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 in required during plant operation.
A flanged joint is composed of three separate and independent although interrelated components; the slip on flanges, the gaskets, and the bolting; which are assembled by yet another influence, the 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 used flange connection slip on flanges underground piping when it supposed to be buried.
Pipe Flanges – A complete Guide for Engineer
The flange is also a most common source of leak and fire in a process plant. There are variety slip on flanges flanges available to suit the requirements.
Flanged can be slip on flanges in several alternate ways as follows: 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. 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. Slip-On Flanges 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. Below you will find a short description and definition of each type, completed with an detailed image.
Most common flange types Welding Neck flange Welding Neck Flanges are easy to recognize at the long tapered hub, that goes gradually over to the wall thickness from a slip on flanges or fitting.
The smooth transition from flange thickness to pipe or fitting wall thickness effected by the taper is extremely beneficial, under conditions of repeated bending, caused by line expansion or other variable forces.
These flanges are bored to match the inside diameter of slip on flanges mating pipe or fitting so there will be no restriction of product flow. This prevents turbulence at the joint and reduces erosion.
They also provide excellent stress distribution through the tapered hub and are easily radiographed for flaw detection. Details of Welding Neck flange 1. Weld Neck flange 2.
The connection with the pipe is done with 2 fillet welds, as well at the outside as also at the inside of the flange. The X measure on the image, are slip on flanges This space is necessary, to do not damage the flange face, during the welding process.
A disadvantage of the flange is, that principle always firstly a pipe must be slip on flanges and then just a fitting. Details of Slip On flange 1. Slip On flange 2. Filled weld outside 3.

Filled weld inside 4. The connection with the pipe is done with 1 fillet weld, at the outside of the flange. But before welding, slip on flanges space must be created between flange or fitting and pipe.
