Cryogenic Pipe Supports for a LNG Plant in Algeria

The pictures above show cryogenic pipe supports designed by a Houston E&C firm for a LNG plant in Algeria. Piping Technology & Products, Inc. fabricated the these supports for a 14” pipe which operates below –50^oF. Three different materials are used. The upper part which bolts to the pipe is fabricated from an alloy which retains its strength at low temperatures. The middle section is a Permali block selected because of its strength and durability and because it is a poor conductor of heat. The bottom plate of galvanized carbon steel is bolted to the Permali block. Permali is a phenolic laminate 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.
