To prevent in-service cracking of new carbon steel equipment in five major projects in various stages of design and construction, an investigation into the factors believed related to the problem and an extensive weld hardness survey were conducted. Acceptable parameters of hardness and corrosivity of service were defined. Corrective action was taken depending on the hardness level, scope and location of hardness, economics of field vs shop work, etc. On stream experience with carbon steel welds in the first two units placed in service has been satisfactory.
