With regard to the type of design, a corrugated and spiral double-wall pipe has high Newtonian resistance. This type of pipe includes 16, 31.5 and 64 kilo Newton pressures and may be installed on sea water, in trenches, and underground. Double-wall pipes are used for collecting urban sewage disposal, surface water, fluid transfer, agricultural and drainage purposes.
Application of spiral pipes:
1. Construction of polyethylene bridges
2. Transfer of water and sewage fluids
3. Transfer of acids and bases
Concerning installation conditions, calculation method, and flexibility, polyethylene bridges are more important than steel concrete bridges.
Application of double wall PE :
1. Railway
2. Special roads
3. Main roads and highways
4. Temporary bridges
