Link-Seals Application & Installation
LINK-SEALS can be installed wherever a pipe passes through a solid structure. The most common use is through concrete walls and or floors.
Below are some typical installations of Link-Seals:
- Manhole Pipe Entry
- Road and/or Rail Crossings
- Bund/ Fire Protection Wall
- Desalination Plants
- Decorative Fountains
- Pool Pipe Penetrations
- Waste & Water Treatment Plants
- Valve Pits
- Refrigeration Pipe penetrations
- Offshore Oil Rigs
- Underground Steel and Concrete Tanks
- In Combination with Century-Line Sleeve Applications
- Precast Concrete Walls, etc.
Link-Seals has even been used to seal pipes coming through steel bulkheads in ships.
For the client that has a “movable” or “for hire” water or wastewater treatment plant, the Link-Seal is the best possible solution because it can be removed and refitted in a timely manner.
1 – Standard Application
Ductile iron, concrete, metal as well as plastic pipes may be hydrostatically sealed within walls to hold up to 20 psig (40 feet of static head).
2 – Below Ground Application
The annular space between carrier pipes passing through casings may be sealed against the entry of water, soil or backfill material.
3 – Existing Work Application
Previously formed concrete can be core-drilled to the required diameter for the optimum Link-Seal sizing
1 – Link-Seal in Combination with Century-Line Sleeves
For the total system approach, metal or non-conductive, Century-Line® Sleeves (with water stops) may be ordered with Link-Seal Mechanical Seals to ensure correct positioning and a watertight seal of the installation within poured concrete walls. (The sleeves need to be installed prior to the concrete pour)
2 – Double Link-Seal for oversize penetrations
When the annular space is larger than the expanded thickness of a single Link Seal
3 – External Divided Sleeve with Mechanical Link-Seal
To seal a pipe penetration that is already in place
4 – Steel Sleeves with Mechanical Link-Seal
Link-Seals are easy to install. Only one contractor with hand tools is required. Click here to view video of installation
Step 1: Center the pipe, cable or conduit in wall opening or casing. Make sure the pipe will be adequately supported on both ends. Link-Seal® Mechanical Seals are not intended to support the weight of the pipe.
Step 2: Adjust the pressure plates just enough so that links move relatively freely. Connect both ends of belt around the pipe.
Step 3: Check to be sure all bolt heads are facing the installer. Extra slack or sag is normal. Do not remove links if extra slack exists. Note: On smaller diameter pipe, links may need to be stretched.
Step 4: Slide belt assembly into annular space. Ensure that both front and back plates are inside the penetration. For larger size belts, start inserting Link-Seal assembly at the 6 O’clock position and work both sides up toward the 12 O’clock position in the annular space.
Step 5: LS-200 thru. LS-315: Using a hand socket allen head or off-set wrench ONLY, start at 12 O’clock. Working in a clock- wise manner, tighten each bolt. Do not tighten any bolt more than 4 turns at a time until links have been uniformly compressed.
Step 6: Make 2 or 3 more passes at 4 turns per bolt MAXIMUM, tightening all bolts clockwise until all sealing elements “bulge” around all pressure plates. On type 316 stainless steel bolts, hand tighten ONLY – do not use power tools.
