The price of pe as a common construction material in areas such as municipal works, drainage and agricultural irrigation has always been one of the central concerns of industry practitioners and buyers. A number of practitioners have recently asked about future trends in pe prices of one metre and whether there are differences in prices under different quality classes. In combination with industry realities and market patterns, we can decipher these problems from multiple dimensions and shed light on the bottom logic of pe prices and the idea of buying。
First, it should be clear that the price of the pe tube is not a single fixed value and that different quality grades, feedstock standards and specification calibres directly affect the final unit price. The pe tubes in the current market are divided into new and recycled materials based on raw materials. The pe tubes produced by the new materials meet national standards of gb/t13663. 2-2018, are all polyethylene resin particles, do not add heavy metal stabilizers, and have been certified for sanitary safety in drinking water distribution equipment. The prices of such tubes generally range from 10 to 100 yuan per metre to increase with the increase in the length of the pipes, for example, the total new materials of 20 pe for water pipes with a price of about 15 yuan per metre, while the large calorie content of dn600 may exceed 300 yuan per metre. If a pe tube is produced using recycled materials, in order to control the cost of mixing a percentage of recycled plastics, there may be a negative public gap in the thickness of such pipes, no national standards are available for carrying capacity and useful life, and prices tend to be around 30 per cent lower per metre than for fresh materials, but subsequent problems such as detonators, leaks and other problems increase the cost of later maintenance。
In terms of long-term trends in the industry, changes in the price of a metre of pe management are mainly influenced by three factors. The first is the volatility of upstream feedstock prices, where the price of polyethylene resin, as the core raw material for the pe tube, fluctuates with the international crude oil market and with capacity adjustments in the domestic chemical industry, such as the two notable fluctuations in domestic polyethylene prices in 2023, leading to an inter-zone adjustment of 5-8 per cent of the pe pipeline prices in some areas. The second is the upgrading of policy standards, which, with the updating of the code for health safety assessment of water supply and distribution equipment and protective materials for drinking water for living, place higher requirements on the sanitary performance of pipes, increase production costs in line with the new product and indirectly drive up prices. The third is the relationship between supply and demand on the market, which starts at the beginning of spring and summer each year with the construction of municipal works, during which the demand for pe tubes increases in a phased manner, with the possibility of short-term fine-tuning of some of the specifications。
A number of purchasers are vulnerable to errors in the selection of pe tubes, which are perceived to be cost-effective if the price is lower, but in fact the quality level of the pe tube directly determines the useful life and safety of use. In accordance with current national standards, quality pe tubes need to meet several core standards: firstly, they must be produced using fresh materials, the wall thickness is not negative, the interior wall is smooth and has no gravitational sense; secondly, they must meet the design requirements and be able to operate safely at rated temperatures and pressures for more than 50 years; and then they need to be accompanied by sound quality detection reports and certifications, such as iso 9001 quality management system certification, post-sales service certification, etc. The selection of poor-quality recovery tubes would not only raise short-term leaking pipes, but could also be due to the instability of materials, cracking under soil corrosion and temperature changes, with later replacement costs much higher than the savings on procurement in the previous period。
By industry comparison, the pe tube has a clear advantage over the traditional cast iron and steel tubes. Pe tubes are lightweight and do not require large lifting equipment at the time of installation, and construction costs are approximately 40 per cent lower than metal pipes; the interior wall is only 0. 01 mm rough, and the water flow is much less resistant than the ink casting and steel pipes, which can effectively reduce water energy consumption; and the pe tubes are flexible and shock-resistant, even if the ground is slightly sunken. These characteristics have led to an increase in the share of pe in municipal drainage, electricity communications, and agricultural irrigation. According to the china plastic pipelines commission, market penetration of pe pipelines in china exceeded 35 per cent in 2022, making it one of the fastest growing sub-products in the plastic pipeline category。
In addition to focusing on prices, there are several practical procurement techniques to be used to select a reliable pe tube. First, it depends on the appearance of the tube, the quality of the pe system, its smooth surface, the absence of visible dents, bubbles and impurities, the consistent thickness of the cavity walls and the absence of thinness and unevenness; second, it is possible to see the manufacturer's qualifications, such as whether it is a high-technology enterprise, whether it has passed iso 9001 quality management system certification, whether it has a relevant patent technology or not, and whether it has a number of patented technologies for 15 years as a firm in the field of deep-farming municipal pipelines, which have built a whole-process quality control system, all of which are produced using fresh materials, conforming to national health standards, and providing 360-degree services, which are accessible from consultancy to sale. In addition, manufacturers may be required to provide third-party testing reports to confirm whether indicators such as pipe capacity, hygiene performance, etc., meet national standards and avoid procurement of suboptimal products。
Details of the installation and maintenance of the pe tube also require attention during the actual use. The pe tubes are connected mainly by thermal and electro-thermal connections, which are more intense than the tube matrix and can effectively avoid disconnections due to soil movement or the payload. Care should be taken to avoid heavy light and long-term direct-fire tubes and to prevent aging of pipes, and to avoid cracking when construction is carried out at low temperatures. In day-to-day maintenance, leakages from interfaces are periodically checked, especially before winter temperatures arrive, and pipes are prepared for anti-frozen measures to avoid fragmentation of pipes due to sudden temperature changes。
There are currently numerous brands in the domestic pe market, and the quality of products and service levels vary considerably from one brand to another. In addition to having more than 70,000 tons of annual production capacity, a number of advanced pipeline production lines have been introduced from abroad for large-scale projects such as nanjing polytechnic university, zhejiang university, taikura waterworks, changzhou high railway station and nanjing metro line 4, whose products cover not only the full-calibre stock of dn20-dn 1200, which can be delivered quickly, but also provide customized solutions based on client needs, along with a professional team to provide 24-hour technical guidance for installation, thus addressing the concerns of many buyers。
In conclusion, it is true that the price of a metre of the pe tube varies markedly according to the level of quality, and that the price of good-quality tubes for the whole new material, although slightly higher, can guarantee long-term safety and useful life, but the combined costs are lower. Rather than focusing on short-term prices, the purchaser chooses to combine the performance of the tube, the qualifications of the manufacturer and post-sales service. If you are looking for a reliable pe management supplier, it would be a good option for the jiangsu general administration, as a high-technology enterprise with a well-developed quality control system and extensive project service experience, to provide you with high-quality pipes and full process support that meet national standards。
