What are the preparation materials for water and electricity decoration? What are the precautions?

1. What materials are used for water and electricity decoration?

1.PPR cold water/hot water pipes: Many people will see all kinds of pipes in cities, but in China, PPR pipes are the mainstream material, and some developed countries use copper pipes more.

2. Pipe fitting: it is the part that connects pipes and pipelines.

3. Type of pipe fittings

A. Straight-through type: also known as sleeve and sleeve joint, it can be used to extend the pipeline when the length of the pipeline is not enough.

B. Elbow: used to rotate the pipeline. Only elbows can change the direction of pipelines. There are generally 45 degrees and 90 degrees of bending.

C the inner screen and the outer screen are connectors for connecting pipes such as faucets and water meters.

D tee: used to connect three pipelines in different directions and extract a pipeline from one pipeline.

E. Plug: used to temporarily seal the outlet. In the process of installing the faucet, it should be removed, and the size should match the corresponding pipe fittings when using it.

F. Crossing the bridge: Two pipelines cross on the same plane, but cannot be aligned. Bridges such as arch bridges should be used to avoid direct pipeline crossing.

G. Stop valve: used to open and close the water flow; H. Pipe clamp: used to fix the position of the pipeline and prevent the pipeline from moving.

4. Water pipes

5. Raw material belt: an auxiliary product commonly used in liquid pipeline installation, which is used at the joint of pipe fittings to enhance the tightness of pipeline joint. Polytetrafluoroethylene is mostly used, which can resist high temperature of 300℃. Strong acid and alkali resistance, high temperature resistance, anti-aging, non-toxic and excellent sealing performance. 6. PVC pipes/connectors/glue

Circuit material type 1. PVC electrical bushing/pipe clamp/switch socket bottom box/junction box 2. Strong line 3. Network cable

4. Closed circuit/telephone line: But now the TV has the ability to connect to the Internet, and the mobile phone has become a fixed telephone. It is recommended not to buy these two lines.

5. Strong and weak electricity box: These two boxes are standard, but some strong electricity boxes will move when decorating the home, and need to be opened by many people. If you want to install them in the box, you must buy them again.

Second, what problems should be paid attention to in the selection of decoration hydropower materials?

(1) Never use PVC as a heat pipe. Because of the characteristics of its own materials, PVC melts when it comes into contact with hot water.

(2) There should be more sockets, especially in bedrooms and living rooms.

(3) When buying decoration and water and electricity, the first thing to consider is safety. Don't be greedy and cheap, and don't take chances.

(4) When purchasing water, electricity and decoration materials, listen to expert advice and don't blindly believe other people's opinions.

3. What is the main content of water and electricity decoration?

(1) List water, electricity and decoration materials and find out the defects. Sometimes you think you have all the materials, but once you list them, you will find that some things are not well thought out, or some things are too heavy to buy;

(2) Making a list of water, electricity and decoration materials can avoid extra expenses. When decorating, you can buy whatever you want. If it is too heavy for a while, it will delay the construction. Third, because time is too tight, you will be in a hurry to buy it. In this case, even if you have enough water, electricity and decoration materials, your decoration effect will be very general.

(3) Making a list of water and electricity decoration materials can give the project a general direction and will not collapse.
