The Uniflex Pipe Concept

The Multi-layer composite pipe UNIFLEX consists of 5 layers. One polyethylene layer is applied to the inside and one to the outside of the welded aluminum pipe. Both PE layers are permanently bonded to the aluminum pipe by means of an adhesive layer. The UNIFLEX pipe structure is a successful combination of metal (aluminum) and plastic (polyethylene) together in one pipe. The result is malleable, hygienic and non-permeable piping system that is completely corrosion and scale resistant, both internally and externally.

With UNIFLEX PIPE, you no longer have to decide between metal and plastic, because the UNIFLEX multi-layer composite pipe generation combines all the benefits of plastic and metal pipes. This ensures state of the art products and quality, high degree of flexibility and endurance, coupled with high pressure and temperature stability. For plumbing, heating/cooling or radiant temperature control – there’s nothing like UNIFLEX PIPE for smart installation.

Functional properties and Advantages of various layers are as follows :

PLASTIC (PE) LAYERS : PE layers of composite pipe provide all the advantages of plastic pipes such as,

1) High Corrosion & Chemical Resistance, 2) Smooth surface hence higher flow properties, 3) Low weight and ease of installation

ADHESIVE / TIE LAYERS : The adhesive / tie layers have the following functions :

1) Perfectly bonds the Aluminum and Pe Layers.

2) Absorbs eventual shifting movements between the Aluminum and the Pe Plastic layer, that is likely to occur in opposite directions.

3) Binds & holds Composite Pipe to give it the advantages of a single component pipes' structure.

ALUMINIUM (METAL) LAYER : The inclusion of Central Aluminum Layer between two Plastic PE layers gives Composite pipe the qualities of metal pipes namely :

1) Absolute oxygen tightness & Permeation barrier.

2) Form Stability and mechanical resistance to deformation.

3) Low Thermal Expansion .

One pipe does it all

A unique bond

UNIFLEX multi-layer composite pipe consists of an overlapped, longitudinally welded aluminum pipe with an inner and outer layer of high temperature-resistant polyethylene according to IS : 15450 & ASTM F 1281 & 1282. All layers are permanently bonded together by intermediate adhesive layers. A special welding technique ensures high reliability. The aluminum thickness for UNIFLEX has been specially selected to meet compressive and flexural strength requirements.

The basis for professional installation: UNIFLEX multi-layer composite pipe

With our five-layer composite pipe, we have developed and advanced product that unites the advantages of a metal and plastic pipe and eliminates the disadvantages of both materials at the same time. This offers product advantages that are second to none: The aluminum core is absolutely diffusion tight; it reliably prevents the ingress of oxygen. It compensates and reduces snap-back forces and heat expansion with changes of temperature. The system is designed for easy, safe and fast pipe installation; simply bend, cut to length, bevel, join and press – that’s all!

All advantages:

Combines advantages of metal and plastic pipes
Corrosion resistant
Excellent long-run behavior
Sizes from 14-110mm
Heat-expansion close to metal pipes
High bending flexibility
