Water and wastewater system for the future
Stronger - Faster - More flexible

Coated steel pipes have long been a well-proven and accepted material for water and wastewater installations.

That´s why Alvenius FlowMax® pipes are particularly suitable for permanent systems for raw water, drinking water and wastewater. More over – transition pipes and temporary installations are other typical examples of the FlowMax® pipes´ workability.

New installations, completions or extension to an existing line – Alvenius FlowMax® pipes are developed for the future´s water and sewerage systems:

  • Long service life
  • Complete product system for all needs
  • Unbeatable simple handling and quick installation

Ideal for drinking water

Thanks to the CorroFlo® coating, Alvenius FlowMax® system is ideal for transporting drinking water.
The surface coating complies to 
all hygiene specification requirements 
plus it effectively prevents internal build-up in the pipes.

The CorroFlo® coating is approved for distribution of drinking water all over the world, the pipes are diffusion-proof and approved for usage in contaminated areas.

Ideal for drinking water
Maximum durability

Maximum durability

Alvenius FlowMax® has been developed 
to work far into the future.
Thanks to the high strength steel and the very resistant 
surface coatings we can ensure a pipe system with 
high dependability and durability.

The FlowMax®-system handles different working conditions and of course there will be no changes in the mechanical properties in the long run.
Thanks to well-proven couplings and high tolerance specifications, leaks in joints are eliminated.
Changes in length, temperature differences or vibrations 
is perfectly handled by a FlowMax® system!

CorroFlo® superior surface coating

CorroFlo® (thermoplastic coating) is a non-porous 
and all-embracing coating with high mechanical 
and impact resistance.

The CorroFlo® coating is applied to both the inside and outside and provides superb long-term protection against corrosion and other wear and tear. CorroFlo® also complies to all hygiene specification requirements plus it prevents 
internal build-up in the pipes.

CorroFlo® superior surface coating

  • Facts on CorroFlo®

    • Extremely good adhesion – no risk of cracks or flaking
    • Ideal in outdoor environments – insensitive to UV, flexible down to -70° C
    • Working temperature in air – up to +60° C
    • Corresponds to C5-M. I.e. very high resistance to corrosion
    • Electrically insulating
    • Flat surface finish: 0.05 mm
    • Layer thickness 500 μm

  • Advantages of internal coating

    • Excellent resistance to corrosion, chemicals and abrasive media.
    • Optimal hygiene properties – no build-up in the pipes, thanks to the slippery coating
    • Bisphenol A free
    • Extremely low flow resistance ensures lower energy consumption and lower total costs.
    Absolute surface roughness: 0.05.

RocShield® on the outside

RocShield® on the outside

For additional wear and impact protection, the outside of FlowMax® pipes are treated with RocShield® 
– an extra 500 µm LDPE layer on top of the CorroFlo® coating.

RocShield® is perfect for pipes in exposed environments, plus the coarser surface finish provides a surer grip which makes for simpler and safer handling.

  • Advantages of external coating

    • Unbeatable service life – proven in third party tests in extreme environments
    • Resistance to external forces on pipes
    • Excellent resistance to corrosion
    • Flexible and easy to repair in the event of possible damage

Quickest installation on the market

Thanks to their low weight the FlowMax® pipes are easy to handle and the well-proven quick couplings ensures you can install the system quickly, safely, easily 
and without any preparatory work whatsoever.

No special tools, no special training needed, no welding involved – you save considerable installation time, as there is no need for cooling and X-raying of welding.

Also on-site cutting is fairly simple.

Thin walls mean larger outer diameter.

Thanks to the high-strength spiral-welded steel the result is a pipet hat is light-weight, very strong and with thin walls. 
This means a pipe with a larger inner diameter 
for any given outer diameter.

You can also keep a defined flow rate or end pressure but choose a pipe with a smaller outer diameter. 
Whichever you choose, a FlowMax® pipe is 30-50 % lighter 
than conventional pipes.

Complete system for all needs

Alvenius FlowMax® is a complete system with pipes and 
pipe fittings from DN80 to DN500, couplings, bends, 
tapping fittings, adjustable fittings, project unique fittings 
and adapters in various dimensions and variants.

Using reducer couplings or flange reducers, you can easily connect FlowMax® pipes to other types of pipes - such as PE or ductile iron – and connecting the pipes to pumps and valves is a breeze.

Complete system for all needs
FlowMax® - superior perfomance

FlowMax® - superior perfomance

Alvenius FlowMax® pipes offer unrivalled performance compared to any other system, and the combination of a range of advantages make the pipes unbeatably cost effective.

FlowMax® pipes give you loads of operating benefits:

  • You can specify pipes in smaller dimensions, but still retain the same pump capacity
  • You can specify smaller or fewer pumps in the system
  • Your will get both lower investment costs and operating costs  

A future proof water and wastewater system

With Alvenius FlowMax® system you can easily design and dimension a water and wastewater system that allows for future expansion of for example a residential area, or for an expanded number of water consumers.
No additional pipes will be required and no pipes will need to be replaced with larger dimension pipes.

Alvenius FlowMax® systems are dimensioned 
for higher pressure than other systems
and offer significantly lower flow resistance.
