How to calculate the center distance of U-shaped heating tube?
The pipe diameter of the U-shaped heating tube determines its pipe diameter radian, and the pipe diameter radian determines the center distance of the U-shaped heating pipe. The standards are as follows:
Pipe diameter: 8 mm R≥15 center distance=30 mm
Pipe diameter: 10 mm R≥20 center distance=40 mm
Pipe diameter: 12 mm R≥25 center distance=50 mm
Pipe diameter: 14 mm R≥30 center distance=60 mm
Pipe diameter: 16 mm R≥35 center distance=70 mm
Pipe diameter: 18 mm R≥40 center distance=80 mm
Pipe diameter: 20 mm R≥45 center distance=90 mm
Pipe diameter: 22 mm R≥50 center distance=100mm
Pipe diameter: 24 mm R≥55 center distance=110mm
Pipe diameter: 25 mm R≥60 center distance=120mm
When the diameter of the heating tube is 8mm, its tube diameter radian is 15, and the center distance of the U-shaped heating tube is 30mm.
When the diameter of the heating tube is 10mm, its tube diameter radian is 20, then the center distance of the U-shaped heating tube is 40mm, and so on.
The relationship between the center distance of the U-shaped heating tube and the tube diameter and the tube diameter radian is shown above. When we know one of the parameters, we can roughly deduce the other two parameters.
