Safe, cost-efficient steel pipe systems

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.

Lightweight, strong and fire resistant
Low flow resistance means lower operating costs

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!

Fast and easy assembly. Short downtimes.

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.

Moreover, the weight of FlowMax® CorroFlo® pipes is about 1/3 that of cast-iron pipes, which has a positive effect 
on freight and installation costs.

Surface coating protects against corrosion
and wear

Piping systems are used in tough conditions.
Alvenius FlowMax® piping systems are supplied with a suitable surface coating for maximum service life.

  • HDG - Hot-dip galvanization

    HDG (Hot-Dip Galvanized) is an ideal surface coating for pipes that may need to be dismantled and reassembled as it provides a highly robust surface layer. Such pipes are highly resistant to impact, wear and harsh weather conditions. What’s more, the zinc layer “heals” if damaged.

  • CorroFlo®

    Alvenius FlowMax® pipes are coated both internally and externally with CorroFlo®. These pipes are ideal for environments and applications where, for example, acidic water and aggressive chemicals are a problem.
    Tests show that CorroFlo® meets the requirements for the extremely demanding corrosion class SS-EN ISO 12944, which applies to marine environments (C5-M) and underground (Im3). Independent tests show that pipes coated with CorroFlo® offer a service life of more than 50 years.

  • Rubber lined inner surface

    For transportation of slurry and extremely abrasive media.
