Specification of Rupture Disk Burst Pressure - National Board of Boiler …

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.

Water Handbook - Boiler Blowdown Control | SUEZ

There are many mechanical factors that can affect the blowdown control limits, including boiler design, rating, water level, load characteristics, and type of fuel. In some cases, the blowdown control limits for a particular system may be determined by operating experience, equipment inspections, or steam purity testing rather than ASME or ABMA water quality criteria.

Water Handbook - Boiler System Failures | SUEZ

Straight tube, shell-and-tube waste heat boilers frequently develop tube and tube sheet failures due to the imposition of unequal stresses. A primary cause of this is the uneven distribution of hot gases across the face of the tube sheet. The tubes involved tend to come loose, creating leakage problems.
