OEMs in virtually every market, from aerospace and automotive to refrigeration and fire protection, rely on rupture disk devices for pressure relief and pressure release of gases and liquids. The challenge of time faces all product designers; how do we get a custom solution in an acceptable timeframe?
“OEMs often require a unique rupture disk in terms of its dimensions, material combinations, or the operating conditions. In many cases, the rupture disk is a last-minute consideration once other design parameters are defined and so they need a custom prototype delivered within relatively tight timelines as part of their product development,” says Geof Brazier, Managing Director, BS&B Safety Systems, Custom Engineered Products Division.
Recognizing the need, BS&B Safety Systems developed a comprehensive support program called the Prototype Introduction Team (PIT) for OEMs that require a ‘white glove’ experience for custom rupture disk device.
The program was developed and patterned after the race car pit crew strategy, where highly trained individuals quickly and seamlessly work together – each with a specific role in the process and with a high degree of anticipation of the customers’ requirements. At BS&B, the PIT team involves experts assembled from sales, engineering, purchasing, manufacturing, and quality control. The PIT team incorporates design engineering throughout and manages all aspects of scheduling to ensure quality, performance, and aesthetic condition with on-time completion and delivery.
According to Brazier, the PIT Program design team’s expertise extends from rupture disks and buckling pin valve technology to explosion protection and prevention devices. The custom engineered products team has decades of machining experience, which now embraces 3-D printing capabilities to reduce the time required for prototype manufacture.
One area of application that benefits from the PIT program is pressure safety management for e-mobility systems. In this case, BS&B manufactures battery pack and cell pressure relief eVents used in the e-mobility industry, each of which must be tailored to each project to ensure design flexibility and required burst pressures.
BS&B typically streamlines the process of battery vent selection by offering an array of technology that can be customized. With this approach, many different design alternatives can be quickly winnowed down to those that work the best for the application. For the rupture disk application interface, choices such as threaded, clamped, bolted, snap-fit, quarter turn, or adhesive bonding can be chosen.
Additional considerations available to the OEM can include novel product marking, inclusion of integral flame arresters or Burst Alert® sensors, as well as cleaning, custom packaging, and certifications. Extensive validation capabilities further support the OEM to achieve project targets on time and on budget.
“Every application is unique, so questions inevitably arise. To ensure the OEM can get answers at any time during prototype creation, we assign a project manager to serve as a single point of contact,” says Brazier, adding that close coordination not only reduces potential technical issues but also supports the customer who may have evolving design factors that impact the pressure relief device and may trigger a running change.
