Diameter 2470 mm, height 620 mm, top depression depth 45 cm.

Pipe fitting dimensions: Φ610×110mm pipe；Material grade: 12Cr1MoVG Welding preheating process requirement: 200°C; post-welding heat treatment requirement: 730°C. According to the process specifications, four temperature measurement points are established, with controlled temperature <390°C, a heating rate of 80–100°C/h, a holding period of 330 minutes at 730±10°C, and a cooling rate of 80–100°C/h to 390°C.

труб diameter: 8 meters; tube wall thickness: 100 mm; heating perimeter required: 25 meters. Our company employs an induction heating system with a capacity of 80 kW × 3 = 240 kW to perform post-heating hydrogen removal on pipes with a circumference of 25 meters. Materials required for construction: 30 heating elements, 6 connecting cables, and 3 workers. The total installation time is approximately 8 hours; customized heating solutions can further reduce the setup duration. Calculation of the estimated electricity cost savings for this project. Total workload: Total heating length approximately 25 meters Perimeter of a single flange weld: 25 meters. Operating power of the resistance heating equipment: 720 W (60 heating elements, each 10 kW).  Total resistance heating time: 6 hours. Total electricity consumption: approximately 600 kW × 6 = 3600 kWh. O...
