Heat Exchanger Seal Ring Suppliers

Destec supplies seal rings for heat exchanger closures, an application area where the combination of pressure, temperature cycling and frequent opening for cleaning or inspection makes a conventional compressible gasket a poor long-term fit. The reusable, all-metal seal ring design means a heat exchanger head can be removed and refitted for routine tube-side cleaning without needing a new gasket sourced and fitted at every opening, cutting both material cost and turnaround time during a maintenance outage. Existing heat exchanger closures that have proved troublesome with conventional gaskets can usually be converted on site to incorporate a Destec seal ring, with the design modification handled by Destec's engineering team and the practical work carried out using portable machines. This conversion route suits heat exchangers with a history of gasket leakage or joint face damage from repeated re-gasketing over the life of the equipment.
