HDPE Winding Structure-wall Pipe (Krah Pipe)
Krah pipes are hot-wound high-density polyethylene structure-wall pipes. Type B HDPE winding structure-wall pipes use HDPE resin as the main material and a hot winding process, with PP single-wall corrugated pipe as the supporting structure, producing a special structure-wall pipe with high external pressure resistance.

Features
- Raw material meets national environmental requirements; the production process is pollution-free and 100% recyclable.
- Hot winding on steel moulds produces high-quality fusion seams.
- Excellent flexibility: minimises damage from earthquakes and uneven ground settlement, improving seismic resilience of public facilities.
- Proprietary socket-type electrofusion jointing technology with zero leakage ensures safe system operation.
- Complete accessories: matching fittings and inspection wells allow a full pipeline system.
- Superior drainage performance: smooth inner wall, low friction, high flow velocity and large capacity.
- Corrosion and ageing resistant: chemically stable, requires no anti-corrosion treatment, withstands acids and alkalis, with a service life over 50 years.
- Lightweight: a fraction of the weight of concrete or steel pipes under the same conditions, making installation faster and easier.
Applications
- Municipal drainage networks
- Stormwater and sewage separation projects
- Underground utility tunnels and inspection wells
