Flexitallic's new Baker gasket has been designed to eliminate the risk of accidental release of hydrofluoric acid, a by-product of the production of cleaner burning fuels, from oil refineries. The system incorporates a low stress spiral wound gasket made from PTFE or Flexicarb filler, with a second PTFE seal fitted to the outer ring, and an integral smart detection tag which acts as an early warning of potential problems. The gasket is specifically designed for use on Class 150 and 300 joints with no modification to the flanges or assemblies required. According to the manufacturers, its gasket design delivers a significant improvement in seal integrity with the required bolt load reduced by 15 per cent when used with standard flanges. Furthermore, the extra PTFE layer is said to provide additional protection to the bolts from media attack and confines any emission to inside the flange closure. As an additional failsafe, should a leak occur, the medium is channelled to the detection tag where the detection paint reacts with the media to signal that urgent preventive maintenance is required.
