Threaded Flanges are also known as screwed flange, and it is having a thread inside the flange bore which fits on the pipe with matching male thread on the pipe. This type of joint connection is speedy and simple but not suitable for high presser and temperature applications. Threaded Flanges are mostly used in utility services such as air and water.
☑ Threaded Flange mostly used in utility services such as air and water
☑ It is not suitable for high presser and temperature applications
☑ It also available in limited Size of NPS 4” and below
☑ Threaded Flanges can be FF or RF
☑ It is a Low-cost flange.
|Socket-Weld Flanges has a female socket in which the pipe is fitted. Fillet welding is done from outside on the pipe. Generally, it is used in small bore piping and only suitable for low pressure and temperature application.
☑ Socket-Welded Flanges can be FF or RF
☑ The cost of flange and fabrication is moderate.
Slip-On flange has a hole with matching outside diameter of pipe from which pipe can pass. The flange is placed on pipe and fillet welded from both inside and outside. Slip-On Flange is suitable for low pressure and temperature application.
☑ This type of flange available in large size also
☑ It can be FF or RF
☑ The cost of flange and fabrication is moderate.
Lap flange is having two components, a stub end, and a loose backing flange. Stub end is butt-welded to the pipe and Backing flange freely moves over the pipe. The backing flange can be of a different material than stub material and normally of the carbon steel to save the cost. Lap flange is used where frequent dismantling is required, and space is constrained.
☑ The backing flange can be of a different material than stub material and normally of the carbon steel to save the cost.
☑ This flange provides better joining due to butt-weld as compared to a socket and threaded type flanges
☑ Not suitable for small size, Costly components, and fabrication as compared to threaded, slip-on, and socket flange.
☑ Lap flange provides connection flexibility as you can freely rotate the flange on the pipe. It is used where frequent dismantling is required, and space is constrained.
Weld neck flange is the most widely used type in process piping. It gives the highest level of joint integrity due to Butt-welded with a pipe. These types of flanges are used in high pressure and temperature application. Weld neck flanges are Bulky & costly with respect to other types of the flange.
☑ High skill is required for fabrication and also required more space to accommodate in the piping system due to the long hub.
☑ Weld Neck Flange is available in all sizes & it can be FF, RF or RTJ type
☑ You can see the Weld Neck flange welded with pipe
The blind flange is a blank disc with a bolt hole. These types of flanges are used with another type of flange to isolate the piping system or to terminate the piping as an end. Blind flanges are also used as a manhole cover in the vessel.
Reducing flange is used in place of a standard flange to allow for a change in pipe size. This flange eliminates the need for a standard reducer in piping. The flange consists of one specified diameter with a smaller diameter bore size.
Except for the bore and hub dimensions, a reducing flange has dimensions of the standard pipe flanges size and is considered an economical means to make a pipe size transition.
These flanges are available in weld neck, slip-on, and threaded end types. Reducing flanges are an economical way to make transitions between pipes of different sizes, however, due to high-pressure loss, they are rarely used in piping. ASME B16.5 covers the dimensions of reducing flanges.
It is similar to a weld neck flange but increases the size of the pipe to the first or second larger size. It is an alternative to using reducer and weld neck flange. Useful for connecting to valves, compressors, and pumps.
These flanges are specially designed. Dimensions of the weld neck are in line with the connecting pipe, other dimensions are in accord with standard ASME B16.5 flanges.
Flangeolet is a combination of olet (mainly weldolet or nipple) and flange. As you can see in the image that hub length is longer like long neck weld flange. It is a 90 Degree branch connection use for high-pressure piping.
It reduces the two weld joints than the traditional Olet + Pipe + Flange connection and one weld joint in case of Olet + Flange connection. You can see the image of the flangeolet branch.
