T-joint welded steel pipes for urban water transportation

The urban water supply transportation system is an important part of urban infrastructure. It is responsible for transporting treated water from the water source to every user in the city. In this system, T-joint welded steel pipes are widely used in pipeline construction of urban water supply projects due to their special manufacturing process and performance characteristics.

The urban water supply transportation system is an important part of urban infrastructure. It is responsible for transporting treated water from the water source to every user in the city. In this system, T-shaped welded steel pipes are widely used in pipeline construction of urban water supply projects due to their special manufacturing process and performance characteristics.

Application fields: T-shaped welded steel pipes are widely used in petroleum, chemical industry, natural gas transportation, piling and urban water supply, heating, gas supply and other projects.

Material classification: According to the material, T-shaped welded steel pipes can be divided into carbon steel coiled pipes, low alloy coiled pipes, high alloy coiled pipes, stainless steel coiled pipes, etc.

Dimensions and specifications: T-shaped welded steel pipes can produce steel pipes with a diameter of more than 500mm and a wall thickness of less than 150mm, which makes it very suitable for large-diameter water supply and transportation projects.

Production process: The production process of T-shaped welded steel pipe includes raw material preparation, leveling, trimming, planing, forming, welding, weld processing, non-destructive testing, heat treatment, straightening, sizing, quality inspection, anti-corrosion treatment, cutting and packaging Wait for steps.

Quality requirements: The urban water supply engineering planning specification GB 50282-2016 mentions that the quality of drinking water should comply with the national standard "Hygienic Standards for Drinking Water" GB 5749, which means that steel pipes used to transport drinking water must also meet certain requirements. Water quality safety standards.

Safety: Engineering facilities in the urban water supply system should not be set up in unfavorable geological areas prone to landslides, mudslides, collapses, floods and low-lying waterlogging areas to ensure water supply safety.

Specification requirements: Specific technical requirements related to urban water supply are mentioned in the "Outdoor Water Supply Design Standard" GB 50013-2018. These requirements are also applicable to water supply projects using T-shaped welded steel pipes.

Technical Regulations: Technical Regulations for Building Water Supply Metal Pipe Engineering CJJ/T154-2011 provides the connection requirements for building water supply metal pipes, including threaded connections, welded connections, grooved connections, flange connections, etc. of carbon steel pipes. These regulations are for T-shaped welding The installation and use of steel pipes are instructive.

Standard selection: GB/T 28708-2012 "Regulations on the Size Selection of Seamless and Welded Steel Pipes for Pipeline Engineering" provides a standard basis for the size selection of seamless and welded steel pipes in pipeline engineering. The selection of T-shaped welded steel pipes should also comply with this standard.

Construction and acceptance: GB 50268-2008 "Code for Construction and Acceptance of Water Supply and Drainage Pipeline Projects" stipulates the requirements for the construction and acceptance of water supply and drainage pipeline projects. The construction and acceptance of T-shaped welded steel pipes also need to comply with these regulations to ensure the quality of the project.

In summary, the application of T-shaped welded steel pipes in urban water supply transportation must comply with relevant national standards and specifications to ensure water quality safety, project quality, and long-term stable operation.
