Meta Description
Understand ASME B16.5 flange standards, including dimensions, pressure classes, and materials, and learn why they are critical for safe piping systems.


Introduction

When selecting flanges for industrial piping systems, compliance with ASME B16.5 standards is essential. This standard defines the dimensions, materials, pressure classes, and tolerances of pipe flanges. As a result, it ensures compatibility and safety across industries worldwide.

At DLSS, we manufacture forged stainless steel flanges strictly in accordance with ASME B16.5, providing our clients with confidence in every connection. For a closer look at our products, see our DLSS Flanges Product Page.


Scope of ASME B16.5

ASME B16.5 is one of the most widely used flange standards in the world. It covers:

Therefore, engineers can select flanges knowing they will match existing piping systems manufactured to the same standard.


Pressure Classes Explained

One of the most important aspects of ASME B16.5 is pressure class rating. These ratings define the maximum pressure and temperature conditions that a flange can handle.

In addition, the choice of material (such as stainless steel 304L, 316L, or Duplex) also affects pressure-temperature performance.


Flange Face Types in ASME B16.5

The standard defines several face configurations, each with different sealing capabilities:

As a result, engineers can select the right face type for both sealing performance and system compatibility.


Benefits of Using ASME B16.5 Flanges

Choosing flanges manufactured to ASME B16.5 brings several advantages:
