Application of flame preheating in circumferential welding
The circumferential welding process is widely used in fields such as pressure vessel welding, transportation pipeline welding, offshore drilling platform engineering, and wind power main body welding. In order to prevent hydrogen induced cracks during the welding process and ensure the pressure resistance of the workpiece, the workpiece is usually preheated to a specific temperature range before welding.

Forming Of Boiler Corrugated Pipe
Compared with high-frequency heating, the biggest advantage of flame thermal spinning is that it can be carried out simultaneously in the spinning and heating process, which ensures that the workpiece is at the optimal deformation temperature during thermal spinning to the greatest extent.
At the same time, the flame spinning equipment is also equipped with a water cooling system, an automatic ignition system and a flame monitoring system to assist, which is safe, reliable and durable.

High Temperature Spinning of Boiler Corrugated Furnace Liner
Spinning forming technology is an advanced forming technology that can make the continuous local plastic accumulation of the blank into a hollow rotary part. In order to reduce the internal stress of the workpiece and prevent cracking, springback and other phenomena, high temperature heating is usually used to assist in the spinning process. It can not only ensure the uniform texture of the workpiece, but also greatly shorten the processing time and improve the productivity.
