Multilayer  Pipe Market

Multilayer pipe sales in Australia are about to receive a major boost in the Multi Storey Residential and Commercial markets. Snap Fire Systems has released a Fire Collar that closes the plastic/aluminum pipe up to the largest available size of 63mm. A 4 hour Fire Resistance Level (FRL) is now possible with a SNAP Gas Fire Collar, Composite pipe and a 4 hour concrete floor.
“The Residential & Commercial high-rise and Aged care facility market had been previously off limits to composite pipe, due to the pipe needing to pass through Fire Rated Walls or Floors. But architects, builders and contractors can now utilise the benefits of composite pipe in many more installations with the introduction of this Fire Collar.” SNAP Fire Systems managing director Brett Magnay said.

Measurement of foam core pipes has so far been a special challenge. Control of the functional layers has due to the specific material properties not been possible with conventional measuring equipment. Now a digital ultrasonic system is available which provides accurate „inside information” also on foam pipes.

Raw material is foamed during processing which produces small air bubbles. They enlarge the material volume and as such the wall thickness size. This saves raw material and reduces costs in a particularly important segment. However, air bubbles cause measuring problems due to the fact that they reflect ultrasonic signals. Consequently, it has so far not been possible to measure interior layers. Foam pipes are normally co-extruded pipes and it is recommendable to control the geometry of all layers in order to minimize material consumption. INOEX has now found a solution for this technical challenge: a new AUREX digital ultrasonic measuring technique….. more: KWD-globalpipe, 2008-11-25, No. 300

Aleris Aluminum in Belgium is one of the leading suppliers of aluminium strip to the multilayer tube manufacturers in Europe. We offer the following technical advantages to our customers:

Special Multilayer tubing alloys
