Annealing Line Installation

This project involved full–scope, heavy–duty process work, including: demolition and replacement of foundations and entry/exit terminal equipment (including accumulators), removal and replacement of existing strip furnace refractory and all associated piping and electrical work. Large piping components were prefabricated prior to installation and structural steel was assembled on the ground as much as possible. In addition, the Graycor team constructed a new shot–blast machine with baghouse, replacde two existing pickle tanks and installed both strip–oiling and acid–chilling equipment.

Graycor also upgraded the plant′s main substation and performed a majority of the piping work for a new process hydraulic system, as well as a proprietary furnace gases piping system and polypropylene lined pipe for the acid system.

Over the scope of the project, Graycor self–performed concrete, structural steel and mechanical work, with pipefitting work accounting for approximately 25 percent of the overall man–hours. Graycor Industrial′s construction strategy included a large amount of modularization, which positively impacted the schedule. Craftsmen worked two 10–hour shifts, six days per week, to complete everything within its aggressive timeline.
