Project Overview

QTech-Machinery supplied a complete Φ20–Φ110 mm HDPE pipe extrusion line for a customer producing PE water supply pipes. The project was designed for HDPE material, PE100 grade raw material, black pipe production, and four color stripe marking.

As a professional HDPE pipe extrusion line manufacturer in China, QTech-Machinery configured this production line according to the customer’s pipe diameter range, required output, workshop layout, automation level, and long-term production needs.

This HDPE pipe production line covers the full process from raw material handling to finished pipe collection, including automatic loading, drying, extrusion, gravimetric metering, color stripe co-extrusion, pipe moulding, vacuum calibration, spray cooling, servo haul-off, cutting, winding, stacking, and spare parts support.

The line is suitable for manufacturing small and medium diameter HDPE pipes used in water supply, irrigation, municipal pipeline systems, and general fluid transportation.

02 / What We Solved

Requirement And Solution

What the customer needed to produce, and the line we configured to get there.

Φ20–Φ110 mm HDPE Pipe Extrusion Line Project by QTech-Machinery
Requirement

What The Customer Needed

The customer needed a reliable HDPE pipe extrusion line manufacturer in China to provide a complete production system for Φ20–Φ110 mm HDPE pipe manufacturing. The main objective was to build a stable and efficient extrusion line for PE water supply pipe production.

The production line needed to support multiple pipe diameters, including 20 mm, 25 mm, 32 mm, 40 mm, 50 mm, 63 mm, 75 mm, 90 mm, and 110 mm. It also needed to meet different SDR production requirements and maintain stable pipe wall thickness during continuous production.

The customer also required flexible finished pipe handling. Smaller pipe sizes needed to be collected by winder, while larger or straight pipe products needed to be discharged by stacker. Therefore, QTech-Machinery included both pipe winding units and a discharge rack in the final solution.

Solution

What We Supplied

QTech-Machinery designed a complete HDPE pipe extrusion line solution based on the required pipe range, output, material type, and factory operating conditions.

The line used an SJ75/33 single-screw extruder as the main extrusion machine. This extruder provides 200–250 kg/h output and is suitable for continuous HDPE pipe production. It is equipped with Siemens PLC control, MCGS touchscreen HMI, ABB inverter, Siemens motor, and a high-torque gearbox.

To improve raw material control and pipe accuracy, QTech-Machinery included a double-layer gravimetric metering system. This system helps control material feeding, pipe meter weight, and wall thickness stability.

For pipe appearance and product identification, the line included an SJ25/25 color-stripe co-extruder. This unit allows the customer to produce black HDPE water pipes with four color stripes.

The pipe forming section used a Φ20–Φ110 mm high-speed PE pipe die with 40Cr forged steel, copper sizing sleeves, water-jacket cooling, and precision spiral melt distribution.

For sizing and cooling, QTech-Machinery configured one 9 m vacuum calibration tank and two 6 m spray cooling tanks. This structure provides sufficient cooling length for different pipe sizes and wall thicknesses.

The downstream section included a three-caterpillar servo haul-off unit, a fly-knife cutter plus ring-type chipless cutter, a 20–63 mm double-station pipe winder, a 75–110 mm single-station pipe winder, and a 5 m discharge and stacking rack.
