摘要： 油套管接箍磷化是油套管制造过程中的关键工序,目前多采用的是强酸、强碱人工预处理,磷化质量差、效率低、操作环境恶劣、废液排放困难、污染环境,而且还会腐蚀接箍本体。采用超声波技术对接箍表面进行超声波清洗、漂洗及清水漂洗新工艺预处理,有效提高了磷化效果、螺纹的抗黏扣能力和生产效率,降低了能耗,节约了生产成本,实现了接箍磷化的机电一体化控制。

Abstract: The phosphating of annulus coupling is critical to annulus manufacturing. Conventionally, coupling phosphating is carried out by use of strong acid or strong alkali artificially, so the phosphating quality is poor and the efficiency is not satisfying. As well the operating environment is bad, waste liquid is difficult to be discharged and the environment is thereby polluted, and meanwhile the couplings might be corroded. Compared with the commonly used cleaning methods, the ultrasonic technology is for the first time proposed to be applied for coupling cleaning, which fills the blank of phosphating with pollution-free and automatic foreprocess in China, fulfills the electromechanical integration control of coupling, improves efficiency, and reduces labor intensity of operators.

Key words: casing and tubing, coupling, phosphating, ultrasonic cleaning
