Product introduction：

Gongyi Zhongyuan innovation pipeline equipment Co., LTD.  Production of direct buried corrugated compensator is mainly used for direct buried pipeline axial compensation, at the same time has super bending ability, so do not consider the influence of pipe subsidence, direct buried corrugated compensator in the shell and guide sleeve protection bellows free expansion compensation, other performance with ordinary corrugated compensator the same.  Direct buried compensator structure design is tight, stable operation, long service life suitable for the installation of pipeline buried laying, sealing work done well can be used for more than 30 years, do not need personnel maintenance.It can effectively compensate the axial displacement of the pipeline. Under the double-layer protection of the inner and outer sleeves, the elastic element of the directly buried corrugated compensator can avoid being affected by external factors and ensure the stability of the pipeline operation.

Product feature：

1.In order to make the directly buried corrugated compensator play a compensating role, the two ends of the directly buried corrugated compensator need to set a fixed bracket to prevent the pipeline from being affected by the internal pressure thrust outward stretching.
2.One end of the directly buried corrugated compensator refers to the one-way compensation of the directly buried compensator dead end to close to the fixed bracket at one end of the compensator with the live head compensation pipeline.
3.According to the compensation amount, the distance compensation amount of two fixed supports is generally not greater than the pipe diameter.
4, in the process of pressure test to the corrugated compensator shall not appear tensile phenomenon.
5.JZM type directly buried ripple compensator is mainly used for axial compensation of directly buried pipelines with bending resistance.     JZM type directly buried corrugated compensator is mainly suitable for axial compensation and has super bending resistance, so it does not consider the influence of pipeline subsidence.
6.JZM type directly buried corrugated compensator is suitable for only axial displacement of the pipeline in this product has the ability to compensate transverse displacement and axial and transverse synthesis displacement but because the compensation amount is small generally only as axial compensation can play its characteristics longer service life more reliable.

Directly buried corrugated compensator install：

1. In order to make the directly buried corrugated compensator play a compensating role, fixed supports should be set at both ends of the compensator to prevent the pipeline from being affected by the internal pressure thrust outward stretching.
2. one end of the compensator (refers to the one-way compensation of the buried compensator dead end) should be close to one end of the fixed support, with the compensator head compensation pipeline.
3. Set the distance between two fixed supports according to the compensation amount, and the compensation amount is generally not greater than the pipe diameter.
4. in the process of pressure test to the compensator shall not appear tensile phenomenon.

Directly buried corrugated compensator thermal deformation calculation：

△L=a·t·L=0.0133×360×30=143.6mm;
Note: a is the expansion coefficient usually used for carbon steel;
t is the temperature of the pipeline medium - the ambient temperature when the compensator is installed;
L is the length between the two fixed supports.
