胀接原理 | Expansion Principle
YZ-500F型液压胀管机采用液袋式柔性胀接技术，利用增压原理，产生足以使换热管产生塑性变形的超高压胀管膨胀压力。
该压力通过弹性液袋作用于换热管内壁，使换热管发生塑性变形，与管板产生过盈而胀接于管板孔内。
Model YZ-500F Hydraulic Tube Expander System adopts Liquid bag flexible expansion technology, utilizing the principle
of pressurization to generate ultra-high pressure expansion pressure sufficient to cause plastic deformation of the heat
exchanger tube. The pressure acts on the inner wall of the heat exchanger tube through the elastic Liquid bag, which makes
the heat exchanger tube undergo plastic deformation, generates interference with the tube plate and expands into the
hole of the tube plate.
液压胀管机与机械胀管机对比优势
Hydraulic Tube Expander System VS Mechanical Tube Expander System Comparison Advantage
- 高压稳定输出：采用气驱增压系统，最高压力达300MPa，实现全周向均匀胀接，尤其适用于石油化工厚壁管（如φ89×8mm 15CrMo管材）及核电设备大管径加工。
- 复杂场景适配：支持先胀后焊工艺，对任意厚度管板进行全厚度一次性胀接，适配内螺纹管、有缝焊接管等特殊管型，残余应力降低50%
以上，避免间隙腐蚀。
- 高效作业：单人操作8小时可完成3000个孔胀接，配备触屏控制系统与数据日志功能，压力精度误差≤1%。
- Stable output at high pressure: Adopting gas-driven pressurization system, the maximum pressure reaches 300MPa,
realizing full circumferential uniformity of expansion, especially suitable for petrochemical thick-walled pipes
(e.g. φ89×8mm 15CrMo pipes) and large pipe diameter processing of nuclear power equipments.
- Complex scenarios: support for expansion and then welding process, full-thickness one-time expansion of any thickness
of the tube plate, adapted to internal threaded pipe, seam welded pipe and other special pipe types, residual stress
reduction of more than 50%, to avoid interstitial corrosion.
- Efficient operation: single operator can complete 3000 holes expansion in 8 hours, equipped with touch screen control
system and data logging function, pressure accuracy error ≤1%.
