Piping for LNG service is connected via threaded joints, flanged connections, swaged fittings, or welded connections. Welding provides the most secure connection and should be used whenever possible. Flanged connections are suitable and should be used where welded connections cannot. Threaded connections... 

If the leak path is tortuous, these techniques do not work well and a leak detector may be more suitable. For example, leaks in swage-type fittings (Section 10.3.C) and valves of various types may be difficult to detect using these methods.

Many pharmaceutical products require special applicator nozzles which are permanently attached to the tube. Alternatively, separate applicators may be supplied for fitting onto the end of the tube (by screwing or pushing) immediately prior to use. With many products, contact with a metal applicator is undesirable. Elongated plastic nozzles have therefore been developed which are either swaged into the tube shoulder in place of the normal metal end or subsequently fitted as a separate component.

To achieve the 750°F. operating temperature for the EBR-II model, Calrods are immersed in the sodium. The sodium-to-air seal for the Calrod installation is a Swage lock fitting around the Calrod. 

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. 

The FID collector assembly was modified to connect, via Swage-lok fittings, to a small bore (0.027-inch i.d.), heated, programmable, stainless steel transfer tube, manufacured by Chemical Data Systems, Inc., Oxford, Pa. 19363. The GC injection ports, FID detector, and transfer tube were maintained at lOO C for all experiments conducted. The total column effluent from the GC was conducted through the transfer tube to the detector, a Perkin-Elmer model 360 atomic absorption spectrophotometer fitted with a deuterium background corrector and a HGA-2100 graphite furnace atomizer employing a temperature dial control power supply. 

The top and bottom of most batteries are capped with shiny, tin-plated steel (or brass) terminals to aid conductivity, prevent exposure of any zinc and in many designs enhance the appearance of the cell. Some of the bottom covers are swaged onto the zinc can, others are locked into paper jackets or captured under the jacket crimp. Top covers are almost always fitted onto the carbon electrode with interference. All of the designs try to minimize the electrical contact resistance.
