Description

Technical Field

[0002] FRP pipe is a lightweight, high-strength, corrosion-resistant non-metallic pipe. It is mainly composed of resin-based glass fibers wound layer by layer on a rotating core mold according to process requirements, and quartz sand is laid between the fibers as a sand layer.

[0003] In order to continuously splice FRP pipes, the two ends of the pipes are generally made into a male head and a female head respectively. During installation, the male head of one pipe is inserted into the female head of another pipe during splicing; in order to ensure the sealing of the splicing position, the inner wall of the female head is made into a long cylindrical rubber ring; the rubber ring is relatively long, and to be firmly integrated with the pipe body, it is necessary to set a plurality of grooves on the outer wall of the rubber ring so that the material of the pipe body can fit into the groove; when the pipe body is produced, it is generally wound with multiple layers of glass fiber and mixed with resin and quartz sand. The traditional production method of producing FRP pipes generally only has resin and a small amount of glass fiber entering the groove of the rubber ring, which affects the bonding strength between the rubber ring and the pipe body; when the glass fiber is manually wound into the groove, the worker needs to use his hands to grasp the winding direction.
