中文摘要：为解决盘绕连续管在现场管-管对接中由于管体弯曲，组对困难的问题，研制了一种用于连续管管体局部矫直机。该设备采用液压驱动，利用靠模和三点弯曲来实现连续管无损伤的矫直。通过变化靠模和支点间距可实现对金属连续管所有规格的矫直。
英文摘要：In order to solve the problem of tube aligning in butt welding for coiled tubing in field, a straightening machine for coiled tubing was designed. This machine was driven by hydraulic pressure, which can realize the straightening coiled tubing without damaged by profiling and three-point bending. In addition, this machine can straighten all sizes of coiled tubing by changing profiling and pivot distance.
