Various Stainless Steel Flanges Manufactured in Mumbai India
Slip On Flanges
Slip
on Flange Is fundamentally a ring placed over the end of the pipe, with a
flange face extending from the end of the pipe by sufficient distance to apply
a welded bead to the inner diameter. As the name suggests these flanges slip
over a pipe & hence known as Slip On Flanges. A slip-on flange is also
known as SO flange. It’s a kind of flange that are slightly bigger than the
pipe & slides over the pipe, with internal design. Since the inner
dimension of the flange is slightly bigger than the external dimension of the
pipe, the top & bottom of the flange can be connected directly to equipment
or pipe by fillet welding the SO flange. It is used to insert the pipe into the
flange’s inner hole. Slip-on pipe flanges are used with a raised or flat face. Slip-On
Flanges are a suitable choice for low-pressure applications. Slip on flange is
excessively utilized in many fluid pipelines. Slip On Flanges

Weld
Neck Flange also known as a tapered hub flange or high-hub flange. Weld neck
flange (WN flange) has a neck that can move the pipe tension, thereby reducing
the pressure gathered in the bottom of the flange. It is compatible with the
pipelines which operate at high or low temperatures & withstand high
pressure. Welding Neck Flanges are effortlessly identifiable at the long
tapered end, which slowly passes through the wall thickness from a pipe or
fitting. The long tapered hub provides significant shielding for use in
multiple applications involving high pressure, sub-zero &/or high
temperatures. A weld neck flange comprises of a circular fitting with a
protruding edge around circumference. Weld Neck Flange has been used
successfully at pressures up to 5,000 psi. Weld Neck Flanges

The
Socket weld flanges are only connected on the outside by one fillet weld, &
are often not advised for critical services. These are mostly used for the
small-bore lines. Their static strength is equivalent to Slip On flanges, but
their fatigue strength is 50 percent higher than double-welded Slip On flanges.
For this type of flanges, the thickness of the connecting pipe should be
defined to ensure proper bore length. Before welding, a gap must be formed in
the socket weld flange between the flange or fit & the pipe. The objective
of a Socket Weld’s bottom clearance is generally to minimize the residual
pressure at the weld root that could occur during weld metal solidification.
The socket weld flange’s drawback is the right space, which must be made. The
crack between the pipe & the flange can cause corrosion problems by
corrosive products, & mostly in stainless steel pipe systems. This flange
is not allowed in some processes. Also for this flange, that principle must
always be welded first by a pipe & then simply by a fitting. Socket Weld Flanges

Spectacle
Blinds are typically used for permanently splitting pipe networks, or simply
for connecting to each other. A Spectacle Blind is a steel plate which has been
cut into two discs of a certain thickness.
The
two discs are connected to each other by a part of steel similar to the piece
of a pair of glasses on the nose. The name derives from the fact that the
assembly looks like eyeglasses or “spectacles.” One of the discs is a solid
plate, while the other is a ring who’s an inner diameter equivalent to that of
a flange. Spectacle Blinds are used in structures that need to be segregated
from other installations on a regular basis. The Spectacle Blind is usually
installed in the “open” position so that the flow through the pipe is feasible.
If the Spectacle Blind is rotated in the “close” position, the pipe is blanked
off & no flow is feasible. Blind FlangesManufacturer in India
