Introduction
SHAIC HS-3401 three-x-layered heat shrinkable wraparound sleeve is designed for welded joint protection with epoxy primer of plastic-coated steel pipelines. It has a thick cross-linked polyethylene backing coated with heat sensitive adhesive and two-part of liquid epoxy primer. Apply epoxy primer to the pipe surface, adhesive then flows and forms a reliable corrosion protection seal onto epoxy and adjacent coating surfaces.

Long-term Corrosion Protection
After heating, formed corrosion protection seal and strong backing provides outstanding waterproofing effect and high chemical resistance. SHAIC HS-3401 three-x-layered corrosion protection system resists impact, abrasion, and ultraviolet light as well as excellent resistance against cathodic disbondment and dielectric breakdown.

Bulk Rolls
SHAIC HS-3401 is supplied in bulk rolls, which is cut in the field for any size of pipe. No need to drive to the warehouse and instead, just cut to customized length in the field that reduces inventories and saves cost and time.

Flexible Installation
SHAIC Heat Shrinkable sleeve can be used in three-x-layered or two-x-layered installations depending on your specific project requirement. Please contact our representative for appropriate installation. Apply epoxy primer over preheated surface free from foreign matter. Wrap the sleeve around the pipes. Fix the center of the preheated patch closure on the overlapped end and start to heat sleeve in the center. Move the torch around pipe circumferentially to heat the left and the right side 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.
