Multilayer Pipe for Water Supply and Heating Systems

 

Multilayer pipe is used for water supply and heating systems. Multilayer pipe offers unmatched durability, performance and safety for delivering water and heat safely. Also called PEX-AL-PEX pipe, multilayer pipe consists of multiple layers that optimize the best properties of each material:

• Inner PEX: Flexible PEX (crosslinked polyethylene) forms the inner flow channel. PEX provides corrosion resistance and high flow rates.
• Aluminum core: A rigid aluminum core adds strength to withstand pressure. Aluminum also resists corrosion.
• Outer PEX: The outer PEX layer protects the aluminum from damage during handling. It also resists UV light exposure.
• Epoxy adhesive: Epoxy glues the layers together into an inseparable, leak-proof pipe.

Advanced multilayer pipe solves the risks and problems inherent in outdated metal and plastic pipe systems. By fusing together the best properties of polymers and aluminum, it achieves reliable performance unmatched by any single-layer pipe. As leaders in the plumbing and mechanical systems industry, it is our responsibility to build with only the safest, most technologically advanced materials. Multilayer pipe offers that elite level of performance our customers deserve.

Multilayer pipe offers unique performance features that make it the preferred choice over antiquated single-wall metal and plastic pipes:

Flexible Design

The flexible PEX layers allow bending and routing through cramped spaces. Pipe can snake through joists, studs and suspended ceilings. Tight factory-made bends eliminate extra elbow fittings.

Fewer Joints

PEX flexibility enables long continuous pipe runs up to 300 feet. This minimizes the number of fittings compared to straight copper or iron pipes. Each eliminated joint boosts reliability.

Corrosion Resistance

Both inner and outer PEX layers resist corrosion and chemical attack from water, glycol, deionized water, saltwater, soaps and cleaning agents.

High Burst Strength

Multilayer pipe withstands over 300 PSI (20 bar) pressure - well above typical residential and commercial service pressures. The rigid aluminum core prevents ballooning.

High Temperature Rating

Continuous 230°F (110°C) hot water capability makes the pipe ideal for water heating and distribution systems.

Low Linear Expansion

The composite layers minimize expansion and contraction as water temperature changes. This prevents excessive movement and joint leakage.

Easy Installation

Joints push together and seal with rubber gaskets for fast, secure connections. No gluing, soldering, or special tools needed.

Quiet Operation

Multilayer construction dampens flow noise and prevents vibrations or water hammer.

Long Service Life

Expected 50+ year service life without corrosion or degradation exceeds all other pipe types.

With its versatile performance, multilayer pipe excels in the following applications:

Drinking Water Plumbing

Multilayer pipe provides clean, refreshing water for sinks, showers, appliances, etc. Key benefits:

• Certified safe for potable water delivery
• Won't impart tastes, odors or toxins
• Withstands municipal water pressures over 300 PSI

Heating Systems

For in-floor radiant heating, multilayer pipe provides reliable heat delivery:

• Hot water rating of 230°F (110°C)
• Flexible for bending through concrete slabs
• Won't corrode from glycol mixtures

District Energy Systems

Multilayer pipe is ideal to deliver steam, hot water and chilled fluids from central plants to campus buildings.

Industrial Fluid Transport

Corrosion resistance allows multilayer pipe to safely convey deionized water, chemicals, acids, solvents and more.
