Soft Fe and Cu are suitable gasket materials for high-pressure joints, but Cu cannot be used where temperature variations are encountered. The use of soft Fe in grooves is indicated. Joints in which rubber packing is pressed outward by the fluid pressure against the gasket are satisfactory, but not at higher temperature. The use of 2 valves in series enables the second valve to be closed under favorable circumstances. Flow control valves are often fitted with a coil of small high-resistance tubing to dissipate the energy of expansion. The use of valves utilizing the principle of the labyrinth packing gland is suggested. Compressors should be designed for the particular gas with which they have to deal. In the design of converters provision should be made for (1) an outer curtain of incoming gas to act as an insulating medium, (2) a countercurrent heat exchanger with preferably small tubes of considerable length, (3) generally concurrent heat transfer from the catalyst bed to render the bed thermally stable and to prevent too great a range of temperature in the bed.
