Flanges are used when joints need dismantling. The flange is second most used joining method after welding. It Provides flexibility for maintenance.
Flange connects the pipe with various equipment and valves. We manufacture flanges according to international specifications and standards and also as per drawings provided by the customer.
TYPES OF FLANGES:
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. Threaded Flanges are mostly used in utility services such
as air and water.
Socket-Weld Flanges has a female socket in which 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
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 size also to connect big bore piping with storage tank nozzles.
Lap Joint Flanges
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 move over the pipe. The backing flange
can be of different material than stub material .Lap flange is used where frequent
dismantling is required, and space is constrained.
Weld Neck Flanges
Weld neck flange are most widely used flanged 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.
The blind flange is a blank disc with bolt hole. These types of flanges are
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.
Ring joint type flange has a specially designed grove in which metal gasket seat. This
type of flange is used in high pressure and temperature services.
