Oil sleeve joint sealing and detecting device

Abstract

The invention discloses an oil sleeve joint sealing and detecting device, which comprises an external pressure container and an auxiliary extension rod; sealing plugs are arranged at two ends of the external pressure container and used for sealing the ends of the external pressure container; the auxiliary extension rod is used for being connected at two ends of a test sample; an internal pressure leakage rate detection device is arranged in the external pressure container; the device is used for detecting whether the test sample is leaked and a leakage condition; a third channel, a second channel and a first channel are arranged on the external pressure container; the third channel is used for being connected to an external pressure sensor; the second channel is used for being connected to a pressure pipeline to apply external pressure; a data wire of the internal pressure leakage rate detection device is arranged in the first channel; the data wire is connected to a pressure display; a second through hole and a first through hole are arranged on the auxiliary extension rod; the second through hole is used for being connected to an internal pressure measuring sensor; and the first through hole is used for being connected to the pressure pipeline to apply internal pressure. A joint is detected by adopting the device disclosed by the invention, thus, the sealing reliability of a pneumatic sealing joint for underground application is increased.

AI Technical Summary

Benefits of technology

This patented technology improves the safety and efficiency of joining pipes together during oil or gas drilling operations. It also helps improve the integrity of the connections between different parts of the pipeline system when under high pressures while testing their effectiveness against leaks caused by gases from other areas within the same section.

Problems solved by technology

Technically speaking, it was discovered by researchers who conducted experiments involving different types of threads made from materials like metal (aluminum) which may leaks when exposed under certain high pressures due to factors such as geology). However, previous solutions were unable to accurately detect these cracks caused by stress corrosion cracking.
