Vista PE-AL-PE Multilayer composite Pipes combine the advantages of
metal and plastic pipes and eliminate the disadvantages of both
materials at the same time. The aluminum core in the composite pipe is
absolutely diffusion tight and reliably prevents oxygen or gases from
permeating into the pipe. It compensates and reduces snap-back forces
and heat expansion with changes in temperature. Vista PE-AL-PE multi
layer composite Pipes consist of an overlapped aluminum core with an
inner and outer layer of polyethylene - PE. All the layers are
permanently bonded together by intermediate adhesive layers. The
aluminum thickness of Vista composite pipes has been selected to meet
compressive and flexural strength requirements. Role of PE Layers: PE layers of composite pipe provide all the advantages of plastic pipes such as, corrosion resistance, scale resistant. Chemically inert. Smooth surface for better flow properties. Toxic free, rust free. Role of Adhesive Layers: The tie layers have the following functions: To perfectly bond the metal and plastic. To absorb eventual shifting movements between the plastic and the metal, likely to occur in opposite directions. To give the Composite pipe the advantages of a single component pipe. Role of Aluminum Pipe: In addition to all the inherent advantages of plastic pipes the inclusion of the metallic pipe gives Composite pipe the qualities of metal, namely: It act as a permeation barrier against entry of contaminants. Limits oxygen permeability to virtually zero Provide absolute tightness, mechanical resistance to deformation. Dilation within reasonable limits. Increases malleability so bendable. Low heat expansion Vista Pipe fittings are specially designed for hi-corrosion and hi-pressure resistant, every sector of which imparts strengthening into pipe, is able to avoid leakage of gas and liquid, and is not affected by moving, connecting easily; the tighter the nut, the tighter the fitting in the pipe. All these ensure against gas and liquid leakage. |
