Slam-Shut Technology for Ultra-Low-Pressure Protection
Natural gas is an abundant fuel used for both industrial and residential energy and is one of the few energy sources delivered directly into our homes. Because it’s also a flammable, potentially explosive fluid, natural gas utilities and distribution companies are required to prioritize safety and devote focus to their protection systems to prevent over-pressurization accidents, even for systems operating at extremely low-pressure levels (< 1 psi).
Cleaning Polish System After Russian Dirty Oil to Take at Least Six Months

This includes intake and discharge pressures, intake and motor temp..
Looking to Lessen Fluctuating Flow Problems in Measurement
Good measurement practices suggest flow measurements should occur without instabilities or pulsations in the flow. Even minor inaccuracies in the measurement of high value products can lead to significant financial exposure over extended periods of time.
Using Computational Fluid Dynamics When Equipment Fails
The importance of accurate measurement cannot be under-estimated. In 2012, the oil price was above $100 per barrel, but only a year later, as oil prices began to decline, the average price of a barrel of crude oil was $91, dropping to $42 by 2015.

Michigan Panel Approval of Line 5 Deal Ruled Legal by Judge
A Michigan panel's approval of an oil pipeline tunnel beneath the Great Lakes will remain intact even though a state law set unconstitutionally long terms for authority members, a judge ruled.
Unwanted Night Moves
Whenever the subject of internal corrosion in pipelines comes up, it rekindles some unpleasant memories from my extensive time as a pipeline company spokesperson. Being part of an emergency response team for over 12 years was rewarding in many ways, but there was always an uneasy feeling when the phone would ring in the middle of the night.
Damage Tolerance Testing of Small-Diameter Pipelines
Internal and external corrosion, as well as third-party damage such as dents and gouges, are the main causes of pipeline failures worldwide. When such damage is detected by direct inspection, or in-line inspection methods, a decision to replace, repair, or accept and monitor must be made.
San Francisco Gas Explosion Shoots Fire that Burns Buildings
A gas explosion in a San Francisco neighborhood shot flames into the air for hours Wednesday and burned five buildings, sending panicked residents and workers fleeing into the streets. It took utility crews more than two hours to put out the fire after private construction workers cut a natural gas line, igniting the towering flames.
