Industrial pipe fittings for industrial use

Maximum reliability, excellent safety, resistant to corrosion and aggressive media. Long life and superb overall cost effectiveness.

Alvenius’ complete steel pipe systems are unbeatable in demanding industrial environments.
Because these steel pipe systems are developed to meet the tough demands of the marine environment,
they are ideal in for example harbour installations, process industries, paper mills, refineries
and the chemical industry.
Stainless steel is no longer needed!

Lightweight and strong

The corrosion-protected systems provide complete solutions including pipes, couplings and pipe fittings.
Compare with other types of piping and you will quickly see a range of advantages with Alvenius FlowMax® pipes.

For example: lightweight handling, quick coupling, maintenance free and a surface coating that protects against corrosion and minimises the build-up of deposits.

Low flow resistance means lower operating costs

High strength steel and spiral welding enables
decreased wall thickness and further many benefits

  • Lower flow resistance due to the larger inner diameter and inner CORROFLO™ coating
  • The possibility of using pumps that draw less power – due to the lower flow resistance. 
  • The potential 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!

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 than with welding and is done entirely without special training or hot work.

Surface coatings that protect
against corrosion and wear

Piping 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´ll 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.
