Abstract

油田所用的一种直缝焊式外加厚油管。解决了油管成本高的问题。其特征在于:管体(2)是直缝焊接成的,在管体(2)两端用摩擦焊接上(3)外加厚接头(1)。具有油管成本低的特点,具有可观的经济效益。

Description

一种直缝焊式外加厚油管
技术领域:
本实用新型涉及油田采油及注水方面所用的一种油管,属于一种直缝焊式外加厚油管。
背景技术:
油田在石油开采过程中,采油及注水方面所用的管大多为油管,用量是很大的。目前常用的油管大多为无缝钢管,价格较高,加大了原油的开采成本;况且由于接头丝扣在使用过程中的磨损,使得在油管接头处容易断裂,造成生产上的浪费。
发明内容:
本实用新型的目的是克服上述技术的不足而提供成本低且油管接头处不易断裂的一种直缝焊式外加厚油管。
本实用新型所采用的技术方案是:该油管由管体及接头组成,管体是直缝焊接成的,在管体两端用摩擦焊接外加厚接头。
本实用新型与已有技术相比的有益效果是:由于该油管体是用直缝焊接方法来生产的油管,使得采油或注水不必使用无缝钢管,价格大大降低,从而减少了原油开采成本;且在管体两端用摩擦焊接上外加厚接头,使得接头处不易在根部断裂,避免不必要的损失,具有可观的经济效益。
附图说明:
图1是本实用新型的结构示意图。
1—外加厚接头,2—管体,3—摩擦焊接。
具体实施方式:
下面将结合附图对本实用新型作进一步的说明:
如图1所示,该油管由管体2及接头1组成,管体2是用直缝焊接方法而成的,使得采油或注水不必使用无缝钢管,价格大大降低,减少了原油开采成本;况且在管体2两端用摩擦焊接3外加厚接头1,增加了接头1的压力、拉力和强度,使得接头1处不易在根部断裂,避免不必要的损失,从而可以节省大量工时和维修费用,具有可观的经济效益。
实际使用时,与常规油管使用相同。
