Carbon steel
flanges are an indispensable part of pipeline connection. According to the
standard, they are divided into JIS BS DIN ANSI Italian standard. Flange
standards are widely used, 10kgs and 16kgs, pressure carbon steel flanges are
the most conventional and most popular. , and are commonly used flanges.
The biggest use of flanges is as a way to
connect pipes, valves, pumps and other equipment to form a piping system. It
facilitates the cleaning, inspection and maintenance of pipes. Reduced
engineering costs.
Weld the flange evenly with the pipeline,
and then fasten the connection with bolts to effectively connect the pipeline,
valve, pump and other equipment accessories, so that the entire pipeline is
integrated and starts to work normally.
It is the most widely used pipe fittings in
the piping system and equipment of machinery, petroleum, chemical industry,
water conservancy, electric power, shipbuilding, air conditioning and other
departments.
Our flanges are standardized in materials,
finely processed, and priced in line with market demand. According to the needs
of different markets and different customers, special shaped manufacturing can
fully meet the requirements of customers and markets for different flanges. And
we will inform customers of market needs so that they can quickly expand the
market.
Type of flange:
According to the
process, it can be divided into:
forged flange,
cast flange, steel plate flange
According to the
shape, it can be divided into:
FF flange, RF flange, BLIND flange, SLIP-ON
flange, Welding NecK flange,
Threaded flange, SocketWeld flange.
According to the
pressure can be divided into:
PN16.
PN10. PN25, PN40, PN60, PN100,
According to the
material can be divided into: carbon steel flange, stainless steel flange,
alloy steel flange
Flange production
process:
1) a: Forged
flange
Saw billets of
different specifications and models into flange blanks, add them to a
reverberatory furnace and heat them to 1000 degrees to take out, and then forge
the flange blanks into ring flanges by forging machines such as forging presses
and air hammers,
b: steel plate
flanges
Put the steel
plate into the punching machine, put it into the corresponding mold, and
directly punch it into a ring flange blank.
c: cast flange
Put the low carbon
steel standard scrap into the intermediate frequency furnace and heat it to
1200-1500, pour it into the mold
The type is a ring
flange blank.
2) The formed ring
flange blank is processed into a ring flange on a CNC machine tool according to
the drawing, and then the flange is drilled with a CNC drilling machine
according to the drawing requirements, and the finished product is completed.
3) For the
finished flange product, the thickness, hole diameter, center distance, inner
and outer diameter of the flange shall be inspected according to the drawing
requirements.
4) The flanges
that have passed the inspection will be typed on the end face of the flange
according to the customer's requirements, and the flange will be treated with
anti-rust treatment according to the customer's requirements, 1: paint, 2:
anti-rust oil, 3: galvanized, and then install it. In wooden box for shipment.
