How To Calculate Boiler Tube Thickness
A manufacturer offers a disk design having a standard MDR of +6% to -3% for set pressures greater than 271 psig. A customer orders a disk with a specified burst pressure of 300 psig and standard MDR. When the disk lot is manufactured, the two test burst pressures are 302 and 306 psig, resulting in an average burst pressure of 304 psig.
