Description

Duct Seal HG (Water & Gas) Duct Sealing System for Large Cables and Pipes - ≤2 Bar Pressure Resistance

The Duct Seal HG system is a re-enterable duct sealing solution specifically designed for large, heavy cables and pipes in complex duct scenarios. It effectively prevents the ingress of harmful or flammable gases, liquids, smoke, and vermin, keeping installations safe and secure. Whether used in data centres, substations, or waste-to-energy plants, Duct Seal HG has got you covered.

Features

DuctSeal HG Features

  • Patent Pending Trefoil/Triplex Cable Separation: Our tubular rubber backing system can be configured in continuous strips, rings, or cross shapes, providing optimal support and separation for large cables or pipes. This unique design, suitable for trefoil cables and raceway seals, simplifies installation and meets DSEAR compliance.

  • MEKO-Free, Fybrid, Non-Hazardous Intumescent Sealant: Duct Seal HG uses our advanced Grey Stuff and Red Stuff sealants. These flexible, zero-halogen, MEKO-free sealants ensure safety for installers and the environment alike.

  • Water & Gas Tight: The Duct Seal HG system provides a solid barrier against water and gas, making it perfect for critical infrastructure applications.

  • Toxic Gases Resistant: Specifically designed for the water industry, Duct Seal HG resists gases like methane, chlorine, and hydrogen sulphide.

  • Hydrocarbons Resistant: Designed for petrol forecourt applications, Duct Seal HG withstands exposure to hydrocarbons, making it ideal for installations in areas with chemical agents.

  • Flame Retardant: Duct Seal HG has been tested to UL94:2013 ANSI / UL 94:2018 standards for flame retardancy.

  • Industry Compliant: Duct Seal HG meets standards including DSEAR, WIMES, DCG, APEA, the Blue Book, and ATEX, ensuring suitability for a range of demanding sectors.

  • Microbial Defence: Built-in resistance against fungi and bacteria ensures long-lasting protection in tough environments.

  • Prevents Water Treeing: Duct Seal HG forms a watertight seal, blocking moisture and safeguarding cables from water treeing damage.

  • Low Cable De-Rating: With a 20mm thickness, the thermal resistance is only 5.1 K/W, ensuring the cable maintains its maximum current capacity.

  • MADE IN UK: All Duct Seal HG components are proudly designed and manufactured in the UK, ensuring quality and craftsmanship.

Electrostatic Properties

GreyStuff has been independently tested to assess its electrostatic behaviour in accordance with recognised industry standards for electrical insulation and static charge performance.

Testing was conducted to:

  • BS EN 60079-32-2 / IEC 60079-32-1 (Surface Resistivity – electrostatic hazards guidance)
  • BS EN 61340-2-3 (Volume Resistivity – resistance through material)

Test Results

  • Surface Resistivity: > 2.0 × 10¹³ Ω/sq (at 25% RH)
  • Volume Resistivity: > 1.7 × 10¹² Ω·m
Applications

Where DuctSeal HG is Commonly Used

Data Centres: Provides a reliable seal around large cables in critical data infrastructure, protecting against external environmental threats.

Substations: Effectively seals ducts in electrical substations, blocking harmful substances from entering.

Pumping Stations: A solution for the water industry where toxic gas resistance and a secure, water-tight seal are essential.

Waste-to-Energy Plants: Built for harsh environmental conditions, ensuring long-term duct integrity in waste-to-energy facilities.

Wind Farms/Turbines: Offers robust protection for renewable energy installations that operate in exposed environments.

Electrical Utilities: Ensures safe and secure duct sealing for various electrical utility applications.

Rail Industry: Meets Network Rail standards, making it ideal for rail infrastructure projects.

How To Use
  1. Abrade the First 20mm: Lightly abrade the initial 20mm of the duct and cables to remove grease, old sealant, and dust, creating a clean surface for the sealing compound.

  2. Clean the Duct and Cables: Remove all debris, grease, and dirt to ensure the Grey Stuff or Red Stuff sealant bonds well.

  3. Insert Larger Tubes/Sleeves: Begin with the larger tubes or sleeves, inserting them into the duct to separate the cables from the inner duct wall. For trefoil cables, join the larger tubes to create a cross shape to maintain separation among the cables.

  4. Fill Smaller Gaps: Use additional tubes to fill any remaining gaps, forming a solid support structure.

  5. Adjust Tube Depth: If the tubes are too deep, use long-nose pliers to position them approximately 20mm from the duct edge.

  6. Apply the Grey Stuff or Red Stuff Sealant: Begin at the bottom and work upwards for complete coverage.

  7. Finish with the Magic Sponge: Wet and squeeze the Magic Sponge, then dab it over the sealant to ensure it adheres to both the cables and duct, leaving a clean finish.

  8. Complete: Your installation is now secure and sealed.
