The invention relates to a pipe end flange head winding molding process and equipment for plastic or composite pipes, and belongs to the field of pipe end improved technologies for composite pipes. According to the process, flange heads are directly molded at the pipe ends of the composite pipes by winding extruded strip materials, and pure plastic ends are reserved so as to realize hot-melt butting; or steel flanges are prefabricated at the backs of plastic flanges, and the flanges are connected through bolts so as to realize the connection of a whole pipeline system. The process comprises the main molding steps of: heating the external surface of plastics of the end face of one pipe end to the temperature of 170-180 DEG C, extruding plastics in a winding strip manner by using a strip material extruder, extending a pipe internal-staying mechanism inside a pipe, slowly rotating the pipe in a manner of being cooperated with a motor structure, winding a heated strip to the pipe end in a winding mold, compressing the strip on the pipe by using a pressing wheel, stopping winding until a specified flange head size is wound, putting the flanges in the flange heads, and winding the other end. The wound flange heads are simple in operation and good in pressure bearing capacity, the cost is reduced, the sealing performance is improved, and the connection is simple, convenient, safe and reliable.
