Free AutoCAD process equipment symbols (DWG): vessels, reactors, columns, exchangers, pumps — pictorial views

Process equipment symbols (pictorial views): 158 ready-made AutoCAD blocks (DWG), free to download and use in your own projects, as a ZIP or one symbol at a time.

158 process equipment outlines as ready-to-use AutoCAD blocks for process flow diagrams and P&IDs: vertical and horizontal vessels, spheres and storage tanks, agitated reactors, fixed bed and fluidised bed reactors, trayed and packed columns, shell and tube, plate and air cooled exchangers, fired heaters, centrifugal, gear, screw and reciprocating pumps, compressors, fans and turbines, crushers, mills, screens and conveyors, cyclones and dust collectors, filters and centrifuges, PSA adsorbers, cold boxes, electrolysers, cryogenic tanks, freeze dryers, isolators and blenders. Each block carries a tag and invisible equipment list attributes. This is the pictorial edition: each machine is drawn the way it looks, with flanged nozzles, casings, drives, supports and internals. The schematic edition of the same equipment, in the simple outline style of flow diagrams, is a separate library.
