The nuclear industry represents one of the most demanding environments in terms of manufacturing, control, and reliability of mechanical components. From the design and construction phases to plant operation, the integrity of each component is crucial to the safety and efficiency of the entire system.
These elements must withstand extreme conditions of pressure, temperature, radiation, and prolonged continuous operation cycles. Therefore, ensuring geometric and dimensional accuracy alone is not sufficient; it is equally essential to guarantee long-term structural strength, load stability, and the absence of internal or manufacturing defects.

Once the most suitable technology has been selected for the main machining operation, it is essential to have a partner providing the complementary services required to optimise the production process. From raw material management and technical planning to quality control and logistics, these services ensure efficiency, reduce costs, and help meet deadlines. A comprehensive approach enhances the reliability of the final product and maintains competitiveness within the industrial sector.

At Talleres Mecánicos ARRI, we continue to strengthen our machining capacity to offer more complete solutions to our customers. Over the years, we have consolidated a highly specialized machine inventory, with a range of Trevisan machining centers that allows us to work with different sizes and levels of complexity in valve components.

At Talleres Mecánicos Arri, welding is integrated into machining services with standardised TIG and MIG-MAG welding processes by ASME Section IX. This translates into significant time savings and improved efficiency. It is common for parts to have imperfections or require additional materials on the piece being machined. The ability to perform this work directly on the production line adds value as a supplier, optimising the process and reducing lead times and costs for clients in energy and petrochemicals.

Butterfly valves are considered essential components within the industry for flow control, and their accurate machining is crucial for their efficient functionality. With over three decades of experience, our firm stands out in the machining processes for producing top-quality butterfly valves.

At ARRI Machining, where excellence in machining merges with innovation, we recognise the complexity of machining parts, especially regarding large valves and valve bodies. This procedure, a secondary operation with high added value, not only completes the production of the parts but also involves strict quality control.
