26. Some Technical Specifications
Flanges Connections: Flange type B1 according DIN EN
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 ( micro inch).
CF flanges (or UHV) are for vacuum and high temperature

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 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.
