|No heavy duty tools or equipment required on site just pipe cutter and driling machine. simply cut pipe square & push into fittings
||Heavy duty equipment required on site to fusion weld every joint. Also need electrical supply
|Thermal Expansion & contraction in the aluminium piping system is very less compare to any plastic pipes.
||Temperature & Resilience
||PPR Pipe is rigid and brittle. very high chance of failure at high temperatures / pressures due to high thermal expansion & contraction.
|Instant leak free connection made when pipe pushed into fitting. No deburring, no waiting for the cement to dry. Simple 'plug & play' system.
||After pushing pipe into fitting, the joint has to be made with specialized machine on site to weld the plastics together.
|In case of mistake fittings is simply disconnected and reused with the right connection.
||Once joint is made, any mistakes require pipe to be cut and both fittings & pipe cannot be reused - wastage is often very high with PP-R jobs.
|Smooth glass like inner surface - minimal frictional loss.
||PP-R pipes generally have a rough inner surface.
|Actual cost comparisons made on completed projects have shown that Aluminium Piping can often be cheaper due to less wastage, less failure costs etc.
||PP-R appears cheaper on paper in a bill of materials comparison but often costs more due to wastage & especially costs of repairing failed joints.
|Once Aluminium System is pressure tested & has no leaks, the installation is complete & leaks free.
||PP-R systems can leak after installation if the welding has not been good. This is not always detectable on site.
|Simple three step process - cut pipe, place & push into fitting - no special skills required.
||User must learn the how to make sure the joint has been properly achieved. once jointed, no guarantee of no leakage unless pressure tested.
|Aluminium Piping is truly demountable and can be disconnected instantly for refurbishment or additions.
||Non sympathetic to any maintenance.
|Aluminium Piping||GI & MS Piping
|Light Weight and Modular. Hence Requires no heavy support and No skilled labours
||Heavy and requires heavy supports. Also skilled labours (welders, fitters) are required.
|Less Production down time as the system is modular (push to connect).
||Production down time is more for additional work as there is a lot of welding work required.
|The ID pipe is specially treated and hence does not react with water to form scaling and in turn gives laminar flow and no friction losses.
||After a period of time the ID id pipe get corroded due to water and in turn gives turbulent flow which increase friction losses.
|Leakage free for 10 years warranty.
||The Joining of pipe is by welding. If not done properly will results in small leakages which will add to compressor working and maintenance
