MATERIALS HANDLING
Flexible transport connections
Cengiz Citlak explores how, as a multi-functional component, hoses play an essential role in machine and plant engineering
H
ose applications are just as varied as the media they transport: highly temperature- resistant and extremely elastic cooling hoses prevent, for instance, X-ray equipment or processors from overheating. Flexible hoses
help make energy from the sun and geothermal power usable. Extremely sturdy and flexible hoses keep automatic cutting machines or welders supplied with oxygen, fluxing agent or fuel gas. Compressed air hoses as well as cleaning, water and delivery hoses are indispensable for structural, underground and mining engineering, as well as shipbuilding. And in the chemical and pharmaceutical industry, special hoses are used, which ensure that aggressive and toxic media can also be transported safely. To make the operation and production processes as smooth and efficient as possible for the user, hoses by ContiTech are constantly being developed. Tis results in innovative products such as the Dampf Trix 6000 Oil, which solves the conflict between the objectives of having oil resistance whilst also having a higher level of stability with regard to steam temperature, all within one flexible rubber product.
Te oil-resistant outer layer is a particularly
impressive feature of the Dampf Trix 6000 Oil. Some other steam hoses often fail quite quickly due to external oil contamination. Te temperature-resistant inner layer made from high quality EPDM allows the hose to transport pure, saturated steam of up to 210°C at 18 bar, and even 220°C at 23 bar for shorter periods of time. Te hose fulfils all the test requirements of the German Industrial Standards DIN EN ISO 6134 - 2B and its smart design makes it a reliable and safe piece of equipment – even under the most challenging of conditions. It is suitable for use in the chemical and petro-chemical industry, in refineries, in the building industry and in numerous other industrial applications.

TAILOR-MADE SOLUTIONS FOR INDIVIDUAL APPLICATIONS In close collaboration with industry and research establishments, tailor-made product solutions are also developed and produced for very specific application requirements. Te most recent example is a pressure equalisation hose that ContiTech developed for a new kind of underwater pump storage facility, which has been undergoing testing by the Fraunhofer Institute for Wind Energy and Energy System Technology (IWES) from Kassel, Germany, since November 2016 in Lake Constance, Europe’s
