News - The Advantages of Large Diameter PE Pipe Fittings

1. Light weight, convenient transportation, simple construction: galvanized steel pipe has strong construction strength, often need auxiliary construction tools such as cranes; The density of PE water supply pipe is less than 1/8 of the steel pipe, the density of 0.935g /&#;3 galvanized steel pipe is 7.88g /&#;3, the construction strength is low, and the construction progress is fast.

2. Corrosion resistance: After the temporary use of galvanized steel pipe, the zinc layer is simply destroyed, resulting in corrosion of the steel pipe. The service life of galvanized steel pipe is about 10 years. PE water supply pipe has good chemical stability and excellent corrosion resistance. Sex, which does not react chemically with other elements in water, has a service life of up to 50 years.

3.Easy connection, simple installation: galvanized steel pipe should not be welded. When the flange welding needs to be connected to a single connecting part, the galvanized layer damaged by welding needs to be treated with corrosion protection; PE water supply pipe adopts hot melt connection. It is convenient and fast, greatly reduces the difficulty of construction, and jointly shortens the construction period.

4. Long service life: the service life of galvanized steel pipe is only about 20-30 years, while PE pipe can withstand the erosion of various chemical media, and the service life of up to 50 years under normal working conditions, which is in line with our current building life rules.

5. Inner wall is smooth, the water yield is large, and the operation energy consumption is small: the roughness n value of PE tube is only 0.008. The roughness rate of the new galvanized steel pipe is 0.025, and the roughness value will increase 510 times after 20 years of operation. PE water supply because the pipe is non-corrosive, so its roughness does not change with time. Under the same pipe diameter and the same water pressure, the resistance loss along the way can be reduced by 30%. The water transfer capacity is much better than galvanized steel pipe, and can last 50 years. No major changes.

6. Easy maintenance and low maintenance cost: large-caliber PE pipe fittings are easy to repair, can be repaired and installed without water interruption, and do not need expensive and messy things. According to actual engineering experience, the maintenance cost of PE pipes is only 30% of the galvanized steel pipe.

7. Good wear resistance: The wear resistance of PE water pipe is more than 4 times that of galvanized steel pipe.

8. Good low temperature resistance: the low temperature embrittlement temperature of PE water supply pipe is very low, and it can be used safely in the temperature range of -20-40 ° C. During winter construction, the pipe brittleness will not occur due to the good impact resistance of the material.

9.Good resistance and flexibility: the construction of galvanized steel pipe has higher requirements for pipe foundation and poor adaptability; PE pipe is a high strength pipe, its elongation at break is more than 500%, which may lead to uneven foundation settlement and dislocation. It&#;s very adaptable. The flexibility of other PE pipes allows P large diameter pe pipe fittings to be coiled, especially for small diameter pe pipe fittings, which reduces a lot of receiving parts. During the construction process, obstacles can be bypassed within the zigzag radius of the allowable scale of the pipeline to reduce the difficulty of construction.

10. Good air tightness: The large diameter pe pipe fittings are connected by hot melt, which essentially ensures the identity of the interface material structure and the pipe body itself, and completes the integration of the joint and the pipe.
