摘要:
为了研究钢管3PE防腐过程中酸洗工艺的合理参数及控制方法,对钢管酸洗磷酸液浓度、磷酸液与钢管管体的温差、酸洗时间、酸洗方式四个方面进行了分析。结果显示,磷酸液浓度为15%时,磷化膜结晶致密,与母材结合紧密;磷酸液与钢管温度均为60 ℃时,酸洗成膜速度最快;在以上两种条件下,钢管表面酸洗生成3PE防腐的理想膜重(3.0 g/m2)需要20~30 s;喷淋法酸洗效率高,更适合于大直径钢管的3PE防腐生产。
Abstract:
In order to study the reasonable parameters and control methods of the pickling process in the 3PE anticorrosion process of steel pipe, the concentration of pickling phosphoric acid, the temperature difference between the phosphoric acid solution and the body pipe, the pickling time and the pickling method were analyzed. The results show that when the concentration of the phosphoric acid solution is 15%, the phosphating film is densely crystallized and tightly bound to the base material. In addition, when the temperatures between the phosphoric acid solution and the body pipe are both 60 ℃, the formation speed of pickling film is the fastest. Under the above two conditions, the ideal membrane weight(3.0 g/m2) for pickling 3PE anti-corrosion on the surface of steel pipe needs 20~30 s; and the efficiency of spraying pickling method is high, which is more suitable for 3PE anti-corrosion production of large-diameter steel pipe.
