What does SORF flange mean?

slip on raised face flange
SORF stands for slip on raised face flange, Flange SORF A105 is thus manufactured by most of the steel industry. Materials and grades of slip on flange includes, stainless-steel slip-on flanges, duplex and super duplex steel slip on flanges, alloy steel slip on flanges and many more.

What is WNRF flange?

What is Weld Neck Flanges? The Welding Neck Flanges (WNRF) are often used for high-pressure applications. To order a weld neck flange, it is important to specify the pipe is being used for. This is because the inside diameter of the flange will match the inside diameter of your pipe or Fitting.

What is the difference between slip on and weld neck flange?

The Weld Neck Flange offers increased strength under higher pressures, subzero or elevated temperatures that cause line expansion or retraction or other variable forces. The Slip On Flange is designed to be welded to pipe then a fitting as fittings are designed for butt weld connections.

What are the different types of flanges?

Most commonly used flanges are weld neck flange, slip on flange, blind flange, socket weld flange, threaded flange and lap joint flange (RTJ Flange). This type of connection in a pipe flange allows for ease of disassembly and separation for repair and regular maintenance.

What does WNRF mean?

WNRF. Weld Neck Raised Face (flange type)

Where is SORF flange used?

Slip on (SORF) Designed to be used in low temperature, low pressure processes, slip on flanges are favoured by engineers in the oil and gas industry due to their economical value in comparison to the wnrf.

What is the difference between RF and RTJ flange?

Answer: RF means “Raised Face.” RTJ means “Ring Type Joint.” RF flanges seal with a flat gasket, formerly made of asbestos but now made of more environmentally friendly material, designed for installation between the raised faces of two mating flanges (both with raised faces).

Can you weld a slip on flange to a 90 degree elbow?

There is no Code restriction against welding a Slip-On (SO) Flange directly to an elbow, a Reducer, a Tee or any other fitting.

Can slip on flange connect to weld neck flange?

This is because a slip on style flange will accept a pipe with a fillet weld connection, whereas a weld neck flange will have a reinforced hub at the base and form a weld bevel connection directly to the butt weld end of a pipe. This tapered hub allows for stronger service in a mechanical stress environment.

What is the difference between RF and FF flange?

Flat face (FF) flanges are similar to the RF flanges, but they do not have the raised area like the RF flange. Instead, the whole surface is flat. They are commonly used in low temperature and pressure environments such as pump suctions or water treatment flanges.

What is slip on raised face flange?

Stainless Steel Slip On Raised Face Flanges is referred to as a raised face because the gasket surfaces are raised above the bolting circle face. Carbon Steel Slip On Raised Face Flanges are manufactured with an inside diameter that is slightly bigger than the pipe’s outside diameter.

What is the difference between SWRF and SWRF?

WNRF stands for weld neck raised face flange, SORF stands for slip on raised face flange and SWRF stands for socket weld raised face flange each has to do with the mechanical joint as it relates to attaching each to the piping itself.

What is the difference between slip-on flanges and SWRF flanges?

Slip-on flanges are limited to moderate services where major shocks or extreme pressure and temperature fluctuations will not be present. SWRF[SOCKET WELD RAISED FACE FLANGES]: are more popular than screwed flanges in small sizes. It has a recess extending pipe, way through the flange bore, into which the pipe fits.

What is the design temperature for a sORF flange?

I have an SORF flange, which will bolted onto a WNRF flange, both cl. 300. Design temps around 350 C, 17.5 bar design pressure, medium is N2/H2/light hydrocarbons. Spiral wound gasket with inner and outer ring to be used. Design code B31.3, normal fluid service.

Can You bolt a rfwn to a rfso flange?

There is no problem bolting a Raised Face Weld Neck (RFWN)flange to a properly welded Raised Face Slip On (RFSO) flange. Thanks pennpiper.
