Technical Analysis and Application Guide for China Used Pipe Extruder JWell PE 90-250mm
I. Core Advantages
1.Corrosion resistance and chemical stability
PE pipes exhibit excellent corrosion resistance in acidic and alkaline environments (pH 2-12), and are particularly suitable for scenarios such as sulfur-containing wastewater and seawater desalination.
2. Impact resistance and seismic performance
PE100 grade pipes maintain good toughness within the temperature range of -20℃ to 60℃. After the 2022 earthquake in Turkey, the repair cost of the local PE water supply network was reduced by 65% compared to PVC pipes
3. Lightweight and construction convenience
Compared with concrete pipes of the same specification, the weight of PE pipes is reduced by more than 80%, significantly lowering construction energy consumption. In 2023, the Ministry of Housing and Urban-Rural Development's "Green Construction Technology Guidelines" listed it as a priority recommended material.
4. Long service life
The ISO 15663 standard certification shows that the service life of PE pipes under standard working conditions can reach more than 50 years, far exceeding that of galvanized steel pipes (20-30 years).
Ii. Scope of Application and Typical Application Scenarios
1. Municipal water supply system
Applicable diameter: 90-250mm
Technical requirements: It is necessary to meet the GB/T 13663-2021 standard, with a hydrostatic strength of ≥8.0MPa (PE100 grade).
2. Gas transmission and distribution network
Pressure grade: Medium pressure B grade (≤0.2MPa)
Safety standard: It is required to pass the GB 15558.1-2022 blasting test, with an elongation at break of ≥350%
3. Industrial fluid transportation
