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.
