Polyethylene of Raised Temperature (PERT) Pipe Compound

PERT Polymeric Pipes
Scientific Introduction to PERT Pipes
PERT (Polyethylene of Raised Temperature Resistance) pipes are an advanced generation of polyethylene designed to withstand high temperatures (up to 95°C) along with high pressure. These pipes are manufactured using polyethylene with Controlled Molecular Architecture and enhanced with thermal stabilizers and antioxidants, giving them significantly higher thermal and mechanical resistance compared to conventional PE or even PE-X, while maintaining easier processability.

PERT, particularly in its Type II and Type I classes, is recognized globally as the first choice for underfloor heating systems, domestic hot water, and industrial thermal applications.

Scientific and Technical Features

• High Temperature Resistance: Can continuously withstand temperatures up to 95°C, and even higher for short periods.
• High Pressure Resistance: Operates under 10–20 bar in standard conditions.
• Long-Term Durability: A service life of over 50 years under high temperature and pressure conditions, according to ISO 9080 tests.
• High Flexibility: Easy installation in confined and complex spaces without the need for multiple fittings.
• Weldable and Connectable: Suitable for thermal welding, electrofusion, or press fittings.
• Chemical Resistance: Resistant to hard water, detergents, common chemical solutions, and scale formation.

Industrial Applications of PERT Pipes
PERT pipes are widely used in industries where high temperature and pressure are standard operating conditions:

• Underfloor Heating Systems
• Domestic and Industrial Hot Water Plumbing
• Wall and Ceiling Radiant Heating Systems
• Heat Fluid Transfer Lines in Food and Pharmaceutical Industries
• Central Heating and Cooling Systems (HVAC)
• Replacement for Metal Pipes in Renovation Projects

Economic and Commercial Advantages

• Reduced Installation and Maintenance Costs: Thanks to flexibility, corrosion resistance, and fast installation.
• Greater Resistance to Scale, Corrosion, and Stress Cracking: Unlike metal pipes or some older polymer types.
• Environmentally Friendly: Recyclable, with optimal thermal conductivity and low energy consumption during transport.
• Suitable for Residential, Commercial, and Industrial Projects: From apartments to hospitals and factories.
• Available in Various Sizes and Pressure Classes (PN): Compliant with international standards such as ISO 22391, ASTM F2769, and DIN 16833.

Comparison of PERT with Other Pipes

Why Are PERT Pipes the Right Choice for Your Project?
If you’re looking for a modern, intelligent solution for the safe transfer of hot fluids under high pressure, PERT pipes are the ideal choice. With long lifespan, fast installation, reliable performance, and cost-effectiveness, they have revolutionized the design and implementation of thermal piping systems.
