Porvair Sinterguard®: Surface Modification for Metal Filter Elements

Porvair Filtration Group has launched a range of surface modification technologies that can be applied to metallic filter elements to enhance their material properties in challenging environments, improving filter performance and lifetime.

Ideal for use in refinery or chemical processes where hot or corrosive fluids would otherwise be detrimental to filter lifetime or integrity.

• Porvair Sinterguard^® PHC, extends the life of 316 stainless steel and exotic alloys in highly corrosive fluid environments.
• Porvair Sinterguard^® HTR, extends the service life of 316L stainless steel and exotic alloys at elevated temperatures.

These surface modification treatments can provide a number of benefits, each of which can dramatically reduce whole life operating costs, including corrosion resistance, increased temperature and chemical resistance and improved cleanability.

Andy Bevis, Gasification Business Manager, adds “The incorporation of this patented technology to our material resources realises a substantial increase in the applicability of these materials increasing both overall operational life as well as campaign life. Not only have we witnessed a reduction in high temperature sulphidation corrosion by a factor of at least 6, we have also witnessed improved insitu differential pressure recovery increasing the potential campaign life up to 3 times.”
