IntroductionWind turbines depend on reliable, precision-made flanges at every joint between tower sections. Onshore or offshore, every site is unique. That’s why Eurotech Benelux wind turbine flanges are made at an ultra-modern factory from the finest material grades, to an unparalleled degree of precision, and rigorously inspected using the most sophisticated testing equipment available.

Many countries are striving to produce more of their energy through renewable means, and wind energy production is at the forefront of the movement.

To meet the increased demand, larger and more efficient turbines have been called for, which in turn asks far more of the supporting structures.

The wind turbine manufacturing industry has constantly improved the materials and technology that go into its multi-part towers, many of which are over 100m tall.

d Computer controlled forge

The factory is the one of the largest forging plants of its kind, specializing in high-end annular forgings and heteromorphic sectional forgings. Its output encompasses over a hundred grades of carbon, alloy and stainless steels and high temperature alloys of annular forgings. A dedicated centre conducts research and development into new methods and materials. When production lines were doubled in 2010, the factory’s annual production of rolled rings (500mm to 10,000mm diameter) reached 200,000 tonnes.

Other equipment includes twelve regenerative computer-controlled forging heating furnaces, and CNC rolling machines for 3500mm, 5000mm and 9000mm diameter rings, oil presses rated to 6000, 4000 and 1600 tonnes, a 1600 tonne water press, 40 tonne forges, and various heat treatment furnaces: a 9m bogie-hearth type, two 5m room type, and several well- and split-type.

Rings can be produced in any size up to 10,000mm diameter, 800mm thickness and 1500mm depth, weighing up to 35 tonnes.

The factory scrutinises its products with the latest tools: direct-reading spectrometers, carbon sulphur analysers, high-resolution optical microscopes, sustained high-temperature creep testing equipment, impact testing machines, and sophisticated electronic test apparatus.
