Specification introduction of water pipe joint

In our daily life, we need to drink water every day. But do you know what a water pipe joint is? Water pipe connector is used to connect water and water pipe connector. According to the use method, water pipe joints can be divided into external thread-terminated water pipe joints and ferrule-type water pipes. In fact, water pipe joints will come into contact with each of us in our lives. Don't underestimate this joint. If the specification is not selected correctly, it will bring a series of troubles to everyone's future use. Today, Bian Xiao will introduce the specifications and other aspects of water pipe joints in detail!

What is a water pipe joint?

What is a water pipe joint? The raw material of water pipe joint is mainly zinc alloy die-casting, and the surface is chrome-plated, galvanized and sanded. Compact structure, no air holes and high strength, it is one of the most widely used decorative accessories today. Widely used in high-end buildings, hotels, hospitals, buildings, gymnasiums, museums, government agencies, villas and residential quarters.

Specification of water pipe joint

Nominal diameter (i.e. approximate inner diameter):? How much (in mm) is DN used in engineering design? 4 points =DN 15, that is, the inner diameter is about 15mm, the outer diameter plus pipe thickness is about 20mm, and so on, 4 points =DN 15? 6 points =DN20, 1 inch =DN25.

4 branches =DN 15 (nominal diameter: 15)=4/8 inch = 1/2 inch 6 branches =DN20 (nominal diameter: 20)=6/8 inch =3/4 inch 8 branches =DN25 (nominal diameter: 25) =

Therefore, the word XXX refers to inches, and the nominal diameter is neither the outer diameter nor the inner diameter, which is the size matched with the standard pipe fittings.

Specification of aluminum-plastic pipe joint, such as 12 16 *12m,1620 *12m, 1620*3/4M,12. * 1/2: refers to the end with an inner diameter of 12? MM, outside diameter 16? MM aluminum plastic pipe, the other end of which is connected with the external teeth of 1/2; 1/2 tooth indicates that the thread diameter is 20? Hmm.

1620*3/4 inner wire tee: refers to the inner diameter 16? Well, the outer diameter is 20? MM aluminum plastic pipe; One end is 6 o'clock =3/4=D20=25? MM screw? ; 12 16* 1/2F？ It is a 4-branch pipe with an inner diameter of 12? Outside diameter: 16? Thread 20? Hmm? ; 1620* 1/2F？ Is it a 6-branch pipe with an inner diameter of 16? Outside diameter: 20? Thread 20? Hmm? .

Installation of water pipe joint

How to install the water pipe joint? Before that, you need to know the composition of each original. Water pipe joints mainly include: elbows, reducing elbows, inner and outer wire elbows, tees, reducing tees, inner wire joints, reducing inner wire joints, outer wire joints, inner and outer wire joints (sleeves), caps, plugs and movable joints. If PPR pipe is selected, it can be welded by hot melt machine; If the iron pipe is used, it is necessary to set the wire with a silk machine first, and then wrap it with hemp yarn or raw material tape.

1) installation, it is best to clearly understand the uses and advantages of different types of water pipe joints, and choose appropriate raw materials.

2) Pay attention to the installation position. Water pipes buried in the wall cannot have joints.

3) When connecting the water pipe, close the water valve first, and then open the test.

4) When installing the joint, align it, so as to avoid loosening the joint and causing water leakage at the joint. Once welded, it is troublesome to take it off. Owners who have no confidence in the installation can ask special decoration personnel to operate, so as to avoid problems after the joint.

What should I do if the water pipe joint leaks

Water pipe joint is an important part. The water leakage of water pipe joint is different from other parts, so it can't be repaired, and only the water pipe joint can be replaced. Generally speaking, if you are not sure you can solve the problem yourself, you can ask a specialized expert to handle it.

1. When the connector leaks, remove it. If rust is difficult to remove, you can use a hacksaw. Only when you don't touch the thread of the water pipe can you cut a hole and unscrew it with a pipe wrench.

2. Whether the rubber pad is aging and needs to be replaced with a new one. Coat the silk mouth with a thick layer of white paint, and then pack it with hemp (or raw material tape).

3. If there is water leakage at the joint or weld, if you can't solve it yourself, you'd better ask relevant professionals to help you deal with it.

The above is the introduction of the specifications of water pipe joints summarized by Bian Xiao, and this is the end. I believe that after reading the specifications of water pipe joints summarized by Bian Xiao, you must have a comprehensive and in-depth understanding of the specifications of water pipe joints. Now, let's see if the specifications of your water pipe connector are suitable for your faucet. Although you can't see the problem now, it will show up after a long time. Finally, I hope that Bian Xiao's summary can help everyone.
