Flexclad Heat-Shrinkable Tape Wrap for Pipe Bends

FLEXCLAD Heat-Shrinkable Tape Wrap for Pipe Bends

Hand-wrapped, heat-shrinkable corrosion protection tape.

Product Description:
Construction: Multi wrap construction:
Adhesives: Semi-crystalline mastic sealant (Flexclad), High-shear strength copolymer adhesive (Flexclad-II-C30).
Backing: Flexible, radiation cross-linked, low density polyethylene.
FLEXCLAD tapes are stretchable, hand-wrapped, heat-shrinkable tapes used for corrosion
protection of pipe bends and also for small diameter straight pipes in distribution networks.
FLEXCLAD is available in 2 mechanical classes: B30 = FLEXCLAD; C30 = FLEXCLAD-II-C30.

The installation is carried out directly on the cleaned and prepared pipe surface without any primer. During installation, FLEXCLAD(-II) is to be wrapped spirally around the bend with a 50% overlap. The carrier is heated and shrinks tightly around the substrate; at the same time, the sealing adhesive melts and is forced into all surface irregularities, forming a thorough coating and a complete bond with the substrate.
