Digitalization to Predict Reliability of Mechanical Valves

Clear understanding of failure mechanisms for electronic components and mechanical parts will help end users design their BPCS related field devices more optimally and accurately.  This will help eliminate initial premature failures and unnecessary plant trips during normal operation. It also will help end users determine what systems are fit for purpose, which will result …

5 Benefits of Using Coatings in the Oil & Gas Industry

There are many factors that contribute to decreased equipment life in the oil and gas industry. These include drilling, moving oil and gas towards factories, relentless interaction with rough seawater and continued contact to harsh weather conditions. Where regular maintenance is not an option, these factors need tough coatings to prolong equipment life. Some coating …

Prevent Faulty Installation of Bolted Flange Connections

Bolted flange connections are a common method of connecting pipes to process components. They allow access for inspection, maintenance and repair, and can be assembled and disassembled relatively quickly. While the bolted flange connection is, on the surface, a relatively simple mechanical component, the consequence of failure can be severe, causing unwanted downtime, revenue loss …

Solutions for Multistage Pump Failures on Low-Viscosity & Low-Specific Gravity Application

The Background Two 11-stage BB5 pumps of 50 kilowatt (kW) rating—running at 60 Hertz (Hz) and 3,575 revolutions per minute (rpm)—were commissioned on a 2 x 100 percent configuration to naphtha (specific gravity of 0.685 and viscosity of 0.4). The pumps were designed to deliver 21.2 cubic meters/hour (m3/hr) at a differential pressure of 35.4 …
