ASTM D2464 is a standard specification established by the American Society for Testing and Materials (ASTM) for threaded poly(Vinyl Chloride) (PVC) plastic pipe fittings, Schedule 80, related to all male MNPT and female FNPT threaded fittings. These D2464 NPT threaded fittings are used in pressure systems, where threaded connections are required. The standard specifies the requirements for the material, dimensions, pressure ratings, and testing criteria to ensure the fittings' quality and performance.

Key Points of ASTM D2464 NPT:

  1. Material: The fittings are made from PVC, which has high mechanical strength and resistance to corrosion, making it suitable for various pressure applications.
  2. Schedule 80: This refers to the thickness of the pipe walls. Schedule 80 fittings have thicker walls compared to Schedule 40, allowing them to handle higher pressure levels.
  3. Threading: ASTM D2464 specifies that the fittings should have tapered pipe threads (typically National Pipe Thread or NPT), which are commonly used to provide a leak-tight connection when properly tightened.
  4. Pressure Rating: The standard ensures that the fittings can withstand specific pressure levels depending on their size and the material used.
  5. Testing: Fittings conforming to ASTM D2464 undergo pressure tests to ensure their reliability under specified conditions.

Common Applications:

  • Industrial Systems: Used in water treatment plants, chemical processing, and other systems where higher pressure levels are required.
  • Plumbing: Employed in residential and commercial plumbing systems, especially where threaded joints are necessary.
  • Irrigation: Often utilized in agricultural systems where durable and high-pressure fittings are needed.

Importance of Compliance:

Adhering to the ASTM D2464 standard ensures that the PVC fittings are manufactured to meet specific quality, safety, and performance criteria. It also provides a reliable benchmark for comparing different products, ensuring that they can be used safely in pressure systems.

In summary, ASTM D2464 is the go-to standard for threaded Schedule 80 PVC plastic fittings used in high-pressure systems, ensuring durability, reliability, and performance in various applications
