Featured Story – Improving Aerospace and Aviation Heat Exchanger Performance with Advanced Additive Manufacturing
Heat exchangers are essential for keeping aircraft of all types aloft and functioning properly. They are key components of satellites and drones, for example, where the excessive temperature created by on-board electronics can literally melt them if not controlled. This article, provided by VELO3D, discusses the benefits of additive manufacturing for heat exchanger performance for the aerospace industry.
Featured Story – Using Continuous Helical Flow to Reduce Fouling
It would be an understatement to say that fouling is one of the most costly recurring problems in hydrocarbon processing, and that it hits process heaters and heat exchangers the hardest. Fouling can have a significant impact on heat transfer across the heat exchanger surface, and so likewise on both overall operational performance and total cost of maintenance.
Featured Story – Marc Simoens: a custodian
Marc Simoens is responsible for the quality assurance and quality control of the incoming refurbishment components for pressure containing equipment at Dow’s chemical plant in Terneuzen, The Netherlands. Heat Exchanger World recently caught up with him to talk about his work, the challenges he faces with heat exchanger pipes and tubing, and the advice that he would like to pass on to would-be suppliers, manufacturers, and endusers to Dow.

Featured Story – A failure report from the pulp and paper industry
A pulp and paper plant was facing a major problem when their digester preheaters started leaking, resulting in production loss. The shell-andtube heat exchangers were exposed to steam on the shell side and white liquor on the tube side. The tubes were made of Type 316L stainless steel. The preheaters had replaced the original ones which had performed satisfactorily for ten years. The new ones started leaking within seven months of operation. A detailed failure analysis was hence desirable.
