Below water, yet above standard Isola di San Pietro is a small island located just southwest of Sardinia. All of the island’s sewage and wastewater is transported to a water treatment plant in the town of Carloforte. After processing, the treated water is discharged into the sea via a 2km steel pipeline with an outer diameter of 429mm. The pipes lie at the bottom of the sea at a depth of 15 to 20m. In order to keep the pipes on the seabed, concrete anchors have been used at various locations. to withstand the harsh seawater. The fittings had to be delivered quickly, and specially trained divers had to perform the installation. GF Piping Systems Multi/ Joint 3000 Plus couplings in the size DN400 were selected, as they met the high requirements of the harsh environment. Using thrust blocks or

In July 2014, part of the pipeline came loose from the seabed. Problems with the concrete anchors, in combination with air in the pipeline, caused parts of the pipes to break. Water company Abbanoa SpA had clear requirements for the fittings necessary for the seabed repair of the damaged pipeline. The fittings had to compensate for the difference in the alignment of the pipes. An end load restraint fitting with a highly corrosion-resistant coating was needed

As before, the professional conference that accompanies the trade show in Hall 4 will be conducted by KCI. The Pump Summit, the international trade fair and convention for pumps, will be held in Hall 7.0 (ground floor) on 29 and 30 November. Messe Düsseldorf GmbH – Germany info@messe-duesseldorf.de www.valveworldexpo.com www.pumpsummit.com In September 2014, a team of divers arrived from a contractor specialised in working below sea level. Special balloons were used to lift the pipes slightly off the seabed, allowing the divers to slide the couplings into position.

other anchoring materials to secure the connection was not necessary. The nominal angularity of 8° per coupling side compensated for the misalignment of the pipes below sea level. A quick delivery was possible, because the fittings were in stock at the distribution centre of Georg Fischer SpA. All requested certificates and a clear user manual could also be provided on short notice.

Valve World Expo 2016 Valves and fittings are used in a wide variety of different industries. They ensure safety in the oil and gas industry, channel liquids and gases in the chemical industry, regulate incoming and outgoing water and ensure a free flow of liquid in the drinks industry.

A year before the event bookings had already been received for over 14,000m 2 of exhibition space, and 470 exhibitors from 36 countries had registered. The majority of European companies at Valve World Expo 2016 will be from Italy, UK, Germany, Spain, France, the Netherlands and Turkey. Many of the overseas exhibitors will be from the USA, Taiwan, India and China.

The fourth edition of Valve World Expo in Düsseldorf, Germany, will be held from 29 November to 1 December 2016, showcasing valves and valve-related products and parts, actuators and
