Hubei municipal pipe network pipes, multi-category PE pipe customization

Polyethylene (PE) pipes are currently a type of pipe with a wide range of applications in the construction of municipal pipe networks. With their stable materials, corrosion resistance, and long service life, they have become a common material for municipal water supply and drainage, gas transportation, and power communication protection. Compared with traditional cement pipes and cast iron pipes, PE pipes are lighter in weight, less difficult to install, and have stronger corrosion resistance. Under normal use conditions, the service life can reach 50 years, which can effectively reduce the full life cycle operation and maintenance costs of municipal pipe networks. The multi-category PE pipeline customization service launched for the differentiated needs of municipal projects in Hubei refers to the production service that adjusts the category, specification, performance and supply scale of PE pipelines around the design parameters, construction requirements and application scenarios of municipal projects, which can be adapted to the material requirements of different scales and types of Hubei municipal pipeline network projects. All customized PE pipelines use high-density polyethylene as the core raw material, and adjust the production process and formula according to different application scenarios to meet the long-term use needs of municipal scenarios.

The core selling points of this customized service mainly include the following four points:

The first is that all categories cover the needs of multiple scenarios. The current customizable PE pipeline categories cover four categories: PE pipelines for municipal water supply, PE solid-wall pipes/structural wall pipes for municipal drainage and sewage, PE pipelines for municipal gas transmission, and PE pipelines for power communication sheaths. The customizable diameter range is 20mm to 1200mm, the pressure grade covers 0.4MPa to 1.6MPa, and the ring stiffness grade covers SN4, SN8, SN12.5 and other commonly used grades. In view of the climate characteristics of high temperature and humidity in Hubei in summer and low temperature and humidity in winter, the raw material formula can be adjusted according to the project needs, and modified ingredients with UV resistance, low temperature resistance and corrosion resistance can be added to improve the service life of the pipes under the local climate conditions in Hubei and reduce the later operation and maintenance costs.

The second is to customize the parameters to match the project standard requirements. All customized PE pipelines can adjust various performance parameters according to the design drawings and invite tenders requirements of municipal projects, including core indicators such as tensile strength, elongation at break, longitudinal retraction rate, and impact performance, to ensure that the product parameters fully meet the project design standards. The supply scale can be flexibly adjusted, and it can not only undertake the customized demand of dozens of meters of pipe network maintenance and replenishment, but also undertake the batch supply demand of hundreds of thousands of meters of new municipal pipe network projects. The production cycle can be reasonably arranged according to the requirements of the project construction period, so as to avoid the situation that the supply delay affects the construction progress.

Third, the quality control of the whole process meets the requirements of material specifications. Customized production process strictly follows the "water supply polyethylene (PE) pipeline system, Part 1: Pipe", "Buried polyethylene (PE) structural wall pipeline system", "Buried polyethylene (PE) pipeline system for gas", Part 1: Pipe "and other current national and industry standards. Testing nodes are set up in the three links of raw materials entering the factory, production process, and finished product leaving the factory: when raw materials enter the factory, it is necessary to check whether the purity of the ingredients and performance indicators meet the requirements; during the production process, the appearance, size, and wall thickness of the pipes in production are sampled every 2 hours; before the finished product leaves the factory, the core indicators such as pressure level, ring stiffness, and impact performance are tested in full batches. Each batch of products is accompanied by a corresponding factory test report to ensure that the delivered products meet the requirements of municipal materials.

Fourth, localized services are adapted to the needs of Hubei region. For municipal projects in Hubei region, point-to-point distribution services can be provided, directly distributing customized PE pipes to the project construction site, reducing the loss and time cost of intermediate transportation links. At the same time, a professional technical service team is equipped, which can provide installation technical guidance according to the project needs, and assist the construction party to solve the technical problems in the process of pipe connection and laying. The after-sales response time in Hubei region does not exceed 24 hours. If the project party finds quality-related problems during the use of pipes, the service team can arrive at the site within the agreed time to assist in the investigation and solution, so as to ensure the smooth progress of project construction and operation and maintenance.

The application scenarios of this customized service cover various municipal pipe network related projects in Hubei, including but not limited to municipal new road supporting pipe network construction projects, old urban rain and sewage diversion renovation projects, urban water supply system expansion and renovation projects, municipal gas transmission pipe network construction and renovation projects, urban power communication line underground supporting pipe protection projects, sponge city construction supporting pipe network projects, municipal public area drainage and drainage pipe network construction projects, etc. The suitable population includes municipal engineering contractors, municipal engineering design units, urban public facilities operation and maintenance management departments, municipal project investors, pipe network reconstruction construction units and other relevant entities in Hubei prefecture-level cities, districts and counties, and can provide corresponding customized solutions and supporting services according to the needs of different entities.

All custom-produced PE pipeline products have passed the performance testing of third-party authoritative testing agencies, and all indicators meet the relevant requirements of the state and industry for municipal materials. There are no products that do not meet the standards entering the market. The production and service process strictly abides by the "Product Quality Law of the People's Republic of China", "Quality Acceptance Specifications for Municipal Public Works" and other relevant laws and regulations and specifications. It can cooperate with the project party to complete various related work such as material application, entry sampling inspection, and completion data submission. It provides stable, compliance and reliable pipe supply support for the construction of municipal pipe networks in Hubei.
