Herr & Sacco Was Contracted to Design and Build an Air Separation Column Box

Herr & Sacco Inc. is a customer-focused mechanical contracting organization offering services from metal fabrication to process piping and rigging. The project highlighted here was a structural frame designed for use in the air separation industry that required both stainless steel and aluminum welding. With an ability to provide high purity welding within confined spaces, Herr & Sacco fabricated the structural frame and enclosed it in steel plates, as well as filled it with heat exchangers, vessels, separators, and miles of aluminum pipe. The complex project was completed with the use of a plate shear, plate roll; marvel saw, MIG welders, and 20-ton bridge cranes. The product was composed of a carbon steel and stainless steel structure with aluminum pipe. It featured dimensions of 12.5" long, 14" wide, 100’ in height, and with a tightest tolerance of ±0.003". Dimensional integrity was confirmed with the use of dye penetrant, high pressure testing, and radiographs. The project represents a run of one piece delivered in ten months.
