Example of corrugated compensator installation schematic:
Main components:
Bellows: This is the core part of the compensator, constructed from multiple layers of metal corrugations that allow for axial, lateral or angular displacement.
Flanged or welded end: The way the ends of the compensator are connected, possibly in the form of flanges or direct welding, for connection to the pipe.
guide bracket: Located on the pipe near the compensator, ensuring that the pipe moves only axially when it expands or contracts, preventing lateral offset.
Fixed bracket: Located at a distance between the ends of the compensator to support the pipe and withstand the reverse thrust generated by the compensator.
limiting device: Limiting devices may be included in some designs to limit the maximum displacement of the compensator and prevent overstretching or compression.
Bolts and spacers: When used for flange connection, ensure the tightness and tightness of the connection.
Installation points:
Connection of pipe to compensator: Make sure the compensator is aligned with the connection of the pipe, maintaining straightness and concentricity.
Position of guide bracket: The guide bracket shall be placed near the compensator to control the linear motion of the pipe.
Distance of fixed bracket: The fixed bracket shall be determined according to the type of compensator and the design pressure of the pipe to withstand the thrust of the compensator and the weight of the pipe.
Pre-stretched or pre-compressed: In some cases, the compensator needs to be pre-stretched or pre-compressed at installation to accommodate the expected amount of expansion of the pipe at operating temperatures.
Installation direction: For directional compensators (such as unidirectional compensators), ensure that they are installed in the correct direction and conform to the direction of media flow.
Bolt tightening: Ensure that the bolts are evenly tightened at all joints to avoid overtightening on one side and causing the compensator to deflect.
Installation diagrams will typically include:
Layout drawing of pipe and compensator.
Position of individual brackets and limiting devices.
A detailed description of the connection method (e.g. bolt distribution for flanged connections).
Notes on special installation requirements (e.g. pre-stretch amount, maximum allowable displacement, etc.).
Keep in mind that specific installation details and requirements will vary depending on the type of compensator, the operating conditions of the pipe, and design specifications, so it is important to read and follow the compensator installation guidelines carefully before installation.
