Nassguard supplies the Viscotaq Casing End Seal System in Jeddah to protect the point where a carrier pipe enters its surrounding casing. This vulnerable interface needs a continuous seal to prevent water infiltration and associated corrosion.
The Denso VISCOTAQ™ Casing End Seal System combines mouldable mastic, visco-elastic wrapping and protective glass outerwrap. It accommodates off-centre carrier pipes and can serve new installations or existing casings. Nassguard supplies requirements across Saudi Arabia, including Jeddah, Riyadh, Dammam, Jubail and Al Khobar.
The Viscotaq Casing End Seal System creates a protective transition between the casing pipe and carrier pipe. ViscoMastic fills and profiles the casing-end gap, ViscoWrap forms the corrosion-protective layer, and Denso Glass Outerwrap provides external protection.
A useful feature is its adaptability: the carrier pipe does not need to sit centrally inside the casing. The system also accommodates suitable arrangements containing multiple internal pipes, making it practical for irregular casing-end geometries.
The system combines conformable sealing materials with a reinforced outer covering.
Pipeline casing end seals should match the actual pipe geometry, exposure and maintenance requirements.
For projects in Jeddah, Dammam, Jubail and Al Khobar, provide details of groundwater exposure and access. Engineering and procurement teams in Riyadh can include drawings when requesting materials for remote sites.
Careful preparation and complete filling help avoid concealed pathways for water.
Resolve venting, drainage and any pressure requirements during project design. A casing water-infiltration seal should not automatically be treated as a pressure-retaining closure.
Inspect the complete casing seal, including its junctions with both pipes.
Nassguard supplies Viscotaq casing-seal components for Saudi project and maintenance requirements. Clear site information helps establish an accurate quotation.
1. What does the Viscotaq Casing End Seal System protect?
It protects the carrier-pipe-to-casing interface against water infiltration and corrosion.
2. Must the carrier pipe be centred?
No, the system accommodates off-centre carrier pipes.
3. Can it seal casings containing several pipes?
Yes, it supports suitable multiple-pipe configurations.
4. Can it replace an existing casing-end seal?
Yes, following assessment and preparation of the existing installation.
5. What are the main components?
The system combines ViscoMastic, ViscoWrap and Denso Glass Outerwrap.
6. Does installation require curing time?
Yes, the glass outerwrap requires curing before the completed protection is subjected to relevant handling or loading.
7. What information should I send Nassguard?
Provide pipe dimensions, offsets, photographs, operating conditions, quantities and delivery requirements.
The Viscotaq Casing End Seal System in Jeddah offers an adaptable solution for protecting casing entrances, including off-centre and multiple-pipe arrangements. Its layered construction combines gap filling, corrosion protection and an external protective shell.
Reliable installation depends on sound preparation, complete profiling and careful termination detailing. Contact Nassguard with your project requirements for supply across Saudi Arabia, including Riyadh, Dammam, Jubail, Jeddah and Al Khobar.
