Rupture disc price list
Why a fixed price list does not work for rupture discs, and how to get a reliable price indication for your own specification instead.
There is no meaningful rupture disc price list, because every disc is built for a specific burst pressure, material, size and design, often with a holder, documents and burst detection. Instead, Dutch Valve Vision gives a price indication or a no-obligation quotation based on your specification. Send the medium, pressures, temperatures, connection and quantity, or the tag data of the disc you replace.
Looking for a rupture disc price list?
Many buyers type rupture disc price list into a search engine hoping to find a neat PDF with part numbers and prices. We understand why. A price list is quick, it helps with a budget, and it lets you compare suppliers without picking up the phone. For some standard valve designs, lists like that exist and work reasonably well. For rupture discs they rarely do, and at Dutch Valve Vision we have deliberately chosen not to publish one.
That is not secrecy. It follows from the nature of the product. A rupture disc is a safety device built for one set of conditions: one medium, one burst pressure at one temperature, one size and one way of mounting. Change any of those and you have a different disc. A printed rupture disc price list would either run to an unmanageable number of lines that nobody can navigate, or it would show a handful of standard items that almost never match what a plant actually needs.
So what do we do instead? As the exclusive agent of STRIKO Verfahrenstechnik GmbH for the Netherlands, Belgium and Luxembourg, we give a price indication or a no-obligation quotation based on your specification. This page explains why that works better than a list, which variables make up the figure, and what to send us so that the answer comes back quickly.
What a rupture disc price list would have to contain
Try building a rupture disc price list yourself and the problem becomes obvious within minutes. Start with the design. The STRIKO programme includes flat metal discs, forward acting metal discs for high pressure, reverse acting metal discs for durability, aseptic metal discs for pharma and food, extruder discs, discs for tank containers and burst plugs. Add domed discs with an X or C scored dome, vacuum suitable and double discs, and graphite discs from DN25 to DN400.
Now multiply by material. The standard metal disc is 316 stainless steel, with Hastelloy and titanium as options, and graphite comes with an optional TFE coating. Multiply again by diameter, and then by burst pressure, which is not a size class but a specific value chosen for your system, with a tolerance and a temperature attached to it.
Then the extras. Will the disc sit directly between DIN or ANSI flanges, or in a forward acting, reverse buckling or vacuum support holder? Which holder material, from carbon steel through 316/316L stainless steel and duplex to super duplex, Inconel or Hastelloy? Which documents are required: material certificates to EN 10204 3.1, pressure calculations, inspection reports, a PED dossier? Is burst detection needed, and does it have to be suitable for an ATEX zone?
By the time every combination is covered, the list is useless as a list. And the one line that seems to match your process still lacks the most important information of all, which is whether it is the right disc for that position in the first place.
Why choosing from a list can go wrong
Imagine a maintenance planner with a list in one hand and a disc to replace in the other. The old disc is marked with a burst pressure that is not on the list, so the planner picks the nearest standard value. The temperature at which the old disc was specified is not mentioned anywhere, so it is ignored. The list does not say whether the old disc was forward or reverse acting, so the lowest line is chosen. On paper the purchase is complete. In reality the new disc may open too early, fatigue faster under pressure cycling or, worse, open too late.
Each of those shortcuts touches something that matters. Every disc is designed for an exact burst pressure matched to the safe working pressure of the system. The effective burst pressure can fall at higher temperatures, depending on material and design. The operating ratio, the relation between maximum operating pressure and burst pressure, affects service life and reliability. A price list flattens all of that into a single column.
This is why a rupture disc price list, even if it existed, would push buyers toward the wrong question. The useful question is not what a disc costs, but what the right disc for this position costs. Only a specification can answer that, and only someone who reads the specification can give you a figure you can trust.
Unsure about the right choice?
Share your process data with our specialists. We check the numbers with you and give reasoned advice.
What we offer instead of a rupture disc price list
Instead of a list, we work from your specification. You send us the process data, we select the disc type, material and holder with you, and we give you a price for exactly that combination. Depending on where you are in the project, that can be a price indication or a no-obligation quotation.
A price indication is useful early on. An engineer drawing up a P&ID or a project team preparing a budget often needs a realistic figure before every detail is fixed. Based on the data available at that point, we indicate which STRIKO solution fits and what to budget for it. A firm quotation follows once the specification is complete, covering the exact disc, holder, documents and options.
For replacements the route is even shorter. If you have the existing tag data and specification, that is often enough for us to start. We do check whether the process conditions have changed since the original selection, because a modified process may need a different disc, and then we quote the replacement. Failing to reassess after a process change is one of the classic mistakes with pressure relief devices, and a quotation is a good moment to catch it.
Behind every indication or quotation sits the same selection work. We look at the medium and its composition, the operating pressure including peaks, the required burst pressure, and the temperature in normal operation and in the relief scenario. We consider whether a holder is needed, whether vacuum can occur and whether burst detection adds value. That is the part a price list can never deliver.
What a good quotation states that a list never could
A figure without a specification is just a number. A good quotation therefore makes the choices behind the figure visible, and that is what you should expect from us and from any other supplier. The disc type is named, with the reason it suits your process, for example reverse acting because the vessel sees frequent pressure cycling, or graphite because the medium would attack stainless steel. The material is stated, along with the burst pressure, the tolerance and the temperature at which that burst pressure applies. If a holder is part of the offer, its type and material are listed, and if we advise direct flange mounting instead, we say so.
The documentation is spelled out as well: material certificates to EN 10204 3.1, pressure calculations, inspection reports, traceability or a PED dossier where your project requires one. Options such as burst detection, vacuum support or spare discs appear as separate items, so you can see what each adds and decide for yourself. Where an assumption had to be made because a value was missing, the quotation should mention it, so it can be checked before the order is placed.
A quotation built like this does something a list cannot. It lets your process engineer, your safety department and your buyer each check the part that concerns them. The engineer confirms the design, the safety specialist confirms the burst pressure and the documentation, and the buyer compares like with like. Nobody has to guess what a line in a table actually includes.
Building your own reference instead of a rupture disc price list
For plants with many relief positions, there is a practical middle way between no list at all and a generic catalogue. It is a list of your own. Many sites keep a register of every rupture disc position with its tag number, specification, disc type, holder and the date of the last replacement. Add the most recent quotation for each specification, and you have an internal reference that is far more useful than any published rupture disc price list, because every line on it belongs to a real position in your plant.
That register helps in several ways. Positions with identical specifications become visible, so replacements can be grouped and ordered together. Budgets for the next turnaround can be drawn up from actual quotations instead of rough estimates. And when a disc opens unexpectedly, the specification for the replacement is ready in seconds, which shortens the time until the process can restart.
A register is a starting point, not a permanent answer. Process conditions change, and material and production costs move over time, so a figure from an earlier quotation should always be confirmed before a new order. What the register does guarantee is that the conversation starts with a complete specification, and that is the quickest way to a reliable figure. If you do not have such a register yet, the tag data on your existing discs and holders are the natural place to start building one.
Comparing quotations without a rupture disc price list
Without a rupture disc price list to hold offers against, how do you compare suppliers? Compare specifications first and figures second. Two quotations are only comparable if they describe the same product.
Check that both quotes are based on the same burst pressure, the same tolerance and the same temperature. Check whether a holder is included and, if so, which type and material. Check the documentation, because one supplier may include material certificates to EN 10204 3.1, pressure calculations and traceability while another does not. Check whether burst detection is part of the offer. And check the design itself, because a flat disc and a reverse acting disc for the same position are simply not the same thing.
A quotation that looks lower often turns out to cover less. That is not necessarily a problem, as long as you know it. The point of comparing is to make the differences visible before the order, not after installation.
Price versus total cost of ownership
The purchase price of a rupture disc is only one part of what it costs a plant. A disc that opens too early stops production. A disc that fatigues under cycling has to be replaced more often. A holder that does not clamp reproducibly can cause leakage or a wrong burst pressure. Each of those events can cost more in lost production and extra work than the difference between two quotations.
That is why we look at total cost of ownership. A well-designed holder, for example, lowers total cost through less unplanned downtime, a longer service life, predictable behaviour under overpressure and lower maintenance costs. It is built for long-term reuse, so after an event only the disc needs replacing. Keeping spare discs for critical positions shortens every restart. Cheap design often leads to expensive consequences, and a rupture disc price list tends to hide exactly that trade-off behind a single figure.
What to send for a fast quote
The sooner we have complete data, the sooner you have a reliable figure. For a new position, send us the medium and its composition, the operating pressure including peaks, the required burst pressure, and the temperature in normal operation and in the relief scenario. Add the connection with flange standard and nominal diameter, the available installation space and any back pressure. Tell us whether the system can see vacuum, how many positions share this specification, which documents your project requires and if burst detection is wanted.
For a replacement, send the tag data and current specification, and tell us if anything in the process has changed. For a budget estimate in the design phase, send what you have and tell us which values are still open. In each case the principle is the same: the more we know, the fewer questions we need to ask and the more precise the figure becomes.

Frequently asked questions about rupture disc price list
Why is there no rupture disc price list?
A rupture disc is built for one specific set of conditions. Burst pressure, temperature, material, diameter and design all differ from one position to the next. On top of that come the holder, the documentation and options such as burst detection. A list that covered every combination would be far too large to use. A short list of standard items would rarely match what a plant actually needs. Choosing the nearest item from a list can lead to a disc that opens too early or too late. We therefore price each disc on the basis of your specification. That gives you a figure that belongs to the right disc rather than to a similar one.
Can I get a price indication before my specification is complete?
Yes, and in the design phase that is often exactly what is needed. Send us the data you have and tell us which values are still open. Based on that, we indicate which STRIKO solution fits and what to budget for it. An indication is not a firm quotation, because open values can still change the choice. Once the specification is complete, we turn the indication into a no-obligation quotation. That quotation covers the exact disc, holder, documents and options. This two-step approach helps project teams budget early without committing too soon. It also brings design questions to the surface before they become costly later in the project.
How do I compare two rupture disc quotations fairly?
Compare the specifications before you compare the figures. Check that both quotations use the same burst pressure, tolerance and temperature. Check the disc type, because a flat disc and a reverse acting disc are different products. Look at whether a holder is included and which type and material it is. Compare the documentation, such as material certificates to EN 10204 3.1 and traceability. See whether burst detection is part of the offer or not. A quotation that looks lower often simply covers less. Once the scope is the same, the comparison becomes fair.
Is a replacement disc quoted differently from a new one?
The selection logic is the same, but the starting point is quicker. For a replacement, the existing tag data and specification are often enough to begin. We do check whether the process has changed since the disc was originally selected. A new medium, a higher temperature or a different operating pressure can require another design. Not reassessing after a process change is a common mistake with pressure relief devices. If nothing has changed, we quote the matching replacement disc. An existing holder in good condition can usually be reused, because holders are designed for long-term use. Adding spare discs for critical positions to the same order is a sensible step.
Why does total cost matter more than the purchase price?
The purchase price is only the first part of what a rupture disc costs a plant. A disc that opens too early interrupts production. A disc that fatigues under pressure cycling needs replacing more often. A holder that clamps poorly can cause leakage or a wrong burst pressure. Each of these events can cost more than the difference between two quotations. A well-designed holder reduces unplanned downtime and maintenance costs over the years. It also gives predictable behaviour under overpressure and a longer service life. That is why we look at the whole life of the installation when we advise.
What if I do not know all the process data?
That happens more often than you might think. Send what you have and tell us which values are missing. Sometimes a value can be derived from the existing tag data or the current specification. In other cases the process engineer or the P&ID provides the answer. We ask targeted questions rather than guess, because guessing is not acceptable for a safety device. The temperature in the relief scenario is a value that is often overlooked. Operating pressure peaks are another, especially in processes with frequent cycling. Once the gaps are closed, we can move from an indication to a firm quotation.
Which connections and standards can you quote for?
We supply according to both DIN and ANSI/ASME. Metal discs can be clamped directly between flanges or mounted in a dedicated holder. Graphite discs from DN25 to DN400 fit directly between ANSI or DIN flanges or in a holder. Our holders are designed in line with ASME Section VIII, EN ISO 4126 and PED 2014/68/EU. Where applicable, ATEX requirements are taken into account. Metal rupture discs fall under the PED, ISO 4126, EN 14491 for explosion safety and CE marking. Tell us the flange standard, rating and nominal diameter with your enquiry. That lets us quote the right disc and holder the first time.
Who prepares the quotation, Dutch Valve Vision or STRIKO?
For customers in the Netherlands, Belgium and Luxembourg, we do. Dutch Valve Vision is the exclusive agent of STRIKO Verfahrenstechnik GmbH for these three countries. We handle the selection, the price indication and the quotation. STRIKO manufactures, tests and calibrates the discs. Its philosophy of testing, evaluating and recalibrating has guided its rupture disc work since 1974. Our office in Monster is your single point of contact from enquiry to delivery. We are reachable Monday to Friday from 09:00 to 17:00 on +31 (0)70-2210560. Enquiries can also go to sales@dutchvalvevision.com.
