Durable PE-RT Floor Heating Pipes from China Suppliers - Flexible and Efficient Heating | Factory Direct продажа
Our PE-RT floor heating pipes are produced with imported special PE-RT pipe materials, boasting excellent temperature resistance and outstanding impact resistance, as well as good low-temperature frost resistance. They are light in weight and highly flexible, and can be supplied in coils for convenient construction and transportation, making them specially suitable for floor radiant heating projects. The pipes have prominent corrosion resistance, heat resistance, pressure resistance and creep resistance, paired with non-toxic, odorless and good hygienic performance, so they can also be used for water supply systems. They support hot melt connection of pipes and fittings of the same material, featuring simple installation and reliable connection. With good thermal stability and long-term pressure resistance, uniform material quality and stable performance, they can ensure a 50-year service life when applied in heating and hot water systems. The low-temperature brittle fracture temperature can reach -70℃, allowing transportation and construction in low-temperature environments, and the impact resistance is much higher than other pipes to prevent system damage caused by rough construction. They have an extremely small bending radius (minimum R=5D), no rebound after bending, and the stress at the bending part can be relaxed quickly to avoid damage due to stress concentration. No preheating is required for construction in low temperature, reducing construction costs; hot melt connection also enables easy repair, with high cost performance.

Frequently Asked Questions
Q
What is PE-RT pipe and why is it used for floor heating?
PE-RT (Polyethylene of Raised Temperature resistance) is a special type of polyethylene material engineered to withstand elevated temperatures and pressures over long periods. It is widely used for floor radiant heating because of its excellent thermal stability, flexibility, and resistance to creep — allowing it to perform reliably in underfloor heating systems for decades.
Q
What is the expected service life of PE-RT floor heating pipes?
When properly installed in heating and hot water systems, PE-RT floor heating pipes are designed to deliver a service life of up to 50 years. This is achieved through uniform material quality, stable long-term pressure resistance, and consistent thermal performance throughout the pipe's lifetime.
Q
Can PE-RT pipes be installed in cold or low-temperature environments?
Yes. The low-temperature brittle fracture temperature of our PE-RT pipes can reach as low as -70℃, making them suitable for transportation and installation in extremely cold environments. No preheating is required before construction in low temperatures, which simplifies the installation process and reduces overall construction costs.
Q
How are PE-RT pipes connected during installation?
PE-RT pipes use hot melt connection, which joins pipes and fittings of the same material through a heat fusion process. This method creates a strong, reliable, and leak-resistant joint. Hot melt connection also simplifies repairs, as damaged sections can be easily replaced without specialized tools or complex procedures.
Q
Are PE-RT floor heating pipes safe for drinking water or potable water supply?
Yes. Our PE-RT pipes are non-toxic and odorless, with excellent hygienic performance that meets the requirements for potable water supply systems. In addition to floor radiant heating, they can also be used in domestic hot and cold water supply applications with confidence.
Q
What is the minimum bending radius of PE-RT pipes and why does it matter?
The minimum bending radius of our PE-RT pipes is R=5D (five times the pipe diameter). This extremely small bending radius means the pipes can be bent tightly without rebounding or cracking. Stress at the bending point is quickly relaxed, preventing damage from stress concentration during installation — this is especially important in floor heating layouts that require frequent directional changes.
