Detail Section Drawing of Jacketed Double Pipe Heat Exchanger

This AutoCAD DWG drawing presents a detailed sectional representation of a jacketed type double pipe heat exchanger, clearly illustrating the construction and assembly of individual components. The drawing includes plan, elevation, sectional views, and enlarged detail views of elbows, reducers, nozzles, flanges, stub ends, and lifting lugs. Nominal pipe sizes such as 300 NB, 350 NB, and 400 NB are shown with precise dimensional annotations, along with slope indications of 7.5 degrees and 0.75 degrees for proper flow and drainage. Material specifications like SS 316 and fabrication details such as welding joints, bolt hole pitch, circle diameters, and flange thicknesses are clearly marked to support accurate manufacturing and installation.

The DWG file also highlights jacketed pipe arrangements, inlet and outlet nozzle positions, elbow curvature details, and section references for clarity. Individual part details include end closures, stub ends, reducers, and lifting lug dimensions with thickness values for safe handling. This drawing is suitable for understanding heat exchanger geometry, coordination with piping layouts, and preparing shop or fabrication drawings. The level of detailing makes it useful for design validation, construction reference, and technical documentation in industrial and mechanical projects requiring jacketed double pipe heat exchanger systems.
