Description

Technical Field

[0001] The utility model relates to the technical field of pipeline welding, in particular to a PE pipe hot-melt butt welding machine. Background Art

[0002] PE pipe refers to polyethylene pipe, which has a wide range of applications, from small-section yellow pipes for natural gas to thick-walled black pipes for industrial and urban pipelines. Large-diameter hollow wall pipes are rapidly growing as substitutes for concrete rainwater drain pipes and other sewer pipelines. They have excellent resistance to most domestic and industrial chemicals. When PE pipes are connected, they are connected by hot-melt welding.

[0003] When hot-melt welding is performed on existing PE pipes, the PE pipes are placed on a butt welding frame and fixed before hot-melting. However, when the existing butt welding frame is used, a large amount of harmful smoke will be generated during the hot-melt process of the PE pipes. When the operators inhale it, it will cause damage to their health. Therefore, we propose a PE pipe hot-melt butt welding machine to solve the above problem. Utility Model Content
