     管道因溫度變化產(chǎn)生熱脹冷縮現(xiàn)象，管線受熱膨脹變形，受冷收縮發(fā)生斷裂，為了避免這種現(xiàn)象產(chǎn)生的管線破壞叫熱力補償。一般在管段加入補償器，管線因溫度變化而伸長或縮短的配件，熱力管線上所利用的主要有波形補償器和波紋管兩種。
CS熱力管道伸縮器特點
管道伸縮器的鏈接主要有法蘭連接、焊接兩種，直埋式伸縮器（非地溝、設井安裝時）一般采用焊接。管道伸縮器具有良好的綜合性能，所以它廣泛用于化工、建筑、給水、排水、石油、輕重工業(yè)、冷凍、衛(wèi)生、水暖、消防、電力等基礎工程
使用范圍：CS型熱力套管伸縮器是電廠、核電、發(fā)電、煉鋼、扎鋼及污水處理工程等給排水管道的必備 設備，它的使用溫度200℃～350℃，它的使用壓力1.0～2.5MPa.
安裝注意事項：
1、安裝前松開壓盤螺栓，將伸縮器拉長至安裝長度（見下表），然后對角法擰緊螺栓，切勿壓偏。
2、本伸縮器應安裝在管道的直線段上兩個固定支架之間，為保證伸縮器正常伸縮并防止拉脫，應設有導向支架及檔件。

     A pipeline temperature changes heat bilges cold shrink phenomenon, pipeline expands deformation, mixed shrinkage occurs fracture, in order to avoid this kind of phenomenon called thermal compensation for damage of the pipeline. General in the pipeline section to join compensator, pipeline for temperature changes and elongation or shorten accessories, thermal pipe used mainly waveform compensator and corrugated pipe two kinds.
CS thermal piping valve is characteristics
Piping valve is mainly have the link flange connection, welding two kinds, buried type valve is (not edible, set well installation) general welding. Pipeline instruments have good telescopic comprehensive performance, so it is widely used in chemical industry, building, water supply, water drainage, oil, heavy industries, frozen, health, plumbing, fire control, power and other basic engineering
Use scope: CS type thermal expansion pipe casing is power plant, nuclear power, power generation, steel, steel and wastewater treatment engineering firm such as water supply and drainage pipe the necessary equipment, it's using temperature 200 ℃ ~ 350 ℃, its use pressure 1.0 ~ 2.5 MPa.
Installation note:
1, before installation, loosen the pressure plate bolt, the valve will be stretched to install length (see chart), and then the bolt on diagonal method, don't pressure partial.
2, the expansion pipe should be installed in the pipeline of straight section between two fixed bracket, to ensure that the valve and prevent pulled off the normal expansion, should have guide bracket and file a.
