[0002] Test tubes with non-welded pre-treated structures are widely used in various testing scenarios, particularly where high reliability and cleanliness are required. For example, in hydraulic systems, test tubes are used to measure pressure at various points and serve as conduits for fluids. Furthermore, in fields such as environmental monitoring and water quality testing, there is also a demand for non-welded pre-treated test tubes for rapid testing.

[0003] In the prior art, some test tubes are usually connected and fixed by threaded connections in order to extend the length of the tube body. However, threaded connections are prone to structural wear, and the connection of the test tube may become loose after repeated use. In addition, the entire test tube needs to be replaced, which increases replacement costs.

[0004] Therefore, we propose a test tube with a non-welded pre-treated structure. Utility Model Content
