Industrial-grade PE100 Pipes For Seawater Desalination Revolution
Three Generations of Polyethylene Pipe Evolution Milestone
PE80 era (1980s) : Breakthrough in creep resistance, but insufficient resistance to environmental stress cracking
PE100 was born (1990s) : The bimodal molecular structure made MRS (minimum required strength) jump to 10MPa
PE100+RC (2020s) : Resistance to rapid crack growth increased by 300%, suitable for extreme working conditions
Molecular structure microscope comparison diagram:
PE80: single peak type molecular chain, easy to form stress concentration points
PE100: Long and short chain bimodal distribution, to build a three-dimensional network damage resistance structure
Benchmark of industrial performance parameters
| Key indicators | PE100 standard value | Conventional steel pipe comparison |
| Design life | 50 years + | 15-20 years |
| Chemical resistance rating | ANSI/NSF 61 certified | Additional anti-corrosion coating required |
| Installation efficiency | 200 m/day (hot melt) | 50 m/day (welding) |
| Recycling carbon footprint | 0.8 mt CO2e/ t | 2.3 tons CO2e/ ton |
4 Core Strengths: Engineering Dominance Of The Pivot Table PE100
Deep-sea high-pressure Conqueror
-Measurement of 2,450 meters underwater pipeline in the Norwegian North Sea: DN1200 pipe has operated for 7 years with zero leakage at 15MPa pressure
– resistance to external pressure formula: \ (P_ (cr} = \ frac {2} e {1 – \ nu ^ 2} \ left (\ frac {t} {D} \ right) ^ 3 \)
(E= elastic modulus 900MPa, ν= Poisson’s ratio 0.45)
Chemically corroding immune bodies
The annual corrosion rate of -10% sulfuric acid environment is 0.005mm, which is only 1/100 of stainless steel pipe
– Exclusive three-layer co-extrusion process (UV/ permeability/wear resistance) extends the life to 2.3 times that of traditional PE pipes
Extreme temperature adaptor
-50℃ impact strength retention rate > 90%, Russia Yamal project -56℃ verification
-120 ℃ Vica softening point, Saudi high temperature seawater desalination project for 5 consecutive years of stable operation
Earthquake disaster defense network
3% axial deformation without damage, the integrity rate of PE100 pipeline network in Kobe, Japan is 100%
The elastic modulus is 0.8GPa, which is 8 times higher than the energy absorption capacity of the steel pipe
Six gold application scenarios and seawater desalination depth analysis
PE 100 Pipes for Seawater Desalination
Triple compound challenge:
45,000ppm ultra high salinity ➜ Three layer co-extrusion anticorrosive construction
55℃ continuous high temperature ➜ nanometer zinc oxide heat stabilizer
Dynamic load in tidal area ➜ ANSYS optimized span design
Performance data comparison:
| Metrics | Original stainless steel tube | PE100 pipe | Lift amplitude |
| Annual maintenance cost | $3.8 million | $1.25 million | 67% left |
| Leakage accident rate | 3 times/year | 0 times /5 years | 100% left |
| Energy intensity | 4.7 kWh/m after | 3.8 kWh/m after | 19% left |
Other Top 5 Cutting-edge Applications
1. Deep sea oil and gas delivery: The DN560 pipeline in Australia’s North West Shelf set a water depth record of 2,450 meters
2. Hydrogen energy pipeline network: the EVOH permeability layer achieves hydrogen permeability < 0.5ml/(m²·day)
3. Polar LNG transport: -162℃ impact strength maintained 80kJ/m², Qatar project verification
4. Smart water system: Renovation of water plant in Munich, Germany, reduces leakage rate to 3.7%
5. Transportation of mine tailings: basalt reinforcement layer makes the life of steel pipe three times
