Heat Shrinkable Sleeves (HSS) represent the industry standard for field joint corrosion protection and coating rehabilitation on oil, gas, and water pipelines. Engineered from a cross-linked polyolefin backing coated with a hot-melt adhesive, these sleeves shrink under heat to form a tight, impervious seal over the steel pipe surface and adjacent factory coatings. They offer exceptional resistance to soil stress, mechanical forces, and cathodic disbondment, ensuring long-term pipeline integrity under demanding service conditions.
