Problems solved by technology

[0002] At present, in the field of oil pipelines, oil well pipes need to be equipped with protective caps for transmission to prevent damage to oil well pipes due to collisions during transmission. Adhesion occurs, and when used, the protective cap needs to be removed. The conventional method is to manually disassemble, which requires a lot of manpower and material resources, and the disassembly speed is low.

Abstract

The invention discloses an oil well pipe protective cap. The oil well pipe protective cap comprises a thread connecting head. An oil coating layer is installed inside external threads of the thread connecting head. A cap body is installed on the upper portion of the thread connecting head. The cap body is matched with the external threads. At least one positioning groove is formed in an inner cavity of the thread connecting head. The oil well pipe protective cap has the advantages of being convenient to dismantle.

Description

technical field [0001] The invention relates to an oil well pipe protective cap, which is used for protecting the oil well pipe. Background technique [0002] At present, in the field of oil pipelines, oil well pipes need to be equipped with protective caps for transmission to prevent damage to oil well pipes due to collisions during transmission. Adhesion occurs, and when used, the protective cap needs to be removed. The conventional method is to manually disassemble, which requires a lot of manpower and material resources, and the disassembly speed is low in efficiency. Contents of the invention [0003] In order to overcome the deficiencies of the above-mentioned prior art, the object of the present invention is to provide a protective cap for oil well pipes, which is characterized by easy disassembly, time-saving and labor-saving. [0004] The purpose of the present invention is achieved in the following way: a protective cap for oil well pipes, including a threaded j...
