熱噴涂技術在石化行業中的應用

日期:2020-11-07 15:15 人氣:
       在石油、天然氣勘測和鉆采過程中所用設備的關鍵部件如鉆頭、軸、軸承、軸套、灌漿泵等,均受到泥漿、礦石磨料等的二體磨損和三體磨損,并受水、含S(或H2S氣體)的原油或天然氣的腐蝕。對于在這樣惡劣工況下使用的部件,若采用高合金的金屬材料制造,其潛力有限,而且維修成本高。有效辦法是采用耐磨耐蝕的熱噴涂涂層進行表面改性與強化處理。石化工業中設備因腐蝕和磨損對設備安全穩定運行帶來的不利影響會越來越突出,迫切需要提高石油石化工業中開采和加工設備的耐磨性和耐蝕性。通過不同工藝的熱噴涂處理,是零件具有了比本體材料更高的耐磨性、抗腐蝕性和耐高溫等性能,大大提高了零件使用壽命,因此熱噴涂技術在石油石化工業中具有重要地位。
        熱噴涂是一種表面強化技術,是表面工程技術的重要組成部分,熱噴涂技術制備的金屬涂層,經上機試驗,具有良好的耐磨損、耐腐蝕、耐高溫性能,目前已經廣泛應用于石油化工行業中,例如:設備中大功率曲軸、鉆頭、鉆桿、抽油桿等;石油管道中金屬球閥、閥門、閥座、閥桿等。
