ASTM F1199-21 PDF

Overview

ASTM F1199-21 is the internationally recognized standard specification for cast and welded pipe line strainers designed for use at pressures up to 150 psig (1 MPa) and temperatures up to 150°F (65°C). Developed by ASTM Committee F25 on Ships and Marine Technology, this standard sets forth the minimum requirements for the design, fabrication, rating, marking, and testing of strainers used to remove solid contaminants from liquids and gases in piping systems. ASTM F1199-21 is especially relevant for applications in marine environments, supporting reliable operation and equipment protection.

Key Topics

• Scope of Use: Applies to both cast and fabricated (welded) strainers for services not exceeding 150 psig and 150°F. For operations above these limits, see ASTM F1200.

• Categories of Strainers:

  • Simplex Strainers: Single basket or element chamber; requires system shutdown for maintenance.
  • Duplex/Multiplex Strainers: Multiple basket chambers with valving; allows continuous operation during cleaning.
  • Automatic (Self-Cleaning) Strainers: Provide on-line cleaning options, improving maintenance efficiency.

• Classification Criteria:

  • Pressure ratings
  • Port connections and alignments
  • Cover closure types
  • Basket or element designs and materials
  • Valve types in duplex units

• Material Requirements:

  • All pressure-retaining components must comply with ASME standards for mechanical and chemical durability.
  • Corrosion-resistant materials required for components exposed to fluids.

• Testing and Certification:

  • Mandatory hydrostatic (or air, in specific cases) testing for leak assurance
  • Minimum burst and differential pressure requirements for strainers and baskets
  • Certification and traceability through mark plate and documentation

Applications

Pipe line strainers specified under ASTM F1199-21 play a vital role in protecting pumps, valves, and downstream equipment by mechanically filtering solid particles from fluids. Common application scenarios include:

• Marine Engineering: Protects essential systems such as ballast water, cooling, and lubrication circuits from particulate intrusion.
• Industrial Piping Systems: Used in chemical, water treatment, and process piping to prevent equipment fouling.
• Oil and Gas Facilities: Maintains purity of process fluids in low-pressure pipelines.
• HVAC Systems: Ensures reliable operation of chillers and boilers by removing debris from circulating water.

Simplex strainers are favored where periodic maintenance is feasible, while duplex and automatic strainers are chosen when uninterrupted operation is critical.

Related Standards

Several other standards are frequently referenced alongside ASTM F1199-21 to ensure comprehensive compliance in design and operation:

• ASTM F1200: Specification for welded pipeline strainers used above 150 psig and 150°F.
• ASME Standards:
  • ASME Boiler and Pressure Vessel Code, Section VIII, Division 1
  • ASME B31.1 (Power Piping) and B31.3 (Process Piping)
  • ASME/ANSI B2.1, B1.20.1, B16.1, B16.3, B16.4, B16.5, B16.11, B16.15, B16.24, B16.25
