Spiral steel pipe for Urban water supply and drainage

The spiral pipes used in urban water supply and drainage systems usually refer to spiral welded pipes, which are a common type of steel pipes that are widely used in urban water supply and drainage projects. Spiral welded pipes are named for their unique spiral seams. This type of pipe is manufactured using a spiral forming process that curls steel strips or plates into a cylindrical shape and connects the seams by welding.

Spiral welded pipes are named for their unique spiral seams. This type of pipe is manufactured using a spiral forming process that curls steel strips or plates into a cylindrical shape and connects the seams by welding.

Here are some key points about spiral pipes for urban water supply and drainage:

Manufacturing process: Spiral pipes are manufactured through a spiral forming process, and are welded using automatic submerged arc welding or high-frequency welding to form a continuous spiral weld.

Scope of application: Spiral pipes are suitable for transporting low-pressure fluids such as water, sewage, air, heating steam, etc., and are often used in urban water supply and drainage projects.

Technical requirements: The production and use of spiral pipes must comply with national standards, such as GB/T 3091-2015 "Welded Steel Pipes for Low-Pressure Fluid Transport", etc. These standards stipulate the size, shape, weight, technical requirements, etc. of steel pipes.

Construction technology: When performing spiral jacking construction of long-distance small-diameter pipelines in urban dense areas, special construction technologies may be used, such as auger micro-pipe jacking technology. This technology has the advantages of high pipe jacking accuracy and good impact on the surrounding soil. Advantages include small disturbance.

Innovative technology: In the spiral jacking construction of long-distance small-diameter pipelines in dense urban areas, some innovative technologies may be applied, such as long-distance and high-precision control technology of the auger pipe jacking guide system, long-distance and high-precision control technology of the auger jacking pipe jacking system in sandy and gravel formations Distance continuous jacking technology, grouting drag reduction and anti-locking construction technology during intermittent periods of auger pipe jacking, etc., to overcome difficulties in construction.

Specification requirements: The variety, specifications, and performance of raw materials, semi-finished products, finished products and other products used in urban water supply and drainage pipeline projects must comply with the relevant national standards and design requirements.

Maintenance and safety: Urban water supply and drainage pipeline projects must also comply with relevant maintenance and safety technical regulations, such as CJJ 58-2009 "Urban Water Supply Plant Operation, Maintenance and Safety Technical Regulations", etc., to ensure the safe and reliable operation of the water supply system.

Leakage control: For urban water supply pipe networks, leakage control is also very important. It is necessary to follow specifications such as CJJ 92-2016 "Leakage Control and Assessment Standard for Urban Water Supply Pipeline Networks" to reduce the waste of water resources.

To sum up, during the manufacturing, construction, use and maintenance of spiral pipes for urban water supply and drainage, relevant national standards and specifications must be strictly followed to ensure the quality of the project and the safe and efficient operation of the urban water supply and drainage system.
