Fittings 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 …
Bourdon tube gauges are commonly used for measuring pressure, but this doesn’t mean that a bourdon tube gauge is the best pressure measurement solution for all semiconductor applications. As highlighted in a respected 2018 trade magazine article, a mini …
For a leader in industrial flow equipment and services, one specific application was causing significant difficulties for their end user. The harsh environment – high-temperature chlorinated gas for fiber optic production – was causing half of their pressure …
WIKA USA’s new Dual Switch Gauge offers customers reliable information and exceptional versatility for pressure monitoring in semiconductor, high purity (HP), and ultra-high purity (UHP) applications. A case study shows how one customer was able to increase …
Replacing standard alloy fittings on a pressure gauge with gall resistant fittings is a minor change, but doing so eliminates the major issues associated with standard fittings. Fittings in a gall resistant material ensure a leak-tight seal, prevent particulate …
