Fire protection pipework
Sprinklers. Hydrants. Water mist. Systems that wait decades for the moment they must perform flawlessly.
TAVINOX PRESS is a stainless steel press-fit system with PAVUS certification to VdS CEA 4001. Ø22–108 mm, wet and dry systems.
Why stainless steel for fire protection pipework
Fire protection piping spends most of its lifetime idle. Stagnant water causes pitting corrosion in carbon steel.
No corrosion in stagnant water
Sprinkler and hydrant systems are filled with water that does not flow. Unlike carbon steel, stainless steel does not undergo pitting corrosion under these conditions.
Stable flow rate
No corrosion products, no deposits. Flow on system activation matches the design results even after decades of operation.
Does not block sprinkler heads
Corrosion particles from carbon steel are a known cause of sprinkler failure. Stainless steel does not produce corrosion particles.
Resistance to cyclic loading
Pressure tests, filling and draining, temperature changes. Stainless steel handles these cycles without issues.
Suitable for wet and dry systems
In wet systems it resists stagnant water; in dry systems it resists condensate that naturally forms in the pipework.
Long service life
Eliminates the need for a full replacement of fire protection pipework after 25–30 years, which is standard practice with carbon steel.
