BlazeMaster pipe by Ashirvad is produced to ASTM F 442 / IS 16088 in SDR 13.5; fittings to ASTM F 439. For wet systems only, not for exposed outdoor use, not for dry systems; sprinkler heads rated up to 107 C (225 F) for pendent/horizontal sidewall, 68 C or less for quick-response upright heads.

Key features

• SDR 13.5 - same pressure capability for all diameters
• Hazen-Williams C factor 150
• Non-conductor
• limiting oxygen index 60%
• Fusion by one-step solvent cement
• no cleaner/primer needed with BM-5
• Suitable for ambient 2 C to 65 C
• Approved for air plenums (UL 1887 / NFPA 90A)

Applications

• Wet-pipe fire sprinkler systems (NFPA 13, 13R, 13D)
• System risers (protected or, for 13R/13D, exposed with limits)
• Underground water pressure service per ASTM D 2774 / F 645
