Background

The pipe compensator is also called as a telescopic device or a telescopic joint or an expansion joint and is mainly used for compensating expansion and contraction caused by temperature change of a pipe. Thermal stresses will develop in the pipe if the pipe is not fully free to expand or contract when the temperature changes. This stress must be taken into account in the pipe design, otherwise it may lead to cracking of the pipe, affecting the normal production run. As an important component of pipeline engineering, the compensator plays an important role in ensuring long-term normal operation of the pipeline.

The existing metal corrugated compensator is usually fixed with an upper support rod between a left flange and a right flange to restrain a middle corrugated pipe in order to protect and shape the corrugated compensator, when a thermal tube expands with heat and contracts with cold, the two flanges can be in sliding fit with the support rod to extrude the corrugated pipe so that the corrugated pipe can extend along the axial direction to absorb the stress generated when the thermal tube expands with heat and contracts with cold, although the mode can absorb the stress generated by the thermal tube, the motion of the corrugated pipe is limited to a certain extent, so that the corrugated pipe can only displace along the axial direction when absorbing the stress, can not displace angularly, and can not fully exert the self function thereof, thereby having certain defects, improvements are needed.
