Trelleborg Identifies Sealing Materials to Extend Seal Life in High Fire Risk Oil & Gas Hydraulic Applications
HFC fluids, or water glycols, are the most commonly used fire-resistant hydraulic fluids and with their higher ignition temperature they are increasingly being used instead of HLP media or even being made mandatory in hydraulic oil & gas applications with a high fire risk. A research program by Trelleborg Sealing Solutions has resulted in identification of alternative sealing materials that give better performance and extended life in HFC fluids.
Eric Bucci, Oil & Gas Segment Manager Americas, Trelleborg Sealing Solutions, says: “Oil & gas hydraulic applications often involve demanding dynamic movements, for instance in the case of offshore motion compensation cylinders, and due to long strokes, sealing systems can be subjected to significant wear.
Compared to oil-based HLP media the water base of HFC fluids typically increases seal wear. As oil & gas applications increasingly use HFC fluids and length of life needs to be extended to avoid costly downtime, it is imperative that we provide operators with information on the optimum sealing material for HFC fluids.”
