pb pipes and plastic pipe which is better?
PB is the best, aluminum pipe in PE-RT to warm the interior of the tube was added aluminum layer prevents oxygen from entering the pipeline to speed up the scale condensation, but to warm the pipe is to use beans stone backfill mortar, oxygen already entrance, superfluous.
Comparison of two phases, then aluminum is a good point of plastic pipe, aluminum plastic pipe to overcome the cracking and deformation pb pipe!
PB pipe: PB pipe is a German invention, has nearly 30 years of history in Europe since 1971 and mass production, but after three to five years of practical application, it was found pure plastic tube bending portion produces cracks, deformation off plug phenomenon, and aging, resulting in leakage or water can not flow. & Nbsp; & nbsp; & nbsp; & nbsp; aluminum tubes: As pure plastic pipe cracking, deformation off plugs, inventor to think in a plastic tube outer add a layer of aluminum, the main purpose of that is to take excellent ductility aluminum , and later in order to protect the aluminum outer layer plus a layer of PE, while glue layer between PE and aluminum, aluminum and become seen on the market five-layer structure of the composite pipe. Aluminum pipe is excluded galvanized iron pipes (rust) and pure plastic pipe (oxygen permeability and will bend, jam) shortcomings, and combines the advantages of both products and services.
