[0017] like Figures 1 to 3As shown, a flange welding bracket for a heating pipe includes a base plate 2, on which a pair of support plates 3 are mounted. A restraining ring 30 is provided at the upper end of the support plate 3. A rotating ring 31 is rotatably mounted within the restraining ring 30. An outer ring 32 is mounted on the rotating ring 31. A movable through-plate 36 is mounted on the outer ring 32. An L-shaped plate 37 is mounted on the inner side of the movable through-plate 36. The L-shaped plate 37 is clamped onto the four edges of the heating pipe 1. A rotating recess 33 is rotatably mounted on the outer ring 32. An inner screw 34 is mounted on the outer side of the rotating recess 33. An end cap is mounted on the outer side of the inner screw 34. The inner end of the inner screw 34 acts on the outer side of the movable through-plate 36. A waist-shaped hole is provided on the rotating concave part 33, and an inner push column 35 is rotatably provided on the inner end of the inner push screw 34. The inner end of the inner push column 35 is tightly pressed against the outer end of the movable wear plate 36. The two ends of the inner push column 35 pass through the waist-shaped hole, and a movable notch is provided on the outer end of the movable wear plate 36. The inner push column 35 is clamped in the movable notch.
