What is Slip-On Flanges
Slip-on flange is a pipe connection fitting and a type of random flange. ‌It is connected to the container or pipe through a fillet weld and is designed to be either integral or loose flange. The flange rings of slip-on flanges are of two types: with neck and without neck.
Compared with necked butt-weld flanges, slip-on flanges have a simpler structure and use less material, but their rigidity and sealing are slightly inferior to necked butt-weld flanges.
Slip-on flanges are widely used in the connection of medium- and low-pressure containers and pipelines.

specifications & characteristics of Slip-On Flanges
This table provides a comprehensive overview of Slip-On Flanges, covering key specifications, characteristics, and additional considerations. Specific details and requirements may vary based on the chosen flange size, pressure rating, and material.
Specification/Feature | Description |
---|---|
Standard | ASME/ANSI B16.5 Slip-On Flange. |
Type | Slip-On Flange – A type of flange with a slightly larger bore than the pipe, which slips over the pipe end and is then welded to provide a secure connection. |
Pressure Ratings | Available in different pressure classes, such as 150, 300, 600, 900, 1500, 2500, etc., to accommodate varying pressure requirements. |
Size Range | Typically available in sizes ranging from 1/2 inches to 48 inches or larger, suitable for various pipe and equipment sizes. |
Materials | ASME/ANSI B16.5 Slip-On Flanges can be manufactured from materials like carbon steel, stainless steel, alloy steel, and more, chosen based on application requirements. |
Facing Types | Common facing types include Raised Face (RF), Flat Face (FF), Ring-Type Joint (RTJ), and Male and Female (M&F) facings, impacting sealing methods. |
Bolt Hole Quantity and Diameter | The number and diameter of bolt holes vary with flange size and pressure rating, facilitating flange connection. |
Connection Method | ASME/ANSI B16.5 Slip-On Flanges are slipped over the pipe end and then welded to the pipe, providing a secure and leak-resistant connection. |
Application Areas | Slip-On Flanges are widely used in industries such as oil and gas, petrochemical, water treatment, and more for connecting pipes to flat-end equipment or vessels. |
Standards and Codes | ASME/ANSI B16.5 Slip-On Flanges adhere to standards set by the American National Standards Institute (ANSI) and nominal pipe size (NPS) standards, such as ANSI B16.5. |
Seal Types | Slip-On Flanges commonly use gaskets or O-rings for sealing, with the choice of seal type depending on the application and pressure rating. |
Accessories and Attachments | Some applications may require additional components such as flange gaskets, bolts, nuts, flange covers, or flange cover gaskets. |
Inspection and Testing | ASME/ANSI B16.5 Slip-On Flanges typically undergo a series of inspections and tests to ensure they meet quality and performance requirements, in compliance with standards. |
Marking and Certification | Slip-On Flanges should be marked with the manufacturer’s identification, size, class, material, and other relevant information. Some flanges may require specific certifications such as PED or ASME. |
Installation and Maintenance | Proper installation and regular maintenance of Slip-On Flanges, including weld integrity, bolt torque, flange face cleaning, and lubrication, are crucial for system integrity and performance. |
Application Standards | In specific industries and applications, there may be industry-specific Slip-On Flange application standards that need to be adhered to for safety and performance. |
