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.
