Directly buried corrugated compensator, also known as direct buried corrugated pipe, direct buried two-way expander, suitable for only axial displacement in the pipeline. the product has the ability to compensate for transverse displacement and axial to transverse synthetic displacement, but because the compensation amount is small generally only do for axial compensation more play ware characteristics, longer service life, more secure and reliable.
1. in order to make the direct burial is the corrugated compensator to play a compensating role, direct burial corrugated compensator must be set up at both ends of the fixed bracket, to prevent the pipeline by internal pressure thrust influence outward stretching
2. one end of the direct burial corrugated compensator (refers to the one-way compensation of the direct burial compensator dead end) to be close to one end of the fixed bracket, with the compensator live head compensation pipeline.
3. according to the amount of compensation set the distance between the two fixed brackets, compensation is generally not greater than the diameter of the pipe.
4. test pressure process to compensator shall not appear stretching phenomenon.
5. direct buried corrugated compensator is mainly used for axial compensation of direct buried pipeline, with bending resistance. jzm type direct buried corrugated compensator is mainly used for axial compensation, while having super bending resistance, so do not consider the impact of pipe sinking.
6. direct buried corrugated compensator is suitable for only axial displacement in the pipeline, this product has the ability to compensate transverse displacement and axial and transverse synthetic displacement, but because the compensation amount is small generally only do for axial compensation more play its characteristics, longer service life, more safe and reliable.
7. direct buried internal pressure corrugated compensator requires only one corrugated compensator between the two fixed supports, the calculation of the compensator on the support force and the calculation of the single type corrugated compensator on the support force is the same, due to the direct buried internal pressure corrugated compensator in the pipeline to achieve free compensation and simple installation and other characteristics, and therefore popular with the engineering design and installation users. The direct buried external pressure bellows compensator has the double points of external pressure compensator and free compensation direct buried compensator, which is widely used in the construction of heat network pipeline.
