Featured Story – How to avoid the top 10 heat exchanger ‘mistakes’
With around 40 years’ experience of designing and installing heat exchangers – whether as part of a brand-new production line or as an upgrade or replacement to an existing unit – our engineers and sales staff have encountered a wide range of issues on sites. Here are ten of the most common mistakes that can occur as a result of poorly-specified or badly-installed heat exchanger systems – and, most importantly, how you can avoid them on your next project.

Featured Story – Substituting 316L by duplex in a heat exchanger combat erosion
In an organic chemical plant, a high-molecular weight organic acid vaporizer in a shell-and-tube heat exchanger, developed leakage within four months of going into service. The equipment was used to convert liquid acid to vapor under high pressure and above the boiling point of the acid. One of the nozzle pipes from the downstream reactor, which was processing the vapor in the same circuit, also developed a premature leakage.
Featured Story – Spiral or corrugated tube heat exchangers – which is best for...
Since the first spiral heat exchanger was proposed back in the 19th century, they have become synonymous with the treatment of slurries and wastewater; materials which have a high fouling risk, are viscous, or which contain fibers and solid materials. However, in many situations the performance of a corrugated tube heat exchanger is equal to or better than that of a spiral design.
