A Quick Guide to ASME B16 Standards for Piping Components

This document provides a concise overview of key ASME B16 standards relevant to piping components.


  • Face-to-face and end-to-end dimensions: B16.10, B16.11, B16.34
  • Flanges and flanged fittings: B16.5, B16.47
  • Buttwelding fittings and ends: B16.9, B16.25
  • Gaskets for flanges: B16.20, B16.21
  • Line blanks: B16.48
  • Pipe threads: B1.20.1, B1.20.2M
  • Welded and seamless pipe: B36.10M, B36.19M
  • Bolted flange joint assembly: PCC-1

Key Points:

  • B16.10: Face-to-face and end-to-end dimensions for valves, ensuring interchangeability for specific sizes and ratings.
  • B16.11: Socket welding and threaded forged fittings, with pressure ratings and dimensional specifications.
  • B16.20: Metallic gaskets for flanges, including ring-joint, spiral-wound, and jacketed types.
  • B16.21: Nonmetallic flat gaskets for flanges, with diverse types and dimensional requirements.
  • B16.25: Preparation of buttwelding ends for piping components, including bevels, shaping, and internal end preparation.
  • B16.34: Flanged, threaded, and welding end valves, covering pressure-temperature ratings, dimensions, materials, and testing.
  • B16.47: Large diameter steel flanges (NPS 26-60), with pressure-temperature ratings, materials, dimensions, and testing requirements.
  • B16.48: Line blanks for installation between flanges, with pressure-temperature ratings, materials, dimensions, and testing specifications.
  • B1.20.1 and B1.20.2M: Pipe threads for general purpose applications, in inch and metric versions.
  • B36.10M and B36.19M: Welded and seamless wrought steel pipe and stainless steel pipe, respectively, with standardized dimensions.
  • PCC-1: Guidelines for pressure boundary bolted flange joint assembly, providing procedures for safe and effective flange connection.


  • These are just some of the many B16 standards available.
  • Always consult the relevant standard for specific details and requirements.
  • Choosing the correct standard ensures compatibility, safety, and performance in your piping system.
