Penetration seals enclose and seal pipes through walls, floors and casings and compensate movements from thermal expansion of pipelines, seismic displacements and ground settlements. They seal against high level of ground water, flooding, rain, air, fire spreading, transfer of radioactivity and splash water from fire water jet. Additionally, they absorb noise, vibration and pipe misalignment.

ditec`s fire protection bulkhead sealing offer fire resistance for 120 min for pipe penetrations through walls and ceilings of wall tubes up to NB 900 and medium pipes up to NB 600. DIN 4102, Section 11 states the following: Pipe penetration bulkheads must be designed such that fire and smoke are not spread through walls and ceilings during the period of fire resistance. The fire resistance period is the minimum duration, in minutes, for the prevention of fire spreading.

The German constitution describes fire protection as follows:

“Buildings and structures … must be placed, erected, modified and maintained such that order and public safety are not jeopardized, especially not the lives and health of the public. Buildings and structures must be built such that the occurrence and spread of fire and smoke is prevented, and must allow for effective extinguishing and the rescue of people and animals in the event of a fire.”

A fire can only occur when there is enough oxygen and combustible material, and an ignition source. During the smoldering phase, the energy released by a fire heats all surrounding material. If this material is combustible, it will ignite upon reaching the limit temperature. 

The fire behavior of the construction materials is of significance until the ignition point is reached. Afterwards, during what is called the blazing fire phase, the fire resistance and the fire behavior of the component design will determine the duration of a fire in a given space. The spread of the fire depends on the design of the construction components surrounding the fire area, such as walls and ceilings, as well as the pipe bulkheads in the fire walls or ceilings.
 

Structural fire protection cannot prevent the occurrence of fires, but ensures that a fire remains limited to the smallest possible area through the building’s design and fire protection measures. For this reason, stringent requirements are imposed, particularly on structural components that run through the entire structure (beyond the limits of the individual fire compartments), such as ventilation ducts, pipelines and electric cabling. In principle, no openings may be made in fire walls. However, if these are structurally unavoidable, the structural regulations of the German states stipulate that fire and smoke must not be able to spread to other floors or fire compartments in the event of fire. A simple system for preventing fire and smoke spreading through pipe penetrations through walls and ceilings is through the use of “fire protection bulkheads”. 

We have a system certified by the Building Inspectorate that can be used to create bulkheads using non-flammable pipes in fire walls or fire ceilings. These elastic seals accommodate axial and lateral pipeline movements against the wall or ceiling and ensure reliable bulkhead in the event of fire. Movements occur as a result of thermal pipeline expansions during plant operation or, in the event of a fire, because of additional pipeline expansions and the relative movement of the building with regard to the lines as a result of wind loads, building displacement or earthquakes.

Measurement

Wall and ceiling seals are measured and manufactured after the pipeline is laid. This means that the location of the medium pipe with respect to the wall pipe and the position of the installation seam can be taken into account. The seals are dimensioned once the laid pipelines are in their final positions and the pipe insulation is complete at least in the area of the bulkhead. All the information relevant to their manufacture is listed on a form. Please note that each wall or ceiling face should be listed separately and that the opposing positions should be listed as Pos. 1 and Pos. 1A. We will take the measurements for you if desired.

Installation

Our optimally equipped installation team will install wall seals for new construction or retrofitting activities; 
we can also appoint a field supervisor to train your workers and to support and monitor installation activities.
