Ply-pipe multi-layer pipe

Solar Conect, agents for Powertech Solar Ltd, advocates the use of Ply-Pipe in Underfloor Heating Systems

because it:

• is both flexible and rigid
• is supplied in coils of 100 and 200 metres
• colour-coded for different applications/properties
• can be buried in concrete, underground, in plaster etc without a sleeve or tube cover
• saves about 50% on insulation
• can be detected by simple metal detectors
• is non-corrosive and compatible with most chemicals
• is smooth on the inside and does not build up scale
• absorbs pressure shocks (hammering) in the system and does not create noise
• its aluminium layer provides a complete oxygen barrier, thereby eliminating the disadvantages of oxygen diffusion
• is lightweight – copper pipes are 3 to 4 ties heavier for the same applications and galvanized steel is 10 to 12 times heavier
• is simple to install

Also

• the flow rate (over its lifetime) is 30% greater compared to similar sized copper or steel pipes despite having the same bore, due to lack of scale build up
• its flexibility reduces the number of fittings required per installation and can be installed around girder columns, pillars and bulkheads in one continuous length
• its connectors are easy to assemble and to use
