Standard Practice for Piping System Drawing Symbols

SIGNIFICANCE AND USE
2.1 Fig. 1 provides symbols for strainers, separators, and filters.  
2.2 Fig. 2 provides symbols for valves. Valves are categorized under the following headings: globe, angle, check, ball, butterfly, gate, relief, manifolds, control, noise control, and miscellaneous.  
2.3 Fig. 3 provides symbols for valve appendages such as actuators and locking devices. Symbols shown on Fig. 3 are to be combined with the appropriate symbol from Fig. 2.  
2.4 Fig. 4 provides symbols for piping system–related instrumentation. These symbols are categorized under the following headings: pressure, temperature, flow, level, switches, alarms, and miscellaneous.  
2.5 Fig. 5 provides symbols for fans, pumps, and turbines.  
2.6 Fig. 6 provides symbols for plumbing components.  
2.7 Fig. 7 provides symbols for pipe and pipe fittings.  
2.8 Fig. 8 provides symbols for noise control components and designations. These symbols are generally used for submarine design.  
2.9 Fig. 9 provides symbols for transitions. These symbols identify transitions such as pipe material or pipe schedule changes.  
2.10 Fig. 10 provides symbols for miscellaneous components. These are components which could not be classified under the above categories. Examples include heat exchangers, flasks, and sea chests.  
2.11 Fig. 11 provides symbols for grooved piping.
SCOPE
1.1 This practice establishes piping system drawing symbols for marine use.  
1.2 This set of standard symbols is intended for use on piping system diagrammatics and arrangements for ships.  
1.3 Where graphical symbols are required for an item or equipment not covered by this practice, the form and character of the symbol will be left to the discretion of the activity concerned, provided that the symbol used does not duplicate any of those contained herein, and is clearly understandable, subject to one interpretation only, or explained by a suitable note on the drawing when necessary.  
1.4 Since symbolic representation does not usually involve exact or scale layout or the actual run or leads of piping, the same symbol may be used for all projections of the system (plan, elevations, and sections).  
1.5 Symbols for fluid power, heating, ventilation, and air conditioning (HVAC), and Navy damage control diagrams are not included in this practice.  
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Overview

ASTM F1000-21, Standard Practice for Piping System Drawing Symbols, establishes a comprehensive set of standardized graphical symbols specifically for marine piping systems. Developed by ASTM International, this standard supports clarity and uniformity in shipbuilding and marine engineering drawings. By providing an internationally recognized set of symbols for components such as valves, instruments, fittings, and machinery, ASTM F1000-21 facilitates easier communication, documentation, and interpretation of piping diagrams across the marine industry.

Key Topics

1. Symbol Categories:

• Strainers, Separators, Filters: Symbols for various devices used to remove solids or separate fluids.
• Valves: Detailed symbols for globe, angle, check, ball, butterfly, gate, relief, manifold, control, noise control, and miscellaneous marine valves.
• Valve Appendages: Standardized representations for actuators, locking devices, and other attachments, to be combined with valve symbols.
• Instrumentation: Graphical symbols for pressure, temperature, flow, level measurement, switches, alarms, and other instrumentation related to piping systems.
• Mechanical Components: Symbols for fans, pumps, turbines, and related equipment used in marine piping.
• Plumbing Components: Representations of plumbing features found within shipboard piping networks.
• Pipe and Fittings: Standardized depiction of pipe sections, connectors, and fittings.
• Noise Control: Symbols often used in submarine or noise-critical marine applications for related components and designations.
• Transitions: Graphics detailing changes in pipe material, size, or schedule.
• Miscellaneous Components: Catch-all symbols including heat exchangers, flasks, sea chests, and other non-categorized elements.
• Grooved Piping: Standard icons representing grooved piping systems.

2. Application Guidelines:

• Symbols are intended for all projections (plan, elevation, section) and do not require exact scale layouts.
• For items not covered, supplemental clearly-understood symbols may be used, provided they do not duplicate existing ones and are explained as necessary.

3. Exclusions:

• Fluid power, HVAC, and Navy damage control diagrams are not included.

Applications

ASTM F1000-21 is predominantly used for:

• Marine Shipbuilding and Engineering: Simplifies design by ensuring that engineers, designers, and contractors use a shared language when creating piping system diagrammatics and arrangements for ships.
• Project Documentation: Enhances the accuracy and clarity of technical drawings, contributing to efficient project execution, maintenance, and regulatory review.
• Standardized Training: Offers a reliable reference for training marine engineers, draftsmen, and quality inspectors in interpreting piping diagrams.
• International Projects: Its international status ensures uniformity in multinational projects, aiding global compliance and communication.

By adopting ASTM F1000-21, organizations can reduce misinterpretation, improve drawing efficiency, and maintain consistency in technical documentation for marine piping systems.
