摘要:
为了推动我国石油天然气工程用大直径、高强度感应加热弯管的国产化进程,进行了大直径中频感应加热弯管机的研究。介绍了φ1422mm弯管机结构组成以及中频加热功率等设计参数的计算,并对弯管机机械设计、温度测量及控制等设计要点进行了阐述。同时针对弯管机工作中常见的弯管内弧部位易出现褶皱、外弧壁厚减薄过量、管壁出现裂痕、淬透层深度不够和回弹超差等缺陷提出了应对措施。研制的大直径中频感应加热弯管机经过生产实践证明,其产品外形美观,几何尺寸符合工程要求。
Abstract:
In order to promote localization course of induction heating elbow with large diameter and high strength used in China petroleum and gas projects,research on intermediate frequency induction heating pipe bender was conducted.This article introduced structure of φ1422mm pipe bender and the design parameters calculation for intermediate frequency heating power,and expatiated main design points of mechanical design,measuring and control temperature.Meanwhile,it put forward countermeasures for some defects,such as fold appeared in elbow internal arc,excessive decreasing external arc wall thickness,crack in pipe wall,inadequate depth of hardening and spring back exceed difference,etc.during pipe bender daily working.Production practice proved that intermediate frequency induction heating pipe bender possesses perfect shape,and its geometric size can meet project requirements.
