Abstract
A method of manufacturing a box header for an air-cooled heat exchanger. The method includes the steps of boring at least one hole into at least one end of an elongated slab of metal. Material from the slab is milled out adjacent to the at least one hole to form an elongated internal chamber in the slab having at least one open end. An inlet nozzle opening is machined into the elongated chamber and an outlet nozzle opening is machined into the elongated chamber. A plurality of tube holes and a plurality of plug holes are drilled and tapped in the elongated slab into the internal chamber. An end block is welded to the at least one open end in order to form a closed internal chamber.

A method of manufacturing a box header for an air-cooled heat exchanger, which method comprises the steps of:
- boring at least one hole into at least one end of an elongated solid slab of metal;
- milling out material from inside said solid slab adjacent to said at least one hole to form an elongated internal open chamber in said slab having at least one open end;
- machining at least one inlet nozzle opening into said elongated internal chamber and machining at least one outlet nozzle opening into said elongated internal chamber;
- drilling and tapping a plurality of tube holes and a plurality of access plug holes in said slab into said elongated internal open chamber;
- and
- welding an end block to said at least one open end in order to form a closed internal chamber.
