Composite Piping System

Wavin Vectus Industries Limited manufactures PE-AL-PE multi-layer Composite Piping Systems, which are composed of an aluminium core encased in an inner and outer layer of Polyethylene. All the layers in a composite pipe are permanently bonded together by intermediate adhesive layers. The level of thickness of the aluminium layer in Wavin Vectus Composite Pipes has been selected to meet compressive and flexural strength requirements. This helps to combine the advantages of metal and plastic pipes and eliminate the disadvantages of both materials at the same time. The aluminium core is diffusion-tight and reliably prevents oxygen or gases from permeating into the pipe. It compensates and reduces snap-back forces and heat expansion with temperature changes.

Wavin Vectus Black Composite Pipes are manufactured as per IS standard 15450:2004 while Yellow Composite Pipes as per ASTM F- 1282.

The available range of Composite Pipe & Fittings varies from 1014 to 4050. (These sizes are available in White/Orange/Blue colours also and will be manufactured as per the order)

The life span of these pipes is more than 50 years.

Advantages of PE layers
PE layers in Composite piping systems provide all the benefits of a plastic pipe which include:

  • Corrosion & scale resistance
  • Chemically inert
  • Smooth surface for better flow rate
  • Non-toxic & rust-free

Advantages of Adhesive layers

  • Perfectly bond the metal and plastic layers.
  • Absorb eventual shifting movements between the plastic and the metal layers; likely to occur in opposite directions.
  • Give the Composite pipe, advantages of a single component pipe.

Advantages of an Aluminium core

  • It acts as a permeation barrier against the entry of contaminants.
  • It limits oxygen permeability to an absolute zero.
  • It provides mechanical resistance to deformation.
  • Restricts expansion or contraction which could occur due to a change in temperature.

  • Thermal Conductivity: The Thermal conductivity of a Wavin Vectus Composite Pipe is 0.45 W/m-K, about 1/100 than that of a steel pipe, but only several times higher than that of insulation material.
  • Chemical Resistance: The inside and outside Polyethylene is a kind of symmetrical & non-polar material with a stable characteristic. At normal temperature, it does not dissolve in any solution and is resistant against various kinds of acids, alkali & salts.
  • Hygienic Property: Wavin Vectus composite piping systems are hygienic, toxic-free, rust-free & resist the growth of micro-organisms preventing contamination of water. As medical & oxygen supply pipes, they are absolutely safe & the purity of the media of these pipes is maintained at all times.
  • Burning Resistance: The PE- AL-PE composite structure gives the composite pipes a much better burning resistance as compared to any other Polyethylene pipes. In the test, the burning resistance of the Wavin Vectus Composite Pipes reached grade BL & GB 8624 stipulations for wire & cable conduit plastic materials.
  • Hydraulic Function: The roughness coefficient of a Wavin Vectus Composite Pipe is 0.007. The inside wall is very smooth, scale-free & low flow resistance. This makes the pipes ideal for carrying fluids. Due to the hard but flexible composite structure, the lashing pressure is quickly eliminated, thus no disturbing sound occurs.
  • Installation: Wavin Vectus Composite pipes are bendable but never spring back and do not deform under pressure.
