PEX-AL-PEX Cross-linked Multilayer Pipe 95°C Hot Water & Radiant Heating

Description

Ruisongbuild PEX-AL-PEX: The Ultimate Solution for Radiant Heating & Hot Water

When it comes to high-temperature fluid transport, the Ruisongbuild PEX-AL-PEX pipe stands in a league of its own. By using cross-linked polyethylene (PEX) for both the inner and outer layers, this 5-layer composite pipe offers superior thermal stability and creep resistance compared to standard PE pipes. It is the gold standard for underfloor heating, radiator connections, and domestic hot water systems worldwide.

Why “Cross-linked” (PEX) Matters?

The cross-linking process creates a 3D molecular network that prevents the pipe from softening under high heat. While standard PE pipes are limited to cold water, Ruisongbuild PEX-AL-PEX can safely operate at 95°C (with peaks up to 110°C), ensuring long-term structural integrity in pressurized heating systems.

Key Technical Specifications

• Available Sizes: 16mm (1216), 20mm (1620), 25mm (2025), 32mm (2632).

Premium Features for Professional Installers

• 100% Oxygen Barrier: The aluminum layer prevents oxygen from entering the system, which is critical for preventing the oxidation and rusting of metallic components like pumps, valves, and boilers.

• Low Thermal Expansion: PEX-AL-PEX expands significantly less than pure plastic pipes, making it ideal for surface-mounted installations and concrete slab embedding.

• “Bend-and-Stay” Flexibility: Our pipe combines the best of metal and plastic—it can be easily bent by hand and maintains its shape, reducing the need for elbows and fittings.

• Hygienic & Safe: The inner PEX layer is non-toxic, lead-free, and resistant to scaling, ensuring pure water quality for domestic use.

Product Selection Matrix

Frequently Asked Questions

Q1: What is the main difference between PEX-AL-PEX and PE-AL-PE?
A: The core difference is temperature resistance. PEX-AL-PEX uses cross-linked polyethylene, allowing it to handle hot water up to 95°C. PE-AL-PE uses standard polyethylene and is generally limited to cold water or gas applications up to 65°C. For underfloor heating or radiator systems, PEX-AL-PEX is the industry standard.

Q2: Does PEX-AL-PEX require special tools for installation?
A: Yes. To ensure a leak-proof connection, PEX-AL-PEX should be installed using press fittings or compression fittings. You will also need a pipe cutter and a reaming tool to prepare the pipe ends before joining.

Q3: Why is an oxygen barrier important for heating systems?
A: Oxygen entering a closed-loop heating system can cause rapid corrosion of the metal boiler, heat exchangers, and circulator pumps. The aluminum layer in Ruisongbuild PEX-AL-PEX provides a 100% oxygen barrier, significantly extending the life of the entire heating system.

Q4: Can PEX-AL-PEX be used for drinking water?
A: Yes. Ruisongbuild PEX-AL-PEX is manufactured from high-quality, food-grade materials that are non-toxic, odorless, and lead-free. It meets international standards for potable hot and cold water distribution.

Q5: How long will PEX-AL-PEX pipes last?
A: When operated within its rated temperature and pressure specifications, PEX-AL-PEX has a design life of over 50 years. It is resistant to scaling, pitting, and environmental stress cracking.
