Steel pipe systems for fire protection

Alvenius delivers reliable and safe steel pipe systems for extinguishing water systems and sprinklers. Alvenius FlowMax® pipes are the absolute best solution in extinguishing water environments where 100% reliability and performance is required for decades to come.

Longest life. Best functionality.

CorroFlo®-coated FlowMax® pipes are the ideal solution. You obtain 100% functionality year-in and year-out, and third-party tests show that the life cycle of undamaged CorroFlo® pipes is at least 75 years.

Longest life. Best functionality.
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.

Surface coating protects against corrosion and wear

  • 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.
