Larger valves (200 mm and above, with flowrates in excess of 200 m3/h) tend to be fitted with pneumatic actuators. However, the air-output capacity required to achieve fast positioning in larger actuators is simply too high for normal positioners and…
Premature wear of cardan shaft joints is one of the most common causes of machine downtimes. But cardan shaft misalignment is no longer a fatality. With patented brackets and new measurement methods, this company says it has reinvented cardan shaft…
This 110-gallon heavy-duty industrial vacuum (photo) is designed to move material with little wear to the equipment. Engineered to filter contaminants to high-efficiency particulate air (HEPA) requirements, the vacuum is fitted with two filters: a pre-filter to stop larger particles…
This company has simplified transitions to its modular pipework system by introducing adapter flanges, which are available in square or round form. The new adapters are welded onto the machine outlet or inlet ports. Matching counter flanges from the company’s…
The WMP (welded muffled plug) rupture-disc assembly is a single-use unit that is threaded into a pressure system. Designed to relieve the pressure of the process media in an overpressure condition, the unit protects equipment, personnel and the environment from…
Cost estimation is a critical dimension of project planning in asset-heavy industries such as the chemical process industries (CPI). Construction cost indices are useful tools in cost estimation and are used to compare plant construction costs from one time period…
This company has developed a new IO-Link master for its Simatic S7-1200 controller, based on the current IO-Link specification V1.1. The IO-Link master connects field devices to the controller via IO-Link. The field device parameters are automatically backed up in…
Sour-water strippers (SWSs) are common in petroleum refineries, as well as gas-processing and gasification plants, and are used to remove ammonia, hydrogen sulfide and carbon dioxide from contaminated process waters. The design of these units is typically done using the…
Pressure-relief solutions are commonly used in the chemical process industries (CPI) to ensure safe working environments for personnel and to protect equipment and assets. Relief valves (RV) and rupture discs (RD) are the most commonly used pressure-safety devices and are…
Ensuring the security of industrial control systems (ICS) can be a daunting and complex task, requiring expertise and experience in several areas from a variety of contributors. The rapid pace of improvements to both technology and practice adds to the…
