CSD SLIPSIL – Wet Condition Duct Sealing

CSD SLIPSIL

Waterstop Duct Seal Plugs

CSD SLIPSIL Waterstop Duct Seal Plugs are designed to seal metallic or plastic pipes and cables against gas and water ingress at pressures in excess of 2.5 bar and fire resistant for up to 2 hours – duct seal plugs are available in a range of sizes to suit services between 5mm and 520mm in diameter.

SLIPSIL duct seal plugs ensure ducts or building entries are dry and that water pressure does not build up behind the seal which could cause failure during the curing of the sealant layer and consist of 2 equal parts which allow them to be inserted after all pipes or cables in a conduit are installed.

The sealing plugs are designed for best use in empty or single service building entry or cable duct ends but can also be used to seal in running water conditions. In this instance the duct must be circular and have an internal diameter within the sealing tolerance of the sealing plug of -1mm/+0.7mm.

The plugs can be used in a very wide temperature range. Even at low temperatures down to -50° C (-58° F), the rubber stays flexible and does not harden excessively as other rubber types will do. The service life of the SLIPSIL plugs easily exceeds 20 years under normal environmental conditions.

For applications with multiple cables or where re-entry for adding, removing or replacing cables is required, CSD NOFIRNO duct seals are available – view the complete range of CSD Sealing Systems.

CSD DUCT SEAL PLUGS

Installation for watertight and gastight cable duct or building entry applications:

Step 1 – Before starting the installation, any dirt or oil residues should be removed from the conduit opening. The internal diameter should be checked to make sure it is within tolerance of the CSD SLIPSIL sealing plug selected.

Step 2 – The inside wall should then be treated with CSD lubricant along a distance which approximately corresponds with the length of the sealing plug.

Step 3 – The inside surfaces of both segments of the sealing plug need to then be covered with CSD lubricant.

Step 4 – The outer surfaces of both segments of the sealing plug need to be then covered with CSD lubricant.

Step 5 – Place both segments of the sealing plug into the conduit opening as far as the first serration. This should be placed around the pipe or cable if one is ducted.

Step 6 – Push both segments of the sealing plug evenly by hand, serration by serration, further into the conduit opening.

Step 7 – For some plugs at extreme tolerance, a wooden section and mallet may be required.

Step 8 – Air can become trapped inside the penetration. Use a lubricated screwdriver and carefully insert the end between the two plug segments to release the air.

Step 9 – To satisfy certification requirements the flanged edge should be flush against duct.

Step 10 – Inspect the completed seal to ensure that the SLIPSIL plug is correctly inserted and in cases with a ducted pipe or cable that it is correctly fitting.

Testing Standards

CSD SLIPSIL Sealing Plugs have gone through 3 pressure tests at nominal dimensions to determine the pressure ratings for plugs with smallest, medium and largest inlets as well as 3 pressure tests with the minimum pipe diameter and the widest conduit opening to determine tightness and extreme tolerances.

This procedure has to be repeated with the smallest conduit opening and the largest pipe diameter to determine ease of installation. Finally, the largest pipe diameter has to be tested in the widest conduit opening to determine tightness in another extreme condition.

This creates a total of twelve pressure tests for each series to determine the operational tolerances and ease of installation.

• Lloyds Register Witnessed – 2.5 bar pressure test
• TNO Laboratory – Age Testing to 50 years
• BSEN1366-3 European Fire Test – 2 hour fire protection
• NES711 – Low Smoke Index
• NES713 – Low Toxicity Index
• ISO 4589-3 – High Temperature Index
• ISO 4589-2 – High Oxygen Index
