Swagelok

The ShimTec reactor from Chart Industries [18, 19] is an example of a HEX reactor with diffusion-bonded plates (Figure 12.2). The reactor is composed of three plates one process plate sandwiched between two utility plates. All the units are made of 316 stainless steel, unless stated otherwise. Swagelok fittings are used for all the connections.

Use 1/16 compression nuts and ferrules from vendors such as Parker, Swagelok, or Rheodyne. These have similar ferrule shapes, which are compatible with each other. Note that Waters and Valeo fittings have different ferrule shape and seating depths and might not be interchangeable with others. 

Probe The probe is constrncted of stainless steel and has Swagelok fittings top and bottom for attachment to the process sample line. The constrnction of the probe inclndes a Dewar that reduces the sample heat transfer throngh the walls of the probe to the magnet components. At the sampling zone the inner wall of the probe is constrncted of alnmina ceramic which is specialty welded to the stainless. The probe is pressure tested to 1.035 x 10" Pa (103.4 bar, 1500 psi). The duplexor and preamplifier are built into the base of the probe. 

Preparation of the Columns. Columns were manufactured from 3l6 SS steel tubes l/U" x U mm diam. Swagelok 1/8" x 1/U" 3l6 SS... 

A stainless steel (ss) tube 3/8" o.d. with 1/16,f wall thickness and 10 cm long (3.2 ml) is fitted with ss screens and Millipore prefilters at the top and bottom of the stainless steel (ss) tube which is connected by 3/8" to 1/8" Swagelok reducers to 1/8" o.d. ss tubing. All of the column components are autoclaved and assembled. The top connector and screen are removed and the column is filled with 100-200 mesh Bio-Rad basic alumina in a water slurry at pH 8-9. The alumina column is clamped between two rectangular lead plates that have been machined to fit around the ss column and placed inside of a solid lead cylinder 5 inches in...

Peracetic Acm-AcErALDEHYDE Reaction. The cobalt- and manganese-catalyzed reactions of peracetic acid with acetaldehyde were studied by a continuous flow technique (9). Peracetic acid (0.15M in acetic acid) and acetaldehyde-catalyst solutions were metered through rotameters to a mixing T (standard 0.25-inch stainless steel Swagelok T) and...

Long metal columns up to 20 feet are packed in straight sections and then carefully coiled with a minimum of flexing of the tubing. For still longer columns it is advisable to pack shorter lengths and to connect these with a Swagelok union which has been bored out to permit a butt to butt seal of the column ends.
