Some PE pipes are produced by blow molding process, especially small and medium-sized PE pipes. The blow molding process squeezes the molten polyethylene raw material into a tubular blank, and then expands it with the help of compressed air and fits the inner wall of the mold. After cooling, a pipe with a certain wall thickness is formed, which is suitable for the production of PE pipes with relatively simple structures. The large-diameter PE pipes or enhanced PE pipes are more extruded by extrusion molding process, and the raw materials are continuously extruded into tubes through a screw extruder, which can better control the uniformity of wall thickness and structural strength.

Wuhan's Hubei AD Building Materials Co., Ltd. as a professional PE pipe manufacturer, flexibly adopts blow molding or extrusion process according to the pipe specifications, providing multi-specification PE pipe wholesale, and can customize products of different diameters. The company is familiar with the application scenarios of various processes, and can choose the appropriate process according to the customer's specifications and performance requirements for PE pipes to ensure stable product quality.
