Concrete coated pipe types and dimensions

Concrete coated pipes are commonly used in subsea environments and are manufactured in various dimensions and with multiple coating options to meet different environmental demands. These pipes can be customized with varying weights, thicknesses, and densities of concrete coatings, as well as additional anti-corrosion and insulation coatings to enhance their durability and performance underwater.

Below are the typical specifications for concrete-coated pipes:

Mother Pipe Standards
Concrete-coated pipes are usually manufactured according to widely recognized standards to ensure structural integrity and suitability for subsea applications. Common standards include:

API 5L: Ranges from Grade B up to Grade 80.

ISO 3183: Covers Grade L245 to Grade L555.

Diameter Range
Concrete-coated pipes are available in diameters ranging from:

6 inches (150 mm) to 60 inches (1500 mm), accommodating a wide range of applications from small pipelines to large subsea installations.

Pipe Wall Thickness
Pipes come in various thickness schedules to meet specific strength and pressure requirements:

SCH 20: Standard for low-pressure applications.

SCH 40: Medium-duty thickness, suitable for moderate pressure and structural needs.

SCH 80: Heavy-duty thickness, ideal for high-pressure and high-strength applications.

Length
Concrete-coated pipes are generally manufactured in lengths of:

Up to 12 meters, which is a typical length for easy transport, handling, and installation in subsea environments.

Concrete Coating Specifications

Thickness: Concrete coatings can vary depending on the required level of protection and weight to provide stability on the seafloor.

Density: Higher-density concrete can be used for pipes in environments where additional weight and stability are required.

These specifications ensure that concrete-coated pipes can be adapted to various subsea conditions, providing protection, durability, and stability for long-term applications.
