The RISE system can be used for eccentrically pipe penetrations. The pipe can be ducted off centre and even angled through the conduit opening.The system offers that most simple way of installation. The very limited amount of components makes this system easy to handle on site. The RISE system for pipe penetrations uses rubber filler sleeves and rubber sheets that expand to 5 respectively 10 times its original volume when exposed to fire. On both sides of the penetration a layer of FIWA sealant is applied.

The RISE system can be used both for vertical (deck) and horizontal (bulkhead) conduit openings. An interesting feature of the RISE system is the ability to follow any deformation of the deck or bulkhead that occurs during exposure to fire. Even under these severe circumstances RISE stays tight.

But there is more. With RISE no pre-engineering is needed, no special conduit frames have to be used, there are no restrictions on pipe types and sizes and the system is capable of withstanding mechanical loads.

RISE: the safe and simple rapid sealing system

The RISE system can be used for single metallic and plastic pipe penetrations. The RISE penetrations have been especially developed for those cases where the ducted pipe is off-centre in the conduit sleeve, so that sealing plugs cannot be used.

The RISE system is very easy to install. Use is made of rubber filler sleeves and rubber sheets that expand to 5 respectively 10 times its original volume when exposed to fire. On both sides of the penetration a layer of FIWA sealant is applied.

The RISE system is a self-correcting sealing system that follows displacements of the pipe and deformation of the deck/bulkhead in case of a fire. The limited number of components make the system easy to handle on site.

RISE: the safe and simple rapid sealing system

The RISE system can be used for multi metallic and plastic pipe penetrations. Only a minimum of distance between the sleeve and the ducted pipes is required to guarantee fire safety.

Assembly of RISE multi-pipe penetrations is a simple job. A limited number of components are used fer the sealing of the conduit. Rubber strips cut from rubber sheets are applied for wrapping fire-safe material around the ducted pipes. Only two types of filler sleeves are used to fill the empty space in the conduit opening. The sealing is finished by applying a layer of FIWA putty at each side of the conduit.

For pipe sizes up to 44 mm insert sleeves are available in a length of 80 mm with the required wall thickness of 10 mm as an alternative for wrapping the strips around these pipes.

With RISE no pre-engineering is needed, no special conduit frames have to be used, a minimum number of components is needed, there are no restrictions on pipe types and sizes and the system is capable of withstanding mechanical loads.

RISE: the safe and simple rapid sealing system

RISE single and multi-pipe transits consist of only three components
FRR/LEHF rubber insert sleeves
FRR/EHF rubber sheets
FIWA sealant

The rubber compound of the insert sleeves and sheets have been developed for the RISE system. The rubbers are known as FRR/LEHF (Fire Resistant Rubber / Low grade of expansion, Halogen Free) and FRR/EHF rubber sheets/sleeves. Exposed to fire or temperatures in excess of 200 °C, these rubbers will expand to five respectively ten times their original volume. During the expansion a carbonised mass is formed, which has good thermal insulation properties. The FRR/LEHF and FRR/EHF rubbers are absolutely halogen free and have a low smoke and a very high oxygen index.

FIWA is a fire-resistant and water repellent sealant based on a single component silicone compound. In the event of fire or at temperatures above 200 °C the sealant expands to about 10 times its original volume. The porous mass that is formed has excellent thermal insulation properties. FIWA is absolutely halogen free and has a low smoke index, a high oxygen index and low flame spread characteristics.

ABSOLUTELY HALOGEN FREE MATERIALS

The RISE system can be used for plastic pipes which pass through fire-rated bulkheads and decks. These pipes are a potential source of serious in case of fire. PVC/PE/PP pipes start to soften at a temperature of about 75 °C and ignite at a temperature of about 140 °C.

For this purpose a combination of FRR/EHF and FRR/LEHF is used in the same way as for the RISE pipe penetrations for metallic pipes. When exposed to temperatures above 200 °C or flames, this rubber mass will expand vigourously with such a force that the plastic pipe will be crushed.

For plastic pipes larger than 75 mm up to 125 mm the CSD crusher plug, above 125 mm RISE crusher collars are to be used.

RISE: the safe and simple rapid sealing system

The pipes (steel, copper,GRP, PVC, ABS, HDPE, PP) can be passed through the conduit pipe in any position. Make sure that the minimum space between the pipes and the wall of the conduit pipe is available to apply the required layers of FRR/EHF rubber.

Cut strips of the FRR/EHF rubber sheets with a width of 80 mm and a length suitable to allow the strip to be wrapped completely around the ducted pipe. Place the rubber strip around the pipe and fasten it with iron wire. If the ends of the rubber strip do not meet perfectly, seal the seam with FIWA putty. For pipe sizes up to 44 mm insert sleeves are available in a length of 80 mm with the required wall thickness of 10 mm as an alternative to wrapping the strips around these pipes.

Then apply the next strip of FRR/EHF rubber in exactly the same way. Continue doing so until the appropriate number of layers have been applied as required by the size of the ducted pipe.

Push the layers of FRR/EHF rubber into the conduit pipe in such a way as to leave about 20 mm of free space at the front. At the other side of the conduit wrap the same amount of rubber layers around the pipe and the push them into the conduit pipe leaving 20 mm of free space at the front.

The empty space in the conduit pipe should be filled up completely with insert sleeves. After the sleeves have been put in place, a 20 mm thick layer of FIWA sealant is applied at both side of the conduit. The conduit should be overfilled because some sealant will be pushed between and into the empty sleeves during finishing.

To smooth the surface, a cloth that is sprayed with soapy water is used to press down the layer of FIWA. When smoothing is finished a last check should be taken if sufficient sealant is applied.
