1. Overview of Large Diameter PE Agricultural Water Pipe Extrusion Equipment
1.1 Industry Demand and Production Characteristics of Agricultural Large-Diameter PE Pipes
Agricultural water conservancy projects have extremely strict practical application requirements for large-diameter PE water pipes. Different from municipal pipes that focus on appearance precision, agricultural PE pipes pay more attention to pressure resistance, anti-aging performance, buried corrosion resistance, and low-cost mass production performance. Large-diameter PE irrigation pipes undertake the main water delivery tasks of large-area farmland irrigation, drought resistance water supply, and regional water resource deployment, and need to adapt to complex outdoor environments such as high temperature, low temperature, humid soil, and microbial corrosion for a long time.
In terms of production characteristics, large-diameter PE pipes have large melt output per unit time, high requirement for melt uniformity, and strict control standards for wall thickness deviation and pipe roundness. Ordinary general-purpose extrusion machines are prone to problems such as unstable melt pressure, uneven wall thickness, pipe oval deformation, and insufficient internal material density when producing large-diameter pipes, resulting in substandard pipe pressure resistance and easy water leakage and cracking in the later stage of engineering use. Professional customized large-diameter PE pipe extrusion equipment is the basic guarantee for producing qualified agricultural water pipes.
With the global investment increase in agricultural water-saving projects and rural water conservancy transformation, the market demand for large-diameter PE agricultural water pipes continues to grow, and the market has higher and higher requirements for pipe production efficiency and quality stability, which promotes the continuous upgrading and optimization of professional PE pipe extrusion production lines.

1.3 Composition of Complete Large-Diameter PE Pipe Extrusion Line
A complete set of FAYGO large diameter PE agricultural water pipe extrusion production line is composed of multiple core supporting equipment, forming an integrated automatic production process from raw material feeding to finished pipe cutting and discharging. The whole line includes quantitative feeding system, professional PE screw extrusion host, large-diameter pipe extrusion mold, multi-stage vacuum shaping cooling system, high-power synchronous traction machine, automatic fixed-length cutting machine, and finished pipe turnover rack.
Each supporting equipment is matched according to the production characteristics of large-diameter agricultural PE pipes. The multi-stage vacuum shaping system solves the oval deformation problem of large-diameter pipes, the high-power traction machine ensures stable low-speed traction of super-large pipes, and the automatic cutting system realizes flat and burr-free cutting of thick-walled large-diameter pipes. The whole line realizes full-automatic continuous production, effectively improving production efficiency and product consistency of agricultural water pipes.
2. Core Structural Design and Working Principle
2.1 Special Screw and Barrel Structure for Large-Diameter PE Extrusion
The screw and barrel are the core components that determine the extrusion quality of large-diameter PE pipes. FAYGO adopts a special PE high-efficiency screw design with a length-diameter ratio of 32:1, which is specially optimized for HDPE agricultural pipe raw materials. Compared with ordinary screw structures, this design has stronger material conveying capacity, more uniform shear plasticization effect, and can realize full melting and homogenization of high-density PE raw materials without dead angles.
The screw adopts a segmented gradual compression structure, which can avoid excessive shear heat generation during large-output extrusion, prevent PE material decomposition and aging, and ensure that the melt maintains stable fluidity and uniformity. The barrel is made of high-strength wear-resistant alloy steel with an optimized water-cooling jacket structure, which can realize rapid and uniform temperature adjustment, effectively control the melt temperature difference, and avoid local overheating leading to pipe surface defects and internal performance degradation.
This professional structural design ensures that during the production of 200mm to 800mm large-diameter pipes, the melt output is stable, the material density is uniform, and the residual internal stress of the pipe is low, which greatly improves the outdoor anti-aging and anti-cracking performance of agricultural water pipes.
2.2 High-Stability Melt Pressure Control System
Melt pressure fluctuation is the main cause of uneven wall thickness and oval deformation of large-diameter PE pipes. FAYGO large diameter PE extrusion machine is equipped with a high-precision real-time melt pressure monitoring and closed-loop adjustment system. The high-sensitivity pressure sensor installed at the machine head can collect melt pressure data in real time, and the intelligent control system automatically adjusts the screw speed and feeding volume to keep the melt pressure stable within the standard range of 18-24MPa.
For large-diameter pipes with large extrusion cross-sectional area, stable melt pressure can ensure uniform material output at each position of the mold, effectively controlling the pipe wall thickness deviation within ±0.1mm, far exceeding the industry ordinary standard. The stable pressure output also avoids intermittent material supply, ensures continuous and smooth pipe molding, and reduces the defective rate caused by pressure fluctuation.
2.3 Multi-Stage Vacuum Shaping and Cooling System Principle
Large-diameter PE pipes are prone to deformation and irregular roundness after extrusion due to their large caliber and heavy pipe body. FAYGO complete extrusion line is equipped with a multi-stage vacuum shaping box and circulating water cooling system specially for large-diameter pipes. The segmented adjustable vacuum structure realizes uniform negative pressure shaping of the pipe outer wall, ensuring perfect roundness of the pipe body.
The circulating water film cooling technology adopts uniform water distribution and low-temperature circulating water supply, which realizes slow and uniform cooling of large-diameter thick-walled pipes, avoids internal stress concentration caused by rapid cooling, and improves the overall structural stability and pressure resistance of the pipe. The multi-stage cooling design ensures that the large-diameter pipe is fully shaped and cooled before traction, preventing pipe deformation and size deviation during traction and transmission.
2.4 Synchronous Traction and Fixed-Length Cutting System
The large-diameter PE agricultural water pipe has a heavy single pipe body, which requires high traction stability and synchronization. FAYGO supporting high-power crawler traction machine adopts multi-group crawler synchronous driving design, with large contact area and strong clamping force, which can stably traction super-large-diameter pipes without sliding and deviation. The stepless speed regulation function realizes low-speed stable production matching of large-diameter pipes, ensuring the consistency of pipe size and wall thickness.
The automatic fixed-length cutting system is equipped with a high-precision positioning sensor, which can realize fixed-length cutting according to engineering standard requirements. The planetary cutting tool adopts high-speed flat cutting technology, with flat cutting section and no burrs, which does not affect the later pipe docking and engineering laying quality. The whole process realizes automatic linkage with extrusion and traction, improving the continuity and automation of production.
3. Key Technical Advantages for Agricultural Water Pipe Production
3.1 Excellent Low-Temperature and Weather Resistance Pipe Molding Effect
Agricultural water pipes need to be laid outdoors for a long time, facing extreme weather such as low temperature freezing in winter and high temperature exposure in summer. FAYGO professional large-diameter PE extrusion machine can fully homogenize PE raw materials and functional additives in the extrusion process, ensuring uniform dispersion of anti-ultraviolet and anti-aging components inside the pipe material. The produced large-diameter PE pipes have excellent low-temperature toughness and weather resistance, which can avoid brittle cracking in low-temperature environment and aging and fading in long-term sun exposure.
Different from ordinary extrusion equipment that has insufficient material mixing and uneven additive distribution, FAYGO equipment’s precise plasticization and mixing technology ensures that every section of the pipe has consistent performance, meeting the long-term outdoor service life requirements of agricultural water conservancy projects, and reducing the later maintenance and replacement cost of engineering pipelines.
