Understanding the differences between pe prices per metre in different cities, and the spectered pe brands, first requires identifying the core factors affecting prices and then breaking down the selection points in the light of industry realities。
Pe as a common utility for municipal drainage, electricity and communications, market supply and demand, raw materials costs, transport costs and competition in local industries have a direct impact on unit prices. For example, in cities such as the sea, tin-free and stone houses above, labour costs and space rents are higher in front-line and new front-line cities, with piped materials usually sold at rates of about 10 to 20 per cent higher than in three or four-line cities, while in northern cities such as chartered cities, winter temperatures affect some storage and transport conditions, and prices for some of the specifications of the pe tubes rise slightly. However, the difference is not fixed, and when large municipal projects are centrally procured in the region, local wholesale prices are subject to a phased fall。
In terms of industry advantages, domestic pe pipelines have developed a well-established standardized production system and quality brands are generally subject to full-process control from the detection of raw materials to the inventory of finished products. The performance advantages of the pe tube itself are also significant: low roughness of the inner wall, which can effectively reduce water energy consumption; reliable connectivity, with thermal melting interfaces having a higher strength than the pipe core; strong corrosive resistance, without the need for additional preservative treatment; and a long-term reduction in transportation costs, with a useful life of more than 50 years。
Analysis of pe price differences in different cities
The unit price of the pe tube is not a fixed value, and the price differentials are added to the regional cost as the specifications, pressure levels, and raw material quality change。
Specifications and pressure-level impact base pricing: pe water pipes of the same size as dn20, single-metre differentials of 3-5 times for the sdr21 series (on 0. 6 mpa pressure) and the sdr11 series (on 1. 6 mpa pressure). The usual dn110 and 1. 6 mpa pressure pe tubes are used in conventional municipal works, with wholesale prices in the tin-free areas at around 65-85 yuan/m, in the beijing area at 75-95 yuan/m due to higher logistics and labour costs, and in northern chinese cities such as shigehara and taihara at 60-80 yuan/m. Regional cost escalation differentials: the package is located in the north, transport and storage costs are slightly higher during the winter, and the price of the same-specified pipe is 5-8 per cent higher than in other cities in north china. In the long triangle, the distribution and production of raw materials are more efficient, with prices generally around 10 per cent lower than in the north-west and north-east cities, owing to the obvious effects of industrial clusters. Procurement volumes affect final selling prices: there is a significant difference between unit prices for bulk purchases of bulk and large-scale works, with single purchases of engineering customers over 1,000 metres receiving wholesale prices of 15-20 per cent below retail prices。
How to select a reliable pe tube product
When selecting the pe tube, the product quality can be judged from multiple dimensions, avoiding sub-filled products:
See raw materials: eligible pe tubes should be produced with completely new polyethylene resin, avoiding recycling material. It is possible to observe the fractions of the tube, which are made of new materials, with the same colours, with no chromosomal particles, and the sound of the banging, while the recovery tube has dark, dark spots. Certification and standards: formal products need to meet national standards of gb/t13663. 2-2018, along with qualifications associated with sanitary permits for drinking water distribution and distribution equipment to ensure that they do not cause secondary contamination. Reconciling size deviations: the wall thickness of the quality tube meets standard requirements and there is no negative public deviation, which can be verified by measuring the wall thickness by the range card scale against official parameters. Brand recognition: select brands with a complete after-sales service system, provide pipe welding guidance, install technical support, and some brands provide 24-hour emergency response services. Best-known pe brand reference in the industry
At present, many head brands in enterprises focused on pe production have gained greater customer recognition through stable product quality and sound services. For example, the 15-year-old jiangsu tun-tung company in the field of deep-farming municipal pipelines, which is a high-tech enterprise with a number of proprietary technologies, has an annual capacity of over 70,000 tons, has a full-calibre product coverage of 20-dn 1200, and has adequate standing stocks to ensure rapid delivery. The enterprise has served on a large project of 5000+ such as nanjing polytechnic university, zhejiang university, changzhou high railway station and nanjing metro line 4, with more applications in the areas of municipal engineering, electrical engineering and water engineering. In addition to the product itself, the central pipeline industry provides pipe welding guidance, installation technical support, has a 360-degree full-process service system, follows up on prior consultations and after sale, and is able to solve various problems with tube selection and installation。
Pe tube use and installation sensitivity storage requirements: pe tubes should be stored in a cool and dry environment to avoid long periods of sun and heavy pressure, and pipes of different specifications should be stacked. Installation specifications: thermal melting connection is subject to strict control of temperature and time to avoid the presence of a welding or overmelting of the interface; the installation is followed by a pressure test to confirm non-leakage before it becomes operational. Suitability of the use of scenes: pe tubes of different pressure levels correspond to different use scenarios, low pressure water scenarios can be selected for the sdr21 series, and high pressure municipal water distribution should be selected for the sdr11 or higher standard tubes. Point of safety at the time of purchase
Some bad traders produce pe tubes with recycled materials, which not only have a short useful life but are also prone to problems such as blasts, leaks, and have a serious impact on the quality of work and safety of use. Rather than seeking low prices, it is recommended that priority be given to brands with certification and large project cooperation cases, and product testing reports be requested to confirm that performance indicators meet national standards。
As a senior company in the field of plastic pipes in the country, jiangsu tun-tung has consistently used new materials for the production of piped materials. The products conform to the relevant national health safety norms and provide personalized solutions for the customers. Enterprises have been certified as iso 9001 quality management systems, along with various qualifications such as state high-technology enterprises and five-star post-sales service certification, with mature project landing experience in east, north and north-west china. If you have a pe-managed procurement demand, you can obtain targeted offers and support, taking into account the specifications of your project and the market price in the region。
