    Main applications

    • Cold water plumbing
    • Hot water plumbing
    • Well water and industrial transfer
    • Slippery, bright internal surface for high transmission capacity
    • Resistant to corrosion and aggressive environments

  • Wasser PP-R Composite pipe with white outer layer and maroon composite inner layerPP-R

    PP-R Composite Pipe

    A three-layer PP-R pipe rated to 25 bar, built for hot and cold water transfer, under-floor and central heating.

    Main applications

    • Hot and cold water transfer in buildings
    • Under-floor and central heating systems
    • Drinking water
    • Industry and agriculture
    • Suitable for drinking water and high-temperature service
    • Higher bore size and operating pressure than normal PN20 PP-R
    • Smooth, non-porous bore means low pressure drop and reduced noise

  • Wasser PP-R UV Composite pipe showing black UV-stabilised outer layer, maroon composite layer and green inner layerPP-R

    PP-R UV Composite Pipe

    A four-layer 25 bar composite pipe with a UV-stabilised black outer layer, for pressure lines that run in the open.

    Main applications

    • UV-exposed and outdoor pressure lines
    • Hot and cold water at high pressure
    • Well water and industrial transfer
    • UV-resistant outer layer protects the pipe from flaking in sunlight
    • Composite layer gives rigidity with memory, so runs lay straighter
    • Manufactured as per KS ISO minimum requirements

    PN12.5/25 · 25 bar · OD 20–110 mm · 4 m lengths

  • Wasser PP-R UV Protected pipes with black UV-stabilised outer layer and green PP-R inner layerPP-R

    PP-R UV Protected Pipe

    A two-layer PP-R pipe with a UV-stabilised black skin over a green PP-R core, built for drinking water lines exposed to sunlight.

    Main applications

    • Drinking water supply
    • Outdoor and UV-exposed installations
    • Hot and cold water plumbing
    • Most ideal for carrying drinking water — not subject to contamination
    • UV protected layer resists flaking in sunlight over time
    • Excellent resistance to acids, oxidizing agents, alkalis, oils and domestic effluents

    PN10/20 · 20 bar · OD 20–110 mm · 4 m lengths

  • Wasser PP-R Thermal Insulated pipe in white, showing the insulating middle layer at the cut endPP-R

    PP-R Thermal Insulated Pipe

    A three-layer PP-R pipe with a thermal insulating middle layer, for hot and cold water runs where heat loss matters.

    Main applications

    • Hot water distribution
    • Cold water distribution
    • Well water and industrial transfer
    • Better thermal resistivity than standard PP-R pipes
    • Resistant to corrosion and aggressive environments
    • Slippery inner surface — no organic or inorganic sediment build-up

    PN10/20 · 20 bar · OD 20–63 mm · 4 m lengths · White

  • Wasser HDPE pipes in black with blue identification stripes for water supplyHDPE

    HDPE Pipe

    Black high-density polyethylene pipe for water and gas, joined by heat fusion into leak-free, fully restrained joints.

    Main applications

    • Water supply mains and reticulation
    • Gas
    • Farms and irrigation
    • Municipal and infrastructure projects
    • Heat-fusion joints are as strong as, or stronger than, the pipe itself
    • Produced in 50 m to 100 m lengths, cutting the number of joints
    • Light, flexible and lower in construction cost than other pipe materials

    PN6–PN20 · 20–110 mm · 6 m to 100 m lengths · Black

  • Stacked grey Wasser PVC-U pressure pipes for water supplyPVC-U

    PVC-U Pressure Pipe

    Grey unplasticised PVC pressure pipe in 6 metre lengths for pressurised cold water supply and distribution.

    Main applications

    • Drinking water supply
    • Pressurised cold water distribution
    • Irrigation and infrastructure mains
    • Most ideal for carrying drinking water — not subjected to contamination
    • Immune to chemical, electrolytic and galvanic action, so free from corrosion
    • Self-extinguishing, which eliminates the need for fire resistant coatings

    PN6–PN20 · 40–160 mm · 6 m lengths · Grey

  • Wasser PVC-U Acoustic pipes in white showing the hollow grid middle layer in the cut sectionPVC-U

    PVC-U Acoustic Pipe

    Main applications

    • Quiet drainage stacks in buildings
    • Apartments, hotels and hospitals
    • Soil and waste where noise matters
    • Reduction in noise levels of more than 6 dB
    • Internal vanes reduce vortex and direct the flow
    • Hollow grid layout adds structural strength and rigidity

Technical information

Specifications, dimensions and product codes

Pipe composition, colour, length, outside and inside diameter, wall thickness, pressure rating and temperature guidance for every Wasser system — exactly as published in the catalogue.

Figures are reproduced from the Wasser Pipes catalogue published by Astral Industries Limited. As temperature rises, maximum working pressure falls — check the temperature tables above for the class you intend to use. Confirm final sizing, pressure class and availability with a qualified plumber or engineer and with Astral Industries Limited before ordering.
