The reinforced non-metallic joint is a special non-metal joint designed for the bonded continuous composite pipe. The welding equipment used is similar to that of ordinary polyethylene pipes. When the joint is installed, the inner pipe of the composite pipe is first butt-welded by hot-melt welding. After the welding quality is intact, the special reinforced electrofusion sleeve is moved to the welding position, and then the reinforced sleeve is energized and welded (the connecting sleeve can bear the axial load), so as to Greatly improve the hoop strength and axial strength of the welded part of the composite pipe. The non-metallic joint has passed the blasting test and 165-hour hydrostatic pressure test of PetroChina Xi'an Pipe Institute, and can achieve the same strength as the pipe body. The breakthrough of this joint technology not only completely solves the corrosion problem of metal joints, but also greatly reduces the production cost of large-diameter composite pipes.
