ADVANTAGES OF POLYPROPYLENE RANDOM PIPING SYSTEMS (PP-R)

POLYMELT's polypropylene (PP-R) products offer many distinct advantages over competing piping systems made of metal or plastic. Find out what PP-R pipes have to offer and discover how our pipes can boost the efficiency of your next building project.

Sustainability

• PP-R lasts the life of the building (or longer).
• PP-R does not leach chemicals.
• Does not increase pumping energy needed over time due to corrosion or scaling.
• The leak-resistance of our durable and heat-fused connections reduces mold and IAQ risks.
• PP-R does not emit toxic materials.
• PP-R is 100-percent free of heavy metals.
• Heat fusion allows for flame- and emission-free installation.
• Our systems can contribute to green building credits.
• PP-R is fully recyclable throughout its life cycle.
• Natural insulation and noise-reduction properties.
• Engineered PP-R has added heat stabilizers which protect our pipe and fittings from spikes in temperature and boiler malfunction.
• Suitable for direct-buried and trenchless applications.
• PP-R is durable and chemically inert and will not react with water or many dissolved chemicals in water.
• PP-R is resistant to corrosion, scaling and erosion.

Longevity and reliability

• PP-R lasts for decades in piping applications – often longer than the building in which our pipes are installed.
• Engineered PP-R has added heat stabilizers which protect our pipe and fittings from spikes in temperature and boiler malfunction.
• PP-R can be safely buried in soil, sand, or concrete without affecting performance.
• Our systems are suitable for direct-buried and trenchless applications.

Chemical purity

• PP-R is durable and chemically inert and will not react with water or many dissolved chemicals in water.
• PP-R is resistant to corrosion, scaling, and erosion—three major causes of long-term piping failure.
• Unlike copper and many plastics, PP-R piping and its connections will not leach harmful chemicals.

Leightweight materials

• Our pipe weighs 75–80 percent less than comparable metals.
• Installers can carry more pipes with less fatigue and fewer safety risks.

Installation

• Instead of glues, solders, or gaskets, PP-R uses heat fusion, which turns the pipe and fitting into a single continuous piece of PP-R that eliminates any leak path.
• PP-R offers multiple connections including fittings and valves for straightforward installation.
• PP-R joints do not crack or leak as they’re transported to installation sites.
• After a brief learning curve, contractors typically increase productivity, resulting in time savings.
• On-site prefabrication speeds installations.
• No flame, smoke, or fumes are produced during installation.
• POLYMELT systems may require fewer hanger supports because of rigidity.
• Unlike copper and other metals, PP-R will not be stolen from your jobsite for scrap value.

Cost savings

• One of the biggest cost-savers from using PP-R is installation speed.
• The cost of PP-R material is more stable than copper and other metals and not susceptible to tariffs.
• No flame, smoke, or fumes are produced during installation.
• POLYMELT systems may require fewer hanger supports because of rigidity.
• Unlike copper and other metals, PP-R will not be stolen from your jobsite for scrap value.

Performance

• Being chemically inert and hydrophobic, PP-R maintains performance without chemical treatment.
• We offer flexible lengths and connections.
• PP-R offers high volumetric flow.

Code compliance

• Our pipe meets requirements of most building codes.
• POLYMELT PP-R products adhere to NSF standards.
