PEX-AL-PEX Tubing
The Advantage of Plastic and Metal Combined
PEX-AL-PEX tubing represents a groundbreaking fusion  of plastic and metal engineering, combining the corrosion-resistant properties  of PEX plastic with the structural advantages of a metal pipe. Classified as  Grade B and featuring an overlapped design, this tubing stands out for its  innovative construction. Grade B PEX is chosen for Duda Energy PEX-AL-PEX for  its remarkable strength which provides a higher burst pressure than typical  Grade A PEX. 
Crafted  with a PEX inner and outer layer, the tubing is reinforced with a strategically  placed aluminium core, forming a durable and flexible composite structure. The  aluminium not only enhances the tubing's rigidity, making it effortlessly  bendable and keeping it in the desired shape without the need for additional  elbows, but it also serves as a highly effective oxygen barrier. This prevents  corrosion of adjacent metal components, ensuring long-lasting performance. 
PEX-AL-PEX  tubing outshines regular PEX tubing in numerous aspects. The added rigidity  from the aluminium core simplifies installation, making it easy to shape and  preventing the tubing from resembling a tangled mess. The tactile feedback  during bending helps prevent over-bending, ensuring precise configurations  without the risk of kinking. 
The  tubing boasts low roughness and true inside diameters, resulting in optimal  fluid flow with minimal pressure loss. With a low coefficient of hydraulic  resistance, it excels in efficiency and performance. Ideal for radiant floor  heating applications, PEX-AL-PEX tubing exhibits an extended service life,  providing a reliable solution for both residential and commercial settings. 
Premium  Construction: This PEX-AL-PEX tubing boasts a  length of 100 or 50 meters (160/320 feet) and features a robust structure with 2 to 3mm total thickness. The PEX  layer is 2.7mm thick, ensuring durability and longevity. 
Top-Grade  Material: Crafted from the highest quality Grade B  PEX-AL-PEX, this tubing is equipped with a 0.3mm aluminium layer for enhanced  strength. The oxygen barrier is a crucial component, making it ideal for use in  radiant floors, glycol loops, and floor heating/furnaces. 
Wide  Temperature Range: With a remarkable working  temperature range from -40?C to 95?C, this tubing is suitable for various  applications. Its reliable performance ensures efficient operation even in  extreme conditions. 
High Pressure  Resistance: Designed to withstand high pressures,  the tubing has a working pressure of 2.5 MPa (362 psi) and a maximum bursting  pressure of 5.0 MPa (724 psi). This exceptional pressure tolerance ensures  reliable and safe performance in demanding applications. 
Certified  Quality and Longevity: ISO9001 certified, this PEX-AL-PEX tubing guarantees quality and adherence to industry  standards. Boasting a service life expectancy of 50 years, it is a reliable  choice for domestic water supply, glycol loops, and any application where longevity  and performance are paramount. Safe for use with potable water, it provides  peace of mind for various plumbing needs.
