- Introduction
Analysis of the core content of the standard
Technical parameters PE80 requirements PE100 requirements Test methods Long-term static hydraulic strength (20℃, 50 years) ≥8.0MPa ≥10.0MPa GB/T 18252 Slow crack growth resistance time ≥500h ≥500h GB/T 18476 Carbon black content (black pipe) 2.0%-2.5% GB/T 13021
Key Technology Upgrade
Compared with the 2003 version of the standard, the 2015 version has the following major improvements:
- The slow crack growth resistance index has been increased from 165h to 500h
- New Compression recovery test requirements (Appendix F)
- Added high crack resistance PE100 material specifications (Appendix D)
- Pipe color identification system optimization (orange PE100 exclusive)
Implementation Suggestions
Key points for design selection:
- SDR11/SDR17 are commonly used pressure levels
- SDR21/SDR26 pipes are preferred for trenchless construction
- Artificial gas transportation requires special consideration of medium corrosiveness
Key to quality control:
- Focus on 80℃/165h hydrostatic test
- Welding compatibility verification cannot be ignored
- Carbon black dispersion must be ≤ level 3
