Cangzhou PE gas pipe is a traditional steel Pipe Polychlorine ethylene Replacement products of gas. The gas pipe must bear a certain pressure, usually with large molecular weight and mechanical properties http://www.hdpeguancai.com/ Good PE resin, such as HDPE Resin, the following are Performance requirements of PE gas pipe.
1. Hydrostatic strength (Hs) requirement: destruction time ≥ 100h
2. Requirements for elongation at break: ≥ 350
3. Weather resistance (only applicable to non black pipes) requirements: after weathering, the following properties meet the required stability HS (65h/80 ℃) elongation at break. http://www.peguangaiguan.com/
4. Full size (FS) test: dn ≥ 250mm or S4 test is applicable to all diameters
Requirement: critical pressure for full-scale test (Mpa) PC , FS ≥ 1.5 × critical pressure of MOP S4 test PC, S4 ≥ MOP/2.4-0.072
5. Resistance to slow crack growth en>5mm Requirement: 165h
6. A Requirements for thermal stability (oxidation induction period):>20min
7. Requirements for longitudinal retraction rate: ≤ 3%
8. Melt mass flow rate (MFR)
