Abstract:
A method for protecting a welded pipe assembly from metal dusting and a welded pipe assembly suitable for performing the method. The welded pipe assembly comprises two pipes, weld material joining the two pipes and insulating material. The pipes are protected from metal dusting by a protective coating. The present invention is useful for conveying gases comprising carbon monoxide at temperatures greater than 425° C. while preventing metal dusting of the welded piping assembly.
