Product Description
Product Detail
PEX-AL-PEX Multilayer Pipe/Tubing For Water Plumbing & Heating
PEX-AL-PEX multilayer pipe, known as MLCP pipe (multilayer composite pipe), which is a innovation of single PEX pipe.
The PEX-AL-PEX multilayer pipe has a five-layers' structure: the PEX-b (cross-linking polyethylene) in inner & outer layers ensures the pipe can be used for hot water (the max. working temperature reaches to 95℃). The aluminum core layer in middle greatly strengthen the pipe’s intensity (The PEX-AL-PEX multilayer pipe can bear much higher working pressure than single PEX pipe, whose max. working pressure can reach to PN1.0Mpa), at the same time, it can reliably prevents oxygen/gases from permeating into the pipe, which can protect the steel/brass accessories from rusting for long time use. The two layers of adhesive between PEX & aluminum layers ensure the pipes’ entirety & reliability.
The PEX-AL-PEX multilayer pipe combines all advantages of a metal and plastic pipe. The superior performance makes PEX-AL-PEX multilayer pipe be the best choice for hot water plumbing & underfloor heating systems.
※ Flexible and easy to install
The PEX-AL-PEX multilayer pipe is flexible, with min. bend radio 5 times of pipe outer dia. The pipe can be installed easily, no welding, only very simple tools required.
※ Good performance for high temperature
The PEX-AL-PEX multilayer pipe are stable for use for high temperature, with max. working temperature 95℃ for 50 years.
※ Oxygen barrier pipe
The aluminum core layer can reliably prevents oxygen/gases from permeating into the pipe, this will protect the brass parts from rusting
※ Health & suitable for drinkable water supply.
The PEX-AL-PEX multilayer pipe is hygienically and neutral in material, even in case of high PH-value fluctuation of the tap water.
※ corrosion free
PEX-b is kind of inert material, it is stable against solvents and other chemicals
