About this detail

Hydronic piping runs are supported overhead by hanger rods attached directly to the building structure rather than the roof deck, utilizing type 1 clevis hangers and optional type 48 spring isolators per specifications. Non-insulated and insulated pipes feature protective saddles or shields and vapor barriers as required. Horizontal support members utilize angle iron or Unistrut sections, while surface-mounted manufactured pipe supports include sheet metal shoes for pipes two and a half inches in diameter or larger over a one-inch minimum thickness base. Rods, spring cushions, and horizontal members are sized to satisfy load requirements with a safety factor of five without exceeding allowable load limits.
