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 …

Selecting the Right Butterfly Valve for Your Application

Fluid handling presents many of the challenges faced by industries that deal with the transference of media. It is not uncommon to find different fluid states (gas, liquid, slurry or fluidized solid) within a piping system that require a way to control the flow of the fluid. Strategically placed valves are a powerful means to …

Sealing Vertical Turbine Pumps & Supporting Their Shafts

Vertical turbine pumps (VTPs) are used in numerous industries, including power generation, pulp and paper, mining, and water and wastewater. The shafts on these pumps extend many feet under the ground, sometimes as deep as 2,000 feet.   Because of this and the often harsh and remote conditions in which they operate, these pumps must …

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 …

Bringing Safe & Sustainable Water Solutions to the World

Everyone depends on clean water. In most developed countries, we expect water to run before we fill our empty glass, clean our dirty clothes or flush the toilet.  Safe water and sanitation are basic needs. Yet, many people—2.1 billion of them—do not have access.        In 2001, Water Mission, an engineering nonprofit, set …

Benefits of Vacuum Pump Systems

Vacuum pump systems are used for dewatering saturated materials, filtering liquid from slurries, evaporative drying or pneumatic conveying. These types of vacuum systems are used in paper making, food processing, steam turbine power and chemical manufacturing. Image 1 shows the lettered components of a vacuum system referenced in this article. All units in this article …

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 …
