Stainless steels are common materials for process equipment and components in the chemical process industries in large part because of their corrosion resistance. This one-page reference reviews the properties of stainless steels with regard to corrosion resistance. Passive layer Stainless…
Safety is often underestimated when planning, operating and maintaining process-measuring equipment. Sensors with SIL certification, alone, do not make the process safe. It is important to avoid systematic errors during planning, installation and operation The correct installation of a temperature…
The S-4 Series of screw compressors now includes options for the 45- to 75-kW performance range (photo). All models are characterized by quiet, reliable operation and have high efficiency. The compressors generate high free-air delivery at low specific-power consumption. The…
This company’s 1209 solid-front stainless-steel pressure gage (photo) is now available with the new XRA option, which allows the gage to accommodate up to 400% overpressure without damaging the gage. In applications where pressure spikes, surges and waterhammer are a…
The MC-COS multi-control valve (photo) is a fully integrated device consisting of this company’s COS pressure-reducing valve, a separator, steam trap and a motorized actuator. It is designed for steam conditioning, as well as to control either the steam pressure…
Thoughtful design can help reduce safety risks at process plant sites by proactively eliminating possible hazards and modifying personnel behaviors Safety is an important value in any organization, but is particularly important in the chemical process industries (CPI) when the…
Process equipment is usually connected by pipelines through which, if an explosion occurs, fire and pressure can spread very rapidly. Propagating explosions pose increased risks of secondary explosions. The intensity of the explosion in connected vessels is increased by pressure…
This company’s SLA Series mass-flow controllers (MFCs; photo) and meters now have new global certifications, including those covering the cure dates and shelf life of the elastomers used in the assembly and the surface roughness of the flow path, as…
With proper design, installation, monitoring and maintenance, chemical plant operators can increase the lifecycle of fluid systems — and the bottom line Replacing a fluid system component costs more than just the price of the part itself. It also includes…
This company’s new digital pressure-temperature sensor (DPTS; photo) is designed to measure subcooling for HVAC-refrigeration applications. The DPTS is a self-contained device that measures pressure and temperature and calculates subcooling based on refrigerant type. It is compatible with safety-group A1,…
