GB 6567.1-1986 is the national standard for graphical symbols for pipe systems. It establishes the basic principles for the design, specification, and use of graphical symbols for piping systems.
The standard defines four elements of graphical symbols, which are shape, color, size, and arrangement. Shape is used to represent the type and arrangement of piping components and their components. Color is used to distinguish between materials, fluids, and systems. Size is used to denote the diameter of pipes and other components. Lastly, arrangement is used to indicate the guidance and direction of flow of the fluids being carried through the system.
The standard divides pipe systems into general categories, and each category has detailed drawing requirements for its components. These sections include general requirements, pipe and fittings, valves, auxiliaries, mechanical equipment, special symbols and symbols for general piping installations.
In the general requirements section, the standard outlines the principles for general piping drawings, such as size, scale and orientation. It also provides general guidelines for labeling, identification and documentation.
The pipe and fittings section describes various types and sizes of pipes, pipe fittings, and components. Commonly used pipe materials and relevant pipe diameters are also included.
The valve section specifies the various types of valves and their respective symbols. It also describes the working conditions, materials and sizes of various valves.
The auxiliaries section provides graphical symbols for various auxiliary equipment such as pumps, compressors, filters, heat exchangers, and dampers. Special symbols for general piping installations, such as those for welding and clamping, are also included.
GB 6567.1-1986 also describes the organization system and labeling of the components in a pipe system. It outlines the necessary symbols and signs for easy identification and understanding of the system.
The national standard of graphical symbols for pipe systems is very important in the engineering world. It facilitates communication among engineers to convey the design of the pipe system quickly and accurately. This uniform system of graphical symbols helps to avoid misunderstandings among engineers and other related personnel, ensuring the proper operation of any piping system.
