Over the years, many of our customers who once experienced the stresses of rupture disk problems would come to us with one important question: When should a Rupture Pin valve be considered as a replacement for a rupture disc?

After answering the same question time and again, we decided it was best to develop the following checklist to help you decide when to switch. Now you can judge for yourself whether your plant, process or program may benefit from our advanced valve technology by answering the questions below.

A Yes response in ANY area indicates Rupture Pin valves can provide improved efficiency, safety in your application and decrease downtime involved with replacing failed disks.

Areas You May Face Rupture Disc Problems

Yes ..No
---------------------------------------------------------------------------------------------------------------------------------------------
I follow the rupture disc manufacturer's recommendation and replace discs annually.
Yes ..No
---------------------------------------------------------------------------------------------------------------------------------------------
I have experienced system pressure surges that cause premature disc failure due to fatigue.
Yes ..No
---------------------------------------------------------------------------------------------------------------------------------------------
System chemicals attacking rupture disc material have caused premature disc failures.
Yes ..No
---------------------------------------------------------------------------------------------------------------------------------------------
I have noted that system temperature variations can cause the rupture disc to fail early or late.
Yes ..No
---------------------------------------------------------------------------------------------------------------------------------------------
Getting replacement discs to my plant has taken more than 24 hours and included
excessive premium costs.
Yes ..No
---------------------------------------------------------------------------------------------------------------------------------------------
My system fluid is toxic or an environmental hazard, so dangerous fugitive emissions are released to the atmosphere and ground water when changing rupture discs.
Yes ..No
---------------------------------------------------------------------------------------------------------------------------------------------
I have experienced costly process downtime during disc changes.
Yes ..No
---------------------------------------------------------------------------------------------------------------------------------------------
Disc changes at my plant require skilled labor. This assures the disc is not installed backwards and that torque ratings and order of tightening are strictly followed.
Yes ..No
---------------------------------------------------------------------------------------------------------------------------------------------
At all rupture disc set points the product of the tolerance chain is excessive.
(manufacturing tolerance X temperature tolerance X standard tolerance)
Yes ..No
---------------------------------------------------------------------------------------------------------------------------------------------
Metal or plastic shards violently discharged from a failed rupture disc have injured nearby personnel.
Yes ..No
---------------------------------------------------------------------------------------------------------------------------------------------
Metal or plastic shards from failed discs have clogged downstream piping and damaged downstream equipment or valves.
Yes ..No
---------------------------------------------------------------------------------------------------------------------------------------------
System back pressure radically changes the set point of the rupture disc.
Yes ..No
---------------------------------------------------------------------------------------------------------------------------------------------
Back pressure surges have caused forward-buckling discs to reverse buckle and fail early.
Yes ..No
---------------------------------------------------------------------------------------------------------------------------------------------
Discs have prematurely buckled on holidays or weekends, causing scheduling and overtime difficulty.
Yes ..No
---------------------------------------------------------------------------------------------------------------------------------------------
The plant storeroom has been closed at the time we needed a replacement disc.
Yes ..No
---------------------------------------------------------------------------------------------------------------------------------------------
We use many discs in our system. We can’t tell which disc has failed... because the Broken Disc
Indicator malfunctions.
Yes ..No
---------------------------------------------------------------------------------------------------------------------------------------------
The rupture disc in our sewage dewatering process failed... and we had to change the disc.
Yes ..No
---------------------------------------------------------------------------------------------------------------------------------------------
The rupture disc in our toxic process failed... and we had to suit up for the job to change the disc.
Yes ..No
---------------------------------------------------------------------------------------------------------------------------------------------
Standard rupture disc tolerances are excessive below 40 psi.
Yes ..No
---------------------------------------------------------------------------------------------------------------------------------------------
The premature failure of a rupture disc caused a fugitive emissions danger to nearby communities that resulted in a lawsuit and an EPA fine.
Yes ..No
---------------------------------------------------------------------------------------------------------------------------------------------
