induction preheating before welding steel pipe

Induction Preheating Before Welding Steel Pipe

This induction heating application shows the preheating of steel pipe before welding with 30kW air-cooled induction power supply and air-cooled coil. Inductively preheating of the pipe section to be welded ensures faster welding time and a better quality of the welding joint. Industry: Manufacturing Equipment: HLQ 30kw air cooled induction heater Time: 300 secs. Temperature: Required from ambient temperature 600 ° C +/- 10 °C (1112° F/ +/- 50°F) Materials: Steel pipe Details for butt-welded steel pipe: Total length: 300 mm (11.8 inch) DIA: 152.40 mm (5.9 inch) Thickness: 18.26 mm (0.71 inch) Heating length: 30-45 mm from middle (1.1 – 1.7 inch) Details for butt welded steel plate. Total size: 300 mm (11.8 inch) X 300 mm (11.8 inch) Thickness: 10 mm (0.39 inch) Heating length: 20-30 mm (0.7-1.1 inch) from middle. Fixture details for butt welded steel pipe: Material: Mica. Total Size: 300 mm (11.8 inch) X 60 mm (2.3 inch) Thickness: 20 mm (0.7 inch) Withstands temperature of 900 °C (1652°F) Process: We are using our mobile air-cooled 30kW induction heating system which allows us to easily move the system and the heating coil to various welding locations, without the need to provide additional water cooling systems or hoses. Induction heating provides consistent heat throughout the process. The preheat temperatures can be easily measured with temperature monitoring tools. The induction heating method is very efficient because it minimizes the heat loss that often occurs during other heating methods.
