Rupture Disk

A Rupture Disk is a device designed to function by the bursting of a pressure-retaining disk. This assembly consists of a thin, circular membrane usually made of metal, plastic, or graphite that is firmly clamped in a disk holder. When the process reaches the bursting pressure of the disk, the disk ruptures and releases the pressure. Rupture disks can be installed alone or in combination with other types of devices. Once blown, rupture disks do not reseat; thus, the entire contents of the upstream process equipment will be vented. The burst tolerances of rupture disks are typically about ±5% for set pressures > 40 psig. (Source: www.wermac.org/)

OPEC-Russia deal faces a new danger: Too much winning (18 January 2018): By GRANT SMITH - LONDON (Bloomberg) -- When OPEC and Russia meet this weekend to review their strategy for clearing a global oil glut, they’ll face an unusual problem: it could be working just a bit too well. As their output cuts, coupled with robust global demand, tighten the market, crude prices have soared to a three-year high near $70/bbl. That’s prompted warnings -- from Iran’s oil minister to Goldman Sachs Group and even OPEC’s own analysts -- of a fresh surge in U.S. production, wrecking all of the group’s hard work.
