The ESP series systems are designed to perform circumferential welding operations between rounded and ferrule bottoms with maximum efficiency and precision, even large ones, made of stainless steel, carbon steel, aluminum and special alloys. These automatic systems represent a technologically advanced solution for the assembly and welding of industrial tanks, boilers, tanks and pressure vessels, ensuring constant results, high productivity and reduced cycle times.
At the heart of the process is the four-sector hydraulic expansion system, made of alloy material and subjected to heat treatment to ensure wear resistance, high heat removal capacity and durability over time. The interchangeable sectors allow the system to be adapted to different diameters, ensuring maximum versatility and precision even in the presence of variable production batches.
Among the main technical features:
The system is designed to offer maximum operational flexibility, adapting to a wide range of configurations. The modular architecture allows integration with automated production lines and assisted loading/unloading systems, as well as the possibility of inserting multiple torches or automatic spot welding systems to further improve production efficiency.
ESP systems can be configured with double or single expanders, fixed or mobile, depending on production needs. The high repeatability of the process and the accurate control of pressure and position make these systems ideal for high value-added productions where constant welding quality and traceability of parameters are required.
One of the most advanced configurations of the series includes wheeled versions on rails, equipped with a double system of hydraulic expanders and a mobile beam with an overhead expander, able to automatically adapt to the different tank formats. This solution allows precision hydraulic clamping, which is essential to ensure optimal coupling between the bottom and the ferrule and a uniform and defect-free welding result.
Thanks to their mechanical robustness, clamping precision and integration with digital systems, the ESP series systems are positioned as one of the best solutions for the automation of circumferential welding of primers on ferrule, also from an Industry 4.0 perspective.
