HDPE (high-density polyethylene) pipes are widely used in water supply and drainage, petrochemical, agricultural irrigation and other fields due to their corrosion resistance, impact resistance, environmental friendliness and other advantages. As core production equipment, HDPE Pipe Extrusion Lines have high market transaction activity, especially used equipment, which is favored by small and medium-sized enterprises for its cost-effectiveness. This article will analyze the price range of used HDPE Pipe Extrusion Lines from the perspective of equipment types, and compare it with the price of new equipment to provide reference for industry procurement decisions.
I. Classification and Price Range of Used HDPE Pipe Extrusion Lines
Combined with industry practices and market application scenarios, used HDPE Pipe Extrusion Lines can be mainly divided into three dimensions: production line scale, technical level, and application field. Due to differences in production capacity, configuration, and usage wear and tear, there are significant differences in price ranges among different types of equipment. The following price data are compiled based on quotations from major global trading platforms (such as Alibaba, MIC), all denominated in US dollars. The actual transaction price may be affected by factors such as equipment service life, maintenance status, brand, and supply-demand relationship.
(I) Classification by Production Line Scale
Small-sized HDPE Pipe Extrusion Lines: Mainly suitable for small enterprises, family workshops or laboratory research and development, with a production capacity usually below 100kg/h. They can be further subdivided according to the producible pipe diameter: 16-63mm small-diameter models are suitable for fine pipe production, with a used price of 12,000 – 16,000 US dollars; 63-110mm conventional small-diameter models are mainly equipped with single-screw extruders and have low automation levels, with a used market price roughly in the range of 16,000 – 20,000 US dollars. Specifically, the market quotations for used small-sized production lines of 20-110mm specifications are mostly concentrated in the range of 15,000 – 18,000 US dollars; the price of near-new equipment with a service life of 1-3 years is about 18,000 – 20,000 US dollars, close to 60% of the price of new equipment; the price of equipment with a service life of more than 5 years and general maintenance can be as low as 12,000 US dollars, and some simple small-diameter equipment for agricultural irrigation can even be as low as about 10,000 US dollars.
Medium-sized HDPE Pipe Extrusion Lines: Suitable for small and medium-sized enterprises and municipal sporadic projects, with a production capacity of 100-500kg/h. They can be subdivided into three grades according to the pipe diameter range: 110-250mm general-purpose models, mostly equipped with single-screw extruders and basic PLC control systems, with a used price of 30,000 – 45,000 US dollars; 250-400mm medium-large diameter models, which need to be equipped with enhanced screws and cooling systems, with a used price of 45,000 – 55,000 US dollars; 400-630mm large-diameter basic models, mostly equipped with twin-screw extruders, with a used price of 55,000 – 60,000 US dollars. The overall used price range of such equipment is 25,000 – 60,000 US dollars. Among them, equipment with a service life of 3-5 years and good maintenance accounts for the highest proportion, with prices concentrated in the range of 35,000 – 50,000 US dollars, and the price of equipment with a service life of more than 5 years is mostly 25,000 – 35,000 US dollars.
Large-sized HDPE Pipe Extrusion Lines: Mainly used in large enterprises and key projects (such as urban main pipelines, petrochemical long-distance pipelines), with a production capacity of more than 500kg/h. They can be divided into 630-1000mm conventional large-diameter and above 1000mm extra-large diameter according to the pipe diameter. 630-1000mm conventional large-sized production lines are equipped with twin-screw extruders, fully automatic control systems and basic testing equipment, with a used price of 350,000 – 600,000 US dollars; high-end models with imported technologies from Germany, the United States, etc., have strong stability of core components, so their used price is 600,000 – 1,000,000 US dollars; equipment with extra-large diameter above 1000mm or special working conditions (such as high-pressure oil transportation) needs to be equipped with high-precision forming molds and intelligent monitoring systems, and the used price can reach 3.5 million – 4.38 million US dollars. Such equipment has a small circulation in the market, and the price is significantly affected by the supply-demand relationship.
(II) Classification by Technical Level
Traditional Used HDPE Pipe Extrusion Lines: Mainly manually operated, with low automation level, no intelligent monitoring and feedback system, and relying on the operator’s experience to control process parameters. The prices are subdivided by scale as follows: small-sized traditional equipment (16-110mm) is 12,000 – 18,000 US dollars, among which 16-63mm small-diameter models are 12,000 – 15,000 US dollars, and 63-110mm models are 15,000 – 18,000 US dollars; medium-sized traditional equipment (110-630mm) is 25,000 – 40,000 US dollars, 110-250mm models are 25,000 – 32,000 US dollars, and 250-630mm models are 32,000 – 40,000 US dollars; large-sized traditional equipment (above 630mm) is 350,000 – 500,000 US dollars. Its core advantage is low procurement cost, suitable for small and micro enterprises or simple pipe production scenarios with low requirements on production efficiency and product precision.
Intelligent Used HDPE Pipe Extrusion Lines: Adopt advanced automation technology and PLC full-control system, which can realize automatic adjustment of production parameters, online monitoring of product quality, fault early warning and other functions. The production efficiency is more than 30% higher than that of traditional equipment, and the product qualification rate is higher. Prices subdivided by scale: small-sized intelligent equipment (16-110mm) is 20,000 – 30,000 US dollars, 16-63mm models are 20,000 – 25,000 US dollars, and 63-110mm models are 25,000 – 30,000 US dollars; medium-sized intelligent equipment (110-630mm) is 45,000 – 60,000 US dollars, 110-250mm models are 45,000 – 50,000 US dollars, and 250-630mm models are 50,000 – 60,000 US dollars; large-sized intelligent equipment (above 630mm) is 600,000 – 1,000,000 US dollars. Among them, Chinese-made intelligent used equipment has a cost advantage, with a price 10%-15% lower than that of imported intelligent used equipment of the same specification. For example, the price of Chinese-made intelligent used equipment of 250-630mm medium-sized is 50,000 – 55,000 US dollars, while the imported model of the same specification needs 58,000 – 65,000 US dollars.
(III) Classification by Application Field
Used HDPE Pipe Extrusion Lines for Water Supply and Drainage: With the largest market demand and moderate technical threshold, the prices are subdivided by pipe diameter: small-sized (16-110mm) is 12,000 – 20,000 US dollars, suitable for community branch pipe laying; medium-sized (110-630mm) is 30,000 – 50,000 US dollars, among which 110-250mm models are 30,000 – 40,000 US dollars (suitable for municipal branch pipes), and 250-630mm models are 40,000 – 50,000 US dollars (suitable for municipal main pipes); large-sized (above 630mm) is 350,000 – 800,000 US dollars, 630-1000mm models are 350,000 – 550,000 US dollars, and above 1000mm models are 550,000 – 800,000 US dollars. Such equipment is the most widely circulated type in the used market, accounting for more than 60% of the total transaction volume of used HDPE pipe extrusion lines.
Used HDPE Pipe Extrusion Lines for Petrochemical Industry: Due to the need to adapt to high-pressure and corrosion-resistant working conditions, the equipment material (mostly stainless steel screws and barrels) and process requirements are higher, and the price is significantly higher than that of equipment for water supply and drainage. The price of medium-sized equipment (110-630mm) is 50,000 – 80,000 US dollars, 110-250mm models are 50,000 – 65,000 US dollars, and 250-630mm models are 65,000 – 80,000 US dollars; the price of large-sized equipment (above 630mm) is 800,000 – 1.2 million US dollars, 630-1000mm models are 800,000 – 1 million US dollars, and extra-large models above 1000mm are 1 million – 1.2 million US dollars. Such equipment has strict requirements on the wear of core components, and near-new equipment (with a service life of 1-3 years) accounts for more than 70%.
Used HDPE Pipe Extrusion Lines for Agricultural Irrigation: Most of them are small or medium-sized general-purpose equipment with low precision requirements. Some models can simplify the cooling or testing system, and the price is relatively affordable. Small-sized equipment (16-110mm) is 12,000 – 18,000 US dollars, 16-63mm small-diameter drip irrigation pipe special models are 12,000 – 15,000 US dollars, and 63-110mm field irrigation pipe models are 15,000 – 18,000 US dollars; medium-sized equipment (110-250mm) is 25,000 – 40,000 US dollars; the used price of some simple small-sized equipment (without complex control system) can be as low as about 10,000 US dollars, which is the lowest-priced category among all types.
II. Price Comparison between Used and New HDPE Pipe Extrusion Lines
The core competitiveness of used HDPE Pipe Extrusion Lines lies in their price advantage. Their price is usually 30%-60% of that of new equipment of the same specification. The specific discount ratio is affected by the equipment’s service life, brand, and maintenance status: the price of near-new equipment with a service life of 1-3 years is 50%-60% of that of new equipment; the price of equipment with a service life of 3-5 years is 40%-50% of that of new equipment; the price of equipment with a service life of more than 5 years is mostly 30%-40% of that of new equipment. To more intuitively present the price difference, the following is a comparison table of used and new equipment prices of different types (unit: ten thousand US dollars):
| Equipment Type | Specific Specification | Price of New Chinese-made Equipment | Price of New Imported Equipment | Price of Used Chinese-made Equipment (3-5 years of use) | Price of Used Imported Equipment (3-5 years of use) | Cost Savings Ratio of Chinese-made Equipment | Cost Savings Ratio of Imported Equipment |
| Small-sized | 16-63mm | 2.8-3.5 | 3.8-4.5 | 1.2-1.5 | 1.5-1.8 | 46%-61% | 47%-67% |
| Small-sized | 63-110mm | 3.5-5 | 4.5-6 | 1.5-2 | 1.8-2.4 | 43%-60% | 44%-60% |
| Medium-sized | 110-250mm | 6-8 | 8-10 | 3-4 | 3.8-5 | 44%-55% | 45%-55% |
| Medium-sized | 250-630mm | 8-12 | 10-15 | 4-6 | 5-7.5 | 45%-55% | 45%-57% |
| Large-sized | 630-1000mm | 80-120 | 120-180 | 35-60 | 60-90 | 45%-54% | 44%-50% |
| Large-sized | Above 1000mm | 180-250 | 300-500 | 90-130 | 150-250 | 47%-48% | 45%-50% |
| Intelligent Medium-sized | 110-630mm | 8-12 | 12-16 | 4.5-6 | 6-8.5 | 46%-54% | 46%-56% |
Supplementary explanation from the brand perspective: The price of new Chinese-made equipment is 20%-30% lower than that of imported new equipment of the same specification, so Chinese-made used equipment has a more obvious price advantage. Taking medium-sized intelligent equipment (110-630mm) as an example, the price of new Chinese-made intelligent equipment is 80,000 – 120,000 US dollars, and the used price is 45,000 – 60,000 US dollars; while the price of imported new intelligent equipment of the same specification is 120,000 – 160,000 US dollars, and the used price is 60,000 – 85,000 US dollars. Chinese-made used equipment saves an additional 15%-20% of the cost compared with imported used equipment. In addition, the price difference of equipment in special application fields is also significant. For example, for medium-sized 250-630mm equipment for petrochemical industry, the price of new Chinese-made equipment is 100,000 – 140,000 US dollars, and the used price is 55,000 – 70,000 US dollars; the price of imported new equipment is 150,000 – 200,000 US dollars, and the used price is 80,000 – 110,000 US dollars. The cost savings ratio is basically the same as that of general-purpose equipment, but the overall price base is higher.

III. Key Factors Affecting the Price of Used HDPE Pipe Extrusion Lines
In addition to equipment type and specification, there are three key factors that significantly affect the used price: first, service life and maintenance status. The shorter the service life, the complete the maintenance records, and the less wear of core components (such as screws and barrels), the higher the price. Near-new equipment (with a service life of 1-3 years) can even reach 60% of the price of new equipment. For example, the used price of small-sized 63-110mm Chinese-made equipment with a service life of 1-3 years can reach 22,000 – 25,000 US dollars, close to 50%-60% of the price of new equipment; if the core components are severely worn, the price may be reduced by another 20%-30%. Second, brand. Used equipment of imported brands (such as German KraussMaffei, American Davis-Standard) has a good quality reputation, so its price is 10%-15% higher than that of Chinese-made used equipment of the same specification, and some high-end models are even 20% higher. Third, market supply and demand. When the construction and municipal engineering industries are in the peak demand season or the production capacity of new equipment is insufficient, the price of used equipment will rise by 5%-10%, and vice versa, it will decrease slightly. For example, in the peak season of agricultural irrigation (spring), the price of small-sized agricultural equipment will be 5%-8% higher than that in the off-season.
IV. Conclusion
The price of used HDPE Pipe Extrusion Lines covers the range of 10,000 – 4.38 million US dollars. There are significant price differences among equipment of different scales, technical levels and application fields. Among them, the price of simple small-sized equipment for agricultural irrigation is the lowest (about 10,000 US dollars), and the price of extra-large diameter intelligent equipment for large-scale petrochemical industry is the highest (up to 3.5 million – 4.38 million US dollars). Compared with new equipment, used equipment can generally save 40%-60% of the procurement cost. Among them, Chinese-made used equipment has a more prominent cost-effectiveness advantage due to its lower basic price, which is especially suitable for small and medium-sized enterprises, start-ups or short-term engineering projects with limited budgets. When purchasing, buyers need to combine their own production capacity needs (such as hourly output, pipe diameter) and application scenarios (such as water supply and drainage, petrochemical industry, agricultural irrigation), focus on the equipment’s service life, maintenance status and brand reputation, and refer to changes in market supply and demand. Priority should be given to near-new equipment with complete maintenance records to achieve a balance between cost and efficiency; if used in special working conditions (such as high pressure and corrosion resistance), it is necessary to focus on the equipment’s material and core component performance to avoid affecting production efficiency due to equipment wear and tear.
