Efficiently installed, flexible, permanently leak-proof - FRIAFIT® sewage system for the largest hangar in Europe
The largest aircraft hangar in Europe is to be built in the south of the Frankfurt airport and completed by 2015. Up to four aircrafts of the type Airbus A380 will once be housed on a floor space of 49,000 square metres. The first half of the hangar is expected to be completed in 2008. A hangar of this size requires a sewage system which can be installed efficiently and which is permanently leakproof – despite high peak loads.

Use of nanomaterials for concrete pipe protection
Microbial induced corrosion (MIC) in concrete sewer conveyance systems is one of the most common types of deterioration encountered in such structures. This corrosion involves a chemical reaction between hydration products in the hardened concrete and biologically produced sulfuric acid, which alter the concrete chemical composition leading to early deterioration, loss of strength and, in extreme cases, pipe collapse due to inability to resist external earth and live loads.

New DIN standards for water pressure pipes recognise PP-RCT
During 2006, the German standards for polypropylene (PP) pressure pipes have been revised. The designations PP-H100, PP-B80 and PP-R80 have been withdrawn as they did not reflect the required behaviour at elevated temperatures and were changed to PP-H, PP-B and PP-R. Also, pioneering PP-RCT has now been officially recognised as a category under the new German standards DIN 8077 and DIN 8078 for PP pressure pipes. The creation of a new PP-RCT class means that these solutions can now be tested according to a widely accepted quality standard.
