Tips for Specifying and Buying Rupture Discs (Bursting Discs)

Tips for Specifying and Buying Rupture Discs (Bursting Discs)

By Peter Meek

If you are looking for Rupture Discs (otherwise referred to as Bursting Discs) then here are a few points that you may want to consider when specifying and buying your rupture discs. As discussed in our previous blog on rupture discs, there are a number of possible configurations that you will want to consider. Once you have decided upon your installation configuration, you will need to decide upon the performance parameters of the bursting/rupture disc. The following important factors should be considered when selecting the rupture disc/bursting disc for the required configuration:

Rupture disc (bursting disc) Manufacturer: There are various manufacturers on the market. Each has their own area of specialty. Be sure that your selected rupture disc manufacturer has experience in the application that you are using. Clear communication with your supplier will ensure that they fully understand your needs and can provide the best suited product for your application. By using engineering circle approved rupture disc manufacturers you can be sure that your supplier will have the skills and experience to meet your needs.

Materials: Material selection needs to be considered when selecting the rupture / bursting disc. Materials available for off the shelf applications range from Carbon Steel, Stainless Steel and alloy mixtures. Custom designed rupture discs will be available in a wider range of materials, but of course these will come at a greater cost. Material selection should consider the corrosion and abrasion resistance required.

Tolerance: Manufacturers will often stipulate the allowable tolerance for their products. i.e. the rupture disc could burst at +/- x barg from the actual pressure selected. These tolerances need to be considered in the design of the pressure system which is being protected. Generally the designer will use the greater pressure of the tolerance range as the design pressure.

Reliable life and inspection requirements: Remember that in most installation configurations rupture discs cannot be maintained in service. Therefore they will often have quite stringent reliability requirements. If this is of a concern then you may need to consider another configuration which will allow in service inspection and maintenance of the rupture disc. Maintenance requirements should be made clear to the rupture disc manufacturer at the time of purchase.

Method of Manufacture:   Different manufacturers will have different methods of manufacture which result in varying quality and tolerance ranges. If the tolerance range is acceptable, and you are happy with the materials then the method of manufacture need not be considered in detail. If you are having problems finding the right tolerance for your application then the method of manufacture may need to be considered.

Your Rupture / Bursting Disc Manufacturer should know their product best so be sure to give them as much information as possible to enable them to provide you with an accurate quotation which fits with your needs. Don’t be ashamed to ask your rupture / bursting disc manufacturer questions as they are the experts and you are paying them for their expertise.

Hindsight is a wonderful thing but foresight is better – Welcome to the EngineeringCircle Blog

By: Peter Meek

EngineeringCircle focuses on the buyer/seller relationship in the Global Oil & Gas, Power and Mining industries. Here at EngineeringCircle we aim to optimize the relationship between equipment buyers and equipment suppliers from for the Oil & Gas, Power and Mining Sectors, by creating and maintaining a database of pre-approved equipment suppliers for each sector.   But we are more than just another database or directory. We focus on what matters to the sectors we serve and we audit suppliers to ensure that EngineeringCircle approved suppliers really are good enough to supply the sectors we serve.

“Quality is never an accident; it is always the result of high intention, sincere effort, intelligent direction and skillful execution; it represents the wise choice of many alternatives.” William A Foster.

Here at EngineeringCircle we also believe that quality is never an accident, and we strive to be a stepping stone for our users on the way to achieving the quality that they require.

“Hindsight is a wonderful thing but foresight is better, especially when it comes to saving life, or some pain!” William Blake.

We use both hindsight (industry best practice and lessons learnt) and foresight to ensure that the highest health and safety standards are upheld by our suppliers. We believe that a zero harm environment can be achieved, we expect this same belief from our manufacturers and we encourage our users to strive for this too.

So how do we ensure that our pre-approved suppliers meet the standards expected by the buyers from the various sectors we represent? Our team of professional engineers understand their industries inside and out. We audit all suppliers and manufacturers against the points that matter to each sector. In general all suppliers are audited against the following points.

  • Health, Safety and Environmental
  • Engineering Design and Procurement
  • Quality Assurance and Quality Control
  • Relevant Industry Experience
  • Manufacturing Facility
  • Financial Stability

Once a manufacturer or supplier audit is complete, the company will be given an EngineeringCircle score. Companies that pass the EngineeringCircle audit will be invited to list on our website. Companies that fail the audit, will be allowed to retry once they have rectified the areas we identify as inadequate.

We’ll use this blog space to update engineering and procurement professionals and equipment suppliers and manufacturers as to what is going on in their industries. Most of our content will focus on the Oil & Gas, Power and/or Mining Sectors, but we’ll occasionally stray to areas that we feel are of value to our readers. EngineeringCircle understands the importance of Health and Safety so this is bound to feature prominently in our posts.
