Description

Technical Field

[0001] The utility model relates to the technical field of direct-connected casing pup joints, in particular to a direct-connected casing pup joint. Background Art

[0002] Direct-connect casing nipples usually refer to petroleum casing products that are outside the standard length. They are designed and manufactured according to different usage requirements in actual use.

[0003] When conveying different media, long-term use of the direct-connected sleeve short section will cause impurities to accumulate on the inner wall. Excessive accumulation of impurities will affect the circulation effect of the medium. The existing direct-connected sleeve short section uses the sleeve short section body, mounting block, bracket, reset spring, movable block, movable plate, disc and bristles to clean the inner wall of the direct-connected sleeve short section. However, since the medium flows for a long time, the elasticity of the reset spring may disappear under long-term pressure, resulting in the inability to drive the disc and bristles to reset when the medium stops flowing, resulting in poor cleaning effect. After searching, it was found that the technical solution provided by the utility model with application number 202321876641.4 also has the above-mentioned problems. Utility Model Content
