Description

Technical Field

[0001] The invention relates to the field of protector cleaning, and in particular to a thread protector cleaning device. Background Art

[0002] Thread protectors (or thread protectors) are widely used thread protection devices at both ends of oil casing and pipes. They are mainly used to protect the threads of the male and female joints at both ends of the pipe body from damage during storage, transportation and use. They are mainly composed of protective caps and protective plugs.

[0003] The thread protector (or thread protector) relies on the same type of threaded connection as the pipe body joint, and protects the pipe body thread and prevents dust on the inner wall of the pipe body by tightening the male end cap and the female end plug. However, the inner and outer surfaces of the thread protector (or thread protector) are often difficult to clean due to the crude oil, dust and sand in the well site and the oil on the pipe body during use. The existing method is to use diesel immersion and manual brushing for cleaning, which has low cleaning efficiency and poor effect, especially for thread protectors (or thread protectors) that are adhered to heavy oil. They cannot be cleaned and reused. Taking the Tahe Oilfield as an example, nearly 300,000 sets of thread protectors (or thread protectors) need to be cleaned and reused every year. Manual cleaning cannot meet production needs. If a large number of new thread protectors (or thread protectors) are purchased, the repair cost of oil casing and pipe fittings will be greatly increased. Therefore, the cleanliness of the threaded part of the thread protector (or wire protector) directly affects the protection effect of the pipe body joint thread, especially if the particles cannot be effectively removed, they will damage the pipe body joint thread, seriously affecting the aging of the pipe body thread and increasing the cost of repairing oil casing and pipe fittings.
