Features of Class 150 Slip On Flanges
- Design: The Slip On Flange slides onto the pipe’s outer diameter and is secured by welding.
- Usage: Primarily used in low-pressure systems, and its simple design makes it easier to install.
- Materials: Commonly made from carbon steel, stainless steel, or alloy steel to meet various environmental requirements.
- Applications: Slip On Flanges are commonly found in pipeline transport and process industries, such as water treatment, petrochemical, and chemical industries.
Applications
- Low-Pressure Piping Systems: Suitable for low-pressure and non-critical fluid transportation systems such as water, air, and oil.
- Easy Installation: Due to its slide-on design, a Slip On Flange is easier to install compared to a Weld Neck Flange, although it has slightly lower strength.
Advantages
- Lower Cost: Slip On Flanges are more cost-effective than Weld Neck Flanges.
- Ease of Alignment: Its sliding design makes it easier to align during installation compared to Weld Neck Flanges.
These standard dimensions and specifications help ensure the performance and suitability of Slip On Flanges and ensure compatibility with ASME B16.5 standards.

FAQ
A Slip On Flange is a type of pipe flange that is designed to slide over the pipe’s outer diameter. It is then welded to the pipe on both the inside and outside for a secure connection. It is typically used in low-pressure applications.
Class 150 refers to the pressure rating of the flange. It indicates that the flange is suitable for systems with a maximum pressure rating of 150 psi (pounds per square inch) at ambient temperature.
The Slip On Flange is slid onto the pipe and then welded both internally and externally for a secure connection. This provides additional strength to the joint.
