Large diameter T-welded pipe is a special steel pipe structure, mainly used for pile foundation construction of large-scale foundation projects (such as bridges, docks, high-rise buildings, etc.).
Large diameter T-welded pipe is a specific type of welded steel pipe used for connecting a branch pipe to a main pipe at a 90-degree angle. These pipes are critical in various industries like oil and gas, water and wastewater, and construction, where large volumes of fluids or gases need to be transported at high pressure.
Structural Features
Large-diameter T-welded pipe is manufactured using a spiral welding process, with welds distributed in a helical pattern. This structure provides the pipe with excellent mechanical properties when subjected to axial and hoop stresses. Its unique structural features include high load-bearing capacity and high rigidity, enabling it to withstand significant lateral pressure and ensuring the stability of the foundation structure during construction and operation.
Manufacturing Process
1. Raw Material Preparation: High-quality steel strips, such as Q235B and Q345B, are selected. These steels have excellent strength and weldability.
2. Spiral Forming and Welding: After pretreatment, the steel strips are fed into the spiral forming machine and welded using a double-sided submerged arc welding process.
3. Welding Parameter Control: Welding parameters such as current, voltage, and speed are precisely controlled to ensure weld quality.
4. Nondestructive Testing: After welding, ultrasonic testing and radiographic testing are performed to ensure weld quality meets standards.
Applications
1. Building Structures
Used as support and reinforcement materials for buildings, bridges, towers, and other structures, ensuring structural stability and safety.
2. Piping Systems
Used in petroleum, chemical, and natural gas transportation, as well as urban water, heating, and gas supply projects, providing reliable sealing and pressure resistance.
3. Steel Structure Construction
Used in the construction of temporary stages, exhibition displays, stadiums, and other structures, providing a stable structure and easy assembly and disassembly.
