Rupture disks launched for extrusion applications

A new line of rupture disks has been introduced by analytical instrumentation and sensing technologies provider Dynisco. The rupture disks, also known as ‘burst plugs’ are designed to provide emergency relief of excess pressure build-up in a system by instantaneously rupturing at a specific predetermined pressure range.

The disks are available for burst pressures from 1,500 to 15,000 psi, have an accuracy of ±5% and can withstand melt temperatures up to 399°C (750°F). They are intended for use in extrusion applications and can be used for primary relief in applications where pressure build-up can occur so quickly that the response time of a relief valve is inadequate.

“These products provide low cost insurance against the safety hazards and damage of a potentially catastrophic pressure burst,” comments Matt Carrara, Dynisco vice president of sales and marketing. “We have seen great demand for these products, so we’ve expanded our product line to cover a wider range of pressures, and to work with a wide variety of process connections.”
