Fire-fighting systems

Because it saves lives

There are as many as 70,000 fires every year in Germany, destroying economic assets to a value of several billion euros. According to insurers, one in three fires in industrial facilities results in a loss of over 500,000 euros, as well as entailing far-reaching consequences for the business. Preventive fire protection by means of fire extinguisher and sprinkler systems can save lives and avoid economic loss. 

Viega fire protection solution – simple and universal


  • Viega system solutions do not require highly compacted special fire protection covers; the necessary insulating shell provides insulation and fire protection in one
  • No costly and complex additional bonding required
  • The cross-seams of the mineral wool covers can be arranged in any numbers and locations; the system is always assured for acceptance
  • Wide range of piping systems and combinations with other isolation systems are available
  • The extensive tested fire protection system permits virtually any combination
  • Planning and installation are simple, and assured for acceptance 


  • Available for all Viega piping systems: Profipress, Sanpress, Sanpress Inox, Prestabo, Megapress, Raxofix, Sanfix Fosta, Raxinox
  • Fitting all external pipe diameters from 12 to 108.0 mm
  • All insulation thicknesses are fire protection tested according to EnEV and DIN 1988-200; various stone wool insulating materials (pipe insulation coverings and lamella mats) may be used for floor lead-ins
  • Zero clearances can be implemented between all Viega piping systems in many combinations 

Ready for anything – including zero clearance

Fire protection systems for buildings are becoming increasingly complex, and ever more important. The latest updates from the Berlin-based German Institute of Construction Engineering (DIBt) on matters such as mixed installations and clearance rules must be observed. Viega will make your active and passive fire protection work easier, and more universally applicable – such as in relation to zero clearance. You can trust in Viega’s extensive general construction technique test certifications and testing procedures, as well as in its wide range of fire protection system solutions. 

Sprinkler systems 

Sprinkler systems are fixed, automatic fire extinguishing systems which deploy extinguishing water in a targeted manner as soon as a fire starts in order to delay the spread of a fire or prevent it from spreading in the first place. Sprinkler systems are subject to the supervision of special certification bodies. You can find approved applications and the limits of use of the press connector systems in Table 1.


The Viega Profipress, Sanpress Inox, and Prestabo hot-dip galvanised systems are approved for the fire hazard classes LH (low hazard) and OH (ordinary hazard). You can find approved applications and the limits of use of the press connector systems in Table 1.

Sprinkler systems in accordance with the VdS guideline

The Megapress system is an exception 

In buildings subject to high risk, such as industrial and commercial facilities, sprinkler systems made of thick-walled steel pipe are essential – and stipulated by law – owing to their robustness, stability and durability. After all, they must not only resist the intense heat in the event of a fire but also withstand the stringent external operational demands in everyday use.

Viega Megapress with the sizes from 3⁄4 to 4 inches is ideal for construction and extension of such sprinkler systems. The system complies with the specifications of the highest risk classes and has VdS certification. Until now it was permitted to use only grooved coupling systems or welded systems in the highest fire hazard classes (production risks [HHP] and storage risks [HHS]). With Megapress, press technology can be used without any concerns in such environments. 

Fire extinguishing systems 

Fire extinguishing systems are fire protection means which serve to protect people and buildings. Regulations state that wall hydrants should be usable to extinguish fires as soon as they start.

The Viega Profipress, Sanpress, Sanpress Inox, Megapress and Prestabo hot-dip galvanised systems are suitable for fire extinguishing systems provided the system-specific conditions are fulfilled. 


Viega press systems are approved for fire hazard classes LH (low hazard) and OH (ordinary hazard). Sanpress Inox is suitable for use in new installations and renovations of fire extinguishing systems and wall hydrants. You can find approved applications and the limits of use of the press connector systems in Table 2.

Fire extinguishing systems in accordance with DIN 14462

List of media

Viega press connection technology with the Sanpress, Sanpress Inox, Profipress, Prestabo and Megapress systems has proven its value in potable water and building services installations over many years of application. It is increasingly being used in industrial systems which have special operating conditions regarding the pressure, temperature and concentration of the transported media. Careful consideration is required when choosing the pipe and sealing material. The "Fields of application for metal installation systems" information brochure, which is available to download on the right, will make this choice easier.

Always there for you – Viega Service 

The Viega Service Center will be glad to assist any customers with tailored recommendations in order to ensure that the optimum systems, components and seal materials are used in an installation.
