Frequently Asked Questions

Pressure Relief

I’ve never specified a rupture disc before and don’t know where to start. What questions do I need to answer to begin?

The basis for selecting a rupture disc begins with an over-pressurization hazard being determined by a process engineer. Details on the process will be needed to properly select a product that works reliably, so often engineers or technicians familiar with the operations specify them. In other cases, it may be necessary to provide a pressure relief device “just in case” on a pressurized piece of equipment. We have created this questionnaire for you to use with your rupture disc specifications. If you require assistance to complete, please contact a Fike representative.

What is meant by the term “manufacturing range”?

Manufacturing range is an ASME/API standards definition  for allowing the “burst pressure” of the rupture disc to vary from the nominal value specified on your order.  This is expressed as a variance in percent (%) from the nominal value, and the actual marked value on the nameplate is determined during the fulfillment of your order.  For simplicity, Zero manufacturing range is suggested. With Zero manufacturing range, if you order a 100 psig rupture disc, the tagplate and paperwork all state 100 psig.

Can a rupture disc be reused?

Once the rupture disc is damaged or burst, it cannot be reused. More information on this topic of replacement period can be found in the service life article.

How do you know the burst pressure of the rupture disc?

Each rupture disc is produced in a “lot”.  Each lot of rupture discs has samples destructively burst tested to directly measure the burst pressure.  This sample plan is based on the standards/codes as a minimum criteria.

I have heard a rupture disc can be installed with a relief valve, will any rupture disc from Fike work?

There are many rupture discs that work satisfactorily with relief valves, but several considerations need to take place. Technical Bulletin 8105 provides a list of the typical considerations prior to making a purchase decision.  We also recommend reading Chemical Engineering’s Getting the Most Out of Your Rupture Disc to improve your experience with Fike Rupture Discs.

Where can I find the relief area’s for each of the rupture discs you provide?

Technical Bulletin 8104 should answer your question.

Can I use any rupture disc in my current holder?

No. Each rupture disc model is explicitly intended to perform as expected in a holder design of the same manufacturer.  Some rupture discs “may fit” into a like holder of another manufacturer, but performance cannot be assured. Consult the manufacturer if there is any doubt on the proper holder for your rupture disc make and model.

I need to reorder the rupture disc and don’t have the box, what information do you need?

The tagplate contains a lot number and can be provided to Fike for a duplication of the specifications.  Please provide this upon request for quote.

How do I find the installation instructions for my rupture disc?

Instructions are included with each shipment.  If they are not found, please contact Fike with the lot number off the tagplate to obtain a PDF copy emailed to you.

What’s the difference between a laser ablated, scored rupture disc?

Take a look at our Overpressure Protection page to learn more about the features and benefits of laser ablated and scored rupture discs.

Explosion Protection

How do I know if my dust is combustible?

We are here to help you through a simple process that will evaluate your facilities types of dusts, their potential combustibility, and products that you can use to mitigate risks associated with the combustion potential. Reach out to a Fike representative to schedule a visit from an expert to start the process. And explore our educational materials, such as this Explosion Solution Selection Guide, and the Testing Table in the meantime.

The dust collector came new from a reputable dust collector OEM with an explosion vent, is that sufficient to satisfy NFPA?

Maybe. The dust collector vent may have been sized for a given set of combustible dust conditions, that must be reviewed to be true as part of your ongoing responsibilities to satisfy the local regulations such as indicated in NFPA.  As well, the dust collector may require flameless venting if it has been placed indoors, or a vent discharge duct. Additionally, the inlet line and return airlines need to be isolated. A full review needs to occur to ensure the hazard conditions are satisfied.

The explosion system purchased from Fike will not be installed in the same country where it is purchased, is this okay?

Explosion protection regulations change from country to country relative to NFPA, ATEX, pressurized equipment requirements, electrical wiring/component requirements, even the equations used by the standards to determine the sizing and selection of hardware.  Furthermore, explosion protection equipment needs to be maintained by factory trained technicians, and consideration should be made under the consultation of the manufacturer that all these items can be satisfied prior to making a purchase decision.

Do Fike explosion solutions work with fire protection?

It is possible to have both types of systems on a vessel. Your Fike contact will help you through these systems.

I have an outdoor requirement; do you offer a solution that will work?

Yes, all Fike explosion protection hardware can be installed both indoors and outdoors. And in the cases of some venting, a weather cover may be used.
