Some Technical Specifications Flanges Connections: Flange type B1 according DIN EN 1092-1 Smooth finish with spiral woung gasket THE MOST USED SURFACES ARE Stock Finish The most widely used of any flange surface finish, because practically, is suitable for all ordinary service conditions. Under compression, the soft face from a gasket will embed into this finish, which helps create a seal, and a high level of friction is generated between the mating surfaces. The finish for these flanges is generated by a 1.6 mm radius round-nosed tool at a feed rate of 0.8 mm per revolution up to 12 inch. For sizes 14 inch and larger, the finish is made with 3.2 mm round-nosed tool at a feed of 1.2 mm per revolution. Spiral Serrated This is also a continuous or phonographic spiral groove, but it differs from the stock finish in that the groove typically is generated using a 90-deg tool which creates a "V" geometry with 45° angled serration. Concentric Serrated As the name suggests, this finish is comprised of concentric grooves. A 90° tool is used and the serrations are spaced evenly across the face. Smooth Finish This finish shows no visually apparent tool markings. These finishes are typically utilized for gaskets with metal facings such as double jacketed, flat steel and corrugated metal. The smooth surfaces mate to create a seal and depend on the flatness of the opposing faces to effect a seal. This is typically achieved by having the gasket contact surface formed by a continuous (sometimes called phonographic) spiral groove generated by a 0.8 mm radius round-nosed tool at a feed rate of 0.3 mm per revolution with a depth of 0.05 mm. This will result in a roughness between Ra 3.2 and 6.3 micrometers (125 - 250 micro inch). CF flanges (or UHV) are for vacuum and high temperature 20 October, 2011 5th Thermosyphon Workshop

5th Thermosyphon Workshop Conclusion Ordering for TS circuit almost completed. All components for TS to be delivered at the end of 2011. We will start construction phase of the “balcony unit” beginning of 2012. We need a 2nd welder. We have to integrate the installation of the condenser and its accessories in the schedule. We’ll order all components for Brine circuit before end of 2011. 20 October, 2011 5th Thermosyphon Workshop
