Features of HDPE sewer pipes for trenchless installation:
1. Excellent flexibility and strong toughness;
2. Anti abrasive, anti-aging, uvioresistant, corrosion resistant, long service life;
3. No breaking, no dripping, good velocity of flow to ensure the high transportation efficiency;
4. Better resistance to concussion capability than steel pipes;
