Scale cleaning device for oil pipe external thread

Abstract

The invention discloses a scale cleaning device for an oil pipe external thread. The scale cleaning device comprises a barrel body and cleaning pieces. The inner wall of the barrel body is provided with an internal thread matched with the oil pipe external thread. The cleaning pieces are arranged on the inner periphery of the barrel body. According to the scale cleaning device for the oil pipe external thread, operation of the scale cleaning device is conducted by screwing the oil pipe external thread into the scale cleaning device and then screwing the oil pipe external thread out of the scale cleaning device, so that cleaning of the oil pipe external thread is facilitated; a wiping effect can be produced on the oil pipe external thread through the cleaning pieces, and hence scale cleaning processing is more thorough; meanwhile, scale can be blocked from falling to the ground around through the cleaning pieces, the follow-up cleaning work amount is reduced, and the pollution of the scale to the surrounding environment is avoided; and compared with the prior art, the cleaning efficiency and quality can be improved, and the stability of an oil pipe connection structure is improved.

Description

technical field [0001] The invention relates to a descaling device, in particular to a descaling device for external threads of oil pipes. Background technique [0002] The oil pipe is a pipeline that transports crude oil and natural gas from the oil and gas layer to the surface after the drilling is completed. It is used to withstand the pressure generated during the extraction process and plays a vital role in the development and production of oil and gas fields. The cleanliness of oil pipe thread is the key element of construction quality. If the thread is too dirty and its integrity is not checked, it will cause the oil pipe to be dissatisfied with buckles, resulting in related shedding or oil pipe leakage. Generally, on-site workers use wire brushes to clean grease, which is extremely inconvenient to use and affects efficiency and cleaning quality. During the cleaning process, most of the dirt falls to the surrounding ground, which increases the workload of subsequent ...

Failure to check the integrity of the thread due to dirty threads will cause the oil pipe to be dissatisfied with thread, resulting in related shedding or oil pipe leakage

Generally, on-site workers use wire brushes to clean grease, which is extremely inconvenient to use and affects the efficiency and cleaning quality. During the cleaning process, most of the dirt falls to the surrounding ground, which increases the workload of subsequent cleaning and easily pollutes the surrounding environment.
