What is a SORF Flange?
SOFR flanges are essential components of many pipelines, machines and other equipments. A SORF flange (Slip On Raise Face) is a type of flange that is designed to be easily installed with welding or bolting. It comprises four parts– two raised faces, a hub bore, and bolts or studs used to hold the flange in place. The raised faces provide connections for connecting pipes while the hub bore allows them to be accurately aligned when necessary. The full form of SORF flange is slip on the raised face flange. Slip-on raised face flanges used with pipe (by weld) for connect the two different pipe. This type of flange is available with a variety of size and specification and used accordingly to its application. This type of flange connects with the pipe by the help of fillet welding at the hub and end of the pipe inside of the flange. The SORF flange is available in raised face, plain, and RT J faces and orifice configuration also. It is easy to fit and weld with different types of pipe specification. There are very important types of pipe fitting like Olets, Weldolet, Sockolet, Threadolet, elbows, gasket, pipe, reducer and others.

In this guide, we will explain the different types of SOFR flanges, their specifications and how they should be installed correctly. We will also explore the benefits that these flanges offer and how they can help to increase performance and reliability.
Components of the SORF Flange
A SORF flange consists of four components – two raised faces, a hub bore, and bolts or studs. The hub bore is the center section of the flange that has the diameter equal to the outside diameter of the pipe. The raised faces provide connections for connecting pipes and can be either flat face (FF) or raised face (RF). Finally, bolts and studs secure the flange in place when necessary.
Identifying SORF Flanges
SORF flanges are identified by their size, type of hub bore, pressure rating, and face type. To identify a SORF flange correctly, the dimensions for each respective component should be measured and compared to a standard reference guide. Additionally, it is important to determine the bolt circle diameter – which is the distance from the center of one bolt hole to another – as this will affect the compatibility between different flanges.
Installation and Maintenance of SORF Flanges
Installing and maintaining SORF flanges requires expertise and knowledge regarding their components and specifications. Proper handling of the components is essential when attaching them to a pipe, as incorrect installation can result in improper fitting and potential leakage. Regular maintenance should also be practiced, such as checking for leaks or corrosion, in order to avoid any safety hazards. When installing and maintaining SORF flanges, it’s important to use the correct tools for the job and ensure that all bolts are tightened evenly.
Safety Considerations for SORF Flanges
When working with SORF flanges, it is essential to practice proper safety precautions. Make sure all bolts, studs, and other components are tightened correctly according to the manufacturer’s instructions. It is also important to use approved protective gear when working around a sharp edge or high temperature areas. Never operate the flange without the proper training or wearing of protective equipment such as gloves and eyewear. Lastly, always check for leaks and corrosion regularly. Bolt flange selection chart

A SORF Flange is a specialized type of pipe flange commonly used in engineering projects such as those involving hydraulic systems and piping connections. In this article, we’ll take an in-depth look at the uses of a SORF Flange, how it works, and some of the advantages and disadvantages associated with it.
Introduction to SORF Flanges
A SORF Flange is a compact and lightweight flange designed specifically for use in engineering projects. It is constructed from stainless steel or other metals and can be used to create a secure connection between pipes. The flange works by providing the sealing surface or contact points required for efficient performance of the pipe system. With its small size, it makes it easy to use in large projects where space is at a premium. Sorf flanges are suitable for low-pressure and high pressure applications, and it is also used for low and high temperature applications.
Components of a SORF Flange
A SORF Flange contains five main components – the body, face, bolt holes, retaining screws, and a gasket. The body is designed to fit both ends of the pipe that requires sealing whereas the face provides a seal between both sides of the pipe. Bolt holes on the flange hold it in place while retaining screws are used to ensure tightness and security. Lastly, a gasket placed between both faces is responsible for creating a leak-proof seal in order to guarantee no further leakage when operating at pressure levels.
Working Principles of a SORF Flange
SORF Flanges are designed to provide a tight, leak-proof seal when two pipe ends need to be connected. This is achieved through the flange’s body shape, services bolts and gasket. When clamped together, the bolts keep the unit firmly in place, while the gasket creates an impermeable layer between both faces preventing any further leakage of liquids or gases through the connection.
Uses and Applications of a SORF Flange
SORF Flanges are widely used in engineering and construction projects, due to their versatile applications. They are suitable for connecting and sealing off both metal and non-metal pipes of different sizes and shapes. SORF flanges are also resistant to heat and impacts from vibrations, meaning that they can be used in a variety of settings, ranging from industrial plants to plumbing systems at home.
Advantages and Benefits of Using a SORF Flange
SORF Flanges are cost-effective and highly reliable, making them a great choice for any project involving pipe fittings. They are easy to install with just a few basic tools, and they are designed to be leakproof, ensuring that no liquids can escape. Additionally, since they are made of high-grade material, they provide excellent resistance to heat and vibration transmissions. This ensures long-term performance and safety during operation.
ANSI B16.5 Slip On Flanges Application
A Slip-On Flange (SOF) is a type of flange designed to be installed onto a pipe by slipping over the pipe’s end and connecting with fillet welds. They are usually manufactured according to ASME B16.5 standards and can be made from various materials, such as carbon steel, stainless steel, nickel alloys or others. SOFs are commonly used in applications involving high pressure and temperature due to their superior sealing capabilities.

A slip on flange (SO flange) is a type of pipe flange which is slipped over the pipe and welded in place. It can be manufactured to meet different industry standards such as ANSI B16.5, MSS SP44, ASA, API-605, AWWA and DIN Standard ND-6, 10, 16, 25,
SORF flanges, also known as Slip On Plate Flanges, are standard components used in assemblies for flanging pipes or pump lines and come in two types: ASME B16.47 Series A and B. SORF flanges are the perfect way to join pipes or pump lines together with a secure fit and are known for their robust and reliable construction. They can be used in a wide range of applications, making them an essential choice for engineering and piping systems.
SORF flanges are used in a variety of applications and are known for their excellent strength and durability. They are available in two types: Series A and Series B, and come in titanium, ASME B16.47, Inconel, and ANSI B16.5 varieties. SORF flanges are designed to be slipped on the end of pipes and other devices to secure them together or to provide access points for maintenance or connection of new components.
Slip on flanges (also known as SOFs or SOFFs) are commonly used in water supply systems due to their simple and economical design. They consist of a flat ring with a radial groove cut into it, which is designed to fit onto the end of a pipe. The flange is typically secured to the pipe using bolts through its four mounting holes, ensuring a tight and secure connection.
