| PRODUCT
DESCRIPTION |
| HeviCote® is the industry’s leading weight and
protection pipe coating system designed to provide
negative buoyancy and mechanical protection for
pipelines in submarine and wet environments.
HeviCote® uses an impingement process to apply
lightweight, normal weight and heavy weight
concrete coatings, making it ideal for large
diameter pipelines. The product is available in
various thicknesses and densities and can be applied
over anti-corrosion and insulation coatings. |
| FEATURES
AND BENEFITS |
Negative Buoyancy and Mechanical
Protection
- Can be applied in a wide range of densities and
thicknesses to meet project requirements.
- This feature can improve installation, optimize
negative buoyancy and mechanical protection while
minimizing cost.
- Available in thicknesses up to 230 mm (9”)
providing a high level of mechanical protection
and stability.
Value Added Options
- The standard HeviCote® system can be enhanced
further with additional features including bendability
slots, crack inducers, buckle arrestors and
sacrificial anodes.
- Depending on design requirements, HeviCote® can be manufactured with a reinforcing wire cage
or galvanized reinforcing wire mesh.
Excellent Compatibility
- Can be applied over anti-corrosion and insulation
coating systems, enabling project teams to choose
the most appropriate weight and protection
coating system without compromising the long
term corrosion protection of the pipeline.
Global Availability
- Available from a network of coating plants
strategically located across the world to minimize
pipe transportation costs.
- Can be manufactured in a single plant or in multiple
coating plants to improve project logistics.
- High capacity within the Bredero Shaw plant
network allows the client to benefit from single
source advantages, ultimately providing more cost
effective management of pipe coating needs.
