摘要:
A method for creating an improved coiled tubing is provided, comprising cleaning a sheet metal workpiece using an electroplasma process to remove oxide scale and other contaminants on surfaces of the workpiece; applying a first metal coating to the workpiece using the electroplasma process; forming the sheet metal workpiece into a tube having abutting edges to form a seam; welding the seam to complete the formation of the tube; grinding the seam to establish a smooth exterior surface on the seam; applying a second metal coating to the seam of the tube using the electroplasma process; and coiling the tube around a spool.
摘要(中):
提供了一种用于创建改进的连续油管的方法,包括使用电镀工艺清洁钣金工件以去除工件表面上的氧化皮和其它污染物; 使用电镀工艺将第一金属涂层施加到工件上; 将所述钣金工件形成为具有邻接边缘的管以形成接缝; 焊缝焊接完成管的形成; 研磨接缝以在缝上建立光滑的外表面; 使用电镀工艺将第二金属涂层施加到管的接缝; 并将管缠绕在线轴上。
