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 is available in large sizes also to connect big-bore piping with storage tank nozzles. Normally, these flanges are of forged construction and are provided with the hub. Sometimes, these flanges are fabricated from plates and are not provided with the hub

Slip on Flange is essentially a ring that is placed over the pipe end, with the flange face extending from the end of the pipe by enough distance to apply a weld bead on the inside diameter. The OD of slip on flange is also welded on the back side of the flange.

The X measure on the image, are approximately:
Wall thickness of pipe + 3 mm.
This space is necessary, to do not damage the flange face, during the welding process.

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.

A flanged joint is composed of three components; flanges, gaskets, and bolting; which are assembled by pipe fitter. Special controls are required in the selection and application of all these elements to attain a joint, which has acceptable leak tightness.

 

However, it is not advisable to use a flange connection in underground piping when it supposed to be buried. The flange is also the most common source of leak and fire in a process plant. There are a variety of flanges available to suit the requirements.

As the name suggests, Long Neck Flange has long neck than regular weld neck flange. Other than neck, all the dimensions are same as the regular flanges. It is used as a nozzle in the pressure vessel and heat exchanger.

Long neck has two advantages over the normal pipe to flange connection. First, it does not require pipe piece and second it eliminates, weld between pipe and flange that required in case of conventional nozzle connection. These types of flanges are normally used in high pressure and temperature application. It is costly but gives high reliability and reduces fabrication efforts as compared to normal pipe to flange type nozzle.

Orifice Flanges or ORF are used with orifice flow meter that is why it called orifice flanges. The purpose of orifice meter is to measure the flow rate of either liquids or gasses that pass through the pipe. These flanges are always used in a set of two. Two flanges, Orifice Plate, Gaskets, Pressure taps and Jack screw hole with two jack screws.

Orifice flanges are available from Class #300 to Class #2500. Class #300 flanges are available in threaded, slip-on and weld neck end types. Whereas, Class# 600 and above flanges are available in only weld neck type end connection.  Dimensions of these flanges are covered in ASME B16.36. Orifice plate is a specially designed plate with a hole at center that creates a pressure drop to measure the flow rate. Please note that orifice plate is not interchangeable. It means you cannot use orifice plate of water line into the hydrocarbon line. Size of the hole and the angle, are specifically designed for the service.

There are only two types of flange faces are available in orifice flange. Raised face and RTJ face. Therefore, only spiral wound and RTJ gaskets are used that too in the set of two for each side of the orifice. These jack screws are drilled on the flange circle centerline at 90 degrees to the tapped hole and used to facilitate separating the flanges for inspection or replacement of the Orifice Plate and gaskets.

Tap holes are either tapped  NPT or  NPS socket connection. A one tap hole from each flange is used to connect instruments with the help of tube that allows liquid or gas to reach the instrument. The other one hole is sealed with a plug. Orifice flanges are installed in a straight run of pipe in order to avoid turbulence at the plate. As a rule of thumb, an orifice flange has ten diameters of straight pipe upstream and five diameters of straight pipe downstream. In general pressure taps kept at the same elevation to each other.

The most common material grade used is A105 forged carbon steel, with sizes ranging from 1/2“ – 24” in ASME B16.5, 26” – 60” in ASME B16.47, and 26” – 96” in B16.1 (for temperatures ranging from ambient up to 1,000 Fahrenheit and pressure between 20 – 6,170 psi).

Modern carbon is a common steel with carbon content up to 2.1% by weight and primarily alloyed with iron. The term “carbon steel” may also be used to call out steel which does not have a large amount of chromium or nickel. The carbon content can vary for A105 with a maximum allowable of 0.35 as a percentage composition. As the carbon content increases, the steel hardens and increases in strength through heat treatment processes 

ASTM A105, ASTM A182, ASTM A694, ASTM A516, and ASTM A350 are available

These flanges are available in many types like socket weld flanges, blind flanges, weld neck flanges, and slip-on flanges, etc

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.
The purpose of these is to block off a section of pipe or a nozzle on a vessel that is not used. A nozzle is typically a pipe coming out of a vessel and is usually flanged so it can be connected to valves or piping. Many times a nozzle will be blanked off with a blind flange for pressure tests in a plant, or simply because the customer does not need all the nozzles that were supplied on the tank.

Blind flanges, just like standard pipe flanges, can be raised face RF or flat faced FF. If the flange is RF we would recommend a standard ring gasket that is appropriate for the service and/or test. If it is FF we would TYPICALLY use a full face gasket, because the most common reason the flange is FF is that it is not designed to handle the bending forces that result when using a ring gasket or a RF flange against the FF flange

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.

Lap Joint Flanges have all the same common dimensions as any other flange named on this page however it does not have a raised face, they used in conjunction with a "Lap Joint Stub End".
These flanges are nearly identical to a Slip On flange with the exception of a radius at the intersection of the flange face and the bore to accommodate the flanged portion of the Stub End.
Their pressure-holding ability is little, if any, better than that of Slip On flanges and the fatigue life for the assembly is only one tenth that of Welding Neck flanges.
They may be used at all pressures and are available in a full size range. These flanges slip over the pipe, and are not welded or otherwise fastened to it. Bolting pressure is transmitted to the gasket by the pressure of the flange against the back of the pipe lap (Stub End). 

Lap Joint flanges have certain special advantages:
Freedom to swivel around the pipe facilitates the lining up of opposing flange bolt holes.
Lack of contact with the fluid in the pipe often permits the use of inexpensive carbon steel flanges with corrosion resistant pipe.
In systems which erode or corrode quickly, the flanges may be salvaged for re-use.

The flanges are the second most used joining method after welding. They are used when joints need dismantling. It provides flexibility for maintenance. Flange connects the pipe with various equipment and valves. Breakup flanges are added in the pipeline system if regular maintenance is required during plant operation. A flanged joint is composed of three components; flanges, gaskets, and bolting; which are assembled by pipe fitter. Special controls are required in the selection and application of all these elements to attain a joint, which has acceptable leak tightness.

A flange can be classified in several alternate ways as follows:
Based on Types of Connection
Based on Flange facing Types
Based on Pressure Temperature Ratings
Based on Material Types

 

Flange Types
Threaded Flanges
Socket-Weld Flanges
Slip-On Flanges
Lap Joint Flanges
Weld Neck Flanges
Blind Flanges

Flange Facing Types
Based on Flange facing Types, it can be further classified as
Flat Face (FF)
Raised Face (RF)
Ring Joint (RTJ)
Tongue and groove (T&G)
And Male and Female type

 

Serration on the Flange Face
The flange face has small grooves.  This machining is known as a serration.  Flange faces can be smooth or serrated type. It depends on the type of gasket and service of the fluid.

 

Smooth finish is used with a metallic gasket whereas a serrated finish is used with a non-metallic gasket.  The soft material of gaskets is set in this serration and prevents liquid or gas from passing from the flange joint.

 

Serration can be spiral or concentric rings as you can see in the slide. Concentric rings type finishing is used when fluid is of very low density. If you use spiral type finish with very low-density fluid, it may find a leakage path through the spiral cavity.

Flange Pressure-Temperature Class (Service Rating)
The flange is classified as per their pressure-temperature ratings which are designated as 150#, 300#, 400#, 600#, 900#, 1500# and 2500#. Large diameter flanges that are 24 to 60 are available up to 900# class. Pressure-temperature ratings are maximum allowable working gauge pressures in the bar & the temperatures in degrees Celsius.

 

Higher the rating, heavier the flange and can withstand higher pressure and temperature. When the temperature goes up, the pressure goes down, and vice versa. Please note that different material has different pressure ratings.

Flange Material
Flanges are manufactured from

Carbon steel
Low alloy steel
Stainless steel
Combination of Exotic materials (Stub) and other backing materials

A flange can also be a plate or ring to form a rim at the end of a pipe when fastened to the pipe (for example, a closet flange). A blind flange is a plate for covering or closing the end of a pipe. A flange joint is a connection of pipes, where the connecting pieces have flanges by which the parts are bolted together.

 OD AND DRILLING for 30& 36 pipe size per ASME/ANSI B16.1-1989 Class 125

 

The ANSI B16.5 Class 150 Plate Flanges are meant for both Pipe systems as well as Flanged Fittings. The specification for the ASME B16.5 Plate Flanges covers, dimensions, tolerances, marking, testing, pressure &temperature ratings, materials including methods of designating openings for flanges and flanged fittings in pipe systems. The following points are included:

 

Plate Flange with pressure rating class designations i.e. class 150, class 300, class 400, class 600, class 900, and class 1500 in a size range between NPS 1/2 up to NPS 24 & Alloy Steel Plate Flanges with pressure rating class designation class 2500 is available in sizes NPS 1/2 till NPS 12.

The requirements of the ASME B16.5 Plate Flange has been given in both metric as well as the U.S. Customary units with diameter of bolts and Plate Flange Dimensions bolt holes expressed in inch units;

Flanged fittings with rating class designation class 400, class 600, class 900, and class 1500 in sizes NPS 1/2 through NPS 24 and ANSI B16.5 Plate Flanges fittings with rating class designation with Stainless Steel Plate Flanges class 2500 in sizes NPS 1/2 up until NPS 12. These have been acknowledged in the specification in Non-Mandatory Appendix E section of the Flat Faced Plate Flanges in which only U.S. Customary units are provided.

ASME B16.5 Plate Flange has been limited to flanges and flanged fittings made from materials such as cast or forged materials. While blind flanges and certain reducing flanges could be manufactured from other metals such as cast, forged, or plate materials are exported by plate flange manufacturers. Also included in this Standard are requirements and recommendations regarding the ASME B16.5 Plate Flange for bolting, flange gaskets, as well as flange joints.

This Standard is to be used by ASME B16.5 Plate Flange manufacturers in conjunction with equipments that have been mentioned in other volumes of the Standards in ASME B16 Series as well as with other ASME standards. Therefore, the ASTM A182 SS Plate Flange could be used for both the Boiler and Pressure Vessel Code as well as the B31 Piping Codes.

PN is an acronym for Pressure Nominale. The PN is used as a prefix to the pressure rating of the Flanges. ... Following international flange standards such as ISO 7005-1 or DIN 2501, PN10, PN16, PN25, and PN40 specify both pressure class in pressure bars and metric flange dimensions that use the metric measuring system
EN 1092-1 is for steel flanges, EN 1092-2 is for iron flanges, EN 1092-3 is for alloy flanges, EN 1092-4 is for aluminum alloy flanges. PN stands for Nominal Pressure and roughly equates to the number of bars i.e. the cold working pressure of PN10 is 10 bar. Ratings range from PN2. 5 to PN420
The Term PN is a Flange standard, they specify the pressure class in bar and metric standard following the metric dimensions. In general Flanges are used for connections with Equipments or Inter connections between the Metallic and Non metallic
