our products directly from our production facility and warehouse in Lelystad, The Netherlands. In some cases our production facility in India or our office in Dubai handles distribution to end-users.

Wide range of high-quality products

Rotec focusses on the production of high-quality composite flanges and fittings. These specifically have been designed for composite piping systems, composite tanks and scrubbers. Recently tailor made flanges and connections for relining of pressure pipes have been added to the product range. Rotec also supplies glass fibre reinforced plastic (GRV) pipes and GRV Backing Rings for thermoplastic piping systems.

Rotec has a broad experience with the production of composite flanges and fittings using Resin Transfer Moulding (RTM) technology. Besides standard products, Rotec offers customized flanges and fittings on request. By keeping many of our products, including pipes, in stock, fast delivery is one of the key benefits we offer to our customers.

In addition to components for pipe systems, Rotec also supplies other custom made composite products, also made by RTM and VI technology. With various computer-controlled machines, special operations are performed, including screw milling in composite products for inserting inserts.
