DENSO 60 Tubular Heat Shrink Sleeve (DENSO 60THSS)
Description: Denso 60THSS is a one piece two layer field joint coating system designed for
corrosion protection of pipelines that operate at ambient temperature.
Composition: Two-layer structure
First layer: Low pre-heat modified bitumen sealant adhesive.
Second layer: Thick-wall irradiated cross linked Polyolefin.
Characteristics: Denso 60THSS is compatible with standard pipe coatings, and can also be used for
coating bare, replacement pipe sections and large radius bends.
Purpose formulated compound gives excellent adhesion results, excellent
resistance to cathodic disbondment, and long term corrosion protection.
The high performance backing is engineered for standard or high soil stress
environments.
The installed sleeve offers the structural integrity of a seamless tube and offers
superior resistance against abrasion and chemical attack.
The sealing adhesive automatically flows and repairs minor mechanical
damage. This self-healing effect saves extra intervention steps.
Stable in composition and plasticity over a wide temperature range.
Non-hardening and non-cracking. Tough, but flexible even at low temperatures!
Accommodates vibration and extreme movement of substrate.
Highly resistant to mineral acids, alkalis and salts.
Will adhere and remain attached to all cleaned, sound, dry metal surfaces.
No special equipment or skills required
Uses: Denso 60THSS is a one piece heat shrinkable tubular sleeve, ready to fit
assembly, for the corrosion protection of field weld joints in distribution and
transmission systems.
Surface
Preparation
and Application:
Installation is carried out directly on the cleaned and dried (pre-heated) pipe
surface (as per application instructions), without any primer being required. The
system is designed to be applied with minimum pre-heating and is ideal for small
to medium diameter distribution and transmission systems.
The tubular heat shrink sleeve is placed onto the pipe prior to final welding, and is
shrunk to form a tight fit around the joint. During recovery, the adhesive softens
and flows to form a perfect bond with the pipe surface providing protection against
corrosion. The irradiated polyolefin outer layer forms a tough barrier against
mechanical damage and moisture transmission.
