FRDS is designed for corrosion protection of field girth weld joint of buried and exposed steel pipelines, also for pipe bends or pipe elbow.FRDS is designed to provide a continuous, holidayfree,permanent barrier, which affords long-term protection for high-temperature pipelines operating.

FRDS consists of a radiation cross linked low density polyethylene backing, coated with a hot sensitive adhesive which effectively bonds to steel substrates and common pipelines coatings, including polyethylene and fusion bonded epoxy. The product can be conveniently used for corrosion protection of steel pipe, especially for protection and repairing pipelines, fittings, elbows, bends and other irregular configurations.

Construction: two layer system:

First layer: High shear strength copolymer adhesive.

Second layer: Radiation cross-linked, high density polyethylene

Features:

Easy installation, reliable usage properties

Good resistance to mechanical damage and liquid pressure. Excellent sealing property.

Resistant to bacteria and chemical.
