The utility model belongs to a technology for producing prestress high concrete (PHC) pipe piles, and relates to a production stream line for conveying PHC pipe piles. The production stream line is characterized by comprising a whole workshop which is formed by a left area, a middle area and a right area, from the front to the back of the workshop, the workshop in the left area sequentially provided with a blending building, an end plate processing area, a steel reinforcement cage and end plate assembly area and a steel reinforcement cage roll welding area; the workshop in the middle area is sequentially provided with a concrete spreading area, a caging area, an oil injection tank, a mold cleaning tank, a mold removing area and a steel bar fine cutting and heading area; and the workshop in the right area is sequentially provided with a stretching area, a centrifugal molding area, a steam curing area, a pipe pile stretching area, a product inspecting and sprayed code marking area, an area for storing semi-finished pipe piles to be steam-cured at high pressure and an inlet autoclave transition carriage pit. The production stream line has the beneficial effects that planar circulation arrangement is adopted, and the accident occurrence rate is reduced through an up and down inter-moving stereoscopic lifting technological mode; and an inclined platform and an inclined track are adopted to move the pipe piles, so that the moving distance of a travelling crane is greatly shortened, and the energy consumption is reduced.
