Krah Pipe Feature
- 1.Krah Pipes are made of high-density polyethylene (HDPE) that meets national environmental protection standards. They are pollution-free during the production process and are 100% recyclable.
- 2. Krah Pipes offer excellent flexibility and seismic resistance, withstanding earthquakes and ground subsidence, minimizing damage and improving disaster resistance.
- 3. The inner wall of the structural wall HDPE pipe is smooth, with low friction and strong flow capacity. The pipe is wear-resistant, aging-resistant, and chemically stable, with a service life of more than 50 years.
- 4. The connection is safe and leak-free, and the weight is easy to install.
Krah Pipe Application
- 1. Municipal Engineering: Krah Pipe is used forurban drainage, sewage, and rainwater collection systems.
- 2. Complex Geology: high-density polyethylene structured wall pipes are used in high-load roads, railway culverts, and subsidence areas.
- 3. Environmental Protection: HDPE Krah Pipes are used for sewage treatment plants and landfill drainage pipelines.
- 4. Water Conservancy: HDPE Krah Pipes are used in agricultural irrigation and reservoir water pipelines.
