Piping Technology & Products, Inc. fabricated cryogenic pipe supports
designed for a 14-inch pipe at a LNG plant in Algeria. The pipe operates below
minus 50 degrees F, therefore the pipe supports were fabricated from three
different materials in order to accommodate the low temperatures. The upper
part, which clamps on to the pipe, was fabricated from a stainless steel plate
that retains its strength at low temperatures. The middle section is a laminated
phenolic block made from layers of wood impregnated under vacuum with a
synthetic resin. A crossed orientation of the hard wood fibers is used to
provide extra strength. The laminated phenolic block, which is a poor conductor
of heat, was bolted to the bottom plate of the galvanized carbon steel.
