Project Data

Project Details

The TransCanada Keystone Pipeline is over 2,100 miles stretching from Hardesty, Alberta, Canada to Houston, Texas. The massive 36” crude oil pipeline is one of the world’s largest pipeline projects which took 5 years to construct.

The project was constructed in Spreads (approx. 100 miles each) with most contractors selecting Protal 7200 as the girth weld coating. Protal 7200 has outstanding physical properties and fast cure ability, which allowed the contractors to use the same coating for the protection of all weld joints including girth welds, tie-ins and bore joints, as well as “holiday” repairs.

Protal 7200 is a two-part, 100% solids epoxy coating that can be applied in one coat up to 50 mils. Additionally, it has high impact and abrasion resistance for directional drill applications.

Furthermore, the extremely fast cure makes it ideal for tie-ins and “holiday” repairs. Using Densoʼs “Accelerated Cure Specifications for Repairs”, the contractors were able to achieve a 5 minute cure with the Protal 7200 when repairing “holidays” in the FBE during the pipeline “lowering-in” process.

Unlike FBE, which requires expensive and heavy equipment, Protal 7200 only requires a brush or roller to apply. The contractors were able to coat up to 150 weld joints per day without the costly risk of downtime due to equipment failure. Due to these cost savings, Protal 7200 is ideal for a variety of field applications including girth welds, tie-ins, HDD applications, station piping, fittings and repairs to FBE.
