Introduction to Differential Pressure Measurement
Hardy Orzikowski | Know-how, PressureBy measuring differential pressure, users are able to easily and accurately monitor filter conditions, liquid levels in closed tanks, liquid flow rates inside a pipe, and even the output torque of hydraulic motors. There are three methods of measuring pressure. The …
Frequently Asked Questions about Gall-Resistant Fittings
Patrick McGrath | Know-how, PressureFittings that flake silver are a major concern in ultra-high purity (UHP) processes. That’s why WIKA has developed gall-resistant nuts made of UNS S21800 stainless steel, a chromium–iron alloy with inherent lubricity and self-mating characteristics to reduce the …
During Lower Throughputs, Monitor the Acid Dew Point Temperature in Fired Heaters to Prevent Corrosion
Robert Torgerson | Know-how, TemperatureLow-level flue gas recovery allows refineries to improve their heaters’ efficiency. However, this process could lead to the condensation of flue gases, and these acidic droplets can corrode equipment. For optimal safety and efficiency, refineries must monitor …
8 Common Reasons For Pressure Gauge Failure
Hardy Orzikowski | Know-how, PressurePressure gauge failure can be attributed to one or more of these eight reasons: mechanical vibration, pulsation, extreme temperature, pressure spikes, overpressure, corrosion, clogging, and mishandling/abuse. Pressure gauges are an integral part of an …
