机械胀管器产品介绍
Mechanical Expander Head Product Introduction
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.
分类与特点 | Classification and Characteristics
机械胀管器根据动力来源可分为电动、气动、手动等不同类型。不同类型的胀管器各具特点，适用于不同的工作环境和需求。
电动胀管器具有效率高、操作简便等优点，适用于大规模生产；而手动胀管器则更加灵活，适用于小批量生产和维修工作。
胀管器还可以根据胀接方式的不同分为前进式胀管器和后退式胀管器等。前进式胀管器是将芯轴插入管内，旋转芯轴向前扩张，完成胀紧
后退出；而后退式胀管器则是在达到胀接程度后，通过反向旋转使胀管芯轴退出管子。
Mechanical Expander Head according to the power source can be divided into electric, pneumatic, manual and other
different types. Different types of expanders have their own characteristics and are suitable for different working
environments and needs.
Electric expander has the advantages of high efficiency and easy operation, which is suitable for mass production; while
manual expander is more flexible and suitable for small batch production and maintenance work.
Expanders can also be categorized into forward expander and backward expander according to the different ways of expansion.
Forward expander is to insert the mandrel into the tube, rotate the mandrel forward expansion, completion of the expansion
after the exit; while the backward expander is to reach the degree of expansion, through the reverse rotation of the expander
mandrel out of the tube.
适用范围 | Scope of application

For example, the expansion pressure of some models of expander can reach 0.170MPa, the expansion speed can reach 1 pipe/min, the inner diameter of the expansion pipe can be Φ8mm Φ32mm, etc. These parameters can be adjusted and selected according to the needs of specific equipment.
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.
