Overview

ASTM D2517-18(2023) is the standard specification developed by ASTM International for reinforced epoxy resin gas pressure pipes and fittings. This standard sets forth requirements and testing methods to ensure the quality, performance, and reliability of pipes and fittings designed for gas distribution, particularly in applications where corrosion resistance, toughness, and protection against gas permeation are essential. The specification applies to products intended for direct burial and insertion in gas supply networks handling natural gas, petroleum fuels (propane–air and propane–butane vapor mixtures), and various manufactured and mixed gases.

Key Topics

• Material Requirements: Covers the use of glass fiber-reinforced epoxy resin, specifying the types, grades, and classes suitable for gas pressure pipes and fittings.
• Dimensions and Tolerances: Establishes dimensional tolerances for outside diameter, wall thickness, and fitting compatibility to ensure product interchangeability and correct assembly.
• Performance Testing: Includes methods and criteria for testing:
  • Hydrostatic burst strength
  • Chemical resistance
  • Longitudinal tensile strength
  • Crush (parallel plate) strength
  • Hydrostatic collapse capability
• Adhesive Requirements: Specifies that adhesives used for joining pipes and fittings must meet minimum shear strength requirements and that proper labeling and usage instructions are provided.
• Marking and Traceability: Mandates detailed product marking, including manufacturer information, size, material codes, standard designation (ASTM D2517), and date of production for traceability.
• Quality Control: Recommends an in-plant quality control program, with routine sampling and testing, to ensure compliance with standard requirements.

Applications

Reinforced epoxy resin gas pressure pipes and fittings specified under ASTM D2517 are primarily used in:

• Natural Gas Mains and Services: Ideal for underground distribution systems where durability and resistance to environmental factors are critical.
• Petroleum Fuel Distribution: Suitable for transporting vapor mixtures such as propane–air and propane–butane, where chemical resistance and toughness are required.
• Mixed and Manufactured Gas Pipelines: Utilized in systems conveying various industrial gas compositions, where permeation resistance and long-term property retention are vital.
• Direct Burial and Insertion Installations: Designed for scenarios where pipes must withstand earth loads, minimize corrosion risk, and be easily joined using adhesives or mechanical fittings.

These pipes and fittings are often selected over metallic alternatives in corrosive environments or where lightweight, flexible installation is advantageous.

Related Standards

ASTM D2517 references several other ASTM standards essential for testing and installation, including:

• ASTM D2996: Filament-wound glass-fiber thermosetting resin pipe specification
• ASTM D1599: Resistance to short-time hydraulic pressure of plastic pipes
• ASTM D2105: Test method for longitudinal tensile properties
• ASTM D2412: Parallel-plate loading test for pipe stiffness
• ASTM D543: Chemical resistance of plastics to reagents
• ASTM D618: Plastic specimen conditioning for testing
• ASTM D3567: Determining dimensions of fiberglass pipes and fittings
• ASTM D3839: Guide for underground installation of fiberglass pipes

Note

As of this 2023 revision, there is no known ISO equivalent to ASTM D2517, highlighting its unique position in international standards for reinforced epoxy resin gas pressure piping systems.
