Assembly type plastic pressure pipe, production die, production method as well as plastic plate and pipe gallery

Abstract

The invention relates to an assembly type plastic pressure pipe, a production die, a production method as well as a plastic plate and a pipe gallery. The assembly type plastic pressure pipe comprisesa plurality of pipe pieces, all the pipe pieces can be sequentially spliced to form a plastic pressure pipe body, the two adjacent pipe pieces are subjected to hot-melt welding, and electric heating wires are arranged in the joints. According to the assembly type plastic pressure pipe, the plurality of pipe pieces are subjected to hot-melt welding to form the whole pipe, and compared with an existing extrusion forming of the whole pipe, each pipe piece is independently machined and manufactured, so that manufacturing difficulty is low, equipment investment is small, energy consumption is low,the cost is low, the rate of finished products is high, and efficiency is high; then the plurality of pipe pieces are subjected to hot-melt welding so that one large-caliber plastic pressure pipe canbe manufactured, and the problem that the large-caliber plastic pressure pipe is difficult to manufacture by an existing extrusion forming method is solved; and a lot of problems about whole pipe extrusion forming of the large-diameter pressure pipe are solved, and the characteristics of being uniform in wall thickness, good in coaxiality, high in pressure resistance, high in ring stiffness and high in yield are achieved.

Description

technical field [0001] The invention relates to the field of pipe manufacturing, in particular to an assembled plastic pressure pipe, a production mold, a production method, a plastic plate and a pipe gallery. Background technique [0002] Existing plastic pressure pipes are generally produced by extrusion molding. At present, the maximum diameter of plastic pressure pipes produced is 2m. If extrusion molding is used to produce plastic pressure pipes with large diameters (diameter greater than 2m), it is easy to produce pressure pipes with a wall thickness of up to Failure to meet the requirements, eccentricity, poor coaxiality, bubbles and other defects lead to poor quality and low yield. Since the extrusion molding method is integral molding, the production mold size of large-diameter plastic pressure pipes is large, which affects the performance of the equipment. High requirements, expensive equipment, high energy consumption, low yield, difficult operation and high cost....
