Piling Pipes

Corrosion Control

The corrosion rate of steel pipe piles embedded in the ground is extremely low - approximately 0.014mm/year. About 2mm for corrosion thickness can therefor be assumed to be sufficient as an anti-corrosion measure for steel pipe piles. However, the rate of corrosion increases slightly for steel installed in sea water, especially in the splash zone.

Surface Preparation

Blasting, prepared to quality BS 4232 or other applicable standards.

Methods of Corrosion Control

  1. Painting - Zinc rich paint and coal tar epoxy, or epoxy resin paint.
  2. Organic coating - Epoxy resin mortar or polyethylene
  3. Metal spraying - Aluminium spraying
  4. Cathodic Protecting Method
