"The demand for municipal pipe network transformation has been released, and pipe selection has become a core influencing factor."
Recently, many places across the country have launched special projects to upgrade urban old pipe networks, covering water supply, drainage, gas and other areas of people's livelihood pipelines. This year, municipal pipe network renovation projects in Hubei have been intensively landing, and many projects involve the replacement of old pipelines that have been built for more than 20 years. The adaptability of pipes directly determines the service life, operation and maintenance costs, and the stability of people's livelihood services. It is the core consideration for the early selection of projects.
"Core Performance Requirements for Special Plastic Pipes for Municipal Reconstruction"
The special plastic pipes for municipal renovation in Hubei must first meet the weather resistance requirements, adapt to the climate characteristics of high temperature, high humidity in summer and low temperature frost heave in winter in Hubei, and meet the anti-aging performance standards of the pipe wall to avoid cracking and leakage problems in the short term; secondly, it must have excellent anti-sedimentation, acid and alkali corrosion resistance, and adapt to the complex environment of soft soil geology and underground sewage and soil corrosion in some areas of Hubei; the pipes used in water supply pipelines must also meet food-grade hygiene standards to avoid secondary pollution of water quality; at the same time, it is required to be easy to install, and can be quickly connected by hot melt, electric fusion, etc., to shorten the construction period of road occupation and reduce the impact on the daily travel of citizens.
"Key points for attention in the construction and operation and maintenance of plastic pipes"
Before the construction of municipal pipelines, it is necessary to confirm the connection process according to the geological conditions of the project and the use of the pipeline. Strictly control the temperature and the docking time during the hot melt connection to avoid the problem of virtual welding and leakage welding; the buried depth of the pipeline needs to meet the requirements of municipal engineering specifications, and the backfill is preferentially filled with fine sand to avoid gravel and sharp debris scratching the pipe wall. During the operation and maintenance stage, the pipeline endoscopy detection technology can be used regularly to check the loss of the pipe wall, and deal with small-scale hidden dangers in a timely manner, which can extend the actual service life of the pipeline to more than the
As the core material for the transformation of old pipe networks, plastic pipes with strong adaptability can effectively reduce the operation and maintenance costs of the whole life cycle of the pipe network, ensure the safety of municipal pipeline operation, and help Hubei municipal renovation projects to improve people's livelihood.
