As the professional manufacture, we would like to provide you high quality Pengfa U-shaped Pipe Compensators. And we will offer you the best after-sale service and timely delivery. U-shaped Pipe Compensators, also known as expansion joints or expansion joints, are mainly used to compensate for thermal expansion and contraction of pipelines caused by temperature changes. If the pipe is not completely free to expand or contract when the temperature changes, thermal stresses will develop in the pipe. This stress must be considered in the pipeline design, otherwise it may cause the rupture of the pipeline and affect the normal production. As an important part of pipeline engineering, compensators play an important role in ensuring the long-term normal operation of pipelines.
