Corrugated Liner Plate provides corrugations extending through the lapped longitudinal joint. When assembled, this liner functions as a corrugated pipe with continuous circumferential corrugations. The result is more effective corrugation performance for the highest stiffness and strength in the industry!
Corrugated Liner Plate provides corrugations extending through the lapped longitudinal joint. When assembled, this liner functions as a corrugated pipe with continuous circumferential corrugations. The result is more effective corrugation performance for the highest stiffness and strength in the industry! Strength to handle the inconsistencies encountered on a regular basis. Extra safety factor when you need it most!
The minimum allowable depth of cover is the largest of:
For roads H=B/8+0.2(m) H=B/6(m) and not less than 0.6（m）
For railways H=B/4 and not less than 0.6(m)
There is a possibility to reduce depth of cover provided that suitable checking calculations will be made.
| Flexible structure | Plate thickness | Kinds of standard corrosion protection | Required average min value(um） |

| ≧3mm do < 6mm | Hot zinc galvanizing | 70 | |
| ≧1.5mm do < 3mm | Hot zinc galvanizing | 55 | |
