SERIES 251/BT PTFE and FEP lined rubber expansion joints The PROCO Series 251/BT PTFE and FEP lined expansion joints are Specifications Met. PROCO has assigned conservative pressure ratings designed for tough demanding corrosive chemical applications, as to the Series 251/BT and FEP lined rubber expansion joints. The ratings, found in: Chemical & Petrochemical Process Facilities and Highly however, meet the requirements of the Fluid Sealing Association's, Rub- Corrosive Industiral Piping & Pollution Control Systems. The greatest ber Expansion Joint Division Technical Handbook (Sixth Edition), Series usage of the the Series 251/BT is found in the Pulp and Paper Industry C. The pressure ratings for the Series 251/BT PTFE and FEP lined rubber where the ability to resist corrosive attack at elevated temperature expansion joints have been fully tested and are based on a minimum four- and pressure is unmatched by metallic, plastic or other competitive to-one safety factor.
