Tubes made from high-quality, dense-sintered Al 2O 3 ceramic are reliable components in the plants of the glass and metal producing and processing industries, industrial kiln engineering and the basic chemical industry. In such plants, the service conditions often require an extremely high strength of the ceramics shape in a corrosive environment and a high thermal shock resistance. Commercially available tubes from six manufacturers were tested in an orientational study, with regard to these properties. The results of the tests revealed some drastic differences between the various types. Among the dense-sintered ceramics, the materials and products behaviour of Degussit AL23 demonstrated the optimum combination of these three properties. The Degussit AL23 strength of shape is only surpassed by Degussit AL24, a material especially developed for the high-temperature technology. Source

The Rheinhütte Pumps Division of FRIATEC AG has developed FNC Series of pumps made of Frikorund® and Frikotherm B® for the ceramic industry. Frikorund® is a silicate ceramic that also contains corundum and other minerals. The pump components made of Frikorund® ceramic are slip-cast. Frikotherm B® is also a silicate ceramic that has been optimized to withstand thermal shock. The pump components are fabricated by means of cold isostatic pressing and machined prior to firing. After sintering, the two materials Frikorund® and Frikotherm B® are ground to final dimensions. The Frikorund® ceramic used in the FNC pump is primarily interesting for applications involving hydrochloric acid, mixed acid, sulphuric acid or nitric acid because these acids cannot attack the ceramics.

Similar problems occur when connecting pipes for repairs and integrations in water pipeline networks. The continuously growing pressure to rehabilitate leads to an increasing number of technically sophisticated material transfers. The characteristics of the different pipe materials must be considered for the prevention of consequential damages after the rehabilitation. The advantages of pipe connections with ultimate tensile strength will be explained. Source

The greatest obstacle faced by the development and expansion of fiber optics connections for homes, particularly fiber to the home (FTTH), is today the high investment needs, whereby these are essentially comprised of excavation costs. The "final mile" and especially the connection to the home are major cost drivers. The solution at hand, developed by SWB Regional GmbH, uses the existing water mains connection to connect an empty conduit to the building, through which the fiber optics cable can then be fed to the home. This poses not only technical questions, but also raises hygiene concerns. All of the pilot studies to date have proven the functionality of the solution and confirmed the absence of any hygienic risks. Further future testing shall now determine the solution's suitability for use. Source

A New Generation of Electro fusion: A technical comparison between the new wedge coupler and the traditional cylindrical coupler for PE pipes d1000 (40″) and above. We have developed a totally new concept of electrofusion jointing method for large bore PE pipes, d1000 mm (40″) and above. The new method completely revolts existing practice with respect to easy installation, fast progress and minimal energy consumption. Compared with standard EF fittings in large dimensions the new technique allows a dramatically reduction in processing time, eases installation and does not require additional devices on site. Basic design criterion of the fittings is maximum reliability in processing of the joint under rough site conditions as well as durable operation of the pipe system. The presentation introduces the new concept, shows the advantages of the new method and highlights processing with respect to practical and economical aspects. Source
