1. The surface power is large, which is 2 to 4 times the surface load of air heating.
2. Highly intensive and compact structure. Because the whole is short and dense, it has good stability and no bracket is needed for installation.
3. The combined type mostly uses argon arc welding to connect the electric heating tube to the flange, and can also use the form of a fastening device, that is, each electric heating tube is welded with a fastener, and then the flange cover is locked with a nut. Adopt argon arc welding with fasteners and never leak. The fastener seal adopts scientific technology, and the replacement of a single piece is extremely convenient, which greatly saves future maintenance costs.
4. Choose imported and domestic high-quality materials, scientific production technology, and strict quality management to ensure the superior electrical performance of the electric heating tube.
