Cold water piping systems
The KELEN pipe system is suitable for cold water plumbing and cold water drinking water systems.
The piping is made of PP random copolymer (PP-R type 3).
KELEN is a CodeMark certified product.
THE KELEN PIPE SYSTEM CAN BE USED IN THE FOLLOWING APPLICATION AREAS
- Cold Water Systems
- Cold Water Systems (Drinking water)
THE KELEN PIPE SYSTEM
The pipes are tested and approved both internally and by external institutes. Approved for drinking water. Smooth internal surface. Low heat conductivity. Long service life and high resistance to impact down to a temperature of -5°C. The fittings are also made of PP-R and are joined to the pipes by polyfusion socket welding. Metal adaptor fittings are made of dezincification resistant brass (MS63), Joints can also be made using the electrofusion welding socket, or by flange or by union.
- KE KELIT does not supply KELEN PP-R for heated water (Drinking water) applications ≥ 20°C in New Zealand, as the amount of chlorine in New Zealand's water supply can have a detrimental effect and, in combination with common design and installation practices like velocity, temperature and combination with copper, cause significant reductions in product life expectancy and durability. KE KELIT recommends only using KELEN PP-R for cold water (Drinking water) applications that have ≤ 0.4 ppm chlorine residual. Please contact KE KELIT for additional information on this subject.
- The water supply from the prescribed sources (check handbook) can be used, providing the water has been treated from all harmful contaminates as set out within this technical manual and are within the temperature, pressure and flow rate range of the KELEN Pipe System.
- Copper and copper ions have a destabilizing effect and their presence in the system shall be avoided.
- The conditions of elevated temperatures (>65°C) with the presence of copper ions, particularly when chlorine is present and velocity is above 1 m/s, can have a detrimental effect on the expected service life.
