New coating aids AUMA corrosion protection

23/01/2012

AUMA recognises that corrosion protection is an essential and integral part of its product offer. For over thirty years offshore applications have been supplied with the company’s robust valve automation technology and device capability has been enhanced with a new two-layer powder coating process. Single housing parts of AUMA’s modular electric actuators are now coated prior to assembly: this ensures that, whenever the housing is opened for installation, commissioning or other procedures, there is no increased risk of corrosion.

The initiative from AUMA protects individual elements of the housing and represents a paradigm shift for the global actuator supplier. Previously, a finish coating was applied after final device assembly. The new process incorporates a first layer for optimum adhesion of the finish coating and a second layer which ensures resistance to chemicals/ the weather and mechanical impact.

Commenting on the advancement in actuation, AUMA joint Managing Director Henrik Newerla advised that this is a significant breakthrough that marks a revolutionary production change for AUMA - the new procedure has required design modification of the company’s components and this has had a major impact on the organisation’s manufacturing process. AUMA complies with EN ISO 12944-2, a standard that supports the end user and offers a solid basis for specifying corrosion protection requirements for applications.
