Excellent compression performance<br \/>\n<\/span><span style=\"font-size: 16px;\">Outer wall corrugated design: enhanced ring stiffness (SN8-SN12.5), high compressive strength, suitable for different burial depth requirements.<br \/>\n<\/span><span style=\"font-size: 16px;\">High toughness HDPE material \u00a0: good flexibility, impact resistance, not easy to break, suitable for foundation settlement.<br \/>\n<\/span><span style=\"font-size: 16px;\">2. Super corrosion resistance<br \/>\n<\/span><span style=\"font-size: 16px;\">Acid and alkali resistance, anti-aging: HDPE material is not corroded by chemicals, sewage, and soil, and has a long service life.<br \/>\n<\/span><span style=\"font-size: 16px;\">Anti-scaling \u00a0: The inner wall is smooth, the friction coefficient is low, the long-term use is not easy to accumulate scale, and the drainage efficiency is higher.<br \/>\n<\/span><span style=\"font-size: 16px;\">3. Light and easy to construct<br \/>\n<\/span><span style=\"font-size: 16px;\">The weight is only 1\/10 of the cement pipe, convenient for transportation and handling, greatly reducing the construction cost.<br \/>\n<\/span><span style=\"font-size: 16px;\">Flexible connection method: It can be connected by a socket rubber ring, has fast installation, and shortens the construction period by 30%.<br \/>\n<\/span><span style=\"font-size: 16px;\">4.
