Global Transmission Sleeve

The GTS-50 system provides superior corrosion protection and excellent bonding on pipelines operating up to 55°C. GTS-50 has been designed with a unique adhesive technology that remains open longer than traditional adhesives. GTS-50 is a cost effective alternative for lower temperature pipelines while maintaining the highest levels of corrosion protection.

Flexible Installation

  • GTS-50 can be used as either a 2-layer or 3-layer sleeve system with the same low pre-heat temperature
  • For added flexibility, the sleeve can be supplied as bulk rolls or pre-cut to the required pipe size

Saves Time & Money

  • Lower pre-heat means less time heating
  • Offers a cost-effective solution without compromising pipeline protection

Unique Adhesive Technology

  • Allows for lower installation pre-heat temperatures and superior bonding to PE, PP and FBE coatings
  • Adhesive has been formulated to bond directly to the main line coating; epoxy is applied to the steel only

Superior Force Cured Epoxy

  • Proven method of force curing the liquid epoxy to the steel allows the installer to “pre-inspect” the joint prior to sleeve application
  • Force cured epoxy cannot be displaced during the aligning and shrinking stages of the sleeve installation

Long Term Corrosion Protection

  • Provides a protective coating with the structural integrity of a seamless tube, providing excellent resistance to cathodic disbondment and excellent durability against abrasion and chemical attack
