MAXSPAN RH

MaxSpan RH

Description/Features

The MaxSpan R.H. thermal hanger shield is specifically designed to provide a superior safety margin for pipe mounted on pipe rollers, flat surfaces or with supports where point loading may be a concern.  These rugged units allow hanger spans up to the maximum allowed in Table 3 of the MSS SP-69. They are appropriate for either hot or cold pipe systems.  The insulation and factory applied jacketing meeting ASTM E 96A (maximum 0.02 perm) extend beyond the galvanized steel shield for a neatly sealed joint with the adjoining insulation.  Units for pipe 4” and larger include a wear/weight distribution plate of carbon steel (primer painted).  Additionally, a segment of ultra high density, 900 PSI calcium silicate is fabricated into units for 10” pipe size and larger.  The MaxSpan R.H. meets or exceeds the MSS standard for Type 40 Shields per MSS SP‑58, Paragraph 9.2.2. MaxSpan R.H. meets the ASTM E84 Standard Flame Spread -5-, Smoke Developed -5-.
