Completed Project on ‘Best Practices for Welding P91 to P91 and P91 to P22 Steels’.

ETD Consulting have recently completed a project on ‘Best Practices for Welding P91 to P91 and P91 to P22 Steels’.

There was an urgent need to weld a new P22 boiler stop valve into a P91 main-steam line, which had been in operation for more than 100,000 hours. ETD was approached by a client for guidance on the current best practices for welding P91 to P91 and P91 to P22 steels. Based on its experience and knowhow, ETD provided a summary of the best practices and guidelines for this critical welding application.
