PE water supply pipe construction plan
PE water supply pipe construction planPE water supply pipes and fittings are produced with PE100 or PE80 as raw materials. The specifications, dimensions and performance meet the requirements of enterprise standards. The sanitary performance meets the engineering standards and the relevant safety evaluation regulations of the Ministry of Health of the company. Good, strong corrosion resistance, light weight, excellent impact resistance and other advantages. Pipes and fittings can be connected by hot-melt socket, hot-melt butt joint, and electric fusion. The pipes and fittings are integrated, the system is safe and reliable, the construction cost is low, and it has developed rapidly in engineering applications. Vigorously promote PE pipes, in line with the guidelines of the Ministry of Construction and the State Economic and Trade Commission for the development of chemical building materials, and meet the development needs of people's living standards.
Features 1. Long service life: Under normal conditions, the life expectancy is less than 50 years. 2. Good hygiene: PE pipes are non-toxic, do not contain heavy metal additives, do not scale, do not breed bacteria, and solve the problem of secondary pollution of drinking water. Comply with safety evaluation standards and relevant health safety evaluation regulations of the Ministry of Health. 3. Corrosion resistance of various chemical media: no electrochemical corrosion. 4. The inner wall is smooth, the friction coefficient is extremely low, the passing capacity of the medium is correspondingly improved and it has excellent wear resistance. 5. Good flexibility, high impact strength, strong shock resistance and distortion. 6. Light weight, convenient transportation and installation. 7. The unique electric fusion connection and hot fusion butt connection and hot fusion socket connection technology make the interface strength high and the pipe body, ensuring the safety and reliability of the interface.
8. The welding process is simple, the construction is convenient, and the overall project cost is low.
9. PE environmental protection and health water supply pipes dn25 ~ dn90 are black, above dn110 are blue or black with blue line, other colors need to be customized, and the color of accessories corresponds to the color of the pipe. When using this method for hot melt docking,
Using hot melt welding machine, the specific steps are as follows:
1. Prepare the necessary tools.
2. Put the pipe to be connected to the fixture of the welding machine and clamp it. At the end of the pipe to be connected and mill the connecting surface, straighten the two butt joints so that the misalignment is not more than 10% of the wall thickness.
3. Put in the heating plate.
4. After heating, take out the heating plate, quickly join the two heating surfaces, boost to the welding pressure and keep the pressure to cool.
5. Hot melt is completed.
2. The characteristics of electrofusion connection are that the connection is easy and fast, and the interference of external factors is small. It is more economical to apply in the case of small-diameter pipes and difficult construction. The connection steps are as follows: 1. Plot pipe to be connected On the dirt, mark the insertion depth. 2. Scrape its skin. 3. Put the electric fusion pipe fitting on the pipe material, and ensure that the pipe is straightened on the same axis. 4. Welding after power-on, wait for the melt out of the signal eye. 5. Cool and complete the electric melting. Matters needing attention 1. When connecting, the voltage and heating time when electrified and heated should be in accordance with the regulations of the manufacturer of the electrofusion connection tool. 2. During the cooling of the electrofusion connection, it is not allowed to move the connection piece or exert any external force on the connection piece。
