THORBURN FLEXIBLE PIPING SPECIALIST COMP-FLEX DURABLE EXPANSION COMPENSATORS PACKLESS GUIDED CONSTRUCTION SIZES 3/4" TO 4" Just what is Thorburn's Comp-Flex compensator and what does it do? Thorburn's Comp-Flex compensators are small diameter multi-convoluted bellows. They are fully shrouded and specifically designed to absorb expansion and dimensional changes in anchored small diameter straight pipe runs. Thorburn Model HPC-503 1 Internal guide ring maintains alignment of inner pipe and housing and prevents contact of the bellows and housing 2 Traveling pipe or tube isolates belows from internal flow 3 Installation clip 4 2-ply bellows for longer cycle life 5 Anti-torque device on threaded models 6 Shroud provides external protection for bellows 7 Fixed pipe or tube end Also available with flanged and welded connections Operating temperatures up to 750ºF Operating pressures up to 175 psi APPLICATIONS ■ Heating and air conditioning piping systems ■ Steam, hot water and chilled water piping systems ■ Replacement of pipe-loops-slip joints THORBURN COMP-FLEX ADVANTAGES QUALITY • SAFETY • EXPERIENCE C O M P A R E ■ Ends pipe expansion noise - Uncontrolled expansion in piping systems causes unpleasant noises. Thorburn's Comp-Flex compensators eliminate this problem. ■ ■ Minimize pressure drop - Straight line Thorburn Comp-Flex compensators minimize pressure drop by eliminating multiple bends to absorb pipe motion. Prevents pipe buckling - When the pipeline is properly aligned, guided and anchored, all pipe movement is absorbed in the Thorburn Comp-Flex compensator. Narrow-wall construction the Thorburn Comp-Flex compensator way Thick-wall construction the old-fashioned way ■ Durable and maintenance-free - Thorburn's Comp-Flex's lifetime design permits the unit to outlast most piping systems, maintenance-free. ■ Broad range sizes, end connections and material - Thorburn Comp-Flex are available in standard sizes from 3/4" to 4" for copper tube, steel and stainless steel pipe; available connections are threaded, welded or flanged. Extra piping eliminated the Thorburn Comp-Flex compensator way Pipe-loop method the oldfashioned way Page 64
