The invention belongs to the field of PE (polyethylene) pipe production, and particularly relates to a high-heat-resistance modified PE pipe production process which comprises the following steps: S1, establishing a perfect raw material detection and control system, formulating a detailed raw material quality standard, screening raw materials of PE pipes, removing the raw materials which do not meet the standard, and strengthening storage and transportation management of the raw materials; the raw materials are prevented from being polluted or damaged, purchase and delivery of the raw materials are strictly managed and recorded, and the traceability of the raw materials is guaranteed. Raw materials can be more uniformly mixed and dried, the plasticizing and extruding efficiency of the raw materials is improved, the heat resistance and mechanical performance of the pipe are improved, the shape and size of the pipe can be more accurately controlled by accurately controlling parameters such as the temperature, t
