Expansion joint as the pipeline accessories, is used to compensate the temperature difference and the additional stress and is a kind of attachment, the stress along the axis direction of expansion in order to achieve axial length compensation, so the normal operation of the pipeline plays a critical role in the. But at the same time it is used in a piping system components, sometimes due to expansion of expansion joint is relatively general crack and fracture phenomena.

In order to ensure the safe operation of equipment, equipment management personnel in March 6th, carbonization workshop to check the expansion joint set four sets of transformation system. In fact, this year has never stopped, especially in the hot summer, some parts of the temperature up to 300 degrees, at a distance of one meter distance still can obviously feel the discomfort caused by thermal radiation. However, the workshop staff to overcome the adverse conditions, regularly carry out a careful examination of the expansion joint, in order to ensure the timely detection of problems, ensure the safe use of equipment.
