ABSTRACT:
A piping system for conveying one or more product flow lines within an outer casing includes a layer of insulation on each of the product flow lines to prevent heat lost and an improved spacer arrangement forming an interface between the product flow lines and the casing to prevent damage to the casing and flow lines as well as reduce friction when the flow lines are pulled through the casing. The spacer includes a pair of halves that can be assembled together using a bolted connection, for example, with flanges provided on the halves. An integral polymeric body comprises each of the halves with projecting portions spaced circumferentially about each of the spacers, the projecting portions extending longitudinally and radially and having inclined surfaces that lessen stress during the pulling of product flow lines through the outer casing. Annular shoulders on the spacer mate with corresponding annular shoulders of the insulation layer to prevent heat loss at the interface.
