Does temperature have a big impact on the performance of flexible metal hose?
The influence of temperature on the performance of flexible metal hose is mainly reflected in the following aspects: 1.Corrosion resistance: Changes in temperature will affect the corrosiveness of the conveying medium, thereby affecting the corrosion resistance of the metal hose. Especially in high temperature environments, metal hoses are more susceptible to corrosion, which will shorten their service life. 2.Mechanical properties: High temperature will cause the mechanical properties of...
How does the PTFE lined bellow expansion joint?
The PTFE lined bellow expansion joint is a device that uses a flexible bellows to compensate for the thermal expansion and contraction of the pipeline, absorb vibration and displacement. It is mainly composed of metal bellows, end pipes, flanges and sealing materials. In terms of working principle, the PTFE bellows compensator achieves elastic deformation through its internal corrugated structure. This deformation can occur when the pipeline expands due to heat or contracts due to cooling,...
How to install double sphere rubber expansion joint?
The following points should be noted when installing the double ball rubber expansion joint: 1.Avoid over-displacement: During the installation process, it is strictly forbidden to exceed the displacement limit of the rubber flexible joint to prevent the joint from being damaged or failing. 2.Support and fixation: The pipeline must have a fixed support or fixed bracket, and the force of the fixed bracket must be greater than the axial force to ensure that it will not be pulled off due to...
