Planning a Similar Build

Plan around the connections: mark flange patterns, mating equipment, flow direction, and the dimensions that must match the installation. A delivery package also needs defined shipping splits and a way to identify each section on site.

A similar need: New or replacement ductwork with defined field connections and shipping splits.

What to send: Drawings, material, thickness, connections, coating, and delivery or installation scope.

Large tank fabrication and handling

An Ahner tank secured for transport. Handling and shipping matter alongside fabrication.

Plan the vessel and the move together. Provide the released design, nozzle and support details, inspection requirements, shipping envelope, and receiving access. Confirm the design authority and any pressure or code scope before fabrication is accepted.

A similar need: Tank components and heavy weldments needing forming, welding, and a delivery plan.

What to send: Released design, material, welds, inspection, operating conditions, and shipping plan. Code or pressure requirements need project-specific review.

Welded plate and structural assembly

Ahner platework and structural supports built into one assembly.

Define the assembly interfaces before individual pieces are cut. Mark mounting datums, mating components, required loads, and customer-defined acceptance dimensions; identify finish and any surfaces that must remain uncoated.

A similar need: Hoppers, chutes, and equipment supports combining platework and structural fabrication.

What to send: Drawings or a sketch, mounting interfaces, materials, loads, finish, and scope.
