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.

Quality is paramount

Expertise, stability, technology and reliability are the hallmarks of our services and products. Our production process and our suppliers are subject to stringent quality standards. We also guarantee the highest level of quality during the assembly of our products. Our quality assurance plan is ISO compliant, enabling us to guarantee the complete traceability of all raw materials, production processes and quality controls.

Know-how and support

Rotec will supply products rapidly without compromising quality. Our team of technical specialists and service-minded staff have years of experience and are fully aware of our products’ possibilities and our company’s abilities. Internal communication lines are short, allowing us to act quickly and help you in a timely and efficient manner. We will be more than happy to address all your needs, before, during and after installation or assembly.
