As a manufacturer of thermoplastic composite pipes (TCP), we want to highlight the publication of NEN 3650-6, a new Dutch standard defining requirements for spoolable thermoplastic composite pipes in onshore applications.
Thermoplastic composite pipes have been produced in the Netherlands for many years, and it was time to update the existing NEN 3650 series with a specific standard which accounts for their different stiffness, strength, and chemical resistance characteristics.
The introduction of NEN 3650-6 provides a formal framework for the design, installation, and maintenance of TCPs in the Netherlands, ensuring they meet safety and performance criteria comparable to traditional materials and thus allowing operators, designers, and installation contractors to use TCP in their projects.
TCP offers numerous advantages over traditional steel pipelines, making it particularly suitable for transporting CO2 and hydrogen, in both onshore and offshore applications. The technology can be produced in long, continuous lengths, reducing the need for joints and welds. The materials used are inherently resistant to corrosion, extending the pipeline's lifespan. TCP’s lightweight construction means it can be installed using lighter installation equipment which further reduces the overall costs, and the carbon dioxide and nitrogen emissions of pipeline projects.
Key aspects of the standard include:
- Defining design methods and allowable limits: Accounting for time-, temperature-, and deformation-dependent properties.
- Safety requirements: Guidelines for the safe construction, operation, and maintenance of TCP systems.
- Residual strength assessment: Allowing remaining lifetime assessment at the end of the product’s design life.
The creation of NEN 3650-6 is a major milestone for the industry, unlocking opportunities for TCP to be deployed in onshore applications. The new standard will streamline compliance, simplifying the regulatory landscape for manufacturers and operators; encourage the adoption of advanced materials like TCP in the Netherlands; and enhance safety and reliability across the industry.
We look forward to the opportunity to collaborate with more operators and other technology providers to make composite pipes accepted in more countries in Europe and worldwide.
