Fields of application
- For sealing wall penetrations of gas, water, sewage pipes and cables (considering the calculation basis and the suitability of the product on site)
- Tank embeddings
- Casing pipe seals
Description
The radial expansion of the rubber parts ensures a permanent, pressure-tight and secure sealing of the annular space. For particularly thin-walled plastic pipes such as pre-insulated, flexible casing and corrugated pipe systems, a Compakt Temp or Compakt Super Soft is recommended.
Notes
- The surface of the core drilled holes should be coated to protect the reinforcement from corrosion. Therefore we recommend ProteX epoxy resin or ProteX sealant. The specified values for the pressure tightness are valid at 23 °C. For different, higher permanent operating temperatures, changing temperatures and permanent pressure, it might be necessary to fit an ejection safety device.
- Please be sure to ask us in advance about the technical feasibility of planned applications for which there is no description (e.g. applications in the biogas or food sector).
The purchaser bears the sole risk for use in Fields of application not described, we do not accept any guarantee for the suitability of the product.
Technical Information
Type selection
The suitable LINK-SEAL® for the application results from the thickness of the annular space between the casing pipe (wall sleeve) and carrier pipe. The perfect LINK-SEAL® is smaller than the annular space in a non-tensioned condition and larger in tensioned- condition.
To calculate the appropriate LINK-SEAL® annular space seal, use our online calculation program or the type selection as a basis for calculation. This is available for you to download online as a PDF.
Original LINK-SEAL® Modular Seal
Manhole sealing
If LINK-SEAL® modular seals are used for a penetration in a curved wall (e.g. manhole sealing), it must first be checked beforehand whether a sufficiently large effective sealing surface (Te) is available.
The effective wall thickness can be determined by scale drawing or by using the following formula. It must be greater than or equal to the required minimum effective wall thickness of the selected LINK-SEAL® type.
LINK-SEAL® | Type required Minimum wall thickness |
---|---|
LS 200 - LS 275 | 75 mm |
LS 300 - LS 315 | 100 mm |
LS 325 - LS 360 | 120 mm |
LS 400 - LS 475 | 140 mm |
LS 500 - LS 650 | 150 mm |
LS 700 | 200 mm |
The determined effective sealing surface (Te) must be at least as large as the required minimum wall thickness for the selected LINK-SEAL® type. If the effective sealing surface (Te) is at least 40 mm (for core holes from Di 800 mm at least 80 mm), alternatively a Compakt seal can be selected.
Legend:
Te = Effective sealing surface available
t = Wall thickness
r = Outer diameter
c = Inner diameter core hole / opening
