- Basic types of symbols used in engineering drawings are countersink, counterbore, spotface, depth, radius, and diameter. Here are more commonly used engineering drawing symbols and design elements as below. You can also check out the GD&T symbols and terms on our site.
- 1.2 STATE how the grid system on an engineering drawing is used to locate a piece of equipment. 1.3 STATE the three types of information provided in the revision block of an engineering drawing. 1.4 STATE the purpose of the notes and legend section of an engineering drawing. 1.5 LIST the five drawing categories used on engineering drawings.
Process flow diagrams use special shapes to represent different types of equipments, valves, instruments and piping flow. Edraw provides plenty of PFD symbols and helps you create process flow diagrams easily and quickly.
Edraw includes standard sets of symbols depicting mechanical equipment, piping, piping components, valves, equipment drivers, instrumentation, and controls. These PFD symbols are assembled on the drawing in a manner that clearly defines the process flow diagrams. With the pre-made PFD symbols in Edraw Max, you can make a process flow diagram in minutes!
Part 1: Process Flow Diagram Symbols - Equipment
Pumps and tanks come in a variety of designs and shapes.
Compressor is a mechanical device that takes in a medium and compresses it to a smaller volume. A mechanical or electrical drive is typically connected to a pump that is used to compress the medium.
Pump refers to a mechanical apparatus using suction or pressure to raise or move liquids, compress gases, or force air into inflatable objects such as tires. The symbols for pumps may closely resemble those for compressors.
Mixing is a gear that combines some materials or put them together to form one substance or mass.
Mixing vessel is a container that is used to blend several components.
Heat exchanger is used to transfer heat energy between two process flows. Heat exchangers transfer heat energy through conductive and convective heat transfer.
Cooling towers transfer heat energy to the outside air through the principle of evaporation.
Cooler is a device, container, or room that cools air through the evaporation of water or keeps cool.
Furnace means a tool for heating a continuous current of air through a fire within the apparatus and without mingling the fresh air with the products of combustion.
Boiler is a closed vessel in which water or other fluid is heated.
Tank is used to store process fluids of various types under different process conditions.
Gate valve is a device used to control the flow of liquids and gases.
Check valve, also known as a one-way valve, is to prevent the line of medium back.
Globe valve refers to a mechanism used to control or stop liquid or gas flow through a pipe.
Ball valve is a valve with a spherical disc, the part of the valve which controls the flow through it.
Butterfly valve is installed between two flanges using a separate set of bolts for each flange.

Angle valve is oriented at a 90 deg angle of the gate valve.
Part 3: Process Flow Diagram Symbols - Piping Lines
Mechanical Engineering Drawing Symbols And Their Meanings
Process flow diagrams use special piping lines to represent how signals are transmitted between equipments. These symbols are used to identify how the instruments in the process connect to each other. And what type of signal is being used. (electrical, pneumatic, data, etc)
All lines are fine in relation to process piping lines.
Major pipeline is for the connection of the equipment in any position.
Major Straight line issued to connect the equipment in the same horizontal or vertical position.
