Directly buried corrugated compensator

One purpose
Directly buried corrugated compensator
is mainly used for axial compensation of directly buried pipelines and has bending resistance.
Secondary use instructions
Directly buried corrugated compensator
is mainly suitable for axial compensation and has super bending resistance, so the influence of pipeline sinking is not considered. The directly buried corrugated compensation shell and the protection of the guide sleeve realize free expansion and contraction compensation, and other properties are the same as ordinary corrugated compensators.
Deformation calculation

Note is the expansion coefficient commonly used for carbon steel
is the temperature of the pipeline medium, the ambient temperature during installation
is the distance between the two fixed brackets Length
Three installation precautions
To make the directly buried corrugated compensator play a compensating role, fixed brackets must be installed at both ends of the compensator to prevent the pipeline from moving outward due to the influence of internal pressure and thrust.
One end of the compensator refers to the dead end of the directly buried compensator for one-way compensation, which should be close to the fixed bracket at one end, and the living head of the compensator is used to compensate the pipe.
Set the distance between the two fixed brackets according to the compensation amount, which is generally not greater than the pipe diameter.
During the pressing process, the compensator must not be stretched.
