Slip On Flanges / SORF Flange

Slip on flange is the type of flange that slips on over the pipe. These types of flanges have an inner diameter that is a little bit bigger than the outer diameter of the pipe. Basically, slip on pipe flanges are a ring placed over the end of the pipe and the face of the flange extends from the pipe end. If Type C stub ends or Type B stub ends are used, these types of flanges can also be used as lap joint flanges. Flange slip on type is easier to align and compared to weld neck flanges, the material cost is lesser. On the back of this kind of flange, is welded the OD of this flange.

A stainless steel slip on flange is the kind of flange that has been seamlessly designed from mill plates and stainless steel and these flanges are totally compliant with ASME SA240 and ASTM A240 or ASTM A182 and ASME SA182 standards. These slip on flanges of stainless steel are designed for use in pipe lines of gas industries and oil refineries and for use in low pressure applications in the petrochemical industry. These flanges are leakage proof, they have dimensional accuracy, they offer excellent hardenability, they have optimum weldability and their finish is flawless. A raised face slip on flange is a slip on pipe flange that has a flat face or a face that is raised. In this type of flange, a ring groove has been machined into it. It is known as ‘raised face’ as the surfaces of the gasket are raised above the face of the bolting circle. In applications in process plants, slip on flanges with raised faces are the most commonly used.

A reducing slip on flange is that kind of flange that is used where there is a need to fit together pipes of different sizes. This is the most economical way of mating different sized pipes. These types of flanges are very popular for use in applications that involve the use of low pressure. Carbon steel slip on flanges have a low carbon content and so they are used in non-critical conditions. SA105N is a very good example of a mild Carbon Steel and this is one of the most common of all the Carbon steels and it is also one of the most common of all the steels in the world. It has a low price and it is hard and not ductile or brittle. A PN16 slip on flange has at room temperature, a maximum rating of 16 bar. PN stands for 'pressure nominal' and PN16 specifies the pressure class in metric flange dimensions and also in bars of pressure. A slip on flat face flange is the kind of flange in which the bolting circle face and the gasket surface are in the same plane. Flat face flanges should never ever be bolted to a raised face flange.

A slip on rf flange is so named as the surface of the gasket is raised above the face of the bolting circle. These raised face flanges are very easy to identify and they are used in many different process applications. A slip on blind flange is a blank disc that has a bolt hole. These types of blind flanges are used to terminate piping or to isolate a piping system. In slip on flange welding, the pipe flanges are first slipped on over the pipe and then they are fillet welded. In this process of welding of slip on flanges, the fitting or the pipe is set back from the flange face, at a distance that equals that of the wall thickness -0" +1/16".
