Problems solved by technology

[0004] The above-mentioned steel-plastic composite pipe has the following disadvantages during use 1. When the above-mentioned steel-plastic composite pipe is paved and connected, it can only be connected between adjacent pipe bodies through its socket structure. The butt joint structure is single and the connection is stable. 2. The above-mentioned steel-plastic composite pipe can only be sealed by its internal sealing structure during use. The sealing structure may age after long-term use, which will affect the sealing effect of the joint. Therefore, we propose A spliced ​​steel-plastic composite pipe

Abstract

The invention discloses a spliced steel-plastic composite pipe, and belongs to the technical field of steel-plastic composite pipes, the spliced steel-plastic composite pipe comprises a pipe body, the pipe body is formed by compounding a base body pipe and a lining pipe, the lining pipe is located in the base body pipe, one end of the outer side wall of the pipe body is fixedly connected with a bell mouth, and one side, close to the bell mouth, of the outer side wall of the pipe body is fixedly connected with a connecting block A; a screw is fixedly connected to the surface of the connecting block A, a connecting block B is fixedly connected to the side, away from the bellmouth, of the outer side wall of the pipe body, the side, away from the bellmouth, of the pipe body is aligned with the bellmouth of the adjacent pipe body and inserted into the pipe body, the screw fixed to the surface of the connecting block A penetrates through the interior of the connecting block B after the pipe body is inserted, and at the moment, a nut is screwed into the outer wall of the screw and tightened; the connecting blocks A and the connecting blocks B are fixedly connected together through cooperation of the screws and the nuts, then the auxiliary reinforcing effect on the connecting positions of the adjacent pipe bodies is achieved, and compared with a traditional single connecting structure, the connecting stability of the connecting positions of the pipe bodies is improved.

Description

technical field [0001] The invention relates to the technical field of steel-plastic composite pipes, in particular to a spliced ​​steel-plastic composite pipe. Background technique [0002] Steel-plastic composite pipe, the product is based on seamless steel pipe or welded steel pipe, the inner wall is coated with high adhesion, anti-corrosion, food-grade hygienic polyethylene powder coating or epoxy resin coating, using pre-treatment, preheating, internal coating The water supply galvanized inner plastic-coated composite steel pipe made by the process of filling, leveling and post-treatment is an upgraded product of the traditional galvanized pipe and is widely used. [0003] Patent No. CN 204187150 U discloses a socket-connection-lined plastic-steel-plastic composite pipe, through which the sealing ring provided on it is in sealing contact with the horn-shaped socket lining pipe of the rear steel-plastic composite pipe. It is connected with socket socket, taper seal and ...
