Post-Welding Heat Treatment Device
Pipeline medium frequency induction heat treatment system is a special heat treatment equipment specially developed for pipeline prefabrication by Nanjing NAEC Automation Co., LTD. This system adopts the principle of medium frequency induction heating, which is specially used for the heat treatment of weld during automatic pipeline welding. It is a special high-efficiency equipment to improve the efficiency of pipeline welding heat treatment and guarantee the welding quality, and is an ideal heat treatment equipment for automatic welding of thick wall pipes. Under certain working conditions, it can also realize one tow two ways, and heat treatment of two welding joints at the same time.
Equipment characteristics
➤ High heating efficiency: 10 minutes can be uniformly heated to 100 ° C, the highest temperature up to 788 ° C.
➤ Low cost of use: a set of induction cables of this equipment can be applied to multi-specification pipelines, which greatly reduces the number of heating cables used and has low cost of use.
➤ High equipment utilization rate: The equipment uses mobile tooling design, the equipment completes a ring gap heat treatment, can manually promote the mobile platform, to the next station for heat treatment work, convenient transport, high equipment utilization rate.
➤ High safety: Equipment operations are completed on the ground, no open fire or thermal radiation operations, effectively reducing the safety risk of operators.
➤ Multiple control thermocouple input: the hottest thermocouple can be controlled when heating and the coldest thermocouple can be controlled when cold to ensure uniform heating and quality.
➤ Insulation failure protection: When the power supply is short-circuited, the system is automatically cut off, and an induction line directly feedbacks the failure state to the power supply.
➤ Digital recording of the whole process of heating curve: industrial touch screen is used to display 6 real-time temperature curves and record and save. Real-time saving of the working state of the equipment, built-in heat treatment special software, USB interface to read and save data.
➤ High efficiency heating technology: The use of medium frequency induction heating technology, can obtain 90% of the heat energy conversion rate, more power formation system, can realize the welding heating needs of large horizontal cylinder.
Water cooling technology: Heat treatment induction cable using water cooling technology, effectively ensure the cable life and heat treatment efficiency and heating uniformity.
