HTLP80 - 3 layer Wrap-around field-joint coating (with epoxy)

Description
Three-layer field-joint coatings (HTLP) are the toughest field applied coating systems.


Common Applications

Compatible with all commonly used pipe coatings, including PE, coal tar enamel, coal tar epoxy, and fusion-bonded epoxy.

Highlights
• Fully resistant to shear forces induced by soil and thermal movements.
• Sleeve applied over wet epoxy, with no curing or waiting times.
• Superior cathodic disbondment performance and hot water immersion resistance.
• Fully reconstructs three-layer coating at all girth welds for continuous and homogeneous performance on pipelines coated with 3LPE.
• Low preheat requirements.

Maximum Temperature: 80 ºC - 176ºF
