Types of Slip On Flanges

Standard Slip-On Flanges

Standard or raised-face SO flanges have a raised face on the sealing surface. This feature provides a platform for the gasket, ensuring a reliable seal between the flange and the adjoining pipe or fitting.

Lap Joint Slip-On Flanges

Lap joint SO flanges have a flat face with a separate backing flange. The backing flange slides over the pipe end and aligns with the lap joint stub end, which is then attached to the pipe.

Key Features of Slip On Flanges

Design:
Slip-on flanges have a flat face and are typically welded to the pipe after being slipped over it. This design allows for easy alignment and installation.

Installation:
They are easier to install compared to other flange types, as they do not require precise alignment of the pipe ends. The flange can be positioned and then welded in place.

Applications:
Slip-on flanges are commonly used in low-pressure applications and are suitable for various industries, including oil and gas, water treatment, and chemical processing.

Cost-Effectiveness:
Generally, slip-on flanges are more cost-effective than other types of flanges, such as weld neck flanges, due to their simpler design and installation process.

Material:
They can be made from various materials, including carbon steel, stainless steel, and other alloys, depending on the application requirements.

Limitations:
While slip-on flanges are versatile, they may not be suitable for high-pressure applications due to the potential for leakage at the weld joint.
