Standard size than SDR17.6 φ20 ~ φ630 0.2MPa
Standard size than the SDR11 φ20 ~ φ630 0.4MPa
What is the maximum allowable working pressure of the two series?
In the case of 20 ℃, SDR11 series maximum allowable working pressure is 0.4MPa, SDR17.6 series maximum allowable working pressure is 0.2MPa.
1) high strength, good resistance to stress cracking performance, good creep resistance;
2) toughness, flexibility, and the uneven foundation of the ability to adapt to dislocation, can withstand earthquakes and typhoons and other harsh environments;
3) has good weather resistance (including UV) and long-term thermal stability;
4) corrosion resistance, long service life, suitable for conveying natural gas, liquefied petroleum gas and gas;
5) smooth inner wall, large circulation capacity, gas flow rate can reach 20m / s, saving operating costs;
6) good wear resistance, wear resistance;
7) low-temperature impact resistance, and can be -20-40 degrees in the temperature range of safe use, winter construction is not affected;
8) hot melt (or fused) connection convenient and reliable, construction and maintenance is simple (during which can not stop gas);
9) fully suitable for traditional excavation construction methods and pipe jacking, directional drilling, liner, pipe cracking, submerged underwater and other new trenchless technology;
10) polyethylene raw materials contain only carbon and hydrogen two elements, environmentally friendly, green.
