CERTIFLOW Brochure

Continental Disc Corporation is accredited and authorized by the ASME to utilize the Code Symbol Stamp for product built in ac-cordance with the requirements of the ASME Boiler and Pressure Vessel Code, Section VIII, Division 1.The complete line of CERTIFLOW® rupture discs meets all ASME Code requirements, including KR and MNFA values. With the exten-sive line of CERTIFLOW rupture discs, there is one available to meet most applications and operating conditions.Certified KR values represent tested flow resistance values. Relief systems can be designed or evaluated more precisely and safely if certified flow resistance values are used, rather than industry prac-ticed estimates. These estimates may not accurately reflect the flow resistance of the rupture disc. Using the certified flow resistance value, along with proper engineering practices, allows precise, ef-ficient, and safe design of relief systems.1-1112ASME Compliant Rupture DiscsThe ASME Boiler and Pressure Vessel Code, Section VIII, Division 1, specifies that rupture disc devices, like all other pressure relief products, should be tested and certified as to their flow characteristics, and that these certified values should be used in flow and sizing calculations.Rupture disc products manufactured in accordance with all applicable rules of ASME Code Section VIII, Division 1 must carry the Code Symbol Stamp (shown at left) on the tag, as well as the certified flow resistance (KR) and minimum net flow area (MNFA) values. The "NB" stamp acknowledges The National Board of Boiler and Pressure Vessel Inspectors as the organization that certified the flow tests. CERTIFLOW ®“K” values are pressure loss expressed as the number of velocity heads and they are available for nearly all piping system devices and components, including rupture discs.Rupture disc devices should be included in the flow equation in the same manner as all other system components to determine the relieving capacity of the entire relief system. Design engineers are provided with certified KR values:• which enable the designer to meet ASME Code Section VIII, Division 1 for relief system design• which may permit a reduction in pipe size and associated piping costs when utilized during a relief system design• for use when evaluating relief systems where two-phase flow may occur• for use when re-evaluating existing relief systems to comply with design documentation requirements of OSHA CFR 1910.119," Process Safety Management of Highly Hazardous Chemicals."Two Ways to Use a Certified Flow Resistance FactorTo confirm a rupture disc/PRV combination follows the “3% Rule”The system shown might be designed new, or it might be re-evaluated to comply with OSHA CFR 1910.119, which requires that systems be designed with “recognized and generally accepted engineering practices.” In the past, an estimated value for the flow resistance of the rupture disc would be used for calculations.Combining the certified flow resistance value (KR) with the K values of the other piping components, a design engineer can now accurately evaluate this system’s nonrecoverable pressure loss.To specify a rupture disc device to comply with the ASME Code: 1) Select the most appropriate rupture disc model for your application. Use the Rupture Disc Selection Guide (Bulletin #1-1100) or contact your local representative for assistance2) Find the type, holder, media, required options, and estimated size in Table I or II 3) Find the corresponding MNFA in Table III4) Use the KR and MNFA values to confirm the flow characteristics of your relieving system. For assistance with flow of fluids calculation, consult Crane Technical Paper No. 410. There is also a variety of software titles that will automate your flow of fluid calculations. Be certain that your evaluation uses proper engineering practices such as including all piping system components into your flow calculations and multiplying the calculated relieving capacity by a factor of 0.90 or less as specified in ASME Code Section VIII, Division 1.A copy of Continental Disc Corporation's Certificate of Authorization to use the Code Symbol Stamp can be found on our website at www.contdisc.com. There you will also find the most current CERTIFLOW data. Look for the stampTo confirm relief capacity requirements in a sole relief device systemCombining the certified flow resistance (KR) with the K values of other piping components (shown in example A) allows the design engineer to accurately calculate and evaluate a relief system’s flow capacity. Even for simple relieving systems that can be evaluated with the coefficient of discharge method (8 & 5 rule), utilizing the certified flow resistance (KR) along with the associated K values for the other piping components (shown in example B) will allow for the flow capacity to be more accurately evaluated.Example AExample BCERTIFIED VALUESTable I — Continental Disc Corporation Certified Rupture Disc ProductsRupture Disc Type Seat Code Rupture Disc Holder Type Media OptionsSize Range Min.
