Comparison of PE pipe and steel pipe
1. Lightweight, convenient transportation, and low construction cost: The seamless steel pipe has high construction strength and often requires auxiliary construction tools such as cranes. The density of PE water supply pipes is less than 1/8 of that of steel pipes (PE water supply pipes have a density of 0.935g/㎝3, steel pipes). It is 7.88 g/㎝3), the 315-size pipe weighs only 9.29kg, the construction intensity is low, the progress is fast, and the construction cost can be reduced by 30%-50% compared with traditional pipes; and with the shortage of steel in the market, its The price will continue to rise, so it's cost performance is self-evident compared with PE water supply pipes. 2. Corrosion resistance: The outer side of the steel pipe needs to be brushed with oil to prevent corrosion, which increases the project cost; the inner side of the steel pipe is susceptible to electrochemical corrosion and microbial corrosion and must be anti-corrosive. After long-term use, the zin...
