A peculiarity of this sector is the use of technical and specific elastomers, very resistant to hydrocarbons and to aggressive chemicals in general. Model TENUTE TR/5-ML-PTV has been developed for rotary shaft applications and pressure up to 10 bar.
TENUTE CGI “U” rings are used on clamps to grant sealing performances during pipelines maintenance, whilst TENUTE TSA rings are mainly used in drilling heads. TENUTE IN and IL packing sets are commonly used in hydraulic cylinders with working pressure up to 400 bar. For double effect applications, TENUTE IHN and IAS are available.
Working pressure up to 800 bar and aggressive contact fluids, require double effect TENUTE TE/300 and TI/300 for hydraulic cylinders.
