Rule of Thumb

30" diameter pipe = 30 running meter Wrappingband CZH 100x10
24" diameter pipe = 24 running meter Wrappingband CZH 100x10

Overlap
Minimum overlap for all sizes of Wrappingband: 10%
Minimum overlap for all sizes of Outerwrap: 50%

Example for Wrappingband CZH:
Diameter pipe: 24 inch
Corrosion Prevention product: Wrappingband CZH 100x10 (1m2)
Overlap = 15% for CZH
Practical consumption CZH = 12 running meter/m2
1 running meter requires ( 24 x 0,0254) x Pi 3,14 x 12 = 23 running meter
