Double pre-insulated pipe ECOFLEX Aqua Twin 40x5.5-32x4.4/175, 10 bar, temp. 70°C, for DHW installations, thermal insulation made of PE-X foam, corrugated HDPE outer jacket. /200m/ 1044015

Pre-insulated pipes for efficient hot water transport

The Uponor Ecoflex Aqua Twin double pre-insulated pipe is a solution dedicated to building efficient and durable domestic hot water installations, especially in underground systems. The design with two pipes in one jacket – one for supply water and the other for circulation – minimizes heat loss and ensures user comfort. It is an ideal choice for both professionals and investors who value energy efficiency and reliability.

Construction and properties

The pipe consists of several key elements that provide its unique properties. The inner pipe is made of cross-linked polyethylene (PE-Xa), characterized by high resistance to temperature and pressure. The closed-cell PE-X foam insulation minimizes heat loss, and the corrugated outer jacket made of polyethylene (HDPE) protects against mechanical damage and weather conditions. This makes the pipe flexible, easy to install and corrosion resistant.

The Ecoflex Aqua Twin 40x5.5-32x4.4/175 pipe is distinguished by the following features:

• Double construction: Two pipes in one jacket – one with a diameter of 40 mm (wall thickness 5.5 mm) for transporting domestic hot water and the other with a diameter of 32 mm (wall thickness 4.4 mm) for circulation, which increases the energy efficiency of the system.
• High resistance: Withstands working pressure up to 10 bar and short-term temperatures up to 80°C (maximum continuous temperature is 70°C), which guarantees safe use for a long time.
• Effective insulation: PE-X foam with a thermal conductivity coefficient of 0.04 W/(m.K) minimizes heat loss, reducing the operating costs of the heating system.
• Flexibility and ease of installation: The pipe is easy to bend (minimum bending radius is 900 mm), which facilitates installation even in difficult conditions.
• Durability: Resistant to SLW 60 loads, which means it can be used in places exposed to heavy vehicle traffic.

Application and compliance with standards

Uponor Ecoflex Aqua Twin pipes are primarily intended for transporting domestic hot water in underground networks, meeting the PN-EN ISO 15875 standard. They are perfect for heating systems, central heating installations and domestic hot water systems with circulation. A wide range of applications and high quality workmanship make them products valued by installers and investors worldwide.
