PEX-AL-PEX Multilayer Pipe

PEX-AL-PEX pipe is a five-layer composite pipe that combines the advantages of a metal and plastic pipe and eliminates the disadvantages of both materials at the same time. The aluminum core is absolutely diffusion tight; it reliably prevents oxygen/gases from permeating into pipe. It compensates and reduces snap-back forces and heat expansion with changes of temperature.
 PEX multilayer composite pipe consists of an overlapped or butt welded aluminum core with an inner and outer layer or high temperature-resistant polyethylene. All layers are permanently bonded together by intermediate adhesive layers. The aluminum thickness for PEX-AL-PEX pipe has been selected to meet compressive and flexural strength requirements.

Overlapped welded PEX pipe is co-extruded with one step with perfect adhesive between inner layer and aluminum, high and stable pressure resistance, of which welding style is ultrasonic.

The aluminum core is continuously overlapped or butt-welded and prevents oxygen/gases from permeating into the PEX pipe. Consequently, the corrosion of metallic installation components is avoided.

PEX-AL-PEX Corrosion resistant

The smooth inner and outer plastic layers hold water at bay- preventing deposit accumulation and corrosion. At normal temperature, it can withstand all kinds of acid, alkali, and salt solution.

PEX-Standard PEX-c

PEX is cross-linked polyethylene. Through one of several processes, links between polyethylene molecules are formed to create bridges (thus the term "cross-linked). This resulting material is more durable under temperature extremes, chemical attack, and better resists creep deformation, making PEX an excellent material for hot water and other applications.

PEX 's flexibility and strength at temperatures ranging from below freezing up to 200 degrees Fahrenheit makes it an ideal piping material for hot and cold water plumbing systems, service lines,  hydronic radiant heating systems, snow melting applications, ice rinks and refrigeration warehouses.

The flexibility of PEX allows it to be supplied in coils meaning installations under the slab can be made in a single, continuous length without the need for fittings. PEX is not affected by concrete.

PEX saves money in many ways. For the installer, PEX tubing is competitively priced. Installation of flexible systems is fast because of the easy handling of the tubing and PEX installation requires fewer directional fittings. Since most plumbing problems occur at joints, fewer fittings also reduce the chances for leaks and callbacks, saving the installer even more time. The homeowner saves in the cost of the installed system, and can reduce utility costs in some layouts .

Home run or manifold plumbing systems utilizing PEX tubing can substantially reduce water and energy consumption in a home. The home-run concept provides dedicated direct lines from the manifold to the fixtures, reducing the amount of water that must be purged from the lines to get hot water at the fixture. Direct lines can be sized to the fixture requirements, further reducing the amount of time to wait for hot water. Faster hot water delivery reduces water waste and the amount of times the water heater must cycle to supply hot water.
