Lightweight, strong and fire resistant
Alvenius FlowMax® pipes offer a wide range of benefits compared to other systems. Alvenius steel pipes are significantly lighter thanks to the thinner pipe wall but offer the same pressure rating as a much bigger pipe. The piping system is also fireproof.


Low flow resistance means lower operating costs
High-tensile steel and spiral welding enables decreased wall thickness and 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!
The high quality of steel and Alvenius’ unique spiral welding process enables the pipes to be manufactured with much thinner walls and lower weight than traditional pipes – whilst maintaining a stable profile.
The outcome? Standard outer diameters with a larger inner diameter resulting in significant cost savings in transport, handling and installation.


Fast and easy assembly
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 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 (C5). Independent tests show that pipes coated with CorroFlo®offer a service life of more than 50 years.
Rubber lined internal surface
For transportation of slurry and extremely abrasive media.
