- Company details
DonadonSDD is an Italian manufacturer of rupture discs and related pressure safety devices for industrial applications. Based in Corbetta, near Milan, the company designs and manufactures custom-engineered rupture discs, rupture disc holders, rupture burst indicators (BDI) used to protect equipment and processes from overpressure and, in certain configurations, vacuum conditions. DonadonSDD serves customers in more than 100 countries and ships worldwide.
Since 2025, DonadonSDD has been part of Baker Hughes, following Baker Hughes’ acquisition of Continental Disc Corporation (CDC) in August 2025. In the transaction announcements surrounding DonadonSDD’s acquisition, Corbetta was identified as the European manufacturing center of excellence for the business, reinforcing the site’s role as a strategic production and engineering hub serving global industrial markets.
DonadonSDD is particularly associated with rupture disc technology for demanding applications across sectors such as chemical processing, pharmaceuticals, food and beverage, refining, power, aerospace and energy. A distinguishing element of its portfolio is the NS NanoScored range, a proprietary manufacturing laser technology used for fully metallic rupture discs. The NS NanoScored platform is designed to deliver high reproducibility, tight tolerances, strong performance at low burst pressures, resistance to fragmentation, and suitability for demanding operating conditions, including cycling service and, in some models, absolute vacuum.
The company’s product and quality profile is aligned with regulated industrial environments. DonadonSDD complies with ISO 9001 and EN 9100 requirements, while its products are available with certifications and approvals including PED, ATEX, ASME UD, 3-A and EAC, depending on model and application. This combination of engineered customization, certified manufacturing, and global industrial reach positions DonadonSDD as a specialized rupture disc manufacturer within the broader Baker Hughes pressure management portfolio.

DonadonSDD is an Italian manufacturer of rupture discs—also known as burst discs, bursting discs, pressure safety discs, or burst diaphragms—together with holders, rupture indicators, and explosion vent panels for industrial protection. The company designs custom-made safety devices to protect plants, equipment, and pressurized systems from overpressure and, in some cases, vacuum conditions. DonadonSDD combines Italian manufacturing, advanced engineering, and a patented laser-based process to deliver precise, reliable, high-performance rupture disc solutions worldwide. Each product is tailored to the application and validated through rigorous testing, including digital gauge tests and oven tests up to 600°C, which customers can witness on site or via livestream. DonadonSDD holds ISO 9001 and 9100 certifications, with products approved under ASME UD, PED, ATEX, UKCA, EAC, MOCA, GPM, and 3-A.
A rupture disc—also called a burst disc, bursting disc, pressure safety disc, or burst diaphragm—is a non-reclosing pressure relief device used to protect pressurized equipment from overpressure and, in some applications, vacuum conditions. It consists of a calibrated membrane designed to open at a predetermined pressure, helping protect vessels, pipelines, reactors, heat exchangers, and other process equipment. Unlike a valve, a rupture disc is a one-time-use safety component: once it bursts, it must be replaced. Rupture discs are widely used in industries such as chemical, pharmaceutical, food, oil and gas, energy, and sanitary processing. In this field, DonadonSDD is an Italian manufacturer specialized in custom-made rupture discs, holders, and rupture indicators for industrial pressure protection.
DonadonSDD rupture disc installation video for industrial pressure safety applications. This video explains how to correctly install a rupture disc—also known as a burst disc, bursting disc, or pressure safety disc—into its holder to protect pressurized equipment from overpressure and, where required, vacuum conditions. It is designed for engineers, maintenance teams, EPC contractors, OEMs, and plant operators seeking practical guidance on rupture disc handling, assembly, and positioning within pressure protection systems.

Rupture disc NS NANOSCORED
NS NanoScored rupture discs are DonadonSDD’s advanced fully metallic rupture discs for industrial pressure protection. A rupture disc—also called a burst disc, bursting disc, pressure safety disc, or burst diaphragm—is a non-reclosing pressure relief device designed to protect pressure vessels, process equipment, pipelines, tanks, reactors, and other pressurized systems from overpressure and, in some applications, from damaging vacuum conditions.
Unlike re-closing relief devices, a rupture disc is a one-time-use safety component. Its metallic membrane is engineered to open or burst at a predetermined differential pressure, either under positive pressure or vacuum, helping protect equipment, processes, and personnel.
The DonadonSDD NS NanoScored series represents an advanced development of the company’s rupture disc technology. DonadonSDD states that it has been awarded an EU patent for the NS NanoScored rupture disc manufacturing method. The NS NanoScored range is designed as a fully metallic rupture disc solution for a wide variety of industrial applications requiring precision, reliability, and process compatibility.
The NS NanoScored portfolio includes both major rupture disc operating principles:
• Forward-acting rupture discs (tension-loaded), such as SCD
• Reverse buckling rupture discs (compression-loaded), such as SCR
• Circumferential-opening reverse buckling designs, including Y90 and KRD
This makes the NS NanoScored family suitable for customers looking for metal rupture discs, high-performance burst discs, forward acting rupture discs, reverse buckling rupture discs, and pressure relief discs for demanding process environments.
Within the broader DonadonSDD product range, NS NanoScored rupture discs are positioned as engineered safety devices for applications where accurate burst pressure, process safety, equipment protection, and reliable pressure relief performance are critical.
