Priority to Structural Safety and Regulatory Compliance
Overview of the NTC 2018 Standards and Related Eurocodes

The NTC 2018 (Technical Standards for Construction) are the main regulatory reference in Italy for the design, verification, and testing of structures, including those intended for the storage of liquids or bulk materials, such as silos and tanks. By integrating the principles of the Eurocodes, the NTC ensures a scientific and rigorous approach to structural safety, seismic resistance, and long-term durability of constructions.

Designing and building according to the NTC 2018 means ensuring that every structure can reliably withstand the expected static and dynamic actions, including internal pressures, wind and snow loads, seismic actions, and instability phenomena. The standards also require careful evaluation of the mechanical properties of materials, adopted construction techniques, and interaction with the ground.

Structural verifications are mainly based on the following Eurocodes:

  • EN 1991 for the definition of loads and environmental actions;

  • EN 1993 for the design of steel structures, including instability and fatigue phenomena;

  • EN 1998 for seismic design of industrial structures.

The joint application of the NTC and the Eurocodes ensures that the project complies with the highest European standards of safety, reliability, and sustainability.
The design process includes detailed structural analyses, FEM modeling, document control, and, where required, validation by bodies responsible for seismic and structural verification.

Silos and tanks built in compliance with NTC 2018 thus represent not only a safe and long-term investment but also a clear indicator of design quality and compliance with current national and European regulations.

What Regulatory Compliance Means in the Construction of Industrial Tanks

Structural Design (NTC 2018 + Eurocodes)
Compliance with NTC 2018 and the Eurocodes ensures that tanks are designed to withstand static, dynamic, and seismic loads according to the highest structural safety standards established by European and Italian regulations.

Leak Prevention System
All the cited standards include specific measures to prevent accidental leaks through the use of multiple walls, safety devices, automatic monitoring systems, and inspection plans.

Monitoring and Testing System
It is mandatory to perform functional and structural verifications, including leak tests, pressure tests, and final inspections, to ensure the suitability of the tank before commissioning.

Periodic Inspections and Maintenance
The regulations require tanks to undergo regular inspections by qualified technicians or notified bodies, with the frequency depending on the type of service and risk category.

Technical Documentation and Traceability
Each tank must be accompanied by complete documentation certifying the materials used, welding processes, inspections performed, and maintenance plans, ensuring full traceability and regulatory compliance.
