How many centimeters is the charge? How many centimeters is responsible for 6?

Water pipes are available in English and metric sizes.

1 foot = 12 inch 1 inch =8 minutes = 25.4 mm. 6 minutes is 3/4 * 25.4 mm =19.05 mm. But for the sake of unification and convenience, the water pipe with 6 minutes in English is weighed as 20 mm This is just the inner diameter. If you want to calculate the total diameter of the water pipe, you should add two wall thicknesses.

For example, a 4-minute hot water pipe has a wall thickness of 3.4mm, an inner diameter of 12.7mm and a total diameter of12.7+2 * 3.4 =19.5 mm ≈ 20 mm.

So 4 is responsible for: 20mm, 6 is responsible for: 25 mm.

A connector is a component used to connect water pipes. According to the use mode, water pipe joints can be divided into: external thread terminated water pipe joints, clamping water pipe joints and self-fixing water pipe joints.

The external thread terminated water pipe joint is made of zinc alloy by die casting, and its surface is galvanized, frosted or chrome plated. Compact structure, no pores and high strength.

Extended data:

Application:

The ferrule-type water pipe joint can connect the screw pipe with the hose, which saves the thread processing process and only needs to screw in the screw; Compact structure and high strength.

The self-fixing water pipe joint can connect the outlet of screw pipe-free or threadless equipment with the hose, thus eliminating the threading process; It is made of zinc alloy by die casting, and the surface of hot metal pipe joint is galvanized, frosted or chrome plated; Compact structure and high strength. Widely used in high-end buildings, hotels, hospitals, buildings, gymnasiums, museums, government agencies, villas and residential quarters.
