Quick-coupling, secure and
cost-effective galvanized (HDG) pipes

Tough environment, demanding conditions, maximum operational reliability and ease of installation.

Alvenius’ complete galvanized (HDG) pipe systems are unrivalled in demanding conditions both above ground and underground, and the corrosion protected systems provide complete solutions - including pipes, couplings and pipe fittings. Over the years we have also developed extensive experience of flanged systems, rubber lined pipes and special solutions for the mining industry. 

Lightweight, strong and fire resistant

Compared with other systems,
Alvenius FlowMax® pipes offer a range of advantages.
For the same pressure rating, Alvenius
steel pipes are significantly lighter
due to much thinner pipe walls and,
above all, they are fireproof.

Low flow resistance means lower operating costs

High-tensile steel and spiral welding
enables decreased wall thickness and further many benefits: 

  • Lower flow resistance due to a larger inner diameter. 
  • The possibility to use pumps of a lower power rating
    – due to the lower flow resistance. 
  • The possibility to reduce the number of pumps in the system.  

It’s the inner diameter that counts!

Due to the high quality of the steel and Alvenius’ unique manufacturing process using spiral welding,
the pipes are made with much thinner walls and lower weight 
- while still maintaining a stable profile.

This means you can obtain pipes with a larger inner diameter for the same outer diameter. Cost savings in transport, handling and installation are the outcome!

Surface coatings that protect against corrosion and wear

Pipe systems in tunnels work in an exposed
and aggressive environment.
Alvenius FlowMax pipes are therefore supplied with different types of surface treatment to withstand for example wear, corrosion and chemicals.

We provide you with the right surface treatment
for the right application.

  • HDG - Hot-dip galvanization Ideal for pipes that are to be dismantled/reassembled, due to a very robust surface coating.
  • CorroFlo® (thermoplastic coating) Ideal for corrosive conditions where for example acidic water or aggressive chemicals are a problem.
    The surface finish also minimises the risk for accumulation of deposits on the inside of the pipe.

Fast and easy assembly. Short downtimes.

Installation is straight-forward. No welding. No special tools. No time-consuming training.
All you need are pipes, couplings and a spanner.
Assembly goes at least ten times faster compared to welding and is done entirely without special training or hot work.
