TeguflexÒ FFI

Product catalog summary

Overview: The document provides technical specifications and applications for Teguflex® FFI expansion joints, designed for large-sized pipe systems. These joints accommodate axial, lateral, and angular movements, offering high reliability and long life, particularly in cooling water systems at power plants and other industrial applications.

Specifications:

Size Range: DN 1100-DN 3200
Materials: Various combinations of EPDM, Nitrile, Hypalon, and Chloroprene for inner tubes and covers, suitable for different applications such as hot water, mineral oils, and drinking water.
Temperature and Pressure: Maximum temperature of 90°C. Working pressure ranges from 6 to 10 bar, with test and burst pressures exceeding these values.

Design and Construction:

Rubber bellows with full-face rubber flanges and integrated painted steel flanges.
Standard building lengths of 350/450 mm, with custom lengths available upon request.
Carbon steel vacuum rings are part of the design, ensuring they do not contact the fluid.

Applications: Suitable for use in systems requiring small reaction forces, these joints are used in power plants, condensers, and supply lines for pumps and turbines. They help in compensating thermal elongation, correcting misalignment, isolating vibrations, dampening noise, and absorbing pressure surges.

Performance and Movements:

Permissible movements include compression, elongation, lateral, and angular movements, with specific values provided for each DN size.
Spring rates and weights are detailed for each size, indicating the stiffness and flexibility of the joints.

Standards and Certifications: The product complies with ISO 9001 and ISO 14001 standards, ensuring quality and environmental management.
