3PE anticorrosive spiral steel pipe for buried water supply pipeline.
With the acceleration of urbanization, the quality and safety of water supply pipelines, as an important part of urban infrastructure, have attracted more and more attention. In order to improve the anti-corrosion performance and service life of water supply pipelines, 3PE anti-corrosion spiral steel pipes have gradually become the preferred material for buried water supply pipelines. This article will introduce in detail the characteristics, advantages, applications and precautions of 3PE anticorrosive spiral steel pipes for buried water supply pipelines.
1. Features and advantages of 3PE anticorrosive spiral steel pipe.
3PE anti-corrosion spiral steel pipe is a three-layer structure anti-corrosion steel pipe, which is composed of an inner layer, an intermediate layer and an outer layer. The inner layer is made of food-grade epoxy powder coating, which has excellent adhesion and corrosion resistance; The middle layer is the adhesive, which plays the role of connecting the inner layer and the outer layer; The outer layer is made of high-density polyethylene (HDPE) material, which has excellent mechanical properties and anti-aging properties.
Compared with the traditional single-layer or double-layer anti-corrosion steel pipe, 3PE anti-corrosion spiral steel pipe has the following characteristics and advantages:
1.The anti-corrosion layer is continuous and complete, without pinholes and wrinkles, which can effectively prevent the corrosion of steel pipes by chemicals and microorganisms in the soil.
2.Excellent mechanical properties and durability, able to withstand large pressure and friction, not easy to damage.
3.No waste, waste water and waste gas are produced in the production process, which meets the requirements of environmental protection.
4.The construction is convenient and fast, and does not require special anti-corrosion treatment, and can be directly buried in the soil.
5.The service life is long, which can reach more than 50 years, reducing the frequency and cost of repair and replacement.
Second, the application of 3PE anti-corrosion spiral steel pipe.
Due to the above characteristics and advantages, 3PE anti-corrosion spiral steel pipe has been widely used in buried water supply pipelines. Application scenarios include:
1.Urban water supply system: As the main material of urban water supply pipeline, it is used to connect water sources and users to ensure the water demand of urban residents.
2.Sewage treatment system: It is used for anti-corrosion treatment of sewage pipelines to prevent corrosion and pollution of sewage pipelines.
3.Chemical pipelines: used to transport various corrosive media, such as acid, alkali, salt, etc.
4.Agricultural irrigation system: It is used for the anti-corrosion treatment of irrigation pipes to ensure the quality of irrigation water and the growth of crops.
5.Other piping systems that require anti-corrosion treatment.
3. Precautions for 3PE anti-corrosion spiral steel pipe.
Although 3PE anticorrosive spiral steel pipe has many advantages, the following points need to be paid attention to during use:
1.Before installation, the appearance quality of the steel pipe should be checked to ensure that there are no scratches, dents and other defects, and on-site sampling inspection should be carried out in accordance with relevant regulations.
2.Mechanical damage to the steel pipe should be avoided during installation, so as not to damage the anti-corrosion layer. At the same time, it should be fixed and supported according to the design requirements to avoid excessive pressure or bending stress on the pipeline.
3.In the process of use, the pipeline should be regularly inspected and maintained, and possible corrosion and damage problems should be found and dealt with in time. Defects and damages found should be repaired and replaced in a timely manner.
4.In the design and selection of pipeline system, soil conditions, hydrogeology and other factors should be fully considered, and appropriate pipe diameter, wall thickness and other parameters should be selected according to the actual situation. At the same time, the tightness and pressure resistance of the pipeline system should be ensured to ensure the quality and safety of water supply.
5.During the construction process, attention should be paid to protecting the anti-corrosion layer on the surface of the steel pipe to avoid scratches or friction during transportation and installation. At the same time, attention should be paid to the health and safety of the construction environment to avoid pollution or injury to the environment and personnel.
