Video: Compensate For Temperature Fluctuations And Pressure Pulse Loads
The core component of the cutting rings from Stauff is an elastomer seal that is positioned in the rear area of the 24 ° cone. An O-ring arranged between the cutting ring and the pipe secures the second possible leakage path. By using FKM as the sealing material, the sealing system should also be able to be used at high temperatures or aggressive media.
The cutting rings themselves are designed with a zinc / nickel surface as standard. With more than 1200 hours resistance to red rust / base metal corrosion in the salt spray chamber according to DIN EN ISO 9227, it should provide reliable corrosion protection. A central requirement in the developer specifications was to install the connection system as intuitively as possible. It is guaranteed by an increase in force at the end of assembly - in which the cutting ring comes to rest on the end face of the screw body.
Stable and fast pipe constructions
The soft-sealing cutting rings of the FI-WDDS series are available for all common metric pipes with outside diameters between 6 mm and 42 mm. Some of them clearly exceed the ISO pressure specifications and are suitable for nominal pressures up to 500 bar in the light series or up to 800 bar in the heavy series.
Another advantage of using the soft-sealing cutting rings is that they or their service provider for tube assembly and assembly can significantly reduce the time and cost-intensive inspection work. (br)
