Description

Technical Field

[0001] The utility model relates to the field of steel skeleton composite pipes, in particular to a connecting structure of a movable steel skeleton composite pipe. Background Technique

[0002] As a new type of pipeline, the steel skeleton composite pipe uses high-strength over-plastic steel wire mesh skeleton and other materials as raw materials. The steel wire winding mesh is used as the skeleton reinforcement of other materials. High-performance modified bonding resin is used to tightly connect the steel wire skeleton with the inner and outer layer of other materials, so that it has excellent composite effect. Because the high-strength steel wire reinforcement is coated in other materials, this composite pipe overcomes the respective disadvantages of steel pipes and materials, while maintaining the respective advantages of steel pipes and materials. The steel wire mesh skeleton composite pipe uses high-quality materials and advanced production processes, so that it has higher pressure resistance. At the same time, the composite pipe has excellent flexibility and is suitable for long-distance buried water supply and gas transmission pipeline systems.

[0003] However, the currently used steerable anti-collision protection device is an integral structure, and only simple welding is carried out at the connection. When damage occurs, the entire pipeline needs to be overhauled, which increases the labor and time costs and is extremely inconvenient to use.
