The Critical Role of Dished Ends in Plastic-Lined GRP Pressure Vessels for Reactor and Scrubbing Applications
Whitepaper by Artur Scott-Bowden
ABSTRACT
This paper examines the structural and operational advantages of dished ends in glass-reinforced plastic (GRP) pressure vessels used in pharmaceutical reactor and fume scrubbing systems. Traditional coned vessel geometries, whilst widely used, introduce fabrication complexity and localised stress concentrations that can affect long-term vessel integrity. Vessels incorporating dished ends with controlled radial transitions offer improved stress distribution, greater fabrication consistency, and enhanced performance under corrosive, high-pressure operating conditions.
