Force Transmission Pipeline Expansion Joint

short description:

The force-transmission pipeline expansion joint is used for pipeline connection. It is composed of a body, seals, etc., and is sturdy and durable. It can effectively compensate for the expansion and contraction displacement of pipelines caused by temperature changes and fluctuations in medium pressure, preventing the pipelines from deformation and damage. At the same time, it can transmit the axial force to the fixed support to ensure the stability of the system. It is easy to install and is widely used in pipelines for transporting water, oil, gas, as well as in industrial pipeline systems, ensuring the reliable operation of the pipelines.

Product Features and Advantages

Excellent compensation performance: It can effectively compensate for the axial, lateral, and angular displacements of pipelines caused by factors such as thermal expansion and contraction, and changes in medium pressure, protecting the pipeline system from stress damage.

Reliable force transmission: It can evenly transmit the axial force of the pipeline to the fixed support, ensuring the stability of the pipeline system and avoiding pipeline deformation or damage caused by uneven force.

Superior sealing performance: Using high-performance sealing materials and advanced sealing structures, it can ensure the tightness of the pipeline under various working conditions, prevent medium leakage, and improve the safety and reliability of the system.

Strong corrosion resistance: It is usually made of corrosion-resistant materials such as stainless steel and alloy steel, which can meet the transportation requirements of different corrosive media, extend the service life, and reduce maintenance costs.

Convenient installation: With a reasonable structural design, it does not require complex operations or professional tools during installation, which can greatly shorten the installation time and improve construction efficiency. Meanwhile, it is also convenient for subsequent maintenance and replacement.
