Structured-Wall Piping Systems

Structured-wall piping systems are designed to provide enhanced strength and durability while maintaining a lightweight profile. This makes them ideal for underground applications where long-term performance and ease of installation are critical.

Material Specifications

The PD CEN/TS 13476-4:2025 standard covers three primary materials:

• Unplasticized Poly(vinyl chloride) (PVC-U): Known for its rigidity and chemical resistance, PVC-U is a popular choice for a variety of piping applications.
• Polypropylene (PP): Offers excellent resistance to chemical and environmental stress, making it suitable for harsh conditions.
• Polyethylene (PE): Renowned for its flexibility and impact resistance, PE is ideal for installations requiring adaptability to ground movement.

Assessment of Conformity

The standard provides a detailed framework for assessing the conformity of structured-wall piping systems. This ensures that all products meet the necessary quality and performance criteria before they are deployed in the field.

Ensuring Quality and Safety

By following the assessment guidelines, manufacturers and installers can ensure that their products are safe, reliable, and compliant with industry standards. This not only enhances the reputation of the products but also provides peace of mind to end-users.

Who Should Use This Standard?

The PD CEN/TS 13476-4:2025 is an invaluable resource for:

• Engineers and Designers: Ensures that designs meet the latest standards and are optimized for performance and safety.
• Contractors and Installers: Provides clear guidelines for installation, ensuring compliance and reducing the risk of errors.
• Quality Assurance Professionals: Offers a framework for assessing product quality and conformity, ensuring that all products meet the required standards.

Conclusion

The PD CEN/TS 13476-4:2025 is an essential standard for anyone involved in the design, installation, and maintenance of non-pressure underground drains and sewers.
