Expansion joint fig. 700 ZETKAMA dn 80 700L080C00

Flexible expansion joints – protecting installations and reducing stress

The figure 700 expansion joint from ZETKAMA is a reliable solution used in industrial, water and heating systems. It is used to compensate for thermal expansion, displacements and vibrations, protecting pipelines and equipment from damage. Made of steel with an EPDM rubber bellows, it provides durability and corrosion resistance. This expansion joint is widely used in hot and cold water installations, compressed air systems, and air conditioning and heating systems.

Construction and application

The figure 700 expansion joint is characterized by a flanged connection compliant with EN 1092-1, which simplifies installation and integration with existing infrastructure. The use of an EPDM rubber bellows guarantees tightness and flexibility over a wide temperature range – from -10°C to +100°C. The design of the expansion joint allows for absorption of pipeline movements in three planes: axial, transverse and angular (up to 15 degrees). This minimizes stress in the installation, which translates into its longer life and safety.

Advantages of the ZETKAMA figure 700 expansion joint

• Durability and reliability: Construction from steel and high-quality EPDM bellows ensures long-term operation even in harsh conditions.
• Wide application: Ideal for water, compressed air and heating and air conditioning systems.
• Easy installation: Flanged connection compliant with EN 1092-1 simplifies the installation process.
• Movement compensation: Absorbs thermal expansion, displacements and vibrations, protecting pipelines from damage.
• Chemical resistance: The EPDM bellows is resistant to many chemicals, increasing the range of applications for the expansion joint.
• Pressure class PN 16: Ensures safe operation in installations with a maximum working pressure of up to 16 bar (depending on diameter).

This model of expansion joint has a nominal diameter of DN 80, an outer pipe diameter of 200 mm and a neutral length of 130 mm and operates in pressure class PN 16.

ZETKAMA figure 700 expansion joints are a proven choice for professionals and individual customers looking for reliable solutions to protect their installations. They provide peace of mind thanks to high-quality workmanship and resistance to failure.
