    ＃Gongyi Zhongyuan Innovation Pipeline Equipment Co., Ltd Strive for perfection Casing expansion Key points of knowledge planning:：CS Thermal pipe expansion is suitable for conveying steam and hot water lines at temperatures not higher than 450 degrees. It is composed of a telescopic sleeve, a pressure plate and a telescopic body. It is mainly used in the steam pipeline to compensate the displacement caused by thermal expansion and contraction of the steam pipeline. The CS thermal pipe expansion device is composed of a telescopic sleeve, a pressure plate and a telescopic body.

   The inner tube material of the thermal pipe expansion device is divided into cast iron thermal expansion device. (HT), galvanized thermal expansion (DX) and steel thermal expansion (SF) three kinds. CS type thermal pipe expander produces thermal expansion and cold contraction phenomenon due to temperature change in the pipeline, the pipeline is heated and expanded and deformed, and the pipeline is fractured by cold contraction. In order to avoid this phenomenon, the pipeline damage is called thermal compensation. Generally, the compensator is added in the pipe segment, and the accessories that the pipeline extends or shortens due to temperature changes. The main types of waveform compensator and bellows are used in the thermal pipeline
