The strength and stiffness of low-pressure underground sewage and PVC-UH pipes for drainage are improved, and the bearing capacity of the system is maximized within a certain budget.
1. Do not be affected by sewer acid and alkali, and avoid alkali and acid corrosion of soil.
2. Stable performance, can effectively prevent corrosion and adapt to external current soil conditions, without lining packaging, coating and cathodic protection.
3. Wear resistance, tensile resistance and impact resistance are much better than common pipeline materials.
4. Smooth inside of the pipe for a long time, while maximizing the capacity of the system, can save pumping costs.
5. Light weight could save installation cost. Cutting can be done in the site with a electric saw or ordinary hand saw, without using expensive or complicated machinery.
6. Ring lock washer insider of the pipes, which eliminates the requirement of welding for old PVC drainage pipes in site.
7. Elastic gaskets provide excellent sealing and protect the entire section from impact, vibration, soil movement, expansion and contraction in deep trenches.
8. Simple push-in connections provide quick and easy installation without the need for on-site mixing and the use of cement.
The connection shall be well sealed under normal working conditions.
