Abstract

本实用新型提供一种整体直连加厚钻杆,由接头和管体组成,管体的两端设有接头,接头部位是由接头周围直接加厚形成,所述接头与管体之间无焊缝,管体与接头采用金属材料制成;其优点是增强了接头强度,不需焊接,接头与管体采用同一材料从而增强了整个钻杆的强度,避免了紊流,刺穿,刺漏的质量问题。

Description

一种整体直连加厚钻杆
技术领域
本实用新型涉及一种钻杆,具体涉及一种整体直连加厚钻杆。
背景技术
目前钻杆是由无缝钢管进行两端加厚,然后再两端分别焊接带有外螺纹和内螺纹的接头,为了保证焊缝的强度就要通过增加横截面积来保证钻杆的强度,这样就增加了接头的厚度,降低了整体钻杆重量,接头与管体还不是同一材质,而且容易发生紊流,刺穿,刺漏等质量问题。
实用新型内容
为解决现有技术的不足,本实用新型提供一种整体直连加厚钻杆。
本实用新型所采取的技术方案是:一种整体直连加厚钻杆,由接头和管体组成,管体的两端设有接头,接头部位是由接头周围直接加厚形成,所述接头与管体之间无焊缝。
管体与接头采用金属材料制成。
本实用新型的有益效果是:增强了接头强度,不需焊接,接头与管体采用同一材料从而增强了整个钻杆的强度,避免了紊流,刺穿,刺漏的质量问题。
附图说明
附图1为本实用新型的结构示意图。
其中:1接头、2管体。
具体实施方式
下面结合附图对本实用新型作进一步说明。
如图所示,一种整体直连加厚钻杆,由接头1和管体2组成,管体2的两端设有接头1,接头1部位是由接头1周围直接加厚形成,所述接头1与管体2之间无焊缝。
管体2与接头1采用金属材料制成。

Claims (2)

1.一种整体直连加厚钻杆,由接头和管体组成,其特征在于管体的两端设有接头,接头部位是由接头周围直接加厚形成,所述接头与管体之间无焊缝。
2.根据权利要求1所述的一种整体直连加厚钻杆,其特征在于管体与接头采用金属材料制成。
