FRDP Heat Shrink Sleeve
FRDP Heat Shrink Sleeve


FRDP wraparound heat shrinkable sleeve (HSS) with a separate closure patch is mainly used for field joint coating of underground 3LPE coated steel pipelines and thermal insulated pipelines.

FRDP heat shrink sleeve bonds the steel substrate, FBE primer and plant-applied polyethylene coatings excellently to form a continuous and durable corrosion protection system on the pipeline.

CYG 80℃ FRDP heat shrink sleeve is Germany DVGW certified.
