机械胀管器产品说明
Mechanical Expander Head Product Description
工作原理 | Working Principle
机械胀管器的工作原理是通过胀管器对管子产生一定的压力，使管子直径胀大，从而消除或减少了管子和管板之间的缝隙，提高管口的密封性能，延长管口的腐蚀时间。胀接过程中，胀管器会塞入管内，通过推进胀杆，使胀杆、胀珠、管子内壁都相互贴紧后，用扳手或胀管机带动胀杆旋转，胀珠在管子内壁进行碾压，迫使管壁金属延展，管径增大。
The working principle of Mechanical Expander Head is to produce a certain pressure on the tube through the expander, so that the diameter of the tube is expanded, thus eliminating or reducing the gap between the tube and the tube plate, improving the sealing performance of the orifice, and prolonging the corrosion time of the orifice. Expanding process, Expanding rod will be stuffed into the tube, by advancing the Expanding rod, so that the Expanding rod, Expanding bead, the inner wall of the tube are all close to each other after the wrench or Expanding System to drive the Expanding rod to rotate, the Expanding bead in the inner wall of the tube to crush, forcing the tube wall metal to extend, the diameter of the tube to increase.
适用范围 | Scope of application
机械胀管器广泛应用于各种需要胀接工艺的设备制造和维修中，如换热器、锅炉、制冷设备、核电站等。特别对于厚管板和大口径管的胀接，机械胀管器展现出了其独特的优势。
Mechanical Expander Head is widely used in the manufacture and maintenance of various equipments requiring expansion process, such as heat exchangers, boilers, refrigeration equipments, nuclear power plants and so on. Mechanical Expander Head shows its unique advantages especially for the expansion of thick tube sheet and large-diameter tube.
优点与局限性 | Advantages and limitations
机械胀管器的优点主要包括胀接均匀、安全可靠、使用寿命长、故障率低等。同时，胀接操作简单快捷，大大缩短了制造或维修时间，减少了化工装置的停产损失，具有很高的经济效益。机械胀管器也存在一些局限性。例如，对于管板厚度超过一定范围的换热器，传统的机械胀接技术可能难以实现全厚度胀接，留下间隙腐蚀的隐患。此外，机械胀管器在胀接过程中可能会对管子造成一定的损伤，需要在使用时注意控制胀接压力和速度。
The advantages of Mechanical Expander Head mainly include uniform expansion, safety and reliability, long service life, low failure rate and so on. At the same time, the expansion operation is simple and fast, greatly reducing the manufacturing or maintenance time, reducing the loss of chemical plant shutdown, with high economic benefits.
