Hydrogen Induced Cracking (HIC) Explained for Valves
Learn how hydrogen-induced cracking (HIC) develops inside steel valve bodies and pressure components exposed to hydrogen sulfide and sour-service environments. The guide explains the causes, failure risks, material-selection requirements, NACE MR0175/ISO 15156 compliance, HIC testing, and inspection practices used to prevent hidden cracking and unexpected valve failure.
DN and PN Meaning in Valves Explained
Learn what DN and PN mean in industrial valves and how these designations define nominal valve size and pressure rating. The guide explains DN-to-pipe compatibility, PN pressure classes, temperature derating, ANSI Class conversion considerations, and practical steps for selecting a valve with the correct size and pressure margin.
BS 5351 Ball Valves vs API 608: What’s the Difference?
Compare BS 5351 and API 608 ball valves by design requirements, pressure ratings, material standards, end connections, testing criteria, and regional acceptance. The correct standard should be selected according to the project specification, operating conditions, applicable piping codes, and customer compliance requirements.
Vapour Pressure Explained for Industrial Valve Systems
Learn how vapour pressure affects cavitation, flashing, two-phase flow, noise, vibration, and valve service life in industrial fluid systems. The guide explains how temperature, fluid properties, and pressure drop influence vapour formation and outlines practical solutions such as maintaining adequate pressure margins, using multi-stage pressure reduction, and selecting anti-cavitation valve trims.
