| PRODUCT
DESCRIPTION |
| Compression Coat is the pipeline industry’s leading
coating system for projects requiring rapid mobilization
or coating near the right-of-way. This concrete
coating system is designed to provide negative
buoyancy and mechanical protection for
pipelines in subsea and wet environments.
Compression Coat uses a side-wrap application
process making it ideal for both small and 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 150 mm (6”) providing
a high level of mechanical protection and stability.
- Offers a consistent and uniform thickness and
minimum weight variance from specifications.
Excellent Compatibility
- Can be applied over anti-corrosion and insulation
coating systems, enabling project teams to choose
the most appropriate weight coating system without
compromising the long term corrosion protection of
the pipeline.
Value Added Options
- The standard Compression Coat system can be
enhanced further with additional features including
bendability slots, crack inducers, buckle arrestors and
sacrificial anodes.
Global Availability
- Available from a network of fixed coating plants
strategically located across the world to minimize
pipe transportation costs.
- Bredero Shaw has unique portable Compression Coat
facilities that can be mobilized in a short period of time
to meet specific project requirements. This can significantly
reduce pipe transportation and handling costs.
- High capacity within the Bredero Shaw plant network
allows the client to benefit from single source advantages,
providing more cost effective management of
pipe coating needs.
