Description

Technical Field

[0001] The utility model relates to the technical field of continuously wound glass fiber reinforced plastic pipes, in particular to a continuously wound glass fiber reinforced plastic pipe with improved impact resistance. Background Art

[0002] The outer wall toughness of the FRP pipe in the prior art is poor. It is easy to deform or break after being impacted by external objects during installation or use, thereby reducing the service life of the FRP pipe. In addition, the connection method between FRP pipes mostly adopts a connecting sleeve, and the pipe body is inserted into the sleeve for connection. When connecting, both connected FRP pipes need to be plugged into the connecting sleeve in a plug-in manner, and a sealing rubber ring with a limiting structure needs to be installed on the connecting sleeve to limit the position of the two FRP pipes to be connected and to seal between the FRP pipe and the connecting sleeve; or a stainless steel sleeve is fixed at both ends of the two FRP pipes to be connected, and then the stainless steel sleeves on the two FRP pipes are welded and connected by welding equipment, thereby connecting the two FRP pipes. This method increases the assembly time of the FRP pipe and requires professional welders to weld, thereby reducing the installation efficiency and increasing the connection cost between pipes. To this end, a continuously wound FRP pipe with improved impact resistance is proposed to facilitate the connection of FRP pipes and improve the assembly efficiency of FRP pipes.
