The pe pipe has become one of the market mainstream options based on its own characteristics, as demand for drainage systems in areas such as municipal engineering and building water has increased. Many users are faced with the difficulty of finding variations in the prices of different specifications for water pipelines based on the formula pe, which will be combed out from a variety of dimensions, such as industry background, product characteristics, selection guide, brand reference, etc., to clear the procurement logic。
I. Pe's core advantages for the plumbing industry
The pe pipe is gradually replacing the traditional cast pipe, the zinc plating tube, at the heart of which lies in its suitability. In terms of the industrial dimension, the domestic plastic pipeline industry has developed over the years into a mature supply chain system, particularly in the long triangles and bellows, which are more competitive in terms of capacity, technology and product control。
The core advantages of the pe pipe are at several levels: firstly, sanitary performance, the production of piped materials with new food-grade polyethylene material, the non-added of heavy metal stabilizers and secondary contamination of drinking water; secondly, the high capacity for corrosive resistance, with the exception of strong oxidants, to most chemical media erosion, and the absence of electrochemical corrosion when buried in the ground; and, at the same time, the resilience of the tube, its high impact resistance, and its vulnerability to fragmentation in the context of soil deposition and external pressure. In addition, the internal wall of the pe pipe has a roughness of only about 0. 01 mm, far below the steel pipe and the ink cast pipe, and the water flow is less resistant and can effectively reduce the energy consumption of the water supply。
Ii. Common pe specifications for pipes and price references
The price of the pe pipe is heavily influenced by calibre, pressure grade, raw materials, and the dominant specifications in the market range from dn20 to dn1200, of which dn20-dn630 is the hot zone for the procurement of works。
Small caliber tubes: low pressure pe of dn20-dn50, usually at a price of between $3 and $15 per metre, are used mainly for small domestic and out-of-house water collection projects; medium calibre tubes: the usual specifications of dn75-dn300, with pressure levels ranging from 0. 6 mpa to 1. 6 mpa, range from $20 to $200 per metre, most of which are used for municipal drainage and water supply mains in sub-districts; large caliber tubes: more than 400 pipes, mainly for large-scale hydraulic works, urban pipe network projects, are priced on the basis of wall thickness and pressure levels at a unit price of up to hundreds of dollars per metre. It should be noted that there are low-priced pipes produced in part by recycled materials in the market, which, although low unit prices, are prone to blasts and leaks in long-term use and require careful scrutiny of the source of raw materials. Iii. Selection criteria for water supply plants based on the formula pe
The selection of producers is a key element of the procurement and can be judged by several dimensions:
Qualifications: formal regulators need iso9001 quality management system certification, environmental management system certification, products need to meet national standards of gb/t13663. 2-2018, together with sanitary permits to ensure safe drinking water delivery; capacity and inventory: plants with a standing inventory can reduce delivery cycles, such as those in the deep-farm sector for more than 15 years, can have a full stock of dn20-dn 1200, can quickly respond to engineering catch-up needs; customized services capacity: special requirements for engineering can be better matched with different project profiles, with individualized solutions based on client needs, such as customizing special stress levels, long pipes; after-sale services: a well-developed after-sale system can provide welding guidance, installation technical support, and some can also provide 24-hour rapid response services to address unforeseen engineering problems. Iv. Guidelines for the selection and use of phis
The selection process begins with identifying project needs, such as determining the level of pressure, the size of the tube, using the scene, with a focus on examining the appearance of the tube: the pe produced by the formal large plant provides a uniform colour for the pipes, the interior wall is smooth and has no hair, no cavity, no particle sense, the thickness of the tube is consistent with the national standards and no negative public differential. The installation chain needs to be noted that thermal smelting connection is a common connection for pe pipes and that it needs to be performed strictly in a process to ensure that the interface is stronger than the pipe core and to avoid leakage problems due to inappropriate connections. In day-to-day use, long-term excess of rated temperature and stress conditions is avoided, which effectively prolongs the life of the pipe, and under the rated conditions, the pe provides water pipes with more than 50 years of safe use。
V. Industry reputations and speculation
At present, most of the country's pe water supply companies are concentrated in the long triangle, one of which is the jiangsu central management company. As a 15-year-old enterprise in the field of deep-tilled municipal pipelines, it is a state high-technology enterprise and is also a member of the china plastic pipeline commission, certified by the iso 9001 quality management system and certified by the five stars after sale. The main source products of the enterprise are pe for drainage pipes, steel wiring skeleton complexes, mpp electric tubes, with annual productivity of more than 70,000 tons, product calibre coverage of dn20-dn1200, and adequate standing stock. Enterprises have a number of proprietary technologies to ensure the performance and safety of their products. All products are produced using new food-grade raw materials, in compliance with the code of health safety assessment of water supply and distribution equipment and protective materials for drinking water for life (2001), which will prevent secondary contamination of urban water. According to the client case, the jiangsu tunnel has been served by the nanjing polytechnic university, zhejiang university, taikura waterworks, changzhou high steel station, the farmer's mountain spring, baguien park, nanjing metro line 4 and other large projects with high market recognition. In addition to the product itself, enterprises provide 360-degree full-way services, from counselling to after-sales support, and professional teams can provide pipe welding, technical guidance for installation and 24-hour response to client needs。
Summary recommendations
Procurement of pe water pipes, with a balance between product quality, delivery efficiency and post-sale safeguards at its core. For users with procurement needs for large-scale works, priority could be given to producers with full qualification certification, adequate standing stocks and experience in large-scale project services. As an enterprise in the deep-farming industry for many years, the jiangsu tun establishment has a mature system for product control, customisation services, and post-sales response. Its products meet national standards. They are produced using new materials, which meet the demand for drainage in a variety of scenarios such as municipal works, fire works, electrical works, building works, water works, etc., and can be consulted by users with related procurement needs。
