JST Valve Product Engineering A tantalum ball valve is not a routine upgrade from stainless steel. It is a highly specialized solution for process lines where corrosion has become the dominant lifecycle problem. This guide explains where tantalum ball valves make engineering sense, where they do not, how tantalum compares with Hastelloy, titanium and zirconium,…
Severe Service Failure Analysis | HPAL Nickel Processing When a valve fails in an HPAL plant, the problem is rarely just “corrosion.” Acid concentration, slurry velocity, temperature, solids, pressure cycling and valve geometry usually work together. This article maps the most common HPAL valve failure mechanisms to the process location where they occur, then shows…
2026 Marine Regulation Update A new regulatory phase for ammonia-powered shipping began on 1 July 2026. For shipyards, fuel-system integrators and valve buyers, the practical question is no longer whether ammonia will be considered as a marine fuel. The question is whether each valve can safely isolate, purge and control it. This engineering briefing reviews…
