Description

PE pipe convenient to equipment Technical Field The utility model belongs to the technical field of PE pipes, and particularly relates to a PE pipe convenient to assemble. Background PE pipe (polyethylene plastic pipe) is widely applied to the fields of building water supply and drainage, municipal gas transportation, agricultural irrigation, industrial fluid transportation and the like due to the characteristics of corrosion resistance, high pressure resistance, low cost and the like. Along with the development of urban construction and infrastructure engineering, the installation requirement of PE pipes is increased, and the convenience and reliability of the connection mode directly influence the engineering efficiency and the system stability. When the conventional PE pipes are connected, the conventional PE pipes are generally connected by direct hot-melt connection or hot-melt flange (after the flange is welded, the flange is fixed by bolts), however, when the conventional PE pipes are actually used, the following defects exist: Firstly, adopting a direct hot-melting connection or a connection mode of a hot-melting flange plate, needing a special hot-melting machine or an electric-melting welding machine, having high equipment cost and high technical threshold, enabling operators to master welding parameters, enabling new operators to easily cause excessive melting or virtual connection of pipes due to improper temperature control, and secondly, adopting a direct hot-melting connection or a connection mode of a hot-melting flange plate, fixing the angle of a pipeline, and additionally using prefabricated elbows of 90 DEG, 45 DEG and the like when meeting obstacles such as corners, beams and the like. Therefore, it is necessary to provide a PE tube that is easy to assemble. Disclosure of utility model Aiming at the problems, the utility model provides a PE pipe convenient to assemble, and the technical scheme is as follows: The PE pipe comprises a first pipe body, a second pipe body, joints, corrugated pipes, positioning columns, positioning grooves and positioning frames, wherein the inner structure shapes of the first pipe body and the second pipe body are identical, the joints are slidably arranged at one ends of the first pipe body and the second pipe body, the corrugated pipes are fixed between the joints, the positioning grooves are formed in the first pipe body and the second pipe body along straight lines, the positioning columns are fixedly arranged on the joints through threaded engagement, one ends of the positioning columns are slidably arranged in the corresponding positioning grooves, and the positioning frames are rotatably arranged between the joints.
