Reheater Repair and Refurbish
Challenge
APComPower (Alstom) was awarded a contract to repair and refurbish a reheater at the Mt. Storm Power Station, involving welding old tube material to new, with tight clearances between boiler tubes. Mt. Storm is the largest coal-fired plant managed by Dominion and generates 1,600 MW.
Solution
The low-profile D-Head made the multipass 2G welds, easily handling the tight radial clearance. All welds met radiographic inspection.
