1. Height of the U-shaped clamp H = Pipe diameter (with thermal insulation foam) – 5 mm.
2. The material for pipe supports and clamps should meet outdoor application requirements.
3. When the pipe is straight, add a support every 1500 mm. When the direction of the pipe is
changed, add a support at the position that is 500 mm away from the changing point.
