HS-3402
Product HS-3402
SHAIC HS-3402 is a heat-shrinkable wraparound sleeve
designed for corrosion protection of field-welded joints of plastic coated steel pipelines. It has a thick crosslinked polyethylene backing coated with butyl rubber based mastic adhesive. Mastic shall depend on project requirements. When heated the backing layer shrinks flows and forms a reliable corrosion protection seal onto metal and adjacent coating surfaces.
Long-term Corrosion Protection
After heating, formed corrosion protection seal & strong backing provides outstanding waterproofing effect
and high chemical resistance. SHAIC HS-3402 resists impact, abrasion and ultraviolet light. Free from
penetrating pinholes due to multi-layered structure. Excellent resistance against cathodic disbondment,
dielectric breakdown.
Simple Application
No special skills and equipments are needed. Sleeve is installed in minutes with a propane torch.
Wrap the sleeve around foreign matters-free, preheated surface. Fix the center of preheated patch closure on the overlapped end and start heating the sleeve in the center.
Move the torch around pipe circumferentially to heat the left and the right half of sleeve. Finish off by heating vertically over the entire sleeve to ensure a uniform adhesion and by using a roller or gloved hands to remove wrinkle and air.
Bulk Rolls
SHAIC HS-3402 is supplied in bulk rolls, which is cut in the field for any size of pipe. No need to drive to
warehouse and just cut customized length in the field in time that reduces inventories and saves the
cost & time.
