Facts at your Fingertips: Pneumatic Conveying Challenges
Among the key benefits offered by pneumatically conveying bulk solids is the ability to route materials around obstructions in the plant using bends in the pipeline. However, these changes in direction involve a considerable number of particle impacts on the…
Preparing for a Successful Security Audit
Facing a site security audit might seem daunting, but proper preparation will help to meet the goals of enhancing security and reducing risk What are the downsides of failing to pass a security audit or inspection? Is it the fear…
Seal Selection: Ensure Regulator Performance in Low-Temperature Applications
In low-temperature conditions, the use of compatible sealing materials is essential for leak-tight operation and proper functionality of pressure-regulating devices Harsh, frigid conditions are among the most challenging industrial environments (Figure 1) for fluid-handling applications. At these temperatures, it is…
Pump Sealing for Hazardous Chemicals
Pumping hazardous chemicals requires specific shaft-sealing technologies to ensure containment and reliability Hazardous chemicals are defined by the Environmental Protection Agency (EPA; Washington, D.C.; www.epa.gov) as those that are potentially harmful to human health and the environment. Existing as gases…
