MAXSPAN

MaxSpan

Description / Features

MaxSpan thermal hanger shields are designed to provide a superior safety margin when supporting pipe with hanger spans up to the maximum allowed in Table 3 of the MSS SP-69 in clevis or clamp hangers.  These 360o thermal hanger shields provide a continuous section of insulation and factory applied jacketing meeting ASTM E 96A (maximum 0.02 perm) through the hanger and can be used on piping systems operating between +20o F. and +1200o F.  The insulation and jacketing extend beyond the galvanized steel shield for a neatly sealed joint with the adjoining insulation.  To achieve the protection required by long hanger spans, the MaxSpan thermal hanger shields utilize heavier gauge shields, and 900 PSI structural inserts (10” pipe and larger). The MaxSpan meets or exceeds the MSS standard for Type 40 Shields per MSS SP‑58, Paragraph 9.2.2. MaxSpan meets the ASTM E84 Standard Flame Spread -5-, Smoke Developed -5-.
