[0002] High-pressure pipe is a kind of pipe that can withstand pressure and is used to transport liquids. There are many types of pipes, including steel pipes, copper pipes, stainless steel pipes, and others. It is mainly used to manufacture high-quality carbon structural steel and alloy structural steel high-pressure pipes for steam boiler pipes with high pressure and above. In the process of transporting liquid media through high-pressure pipelines, filters need to be equipped to filter impurities from the media as needed.

[0003] After the high-pressure filter tube filters the transported liquid medium, when some of the filter holes in the internal filter tube are blocked, the pressure inside the high-pressure filter tube will further increase, and the liquid will drive the pipeline to vibrate when it is transported inside the pipeline. The vibration combined with the pressure inside the pipeline will cause the pipeline connection to loosen and affect the sealing effect of the pipeline. Utility Model Content

[0019] A filter tube 8 is movably inserted into the inner top of the outer tube body 1. The filter tube 8 is located on the outer tube wall inside the outer tube body 1 and is penetrated with a plurality of filter holes 9 at equal intervals. The filter tube 8 extends to the outer tube wall at one end of the inlet pipe 3 and is fixedly sleeved with a support ring 10. A matching support groove 11 is provided on the inner wall of the inlet pipe 3 corresponding to the support ring 10, and an internal thread groove 12 is provided on the inner top wall of the support groove 11. A connecting pipe 13 is inserted into the inner part of the internal thread groove 12.
