PE-XA ALTERNATIVE PIPING MATERIAL SOLUTIONS

HYDRONIC HEATING – CONDENSATE RETURN

Today

• PE-Xa Product Innovation • PE-Xa Design Optimization• PE-Xa Superior Performance

INDUSTRY TRENDS

The Present

• DE systems date back to the 19th Century

• Predominately ferrous metal material

• Life expectancy 25 – 50 years

• 1 Year Warranty

• 45% to 60% of DE project costs are in piping

The Future

• PEXa systems since 1968• Pexgol PEXa VLD since 1984• Life expectancy > 60 years• 25 Year Warranty• Reduce project costs by 45% to 60%

JOINTLESS UNDERGROUND INSTALLATIONTECHNOLOGY

The Future

• Zero effects from oxygen infiltration

• Zero internal, external corrosion

• Zero internal scaling & pitting

• No Design limitations

• Low capital cost of installation • Very low operational cost• < 1% chance of pipe failure

Thermal Memory

Thermal Memory • When PEXGOL pipe is displaced from it’s

original shape, the 3D molecular structure allows the pipe to return to it’s original shape

• If the PEXGOL pipe is kinked, it can be repaired by applying heat

Impact Resistant

Impact Resistant• Impact strength (@20c) ISO 179 No Failure• Impact strength (@-140c) ISO 179 No Failure

Scale Resistant

Scale Resistant• Very low Absolute surface roughness 0.0007mm eliminates scaling (HDPE = .0015)• Low friction loss results in calculable reduced energy consumption• Excellent choice for Hydronic Heating distribution mains

Resistance To Corrosion
