The inner and outer layers of composite multilayer EXCEL PEX ALPex are PEX; and its middle layer is aluminum combined with bonder. EXCEL PEX ALPex has most of the advantages of plastic pipe and metallic pipe. Its advantages are easy bending, anti-rust, non-corrosion, and acid resistance. It is widely used in the transportation of hot and cold water, beverages, gases, heating liquid or shipbuilding pipe.
Non-corrosion:
EXCEL PEX ALPex's inner and outer layers consist of silane method cross-linked polyethylene ( PEX ) At normal temperature, it does not dissolve in any known solutions and is resistant against acid, alkali and salt of various kinds.
Both materials offer perhaps the best chemical and corrosion resistance of any plastic used in the manufacture of plumbing pipes. The polyolefin family of plastics PEX is renowned for it's toughness, long working life and resistance to deterioration in the most extreme environments.
On the other hand, when metal or copper pipes are exposed to aggressive soil and water conditions, they are susceptible to corrosion and pitting.
Clean & Healthy:
The entire EXCEL PEX ALPex plumbing system is designed to provide you with the cleanest drinking water possible.
EXCEL PEX ALPex's clean, non-corroding plastic interior is resistant to deterioration in aggressive water conditions. You needn't worry about odor, color or taste problems arising because of the plumbing pipes in your home.
And given EXCEL PEX ALPex built in permeation barrier, you have built in peace of mind that your buried water pipes will not be permeated by ground source contaminants.
Ease of Installation:
No more copper sticks, no more sweating joints every few feet. EXCEL PEX ALPex's convenient, lightweight coils allow you to install a professional plumbing system quickly and efficiently. Installation crews are less fatigued and larger coils mean less wastage.
Need to make a bend ? Go ahead. Need to snake pipe around an obstruction ? There's nothing stopping you. When the system calls for a fitting, you simply cut, bevel, insert and crimp the pipe for secure, long-term connections. It's really that fast and simple.
MALLEABLE: Unlike garden variety PEX pipes that spring back upon bending, EXCEL PEX ALPex pipe is easy to bent and its metallic inner core gives it the “memory” to stay bent

in walls and ceilings or surface mounted. It can be supported horizontally or vertically on 8 foot centers because its stiffness and expansion rate is similar to copper's. EXCEL PEX ALPex can be encased in concrete or buried underground without additional protection because its tough outer plastic layer resists chemicals and corrosive activity.
And EXCEL PEX 's aluminum core provides a 100% permeation barrier against oxygen diffusion in closed loop system, WHICH IS THE CAUSE OF CORROSION IN PUMPS IN RADIANT SYSTEMS
Superior Flow:
EXCEL PEX ALPex's smooth inner plastic wall permanently resists scaling and mineral build-up, keeping water flow constant year after year. Unlike metal pipes, you won't see a reduction in flow area with EXCEL PEX ALPex. That means home owners can enjoy a constant water pressure throughout the house, throughout the years.
EXCEL PEX ALPex uses fewer fittings almost half the fittings used in a copper system. Fewer fitting joints means less chance of leakage and less liability.
It is not only designed for better long term flow rates, the inner plastic layer is non-corroding and won't pit, pinhole, or erode in aggressive water conditions. EXCEL PEX ALPex is designed to provide years of trouble free performance in the toughest of conditions. Other pipes just don't compare.
Low Expansion and Contraction:
EXCEL PEX ALPex's aluminum core controls the amount of expansion and contraction in the pipe. In fact although it looks like a plastic pipe its expansion rate is very similar to copper’s so you do not have to worry about building in costly and time consuming pipe offsets.
