Invention Reference Number
Researchers have developed a compact, additively manufactured pressure-limiting structure (PLS) designed for critical environments, such as irradiation capsules in nuclear research reactors. This innovative design enhances safety by providing a controlled pressure release mechanism that does not negatively impact the design function of the original component but improves safety performance by preventing catastrophic failures. The technology has a broad range of applications in sectors requiring precise pressure regulation, including aerospace, automotive, petrochemical, and defense industries.
Description
The PLS is fabricated using laser powder bed fusion additive manufacturing, allowing for rapid, customizable production. It incorporates a rupture wall designed to relieve pressure at a predetermined threshold, ensuring safe operation for many challenging situations. The structure integrates physical barriers to contain debris and minimize energy release upon rupture. The printed components are tested to ensure consistency and reliability, with a narrow distribution of rupture pressures. This novel pressure relief technology offers a cost-effective and scalable solution for conditions where precise pressure control is critical.
