Hydropower construction is one of the hidden projects in the decoration process, which is directly related to the water and electricity consumption in our future life. Therefore, before closing, we must carefully check and accept. So, what do you need to pay attention to in the acceptance of hydropower ? What are the specifications for home-installed water pipes? Let's take a look at what you need to pay attention to in the acceptance of hydropower !
1. What should be paid attention to in the acceptance of water and electricity
1. Perform pressure test on the new water pipe, and observe the overall effect of the water supply after the water supply; whether the water supply is smooth, whether there is a pipe crack, and whether there will be water leakage.
2. For the pipeline that the developer helped us install, I should seal it during construction to prevent foreign objects from entering the pipeline during the subsequent project.
3. The butt assembly of the outer diameter, corner, water meter and faucet of the water pipe should be good. In the installation and construction, a pipe clamp is set below the outer diameter of the water pipe 25mm and the pipe 100mm. The installation of the pipe clamp must be firm, so that the water pipe will not be bent due to the problem of water pressure.
4. Check the connection of all joints, valves and pipelines. These joints must be sealed to avoid leakage. When laying the pipeline, remember to give the pipeline a certain slope.
5. When constructing and installing the water pipe, keep away from the power supply and electric wires. Among them, the water pipe and the gas pipe are best not to be too close, the distance is recommended to be controlled above 50mm.
6. If the material is used for the water pipe, the editor recommends everyone here: if it is a sewer pipe, it is more suitable to use PVC pipes; if it is an inlet pipe, then it is more suitable to use PPR pipes; the choice of hot and cold water position, it is recommended that you not go Partial door, it is better to follow the rules of left hot and cold.
7. The trend of the electric wire tube is also very particular. â‘ Strong electricity walks the wall, weak electricity walks the ground; â‘¡ Both strong and weak electricity walks the ground, but must enter the pipe. These two trends will occur in the company of the city, and the strong and weak electricity will converge. It is recommended that the two should be separated by at least 300mm. Water pipe trend, don't go to the ground. It is better to go to the top, followed by the wall.
8. To strengthen the content of Article 7, in order to ensure the long-term use of the wire, the installation must be carried out through the tube, and there must not be exposed wires or connectors. And the strong and weak electricity should not be in the same tube. It is better to separate them separately and keep the tube loose.
9. In order to avoid leakage accidents, after the hydropower construction is completed, if the switch and socket have connectors, they must be wrapped with knotted tape.
Summary of the article: The above is what you need to pay attention to in the acceptance of hydropower and the entire content of the use of home improvement water pipes. Hydropower construction can be said to be one of the most important projects of house decoration. This step has not been installed, and the soft equipment at the back is well talked about, so everyone must let the supervision and acceptance!

High chlorinated Polyethylene Super - HCPE
Molecular Formula: [CH2-CHCl-CH2-CH2] n
EINECS No.: 208-407-7
CAS NO. : 63231-66-3
HCPE is a type of Chlorinated Polymer which contains chlorine at 65-69%. It is transparent, hard and brittle thermoplastic resins. It has high chemical stability, good salt water resistance and good ultraviolet resistance. It is readily soluble in organic solvents such as toluene, xylene and esters, forming a colorless to pale yellow, transparent solution. When this solution is applied to the surface of metal, concrete, paper etc., the solvent readily vaporizes at room temperature to leave a transparent, hard and lustrous glass-like film. This film resists the permeation of moisture and oxygen gas, and shows high resistance to various chemicals such as acids and alkalis. It protects the substrates from corrosion, and also serves as a top coating for decorative purposes.
HCPE can be used as gravure printing ink, the binder of heavy-duty anticorrosion paint, waterproof paint and the component of adhesives. Particularly, due to its high corrosive resistance to Cl-, it is especially suitable for being used on vessels, docks, containers coating. The paint made of HCPE can be used in chemical equipment, oil field pipelines, offshore facilities, ship coatings, metallurgy and mine, salt industry, fishing ground, wastes treatment, transportation facilities, container and electrical equipment. High molecular weight HCPE grades such as NVH -60 and NVH -120 are our unique products which are developed for all kinds adhesive for PVC pipe, pipe fittings, plates, sheets etc.
NV series are produced by our newly invented hydrochloric acid phase technology, in which no organic solvent such as carbon tetrachloride is involved, resulting no destruction to ozone layer and no harm to the operators health.
