Link-Seal Mechanical Seal
Link-Seal Mechanical Seal
Link-Seal is designed to create an instant & secure, leak-proof barrier around pipe penetrations. Century-Line Sleeves, Cell-Cast Discs, Steel Sleeves & External Sleeves can be used in combination with Link-Seal Mechanical Seal.
Projex Group have been supplying Link-Seals, Century-Line Sleeves, Cell-Cast Discs and other products into small & major infrastructure projects. These include Gas Plants, Oil Refineries, Hospitals, Water & Waste Treatment Plants where the sealing of these penetrations is extremely critical & of the highest importance.
Link-Seal
Link-Seals are supplied in a belt form with a series of interconnecting rubber links, pressure plates and bolts that – when tightened – create a seal between the pipe and core hole. There are different Link-Seal models to accomodate an array of applications.
- Link-Seals are resistant to water, oil, aggressive chemicals and fire
- They are suitable for PVC, Copper and Steel pipes
- Comes in many different sizes to accomodate pipes ranging from 10mm to 3.6m in diameter
The Link-Seal system offer an INSTANT seal and unlike most grouts, foams, epoxy’s or cementitious products they do not shrink whilst curing & require no maintenance afterwards.
The Link-Seals can easily be checked, adjusted, removed and reinstalled following initial installation.
Century-Line Sleeves features
- Century-Line Sleeves are the quickest, easiest & most efficient way of creating the perfect circular holes in poured concrete barriers
- They are installed onto the formwork prior to the concrete pour
- Manufactured from HDPE, they are lightweight and also adjustable to suit the wall thickness
- Suitable for creating holes ranging from 50mm-635mm
Benefits
- Create perfect round sleeved hole in concrete poured barriers
- Positive hydrostatic seal
- Easily installed - only one worker and no special tools
- Adjustable to wall thickness, can be cut on-site
- Nailer-end caps to position sleeve precisely
- Resistant to water migration, acids, alkalis and other organic solvents
- Never rust, corrode or degrade
- Suitable for temperature between -40C to 66C
Cell-Cast® Interlocking Hole Forming Discs features
- Cell-Cast Discs are used to create a larger round hole in poured concrete surfaces ranging from 743mm to 1645mm
- They are installed onto the formwork prior to the concrete pour
- They are manufactured from thermoplastic, are durable & lightweight
Benefits
- Consistently produces dimensionally accurate openings
- Easy to install
- Complete assembly accomplished in minutes
- Reduces material costs by 30 % to 50 %
- Cuts labor costs by 50 % to 70 %
- Minimises freight and handling charges
- Lightweight
- Sized to work with Link-Seal Mechanical Seal
Steel Sleeves features
- Steel Sleeves are used for non-standard installations where exposed to hydrocarbons, extremely high temperatures, aggressive chemicals or a fire rating is required
- The casting in of a Steel Sleeve to create the penetration is part of the solution, next is to install the correct Link-Seals for the nominated chemical or desired rating.
Benefits
- Create a smooth and perfect circular penetration
- Protects the substrate core hole
- Resistant to hydrocarbons, high temperatures and aggressive chemicals
- Can be used when a fire rating is required
- Can be used with Link-Seal Mechanical Seal
- Very easy to install
- Available in a wide range of sizes
- Prevents liquid migration
External Sleeves features
- The External Sleeves solve core hole penetration seals
- They are bolted to either side of a wall where a cable or pipe protrudes & is designed to overcome installation issues such as the following; non-centered pipes or cables, oversize penetrations, incorrect core hole installations and many more
- The External Sleeves are available in 2 versions for new and retrofit applications.
Benefits
- Can be fitted around pipes or cables that are already installed and in use
- Suitable for pipes from 50mm to 1600mm OD
- Stainless steel base and collar for longevity
- Easy and Quick to install (no special tolls required)
- Can be re-fitted and re-used
- EPDM or SBR rubber gasket seals to substrate
- Two or more penetrations can be fitted on a single base plate
- Can be used with Link-Seal Mechanical Seal
