Alvenius piping systems
Alvenius provides reliable and safe steel pipelines for fire protection in road tunnels. The pipework is designed to protect life and property in these highly demanding environments. Because Alvenius piping systems have been developed to meet the most stringent requirements of the marine environment, they are ideal for use in road tunnels where previously stainless steel was the only alternative.
Alvenius FlowMax® pipes are supplied in diameters from 89-508 mm and are available for both low and high pressure systems, with the standard range withstanding pressures up to 80 bar. For special applications, systems capable of withstanding pressures in excess of 100 bar can be supplied. Alvenius pipes are fitted with precision welded rings to maintain exact dimensions.

Unrivaled durability Alvenius FlowMax® pipes are protected inside and out with CorroFlo® coating - a thermoplastic coating that is the best solution for this type of environment, where 100% functionality for decades is required. With CorroFlo® coating, the corrosion protection is second to none, as it is resistant to acidic and alkaline substances and various chemicals. Tests show that TP pipes meet the requirements of C5-M, the most severe corrosivity class approved for use in marine environments.
Independent tests show that the service life of FlowMax® pipes with CorroFlo® coating is at least 75 years. (Testing Institute - University of Stuttgart. MPA Stuttgart, Otto-Graf-Institut).
Always ready to work. Maximum reliability. Even if the fire extinguishing system is not used for a long time and contains corrosive water, no corrosion occurs. The system is therefore 100% ready to work when needed.
Alvenius FlowMax® pipes have a smooth interior, which prevents the accumulation of water. The outlet connections between all pipes are also self-draining.
Another advantage in these environments is that CorroFlo® coated pipes do not conduct electricity.
FlowMax® - low flow resistance High-quality steel and spiral welding enable the production of thin-wall pipes. Thin walls offer many advantages because they give a maximum inside diameter relative to the outside diameter:
- Lower flow resistance due to the larger inside diameter - Possibility of using smaller pumps - or existing pumps at lower horsepower
- Lower flow resistance may also allow a reduction in the number of pumps in the system
