Heat shrink cuff HTLP-60
Heat shrink cuff HTLP-60 is a system that provides corrosion protection to welding joints of underground pipelines operated under 60°Ñ.
The cuff is based on radiation grafted polyolefine covered with a hot-melt adhesive. The cuff has high shear resistance. The two-pack primer supplied with the cuff is made of epoxy resin and a hardener.
