Description
Anti-corrosion heat shrink sleeve is made of radiation cross-linked polyolefin, extruded inside a layer of hot melt adhesive. It effectively protects exposed metal by sealing it against water, corrosive substance. It is typically used, out of corrosion resistant or heat preservation purposes, to protect the the welding repaired mouth of underground or overhead steel tubes for oil and gas transportation and water and pollution discharge.Additionally, it also finds application in sealing pipe flange and hoop against corrosion.
Features
Excellent bonding capacity, compatible with different materials like steel, epoxy coating, 2PE, 3PE, 3PP, FBE,heat preservation jacket
Long service life, good sealing capability
Simple installation, quick wrap, beneficial to construction
Preheat the epoxy primer to 40~60℃and begin the shelling-out process. Applicable to both dry and wet film construction.
Standards:SY/T 0413-2002:GB/T 23257
