H.D.P.E. Lining
Beton Bekaa Offers sewer pipes with HDPE (High density polyethylene) lining.
HDPE is a gas and watertight internal lining for sewage / effluent pipes. Successful results are ensured by HDPE both with new pipes and when reconstructing existing sewers.
HDPE lining offer high mechanical strength in combination with good chemical resistance. The well-designed studs, especially arranged, provide an integral bond between the plastic material and the concrete; hence providing perfect protection for ground water aganist pollution. Based on these outstanding properties, the system has proven its capabilities for many years under most severe operating conditions.
Beton Bekaa HDPE lining - the benefits:
- Welded system is gas and water tight
- Uniform mechanical bond between the HDPE inner tube and the concrete outer casing
- No differential expansion due to divergent expansion coefficients of concrete and plastics
- Sewer lined with HDPE are resistant to corrosion and chemicals as well as concentrated acids and alkalis as verified by the comprehensive resistance tests
- Long standing expertise with HDPE linings in acid - proof construction association with severe mechanical, thermal and chemical loads
- Smooth, anti-adhesive and low-friction internal tube surfaces enhance flow rate and reduce sludge accumulation and associated putrefaction processes with H2S formation
- Surface hostile to rodents
- Ease of repair
