Different Factors Used To Identify A Flange
In this
Blog, flanges
manufacturer in India will discuss identifying a flange. Whether
a flange will function correctly all goes back to whether the flange was the correct
one for the job in the first place. A flange must fit in pipe joints just precisely
in order for it to perform appropriately. A minor error in selecting a flange
can affect an application resulting in a costly mistake. These 7 factors are
all involved in selecting the perfect flange for the right application to
maximize its functionality.
Types
It’s quite easy to recognize the type
of flange by how it looks. First, identify the tops by determining
whether a flange has a flat face, threaded bore, lap joint, weld neck, socket
weld, or tongue & groove. Next is recognizing the bottoms by determining
whether it has a flat face, which is wholly flat or a raised face which is a slightly raised section on the
face of the flange.
Size
The size of a flange is comprised
of factors that include the standard used (ANSI
B16.5/DIN/JIS), pressure class needed, & the actual measurements of
a flange. Factors include the outer diameter, inner diameter, number of bolt
holes, bolt hole diameter, & the bolt circle.
Thickness
Thickness
play a vibrant role in recognizing a flange by how high of a pressure it can
withstand because thicker flanges can withstand higher pressures in an
application.
Bolt Holes
This component helps determine the
size of a flange & pressure class. 3 factors that need to be considered are
the number of bolt holes, pitch circle diameter, & actual size of the bolt
holes on a flange. The thicker the bolt the stronger the bolt is, resulting in
a higher pressure that the flange can withstand. Buy flanges from flanges
supplier in India.
Standards
There are a number of standards
that can be selected from. The selection will most likely be based upon
the application & standards of the other components that this flange will
be connected to. (i.e. valves) 3 main standards used are: ANSI – American
National Standards Institute, DIN – Deutsches Institut für Normung / European, &
JIS – Japanese International Standard.
Pressure Class
The pressure class represents the minimal
amount of pressure that the product can support or operate under safely.
Each standard has several pressure classes available ranging from low-pressure
tolerance to high-pressure tolerance. The pressure class of products
working together should be the same matching the pressure class of the pipes &
valves in the system that it is connected to.
