Potable water project in Czech Republic nears completion

involved the reconstruction of part of the existing DN 600 potable water main running along the same railway track and from the highway to the river Bilina. A total of 5.7km of Hobas CC-GRP WaterLine systems DN 500, PN 16, SN 10000 were used for the project, which was completed in 2006. Between Libesice u Zelenic and the Ledvice power plant, the line passes beneath roads, along the river Bilina, beneath a camping site, a public pool, a sports ground, gardens and green space, before finally reaching the wall of the trained river. From there, the original steel pipe on suspensions was preserved and the protective pipe around it was exchanged for Hobas pipes. The line continues through green space, roads and the train station, and ends in a shaft. The section between the station and another shaft, which also connects to the Chlum water reservoir, was reconstructed in 1999, and reconstruction works could be taken up from that point, ending at Ledvice power plant. Hobas Engineering GmbH – Austria info@hobas.com www.hobas.com full scale in accordance with ASME B40.200, and are actuated by a sensitive bimetal helix coil. Silicone-free gel in the thermometer stem dampens vibration effects. Swagelok thermowells for general industry are designed to protect the thermometers from contact with viscous, pressurised, corrosive, or abrasive process fluids. They also enable removal of thermometers for replacement or service without affecting the process or system. The thermowells feature standard 304 stainless steel constructions, and 316 stainless steel upon request. The product is available in straight, reduced, and tapered shaft designs. Instrument connections include ½" female NPSM straight and female G1/2B connections. Process connections include flange, sanitary clamp, threaded, and weld socket in ½" to 2" sizes. Thermowells for sanitary applications are 3-A compliant.

regarding the magnetic field created by a nearby railway track. Satisfied with the performance of the Hobas pipeline, the client again opted for the company’s CC-GRP pipe for the Zelenice-Bilina extension project, launched in 2004.

THE Bilina potable water project in the Czech Republic was partially implemented in 1998, and included the installation of around 1km of Hobas CC-GRP WaterLine ® DN 500, SN 10000, PN 16. One of the reasons CC-GRP was chosen over steel and cast iron was that it is non-conductive and therefore corrosion resistant,

The extension project was co-financed by the EU programme ISPA, and

Almost 6km of Hobas WaterLine DN 500, PN 16 were used for the extension of the potable water main along the river Bilina

Swagelok expands temperature measurement devices range

thermometers and thermowells for general industry is a natural complement to our existing product line.”

SWAGELOK has launched new bimetal thermometers and thermowells for general industry, to expand its temperature measurement devices line, which includes thermometers and thermowells for sanitary applications. The dampened-movement bimetal thermometers operate in measurement ranges from -70º to 540°C (-100° to 1,000°F) and are available in adjustable- angle, centre-back, and lower-back mount process connections. Each Swagelok thermometer is factory calibrated, and the products feature external reset for field calibration. “Our customers depend on Swagelok products to provide high integrity measurement and tighter process control of their systems,” commented Bill Menz, market manager for process instrumentation. “The addition of
