摘要:
为了提高油气输送管道用直缝埋弧焊管拉伸性能的合格率和性能稳定性,利用扩径率对屈服强度有显著影响这一规律,采用信息系统和数理统计分析方法,提出一种制管技术方案和实现方式。并通过实例验证了该技术方案的可行性。验证结果表明,在实际生产中可通过建立焊管拉伸性能与扩径率数据库的函数关式,针对每批原料选择不同的扩径率,实现焊管拉伸性能的准确控制。该技术已申请发明专利(ZL 201310202717.X)。
Abstract:
In order to improve the qualified rate and performance stability of tensile performance of longitudinal submerged arc welded pipe which used for oil and gas transportation, according to the rule that the expansion rate significantly affects the yield strength, adopting information system and mathematical statistic analysis method, a kind of pipe manufacturing technical scheme and implementation was put forward, and the feasibility of this technology scheme was verified by examples. The results indicated that in actual production, it can built function relation between tensile performance and expansion rate database, selecting different expansion rate according to each batch raw material, to realize accurate control for welded pipe tensile performance. This technology has applied for a patent(ZL 201310202717.X).
