Expansion joint Series
Features:
Expansion joints have high tensile and compressive strength, as well as their soft sealing performance and convenient loading and unloading. They are widely used in industries such as metallurgy, power, chemical, water supply and drainage, and sewage treatment, serving as connections between water pumps, valves, and pipelines. When the pipeline transports the medium, due to the environmental factors and the medium, a phenomenon of Thermal expansion will be formed due to the change of the external temperature and the temperature of the medium itself. However, this change in Thermal expansion will cause certain dimensional changes.

Product Details
Large expansion capacity, high temperature resistance, and strong compressive area strength. In the construction of building water supply and drainage engineering, basic concrete pouring or pre buried pipelines are used. In the process of these engineering pipelines being affected by building foundation settlement, equipment resonance, geological changes, and changes in pipeline medium, the distribution of pipelines begins to be stressed, deformed, twisted, and damaged. Pre buried pipelines even break, which brings great inconvenience to the construction unit. In order to overcome these difficulties and ensure the safe operation of pipelines, expansion joints are used Expansion joint: It can expand and contract axially within a certain range, overcoming various angles of displacement, misalignment, expansion, and expansion of the pipeline. The pipeline can freely expand and contract in the extender. Exceeding a greater amount of expansion and contraction in one day has its own limiting effect. To ensure the safe operation of the pipeline.
The construction of each expansion joint is different, but the principle is similar. Generally, expansion joints release shear force through pins, and the number of pins determines the magnitude of the shear force in the expansion joint. If the external force received by the expansion joint is less than the shear force of the pins, the expansion joint also does not play a role. The use of a directional packer can effectively reduce the upward transmission of piston force at the bottom of the tubing string, reduce the force on the upper tubing string of the packer, and reduce its spiral bending degree. Using a combination of directional packers and expansion joints is more effective than simply using
The limited direction packer and the non limited direction packer can better improve the Factor of safety in most working conditions.
