Quick Information

  • Place of Origin: Korea
  • Model Number : SHAIC HS-340

Description

Shaic HS-340 is a heat-shrinkable wraparound sleeve designed for corrosion protection of field-welded joints of plastic coated steel pipelines. It has a thick cross linked polyethylene backing coated with butyl rubber based mastic sealant or hot melt adhesive. Hot Melt or Mastic shall depend on project requirements. When heated the backing layer shrinks and the sealant flows and forms a reliable corrosion protection seal onto metal and adjacent coating surfaces.

Cut Sleeve is normally supplied with separate Patch Closure, which is coated with a high shear-strength adhesive; however, there are different types and sizes to comply with individual requirements. It is supplied in bulk rolls as well, and has super-heavy duty, heavy duty and regular thickness.

Long-term Corrosion Protection

After heating, formed corrosion protection seal & strong backing provides outstanding waterproofing effect and high chemical resistance.
SHAIC HS-340 resists impact, abrasion and ultraviolet light. Free from penetrating pinholes due to multi-layered structure. Excellent resistance against catholic disbandment, 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 pope circumferentially to heat toe 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-340 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.
