KAP-HDPE PIPE FOR FIRE

The HDPE Pipe System for Water Supply to Hydrant, Hose Reel and Sprinkler Installations

Protection of both lives and property from fire damage is a crucial part of the design on every project. The KAP’s-Fire pipe system has unique properties that make it the material of choice for below-ground fire main pipelines. Kekendo Africa Poly experience in supplying HDPE piping means we can quickly respond to your requirements for red-striped pipe lengths for hydrants, hose reels, and sprinklers. We stock the most common lengths and diameters and can custom make any specific sizes you may need. KAP’s -Fire PE pipe is black with red stripes, for easy identification, and typically comes in 6 or 12 meter lengths, or coils for 32 mm pipe and 63 mm pipe. Key features and benefits:

• Red stripe for clear identification.
• Heat-fused jointing systems create a monolithic structure that is stronger than the pipe itself, and completely leak-free. This eliminates rubber seals which can fail over time, also solving root intrusion problems, and provides pipeline integrity when installed in unstable ground.
• No anchor or thrust blocks are needed to prevent joint blow-out when using heat fusion welded jointing. Correctly made heat fusion joints may be expected to last the life of the system and withstand thrust/end loads equal to the strength of the pipe/ fitting without adding external restraint or thrust blocking.
• Extreme flexibility of pipe allows cold bending to accommodate minor changes in direction.
• High flow capacity due to smooth bore and end-to-end jointing, and standard 12 metre lengths halve the number of joints required.
• Manufactured to “Polyethylene – PE – pipes for pressure applications” and ” Fittings for polyethylene (PE) pipes for pressure applications”
• May be installed under concrete slabs (refer to Section 5.5.4 “Under concrete slabs”) Max operating pressure of 1600 kPa at 20°C, based on minimum 50 year design life and including a safety factor of 1.25.
• System can sustain short term pressure testing up to 2000 kPa at 20°C. Testing can begin 1 hour after the last weld has cooled, and also can be undertaken with an open trench provided the temperature of the pipeline is not higher than 20°C.
• Range of flange connection kits, valves, hydrant sets and hose reels available.
• KAP’s -Fire is available in 32 mm, 63 mm, 125 mm, 180 mm and 250 mm diameters as standard stock items.
• Coils are available in 32 mm and 63 mm. larger sizes made to order.
• KAP’s -Fire HDPE pipe can be joined with Electrofusion fittings or butt wilding equipment
