热张减工艺对高频焊管API圆螺纹抗粘扣性能的影响

Effect of Hot Stretch-reducing Process on Gluing Resistance Property of High Frequency Welded Pipe API Round Thread

如何提高高频焊管API圆螺纹的抗粘扣性能一直是油套管生产厂家的重点研究课题,通过对采用热张减工艺生产的高频焊管作为管坯生产的油套管的API圆螺纹抗粘扣性能进行分析,从热张减工艺对焊管性能的影响、API圆螺纹粘扣失效机理、螺纹参数选配、接箍镀层选用、现场实际作业要求等方面进行了归纳分析,总结了热张减工艺对高频焊管API圆螺纹抗粘扣性能的影响,提出了一些在油套管生产中应注意的问题,具有一定的借鉴意义。

How to improve the gluing resistance property of HFW pipe API round thread is always the key point of the oil casing pipe manufacturers＇ research subject. In this paper it analyzed API round thread gluing resistance of HFW oil casing tube, the billet pipe was produced by hot stretch-reducing process. From the influence of hot stretch-reducing process on welded pipe performance, API round thread gluing failure mechanism, parameters matching, coupling coating selection, the actual requirements and so on carried out the inductive analysis. It also summarized the influence of hot stretch-reducing process on HFW pipe API round thread gluing resistance, proposed some problems that should be paid attention to in the production of tubing and casing, has certain reference significance.
