Why Relying on a Single Level Sensor in Storage Tanks Is a Critical Risk (And What to Do Instead)
The Illusion of Simplicity A single-level sensor seems like the obvious, cost-effective solution—especially when tanks appear stable and operations run smoothly. But in industrial storage, apparent simplicity masks systemic vulnerability. One sensor failure doesn’t just mean missing data—it can trigger overfills, under-draws, safety incidents, environmental releases, or unplanned shutdowns. 3 Hard Truths Behind Single-Sensor Reliance 1. No Redundancy = No …Read more -
Why Do Control Valves in PTA Units Keep Jamming? We’ve Identified These 4 Real Causes
Why Is the PTA Environment So Demanding? The process medium in a PTA oxidation unit is an acetic acid solution carrying terephthalic acid (TA) slurry. Typical conditions: acetic acid concentration 85–98%, operating temperature 180–200°C, pressure approximately 15–18 bar. This combination creates what we call a “four-way attack” on any control valve: Concentrated acetic acid corrodes standard stainless steels continuously. TA …Read more -
Valve Technology: Professional Terminology Reference Guide
Part I — Performance Terminology 1. Strength Performance The strength performance of a valve refers to its capacity to withstand the pressure exerted by the working medium. As pressure-bearing mechanical components, valves must possess sufficient structural strength and rigidity to ensure long-term, reliable operation without cracking or permanent deformation. 2. Sealing Performance Sealing performance refers to a valve’s ability to …Read more -
