1. High surface power, 2 to 4 times the surface load of air heating. 2. Highly dense and compact structure. Due to its short and dense overall design, it has good stability and requires no bracket for installation. 3. The combined type mostly uses argon arc welding to connect the electric heating tube to the flange, or it can be in the form of a fastening device, where each electric heating tube is welded with a fastener, then locked with the flange cover using nuts. The tube and fastener are welded by argon arc welding, ensuring no leakage. The sealing part of the fastener adopts a scientific process, making single tube replacement extremely convenient, greatly reducing future maintenance costs. 4. Imported and domestic high-quality materials, scientific production processes, and strict quality management ensure excellent electrical performance of the electric heating tube.  |
