Stores of this size can be built, using standard size factory-made sandwich panels, cutting these to size, jointing and sealing on site. This form of construction is prone to fitting errors, with subsequent failure of the insulation, if not carried out by skilled and experienced craftsmen. The best system can be ruined if the base is uneven or by inexpert finishing of pipe entries, sealing, etc.

A process scheme (Figure 4.87) consists of standardized surface-mount components and can be arranged on the screen to a customized system. The software also delivers a summary considering necessary seals and pipe fittings which can be used for ordering directly (Figure 4.88). 

KEL-F gasket seals are used in the valves. When it is necessary to open the apparatus for the discharge of product, a Pyrex-glass pipe fitting with a Teflon gasket, 16, is used.

Independent of the type of PVD method used to deposit a film or a film system, the deposition process is carried out in a sealed chamber which is first exhausted to a pressure of the order of 10 5 mbar or even lower values. The glass chambers used formerly have been replaced, with the exception of glass recipients for special purposes, such as apparatus for electron microscopic preparation techniques, by those of metal. Cylindrical and cubic chambers made of stainless steel provided with various flanges and windows are used today. The walls of the chambers can be heated and cooled by water running through double-wall constructions or in brazed-on half-round pipes fitted on the outside. The vacuum chambers are evacuated by different pumping systems. The simplest consists of a diffusion pump with or without a liq-... 

Plumbing between the regulator and flowmeter and between the flowmeter and the delivery tube is most conveniently effected with /4-in. o.d. copper tubing. Connections can be of the swage or compression type, or the 45° flare connections commonly used for refrigeration lines may be used. Brass, stainless steel, aluminum, or Monel fittings are satisfactory. Connections to pipe fittings may be sealed with Teflon tape only—never with pipe dope or lacquer. 

AMERICAN STANDARD PIPE THREAD - A type of screw or thread, commonly used on pipe fittings to assure a tight seal. 

With the cleaning operation completed, carefully reassemble the various components and make all joints and connections leak-proof. Most common pipe dopes will affect adequate seal at pipe fittings, but Teflon tape is preferred. Do...

Molded ABS parts are used in both decorative and protective applications in communications equipment like telephones (see Fig. 6-3), and for appliances, business-machine housings, safety helmets, camper tops, pipe fittings, shoe heels, and so on. Chrome-plated ABS has replaced die-cast metals in plumbing hardware and auto grills, wheel covers, and mirror housings. Some typical products vacuum-formed from extruded ABS sheet are refrigerator liners, luggage shells, tote trays, mower shrouds, boat hulls, and recreational vehicle parts. The possible extruded shapes include weather seals, conduit, pipe for drain-waste-vent (DWV) systems, and the like. 

B The ECD reacts very sensitively to impurities in the gases, pipes, fittings and seals from substances with a high electron affinity like oxygen and chlorofluorocarbons (CFG). Oxygen, moisture and CFCs deteriorate the detection limit.
