FLANGESEAL Heat Shrinkable Corrosion Protection Sleeve

 

FLANGESEAL

 Heat shrinkable corrosion protection sleeve specifically developed for installation on flanges or mechanical couplings that are already in place.

Product Description: FCWS-F/Flangeseal (US) flange/pipe sealing and protection.

• Construction: Two-layer system
• First layer: Visco-elastic sealant.
• Second layer: Fiberglass reinforced, radiation cross-linked, polyethylene backing.

The FCWS-F/Flangeseal (US) - is a wrap-around heat-shrinkable sleeve, with a specially designed zipper closing system, allowing a fast and simple installation. The fiberglass-reinforce woven backing gives the FCWS-F/Flangeseal (US) a high mechanical resistance as well as a high recovery capacity. In addition to the sleeve, a cardboard sheet is supplied to keep the flange nuts & bolts clean, allowing easy re-entry and disassembly when necessary.

FCWS-F/Flangeseal (US) is installed using standard gas torches. The installation is carried out directly on the cleaned and prepared pipe surface and flange. After preheating, the corrugated cardboard sheet is wrapped around the flange to be sealed. The heat-shrinkable sleeve is positioned centrally over the flange
and closed, using the zipper closure. When heated above 125°C (257°F), the sleeve shrinks tightly around the substrate. During recovery, the adhesive softens and flows to form a tight bond. The bond strength builds up during cool down and is fully retained after completion of the job.

Product Features/Benefits:

• Backing with integrated fiberglass reinforcement making it tough and long lasting. Provides a high recovery capacity.
• 65% shrinkage ratio – conforms to high transitions. Reduces inventory & logistics costs allowing to save money.
• High mechanical resistance backing resists abrasion, impact and penetration.
• No primer required, no drying time and easy application.
• Specially formulated sealant ensures a strong bond & tight seal to virtually any substrate. Maintains its elasticity and sealing characteristics over a wide temperature range.
• Sealing adhesive automatically flows and repairs minor mechanical damages "Self-healing effect."saves money.
• Low preheat sensitivity & proven functionality for faster application, this saving time.
• Zipper closure system for simple & fast installation.
• No special equipment required makes installation fast, easy and keeps installation costs low.
