Directly buried corrugated compensator

Directly buried corrugated compensator (type) is also called underground compensator. It is mainly suitable for axial compensation of directly buried pipelines. It also has super bending resistance, large compensation capacity, long life, etc., so pipelines are not considered Due to the influence of sinking, free expansion and contraction compensation is achieved under the protection of the directly buried corrugated compensation shell and guide sleeve. Other performances are the same as ordinary corrugated compensators. Detailed parameters of direct buried corrugated compensator (type):
Pressure level:.
Product axial compensation amount:
Calculation of thermal deformation of directly buried corrugated compensator (type):
△
Note: This is the expansion coefficient commonly used for carbon steel
is the temperature of the pipeline medium - the ambient temperature during installation
is the length between the two fixed brackets
Precautions for the installation of directly buried corrugated compensator (type):
.In order to use The straight corrugated pipe compensator plays a compensation role. Fixed brackets must be installed at both ends of the compensator to prevent the pipe from moving outward due to the influence of internal pressure and thrust.
.One end of the compensator (referring to the dead end of the directly buried compensator for one-way compensation) should be close to the fixed bracket at one end, and the living head of the compensator should be used to compensate the pipe.
.Set the distance between the two fixed brackets according to the compensation amount. The compensation amount is generally not greater than the pipe diameter.
.During the pressure test process, the compensator must not be stretched.
Directly buried corrugated compensator (type) 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
