Product Description

Product Overview

Qingdao Huashida's large-diameter HDPE hollow-wall winding pipe production line is one of China's earliest systems of its kind, backed by extensive technical expertise and proven experience in installation, commissioning, and operation. It produces HDPE hollow-wall winding pipes and antistatic gas-extraction pipes for mining applications, with diameters ranging from 300 to 1200 mm.

Featuring an I-beam-shaped hollow-wall structure, the pipes combine high structural strength with lightweight flexibility. Compatible with specialized fittings such as electrofusion belts and heat-shrink sleeves, the system enables convenient installation, reliable connections, and cost-effective construction. These pipes are widely used in municipal sewerage and drainage systems as an effective alternative to traditional concrete and cast-iron pipes.

Extruder

The system uses a PE/PP single-screw extruder. The feeding section of the extrusion unit is equipped with forced water cooling and a grooved barrel, significantly reducing the power consumption of the main drive motor. The extruder features a large L/D ratio screw (30–38:1), offering strong material adaptability and excellent plasticizing performance. For customers using recycled materials or adding calcium carbonate, specially designed screws can be customized upon request.

Spiral Forming Machine

Equipped with a composite die head, the machine forms pipes through spiral rotation. With a compact structure and unique design, it ensures high-quality products.

Forming Machine

High-quality workmanship and compact design with stable transmission.

Control System

Professional PLC control system with intelligent centralized operation.
