What do you mean by 1 inch 4: 6? How to convert it?

Refers to the straight inner diameter of the pipeline. Because the wall thickness is different, the outer diameter is also different.

As follows:

1. Ordinary 4-branch pipe: pipe inner diameter 15mm, outer diameter 2 1.3mm, and wall thickness 2.75mm..

2. Ordinary 6-branch pipes: the pipe has an inner diameter of 20mm, an outer diameter of 26.8mm and a wall thickness of 2.75mm..

3. Ordinary one-inch pipe: the pipe has an inner diameter of 25mm, an outer diameter of 33.5mm and a wall thickness of 2.75mm.

The conversion unit is:

4 in charge of 1 \ 2 "- pipe diameter12.5mm.

6 in charge of 3 \ 4 "- pipe diameter 19mm?

1 inch pipeline 1 inch pipeline diameter is 25.4 mm.

Expand:

Diameter-When the pipe wall is thin, the outer diameter of the pipe is almost the same as the inner diameter of the pipe, so the average of the outer diameter and the inner diameter of the pipe is taken as the pipe diameter. Usually refers to the general synthetic material or metal pipeline, when the inner diameter is large, the average of the inner diameter and the outer diameter is taken as the pipe diameter.
