磁力支撑抽油杆扶正器防腐磁条
摘要：
一种磁力支撑抽油杆扶正器防腐磁条，有磁条，磁条呈梯形，截面为矩形，在磁条的外部包覆非金属材料层，非金属材料层融铸在磁条上，非金属材料层的厚度为0.2-1.5mm，非金属材料层不会被井液腐蚀，磁力支撑抽油杆扶正器上的磁条不与腐蚀性介质接触，因此磁条不会被腐蚀，能提高磁力支撑抽油杆扶正器的使用寿命，从而可以提高抽油杆、油管的使用寿命，具有显著的经济效益。
摘要（英）：

The utility model relates to an anticorrosive magnetic stripe of a magnetic-force-supported sucker rod centralizer. The anticorrosive magnetic stripe comprises a magnetic stripe. The magnetic stripe is trapezoidal and the section of the magnetic stripe is rectangular. The external part of the magnetic stripe is covered by a nonmetallic material layer. The nonmetallic material layer is molten and cast on the magnetic stripe. The thickness of the nonmetallic material layer is 0.2-1.5mm. The nonmetallic material layer is not corroded by well fluid. The magnetic stripe on the magnetic-force-supported sucker rod centralizer is not in contact with corrosive media. Therefore, the magnetic stripe is not corroded, the service life of the magnetic-force-supported sucker rod centralizer can be prolonged, the service life of a sucker rod and an oil pipe can be prolonged and the economic benefits are remarkable.
