3M™ Scotchkote™ Pipeline Protection Products
Additional Information
Major oil and gas companies around the world have selected Scotchkote coatings to be their
primary corrosion defense for protecting their pipeline investment. Scotchkote fusion bonded
epoxy coating is tough. Durable. Field-proven. It's more than just a superior pipe coating - it's a
vital element in the gas and oil pipeline network.
Scotchkote fusion bonded epoxy coating has proven so reliable, in fact, that more than 62,000
miles (100,000 km) of pipe treated with Scotchkote coating has been installed throughout the
world. Typical pipeline applications include internal and external coatings for natural gas,
petroleum, water and sewage, as well as pipe systems for refineries, petrochemical plants,
power plants and paper mills.
Worry-Free Service From Day One:
From the moment a pipe is coated with our Scotchkote™ fusion bonded epoxy coating and
installed in the ground or in the sea, maximum corrosion protection is assured. The unique
chemical characteristics of our coating are carefully engineered for optimum protection of metal -
even in the harshest environments: saltwater, wastewater, petrochemicals and corrosive gases.
Scotchkote fusion bonded epoxy coating protects against soil stress, bacteria and fungus attack,
soil acids, alkalis - all the corrosive elements associated with underground or underwater use.
The coating's excellent physical properties minimize damage during transit, installation and
operation. It requires very low levels of cathodic protection, even after extended periods of time.
The Features You Demand:
Resists cathodic disbondment
Helps keep protective current density requirements low
Good chemical resistance
High adhesion and toughness
Balanced application characteristics for all pipe sizes and types
Can be machined by grinding or cutting to meet tolerance requirement
