ANSI/ASME B16.5 Class 400 Slip On Flange is a type of slip-on flange that complies with the standards set by the American National Standards Institute (ANSI) and the American Society of Mechanical Engineers (ASME) B16.5.
Features of ASME B16.5 400# Slip On Flange
- Pressure Rating: Class 400, suitable for higher-pressure systems, with specific pressure values varying with temperature.
- Size Range: Typically ranges from 1/2 inch to 24 inches, with specific sizes selected based on pipeline requirements.
- Materials: Common materials include carbon steel, stainless steel, alloy steel, etc., chosen based on the application environment.
- Easy Installation: The slip-on design makes the installation process relatively simple.
Advantages
- Easy Installation: The pipe slides through the flange’s bore and is welded, making the installation process straightforward.
- Cost-Effective: Slip-on flanges are generally more affordable compared to other types of flanges.
- Versatile: Widely used in various industrial applications.
Installation Steps
- Slide the pipe through the flange’s bore.
- Align the pipe and flange to ensure proper positioning.
- Weld the connection between the pipe and flange (typically on both the inside and outside).
- Secure the flange to the mating flange or equipment using bolts.
The ANSI/ASME B16.5 Class 400 Slip On Flange is a standardized slip-on flange suitable for medium to high-pressure pipeline systems, offering advantages such as easy installation and cost-effectiveness.

FAQ
- Slip On Flanges are easier to install and more cost-effective but are generally used for lower-pressure applications.
- Weld Neck Flanges are stronger and better suited for high-pressure or high-temperature applications but are more expensive and complex to install.
- Consider the following factors:
- Pipe size and schedule
- Pressure and temperature requirements
- Material compatibility with the fluid or gas
- Industry standards and regulations.
