一种注水井油管电保护器及其制备方法
摘要：
本发明属于金属材料腐蚀防护领域，特别涉及一种注水井油管电保护器及其制备方法。所述电保护器包括电保护体(4)、外护管(3)和内护管(5)；所述电保护体(4)呈管状，电保护体(4)的内部插合连接内护管(5)，内护管(5)的壁上一体成型的设置有若干槽孔(6)；电保护体(4)的外部设置有外护管(3)，电保护体(4)与外护管(3)之间插合连接；所述外护管(3)的两端分别通过上接头(1)和下接头(2)与被保护油管螺纹连接。所述电保护体(4)为铝合金，该合金的成分按质量百分比为：Zn：4.0-4.7％；In：0.015-0.030％；Mg：1.2-2.0％；Ti：0.04-0.1％；Ga：0.01-0.02％；杂质总量≤0.3％；余量为铝。本发明的注水井油管电保护器经济有效、使用简便，防护效果好。
摘要（英）：

The invention belongs to the field of metal material corrosion protection and particularly relates to an electric protector for injection well oil tubes and a preparation method thereof. The electric protector comprises an electric protection body (4), an outer protection tube (3) and an inner protection tube (5), wherein the electric protection body (4) is tubular, the inner protection tube (5) is connected inside the electric protection body (4) through insertion , and the wall of the inner protection tube (5) is integrally provided with a plurality of slots (6); the outer protection tube (3) is arranged outside the electric protection body (4), and the electric protection body (4) is connected with the outer protection tube (3) through insertion; the two ends of the outer protection tube (3) are respectively in threaded connection with oil tubes to be protected. The electric protection body (4) is made of aluminum alloy which comprises the following components by mass percentage: 4.0-4.7 percent of Zn, 0.015-0.030 percent of In, 1.2-2.0 percent of Mg, 0.04-0.1 percent of Ti, 0.01-0.02 percent of Ga, less than 0.3 percent of total impurities and balance of aluminum. The electric protector for injection well oil tubes provided by the invention is economic and effective, is simple and convenient to use and has a good protection effect.
