The new model TFS135 bimetal temperature switch (photo) has been designed for a wide range of applications. It is suitable for switching voltages of up to 250 V a.c. (2.5 A) and has a UL approval (cURus) for the North…
The Gyrolok XP system of tube fittings (photo) is specifically designed to address the challenges of assembling fittings onto a wide range of corrosion-resistant, heavy-wall small-bore tubes. These fittings can grip heavier wall tubes, which is said to increase working…
The UltraPure model (photo) from the Unique Mixproof valve product line is designed to meet the standards of biotechnology and pharmaceutical applications. Valves are packaged to ensure full traceability and are available in high-alloy materials, such as Hastelloy C22 and…
This company now offers protective light curtains for its tumble blenders (photo) to provide automatic safety shutoff whenever an operator crosses a defined security boundary. Due to the nature of the rotating mix chamber, a safety railing is supplied as…
Several methods are available for sizing two-phase pressure-relief valves (PRVs). Here, the API 520 homogeneous direct integration method is compared to a potentially simpler alternative that does not require integration Two-phase pressure-relief valves (PRVs) have been studied by many researchers.…
With the proper knowledge, engineers can work alongside compressor manufacturers to ensure that an optimal air compression system is installed There are various factors to consider when designing a compressed air system that help to improve the reliability and efficiency…
Areas of recent activity for pressure-relief systems include new calculation methods and updates to existing codes and standards. Included here is an overview of recent developments and a look at the results from a recent study of pressure-relief system deficiencies…
Predictive maintenance for rotating machinery is gaining prominence as plant operators embrace analytics and learn how to approach their operating benchmarks Rotating machines, such as motors, compressors, pumps and turbines, are critically important components of plant operations, and must perform…
