The largest plastic energy chain in the world

The largest plastic energy chain in the world
Energy chain expert Igus has developed the largest ever plastic energy chain in the world for offshore applications on offshore oil drilling platforms. The new E4.350 is wear-resistant, maintenance-free and resistant to seawater and mineral oil. Its material is naturally corrosion-free and the high-performance plastics from which it is made of are lighter and less expensive than comparable stainless steel energy chains. 

When the drilling rig is moved on to an oil platform ("rig skidding") the plastic energy chains will be able to move 15 metres up and down during the drilling head stroke ("top driving"). This guarantees the heavy hydraulic cables are guided and protected. Igus presented the E4.350 energy chain at the Hanover Fair for many such tough tasks in conditions dominated by ice, wind, storm, salt water, oil and drilling mud. The energy chain has an internal height of 350 mm and a variable inner width of 200 mm to 1 metre, giving a large internal capacity. Large cables and hoses with a diameter of up to 300 mm are guided stably by the plastic chain, with a potential fill weight of more than 100 kg/m. 

The special design of the E4.350 ensures extremely high torsional stiffness and stability. Thanks to an interlocking tongue and groove bolted joint, the links move easily. Additionally, special inner/outer link design ensures a straight run and quick assembly, especially when compared with the steel alternatives. Integrated sliding surfaces, larger wear surfaces and particularly strong stop-dogs ensure a very long service life. Even gliding use is possible for very long travel distances. Centre links increase stability even more and make it possible to extend the width of the energy chain almost without limit. Other special designs are possible. Finally, there is a comprehensive, easy to assemble, modular range of accessories including internal cable separation and shelving parts.
