摘要
根据石油钻杆摩擦焊接及焊缝处理技术发展现状,结合API标准对石油钻杆焊缝力学性能的基本要求,并对照中国石油天然气的行业标准,对生产的石油钻杆进行了部分焊缝力学性能统计,分析了石油钻杆的质量保证能力;为提高焊缝的安全系数,提出石油钻杆的摩擦焊接及焊缝热处理工艺的实现方法,并重点指出摩擦焊接与焊缝热处理工艺实现中应注意的问题。
According to the development of the petroleum drill rod friction welding and the welded joint,unifies the API＇s essential requirements to the petroleum drill rod welded joint mechanical properties,and compares the profession standard of the Chinese petroleum natural gas,has carried on the partial welded joint mechanical properties statistics to the production petroleum drill rod,has analyzed petroleum drill rod＇s quality assurance ability.In order to enhance welded joint＇s safety coefficient,proposed that the petroleum drill rod＇s friction welding and the welded joint heat treatment craft realize the method,and key pointed out that the friction welding and the welded joint heat treatment craft realize the question which should pay attention.
