Internal anti-corrosion metal pipe convenient to connect and sleeve

Abstract

The invention relates to the technical field of metal pipes and discloses an internal anti-corrosion metal pipe convenient to connect and sleeve. The internal anti-corrosion metal pipe includes a pipebody; the pipe body further includes an inner layer, an outer coating layer and an embedded layer, the outer coating layer is arranged outside the inner layer, and the embedded layer is arranged inside the inner layer; the bottom of the pipe body is fixedly provided with two base plates; a butt joint ring is fixedly mounted outside the pipe body; and a butt joint ring groove is formed in the leftside of the butt joint ring. According to the internal anti-corrosion metal pipe convenient to connect and sleeve, a filling groove, a reset sleeve rod, a sliding block, a limiting nail, a movable hole and a pull rod are arranged, when a user needs to butt joint two pipe bodies, the left side of one of the pipe bodies is in butt joint with the right side of the other pipe body, and the pull rod is pressed to drive the limiting nail to enter the filling groove, a bearing ring to be inserted into the butt joint ring groove and a sealing ring to enter the pipe bodies, and the pull rod is loosened to enable the limiting nail to enter a limiting groove, so that the two pipe bodies are butt-jointed without welding, and the butting is simple and convenient.

Description

technical field [0001] The invention relates to the technical field of metal pipes, in particular to an internal anti-corrosion metal pipe which is conveniently connected and fitted. Background technique [0002] Anti-corrosion is to protect metal objects that are easy to rust by adopting various means to achieve the purpose of prolonging their service life. Usually, chemical anti-corrosion, physical anti-corrosion and electrochemical anti-corrosion are used. Chemical, electrochemical or physical action, which causes the deterioration and deterioration of metal, is called metal corrosion. Corrosion phenomenon is very common. From the thermodynamic point of view, except for a few precious metals, the corrosion of general metals is a spontaneous process. [0003] Traditional internal anti-corrosion metal pipes often use welding methods for butt joints. Not to mention that it is difficult to disassemble after connection, and professional welders are needed to complete the weldi...
