How ThermoTRON® is Made

ThermoTRON®, Mark Tool & Rubber’s revolutionary thermal insulation system, is the ideal solution for all of your offshore protection needs. In order to best help you understand the benefits of this powerful coating, we decided to break down exactly how it’s made for you. 

The Layers

In order for ThermoTRON® to successfully insulate and protect your structures from damage, it is constructed with three critical layers:

1. High-density, high-temperature elastomeric layer

The outermost layer of ThermoTRON® is made up of extruded ThermoTRON®, and its thickness depends on the service conditions. This layer is specially made to offer anticorrosive and mechanical protection for offshore structures and pipelines, along with high-caliber thermal insulation properties.

2. Bonding agent layer

ThermoTRON®’s middle layer is made up of a bonding agent that binds the top coat to the core corrosion-resistant layer.

3. Corrosion-resistant layer

After the pipe has been steel grit blasted, the innermost layer of ThermoTRON® covers it with a special film that’s resistant to chemical attacks and cathodic disbondment.

Joint Insulation System

The ThermoTRON® field joint insulation system is created using half shells that are pre-manufactured from its compound. These half shells are then bonded to the weld joint using a bonding agent, and then banded together so that the sleeves stay in place during the curing process.

Field Joint Installation Process

During the field joint installation process, the half shells are sized to fit the pipe diameter, cut back, and an epoxy is applied both outside of the pipe and inside of the half shells. The top is installed before the bottom half shell, then secured in place with a banding agent and wrapped with plastic wrap to hold in the adhesive.

With over 60 years of experience built into its technology, Mark Tool has designed ThermoTRON® to perform in the most extreme environments, offering you protection for at least 30 years.
