Expansion joint flanged type ZKB DN150 149B12559C

Vibration isolators – reduction of vibrations and noise in installations

The ZKB type flanged vibration isolator is a structural element designed for piping installations, the main task of which is to dampen vibrations and compensate for length changes. This reduces the transmission of noise and vibration to the building structure, and also protects pipelines from damage caused by stress. Made of EPDM rubber and galvanized steel, it combines flexibility and durability, ensuring long-lasting and reliable operation.

Construction and application

The ZKB connector is widely used in heating, ventilation, air conditioning systems and industrial installations. Its construction based on the combination of a rubber damping element with steel flanges allows for easy installation and integration with existing infrastructure. The flanges are drilled according to PN10 and PN16 standards, ensuring compatibility with various types of pipes and fittings. The use of ZKB connectors allows for compensation of thermal expansion of pipelines, reduction of noise generated by operating equipment (e.g. pumps, fans) and protection of the installation against the effects of vibration.

Key features and benefits

• Vibration damping: Reduction of vibration transmission to the building structure, which improves comfort and minimizes the risk of damage.
• Movement compensation: Ability to compensate for expansion and contraction of pipelines resulting from temperature changes, which prevents the formation of internal stresses.
• Noise reduction: Reduction of noise generated by operating equipment, which contributes to improving the acoustic conditions in the rooms.
• Strength and durability: Made of high-quality materials (EPDM, galvanized steel) guarantees long-lasting and reliable operation even in difficult operating conditions.
• Easy installation: Flanged design facilitates integration with existing piping infrastructure.
• Wide range of applications: Possibility of use in various types of installations (heating, ventilation, air conditioning, industrial).
• Safety: Protection of the installation against conduction of electric current (depending on the application).

The connector is made of EPDM rubber, and the flanges are steel and galvanized. The maximum working pressure is 1.6 MPa, and the maximum working temperature is 95°C. The flanges are drilled according to PN10 and PN16 standards.

Additional options available on request include flanges made of stainless steel (304, 304L, 316, 316L) and drilling according to PN25 or ANSI 150 standards. It is important to remember to select the connector correctly for the specific working conditions of the medium and the parameters of the installation.
