V/S |
PPCH Piping |
| No heavy duty tools or equipment required on site just pipe cutter and driling machine. simply cut pipe square & push into fittings |
Tools |
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. |
Speed |
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. |
Wastage |
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. |
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. |
Final Cost |
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. |
Failure |
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. |
Skill |
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. |
Maintenance |
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 |
