Teadit 2235 -- Steam Valves
Steam service requires a material that can withstand high temperatures for an extended period without degradation, and valves require a packing material that is robust and pressure resistant without damaging the valve stem. A major petrochemical plant was having problems with high temperature, superheated steam leaking from valve stems throughout the facility. Leakage of such high temperature steam posed a significant safety risk for all those on site and the leakage was also negatively influencing the quality of the process. In addition, the steam leakage was causing extremely high maintenance costs due to down time. Steam valves can prove to be a challenging application to create an effective, long term seal.
