Corrosion protection through hot-dip galvanisation • Pipe components described as “galvanised” are all hot-dip galvanised • Hot-dip galvanising to DIN EN ISO 1461 • Average layer thickness (minimum values) depends on the thickness of the steel: – <1.5 mm:
45 µm
– 1.5 mm to 3 mm: 55 µm – 3 mm to 6 mm: 70 µm
• Temperature-resistant to 200°C • During hot-dip galvanisation, irregularities may occur in the colour and structure of the surface
Corrosion protection through galvanisation • E.g. for pull-rings, air regulators, ball joints and other accessories • Galvanisation according to DIN 50979 Fe//Zn8//An//T0 colourless to iridescent colour • Layer thickness approx. 10 µm • Temperature-resistant to 120°C
