Second of fence decoration-Water Supply Pipe Fittings

ProgramIt is not easy for staff xdjm to buy a house. It has been made by a developer or a second-hand house, and cannot be swallowed up by a clothing manufacturer, building material dealer, a furniture merchant, or a soft clothing supplier. We need to arm ourselves with knowledge and fight together with js to the end. Let's take a look at the fence home decoration series compiled by Leng Shan. pdf: http://download.csdn.net/source/1726999 Quiet Decoration: http://blog.csdn.net/magus_yang/category/826768.aspx
2.1. PPR pipe purchase and installation

Considerations for PPR pipe Purchase:
1. Appearance, high-quality Pipes use 100% imported PPR raw materials, smooth appearance, complete identification, and anti-counterfeit identification of accessories.
2. toughness, good pipe toughness, can be easily bent into a circle, without breaking. Poor quality water pipes are brittle, and they are broken when bent.
3. thermal expansion and contraction, good pipe at 90 degrees of water temperature, still can maintain hardness. Inferior water pipes are softened at a temperature of 60 degrees.
4. The service life is long, the quality product is guaranteed to be 50 years, and the inferior product is only 5-6 years.

The most common problem with PPR pipes is water leakage, which must be standardized during installation:
1. When using a metal threaded PPR pipe, full sealing tape must be used to avoid water leakage at the thread;
2. Do not tighten the pipe fittings to avoid leaking due to cracks;
3. It is recommended that the two ends of the pipeline be cut off at 4-5 cm points;
4. During winter construction, avoid pressure, hitting, collision, and throw on pipelines;
5. After installation, you must perform a pressurization test. The pressure test time is 30 minutes and the test duration is 8-10 kg;
6. It is best to take the pipe to the top to facilitate maintenance. If you go underground, it is difficult to find water leakage. In addition, if you find that the wall paint is moldy, the skirting or wood floor is black and has fine bubbles, the canopy and the wet water seepage of the tube wall tiles should be checked as soon as possible;

PPR pipes have many advantages, including economic, non-toxic, light weight, corrosion resistance, no water leakage, no scaling, high reliability, and high cost effectiveness;
The disadvantages of PPR pipe are: high temperature resistance, poor pressure resistance, and limited length. A large number of connectors are required if the pipeline is too long or too long to be laid, and the accessories are expensive;

PPR pipe specifications mainly have two indicators:
Pipe diameter, ranging from 16mm to 160mm, commonly used in home decoration is 25mm of 6 in charge;
Wall thickness, commonly used 8mm cold pipe, marked with a blue line, 2mm of the hot water pipe is marked with a red line;

Components of the PPR pipe include:
There are three commonly used connectors for home decoration, which are generally welded to the pipe. A bundle is used to connect two pipelines when the pipelines are not long enough. The elbow is divided into right-angle bending and 45-degree bending. It is used when the pipe needs a corner. The three links are used to connect the water pipes in three directions.
In addition, there are internal and external wires used to connect the faucet, water meter and other types of water pipes. Silk pieces are commonly used in home decoration.
The curved line is used when the two water pipes intersect on the same plane and are not docked.
The plugging head is also called the stuffy head. After the pipe is installed, it is used to temporarily close the outlet. It is removed when the faucet is installed.
The valve is also called a ball valve, used to open and close the water flow.
