Polyethylene corrugated pipe• A protector for electric power lines laid underground from power plant to each facility such as a plant, a substation, and a transformer. The main material is High Density Polyethylene (HDPE).
- Easy underground installation for HDPE's great flexibility and high flattening strength
- Inserted lead-in purpose wire making it easy to insert cables
- Wave-form pipes as a great solution to flattening solidity issues from existing straight polyethylene pipes
- Superior compressive strength light weight & long unit length excellent safety with minimum connection economy with enhanced work efficiency & shortened construction period
| Features
Flexible
Simply bend pipes to detour obstacles. It will make construction much easier.
Safe from ground subsidence
Excellent compressive strength ensures great pipe durability even in case of ground subsidence.
Easy to insert
Inserted wires uphold workefficiency.
Durability from compressive strength
Thick waves support compress strength and the durability helps maintain theform.
Long unit length & light weight
Light weight pipes are easily movable; long unit length can save time and manpower for connecting each pipe line.
